**** BEGIN LOGGING AT Mon May 27 02:59:58 2013 May 27 03:12:02 I am thinking of running ArchLinuxARM-am33x on qemu as a dev platform. I would like to make sure everything i need can compile. May 27 03:12:09 Does that sound right? May 27 03:30:58 Trying to compile systemd-204, but ./ configure experiences error "Package requirements (dbus-1 >= 1.3.2) were not met: No package 'dbus-1' found." opkg list-installed shows dbus-1 - 1.64, dbus is installed in /usr/local/ and that directory is shown by echo $PATH. What should I check next? May 27 03:34:14 configure often looks for the dev packages, not simply the binaries May 27 03:37:57 double checking, but I think a dev package is their, but maybe something is missing or corrupted, i'll take another look May 27 04:03:31 thurgood, I see dbus-1 dbus-systemd May 27 04:05:26 Is it possible to access the host DRAM from the PRU subsystem? May 27 04:17:03 mastiff_: the dev packages contain headers for using the libraries May 27 05:03:23 hey that's great the dbus-dev solved the ./configure issue, it's building now May 27 05:31:29 hello May 27 05:32:30 curious about the wifi adaptor May 27 05:32:42 is it an easy setup May 27 05:33:32 l8ter May 27 05:33:49 patience is a virtue May 27 05:34:00 patience is virtual May 27 05:34:46 and can be found under Applications → Games → AisleRiot May 27 05:37:16 solitaire.exe May 27 06:26:55 Has anbody got Ubuntu core to work on BeagleBone? I can't seem to get the network interface to work after booting May 27 06:28:37 gm May 27 06:29:22 JIHAD! May 27 06:31:05 morning! May 27 06:31:23 there he goes again May 27 06:32:20 * KotH throws a bag at emeb_mac May 27 06:32:25 gah bars suck May 27 06:32:33 mranostay: switch bars May 27 06:32:58 or try foos May 27 06:33:00 stop going to gah bars May 27 06:33:23 that is one typo asking to be done.. May 27 06:34:25 go to ack bars May 27 06:37:17 go home mranostay, you're drunk May 27 06:39:13 i am home May 27 06:39:18 not drunk May 27 06:39:49 so, your home is a gah bar? May 27 06:40:22 no i walk home from the gah bar May 27 06:40:44 why were you in the gah bar in the first place? May 27 06:42:17 because i like drinking, duh? :) May 27 06:43:03 kids these days... May 27 06:43:25 is that like a whiskey bar? May 27 06:47:45 i live in the 'university district' so a few bars around May 27 06:49:29 KotH: i do like meeting people in small amounts too May 27 06:50:09 hi, i just notice it have 2013-05-20 angstrom release for beglebone black. May 27 06:50:17 is it fix the usb hot plug problem? May 27 06:50:33 Littledog_, not that I've heard. May 27 06:50:41 DT design check question: does this make sense? http://www.element14.com/community/community/knode/single-board_computers/next-gen_beaglebone/blog/2013/05/22/bbb--working-with-the-pru-icssprussv2#comment-22620 May 27 06:50:53 thankyou ka6sox. May 27 06:52:26 And can I upgrade my existing angstrom with opkg update/upgrade? May 27 06:52:40 one does not simply... May 27 06:52:42 mhaberler, your scheme is very scary (re: mmaping gpios to user-space) but it should work May 27 06:53:07 panto: sounds like drugs are involved there May 27 06:53:14 the boundary conditions I cannot change unfortunately.. May 27 06:53:20 I don't like the arbitrary mmap of the gpio register space May 27 06:53:28 panto, +1 May 27 06:54:17 if you find a way to do I/O from Xenomai RT threads without it, I'd be interested - but chances are next to 0 May 27 06:54:38 what kind of I/O do you need? May 27 06:54:44 Littledog_, the *only* way currently is to download the flasher for 5.20 and use that May 27 06:54:50 if "system" calls are not allowed, having a "system" is kinda moot May 27 06:55:00 otherwise it overflows the eMMC. May 27 06:55:34 there are basically two flavors: direct GPIO pin manipualtion through a userland .so based driver, and GPIO wiggling by a driver which loads and runs PRU code May 27 06:55:43 hmm. ok. thank you ka6sox. May 27 06:55:48 those need to be coordinated May 27 06:56:04 Littledog_, after 5.20 you should be able to use the normal opkg upgrade May 27 06:56:36 then there's random adc and spi stuff, but thats secondary atm May 27 06:56:47 till it blows up May 27 06:57:23 mhaberler, if you are using the PRUs then why the Xenomai too? May 27 06:57:34 it isnt either-or May 27 06:57:36 mhaberler, why not have an API to have the PRU code to do the direct GPIO? May 27 06:57:47 the PRU can access the GPIO register May 27 06:57:51 *registers May 27 06:57:52 panto,+1 May 27 06:58:18 Pins cannot serve 2 masters. May 27 06:58:21 because there's no point in doing so in the extra indirection step - NB the PRU can access only a subset to star with May 27 06:58:30 err, no May 27 06:58:32 well sure, thats what the coordination is about May 27 06:58:49 the PRU can access the 'fast' GPI/GPOs May 27 06:58:59 to avoid exactly that by checking for config errors May 27 06:59:01 but it can also access the normal GPIOs via the master port May 27 06:59:02 and the slow ones...via L3 May 27 06:59:44 slow is still 25mhz May 27 06:59:48 that I know, but it does not get you around coordination if different pins are driven by different code segments May 27 07:00:09 my point is that sure, you can do it via user-space May 27 07:01:00 if you already have your application structured that way, well, it's painful to go to a different method May 27 07:01:27 that is a fixed boundary condition, and nothing reasonably easy I can do about it May 27 07:01:28 just don't give that access to the eMMC pins if you are using that for your rootfs. May 27 07:01:45 well that is one of the reasons for coordination, yes... May 27 07:01:51 well, it will work - for now May 27 07:01:57 but there be dragons May 27 07:02:07 right, till somethign changes and the whole house of cards comes down. May 27 07:02:43 if you control ALL the conditions then you are safe..if someone can change *anything* you are in trouble. May 27 07:03:12 life is dangerous in general.. May 27 07:03:27 as long as you understand the risks, go for it May 27 07:03:50 there are 2 pins (4 balls) that are very scary on a BB* May 27 07:04:05 ugh, that reminds me... May 27 07:04:12 how stable do you guys rate the whole cape/capemanager idea? it is a bit fixated on a certain hardware concept; basically what I am shooting for is a soft-cape capability May 27 07:04:43 mhaberler, what would that look like? May 27 07:04:46 soft-cape translates into runtime pinset definition, not eeprom/dts edit time May 27 07:04:56 just NO May 27 07:05:00 please NO May 27 07:05:10 pins can't serve 2 masters. May 27 07:05:17 and who said that? May 27 07:05:27 dtbo May 27 07:05:30 thats what they are for May 27 07:05:49 load em manually with capemanager May 27 07:06:16 maybe I didnt explain it properly, but that is exactly what I am planning to do - use the dts/dtbo/capemanager vehicle to assure separation May 27 07:06:35 panto, does unload work? May 27 07:06:42 yes it worked for me May 27 07:06:44 unload works May 27 07:06:44 ( I haven't tried admittedly) May 27 07:06:54 if you use sane drivers May 27 07:06:57 echo -$SLOTNUMBER >$SLOTS May 27 07:07:08 if you use any of the hwmod OMAP drivers it blows up May 27 07:07:25 so the DRM driver unloading would blow up? May 27 07:07:27 cause no-one has ever tried unloading an OMAP driver May 27 07:07:40 it's not a problem of the driver May 27 07:07:50 it's a problem of the hwmod OMAP stuff May 27 07:08:08 we'll see what goes on with 3.10/3.11 and if it was fixed May 27 07:08:10 joel_, thinks that is not likely to be changed. May 27 07:08:20 there are discussion about killing hwmod completely May 27 07:08:23 *discussions May 27 07:08:57 all this violence May 27 07:08:59 killing May 27 07:09:11 av500, sorry...happens. May 27 07:09:15 this is why I asked about the expected stability of the capemanager idea.. if anything breaks my scheme, its changes there May 27 07:09:56 soft-capes is an Idea I'd like to explore...as people are asking for a 1W on a particular pin that is available. May 27 07:10:09 wut? 1W? May 27 07:10:18 1-Wire May 27 07:10:24 still 1W? May 27 07:10:25 sorry W1 May 27 07:10:29 ah May 27 07:10:32 OK :) May 27 07:10:32 ? May 27 07:10:43 well, yeah - 1 wire works May 27 07:10:48 the weather cape uses it May 27 07:11:03 but the guy wants to use a *different* pin May 27 07:11:18 so currently thats a PITA May 27 07:11:45 I think the concept needs firming up a bit, so everybody is on the same page; the way I view it - it is a set of pins/pinmux settings/possibly other resources tied to an entity, where 'entity' does not necessarily translate into 'kernel driver' May 27 07:11:49 Ideally I'd like to create a dtbo that calls the w1 driver and attaches it to the proper pin wiht th right mux May 27 07:11:58 amn May 27 07:11:59 amen May 27 07:12:21 mhaberler, I will try to find some time writing about what the capemgr does, and how DT works, and all that stuff May 27 07:12:42 that'd be most helpful; did you write the kernel part? May 27 07:13:21 yes May 27 07:14:03 btw if anybody needs it, I have a Xenomai kernel based on 3.8.13-bone19 running fine May 27 07:14:21 mhaberler, sure May 27 07:14:42 if you have a patchset, put it someplace where either me, or koen can take a look May 27 07:15:17 usually we don't have a problem adding patches to the repo (but normally we don't apply them until we've test them) May 27 07:15:23 It will wind up in the next Xenomai release; the patchset isnt mine but it will go its path May 27 07:15:43 cool May 27 07:22:08 pardon me for the clueless question, but I'll try anyway: is there an API a certain kernel driver can check against what the .dtbo describes? (I would need the userland version of that API. No you dont have to write it today ;) May 27 07:22:37 err, what do you mean? May 27 07:23:05 the .dtbo describes a pinset and muxing, and sets up the latter, thats how I understand it May 27 07:23:27 more than that May 27 07:23:51 how would the driver figure what was described in the .dtbo? May 27 07:24:12 becuase the driver is *configured* in the dtbo May 27 07:24:13 which driver? May 27 07:24:33 the whole point of the capemgr is to not have to modify the driver at all May 27 07:24:33 (depending on which it is) May 27 07:24:39 that's the point; the scheme is married to a kernel driver concept May 27 07:24:49 mhaberler, no May 27 07:25:08 you can modify the running DT without causing any driver to load May 27 07:25:27 can you refer me to an API for that? May 27 07:25:51 I still don't understand what you want to do May 27 07:25:56 you have to explain it to me first May 27 07:26:37 DT is a hardware description May 27 07:26:43 linux can choose to load it May 27 07:26:47 u-boot can load it May 27 07:26:53 minix could load it May 27 07:26:55 etc May 27 07:26:57 well as outlined, my requirement is to separate userland entities to keep them from trampling on each others pin assignments/muxing; it would not involve any kernel drivers May 27 07:27:18 that leads to the question how a userland entity can inspect what is in a .dtbo May 27 07:27:21 you can always parse the /proc/device-tree May 27 07:27:29 directory, it's user-readable May 27 07:27:51 what are you grumpys up to May 27 07:28:10 mrpackethead, class is in session...and we are listening... May 27 07:28:26 /proc/device-tree is a representation of the kernel-loaded DT? May 27 07:28:40 guess we better figured out some interesting projects for those FPGA May 27 07:28:55 mhaberler, yes May 27 07:28:57 as the name would suggest... May 27 07:29:06 bingo, that is what I was looking for May 27 07:29:15 very well May 27 07:29:16 note, it's properties are binaries May 27 07:29:27 and there's no type information May 27 07:29:39 so be careful how you read it May 27 07:29:53 (not that you could break something, but, be careful) May 27 07:30:04 also, there are talks about moving it to /sys May 27 07:30:16 isn't proc RO May 27 07:30:21 yes May 27 07:30:52 which part of the kernel exports that, capemanager? May 27 07:31:17 no, it's core DT May 27 07:31:24 ah May 27 07:31:29 or OF, depending on the phase of the moon May 27 07:32:19 'OF' ? May 27 07:33:06 I think that means OpenFirmware May 27 07:33:44 anyway, will read up on it - thanks! May 27 08:18:24 HI all, i am using AM3352 , spl blocked on writel(0x00000008, &gpmc_cfg->sysconfig); May 27 08:18:48 Does anyone know why this happen? May 27 08:19:14 The board can't boot now May 27 08:19:40 hi, I'm having big problems with BeagleBone Black boards....since yesterday, I was using Angstrom, updates the packages now they are both bricks May 27 08:20:13 I've tried creating an image on SD card, but for some reason Windows 7 isn't recognising my SD card, Mac OSX sees card ok. May 27 08:20:47 Sy_: just write the latest image from beagleboard.org to your card May 27 08:20:53 Sy_, have you tried rewriting the sd card with the angstrom eMMC image? May 27 08:21:09 on the mac you can just unzip the archive and dd the image onto the disk May 27 08:21:11 or card May 27 08:21:14 trying....but so far I can't get the image written to the SD card May 27 08:21:24 what goes wrong? May 27 08:21:25 sorry, how ? May 27 08:23:33 what have you accomplished so far? May 27 08:23:40 did you download the image? May 27 08:23:44 uncompress it? May 27 08:25:53 I have the image, img file in a folder May 27 08:26:15 I have the SD-card in a mac book pro running osx lion May 27 08:26:41 ok, then you need to find out the device that the card corrsponds to May 27 08:26:44 diskutil list May 27 08:26:52 not sure how I get the BBB-eMMC-flasher-2013.05.20.img onto sd card May 27 08:27:05 that gives you a list of the mounted/active devices May 27 08:27:27 identify the device name of your card. Something like /dev/diskN, where N is a numher May 27 08:27:31 *number even May 27 08:27:43 done May 27 08:27:45 my bootloader-spl blocked in this:writel(0x00000008, &gpmc_cfg->sysconfig); May 27 08:27:53 then unmount the device, using "diskutil unmountDisk /dev/diskN" May 27 08:27:55 Any idea? May 27 08:28:26 blocked? May 27 08:28:46 Unmount of all volumes on disk1 was successful May 27 08:29:04 yes May 27 08:29:09 ok, then you can start transferring May 27 08:29:15 can't go ahead May 27 08:29:21 how? May 27 08:29:47 "sudo dd if=/path/to/imagefile.img of=/dev/diskN bs=1m" May 27 08:29:52 that will take a while May 27 08:30:25 when it has finished you can eject the disk, using diskutil eject /dev/diskN May 27 08:31:31 put in into you BBB (powered down) with an external PSU and no USB connection. Hold the boot button (the one near the larger USB port) and turn the BB on May 27 08:31:44 it will then boot from the SD card May 27 08:32:26 thank you, waiting for dd to complete May 27 08:32:32 if you have downloaded the eMMC flasher image it will take about 45 minutes to flash the internal memory. During that time the leds will blink. Wait until all 4 are constantly lit, then power the device down and remove the sd card May 27 08:33:32 how long should it take to transfer the image to the sd card ? May 27 08:33:55 that depends on a few unknown factors, like card speed May 27 08:34:05 but in general somewhere between 10 and 60 minutes May 27 08:34:08 approx ? May 27 08:35:27 PaulePanter: sure, saw it just now May 27 08:36:43 still hasn't come back yet May 27 08:36:50 janne_: Do you also have just the BeagleBone? May 27 08:36:52 still performing dd May 27 08:37:04 ka6sox-away: thinks not likely to change? hwmod is shrinking and the future is to move out of mach-omap2 as much as possible May 27 08:37:05 janne_: … and not BeagleBone Black? May 27 08:37:52 I have no beaglebone white May 27 08:38:04 ka6sox-away: too much churn on mach-omap, more hwmod is the last thing we need :) May 27 08:38:27 bbt, gn May 27 08:39:12 janne_: Thanks again. I talked to the Googlers and as they are going to head home tomorrow, it is not needed anymore. Sorry for the noise. May 27 08:39:12 Sy_, just be patiented. It can take another 20 minutes or longer May 27 08:39:17 don't interrupt it May 27 08:40:17 They asked for code review of http://review.coreboot.org/#/c/3279/ and testing though. May 27 08:40:47 ok, is there anyway to determine the status of the operation? May 27 08:42:58 mranostay: meeting people in small amounts? one arm, one leg at the time? May 27 08:46:17 PaulePanter: ok, no problem May 27 08:48:36 Has anybody ever run tests on how quick the GPIO of the beaglebone black is? May 27 08:48:58 is you use the PRU, up to 200MHZ May 27 08:49:33 And if you don't? May 27 08:50:07 potentially slower May 27 08:50:15 much much slower May 27 08:50:40 Yeah, I figured as much considering my experiences with ARM processors dm8tbr. May 27 08:50:43 Hence why I inquire about it. May 27 08:51:20 I need something capable of pulling data at a rate of 60 MSa/s from an ADC for short bursts. May 27 08:51:41 what interface? May 27 08:51:54 i guess it isnt i2c anymore May 27 08:52:00 Nah, parallel lines May 27 08:52:04 Hi all. As my Bone was booting I accidentally removed the SD card (well, I picked up the board and pushed in the card, thus spring releasing it). I then powered it off, and on again 10 seconds later. Now, it's not booting. May 27 08:52:14 use fpga, do memory map of data May 27 08:52:23 still hasn't come back May 27 08:52:32 waiting on dd to complete May 27 08:52:36 I have Ubuntu 12.10 on it. And when I connect to the serial console (which I haven't done before) I see the following: http://pastebin.com/raw.php?i=xhV531JM May 27 08:53:51 narcos: i would guess that it's fsck'ing May 27 08:54:22 I would like to get mysql server running on BBB, has anyone got this working? May 27 08:54:27 with Angstrom? May 27 08:54:38 Sy_: 1) install myslq server May 27 08:54:45 Sy_: 2) configure mysql server May 27 08:54:50 Sy_: 3) ... May 27 08:54:55 Sy_: 4) profit May 27 08:54:59 KotH, well that introduces the problem of transfering data from the FPGA to the wireless interface >_< May 27 08:55:08 I tried (and failed) May 27 08:55:41 bart416: well.. you need to convert the data stream into something the AM33359 can easily handle. parallel interfaces do not fall into this category May 27 08:55:43 @kotH, I tried this yesterday before the problems, whilst mysql did install using opkg mysql5, the service wouldn't run May 27 08:55:44 Guys, I have this USB audio interface that somehow doesn't want to work with BBB, what do I do? I'm trying to use it via libusb, and changing the alternative setting on an interface is probably the first thing that fails. Any further steps to try? (tried usbmon, but I think I'm only seeing a control packet setting altsetting going out, and EPROTO reported as status of the "response") May 27 08:55:53 KotH, is it better at differential input? May 27 08:55:57 bart416: and since when are adc connected wireless? May 27 08:56:11 KotH: Ah ok. I'd just gotten a new PSU from a friend to try (after last night's debacle) May 27 08:56:30 Since the data it's sampling would take half a minute to process on an embedded device. May 27 08:56:42 KotH: parallel interface on GPMC May 27 08:56:49 bart416: what are you trying to acheive? May 27 08:57:20 I'm building a radar for a drone/rc ship. May 27 08:57:58 av500: exactly. that's why i proposed the fpga solution May 27 08:58:19 Regular cameras are too dodgy for this. But FMCW with good resolution is troublesome if you don't do some serious oversampling I've noticed. May 27 08:58:45 Koth: to convert the $ARBITRARY_PARALLEL_INTERFACE to GPMC and then talk GPMC to BBB? May 27 08:58:57 GPMC is parallel already May 27 08:59:31 16 bit or so May 27 08:59:44 av500: but it may have a different protocol/number of bits/whatever than bart416's ADC I suppose? May 27 08:59:52 so? May 27 08:59:55 kfoltman, I'll just switch ADC. May 27 08:59:55 Sy_: you have a mysql problem then, not a beagle problem May 27 08:59:57 have a look, compare May 27 08:59:57 That's not a big problem. May 27 08:59:58 etc.. May 27 09:00:13 I guess all the ADC needs is a /RD signal May 27 09:00:17 bart416: go fpga, it's probably the simplest solution May 27 09:00:22 I trsut GPMC can create that May 27 09:00:34 Guess I could have the FPGA buffer the data and then read it out with whatever and just transfer it. May 27 09:00:37 bart416: using an fpga you can also preprocess and reduce the amount of data to be transfered May 27 09:00:50 Well yes, I could do the FFT on the FPGA already; May 27 09:01:03 av500: adc interfaces do not match memory interfaces well May 27 09:01:12 its not a memory interface May 27 09:01:14 its GP May 27 09:01:17 General Purpose May 27 09:01:43 then i misread the docu ^^' May 27 09:01:50 bart416: what av500 says! May 27 09:01:56 at least you read it :) May 27 09:02:03 or made yourself sound like you did May 27 09:02:05 sneaky May 27 09:02:19 The mySQL package is the package thats available via opkg list, I've set-up on many platforms, why would it be a mySQL issue? May 27 09:02:26 .o0(damn, av500 is onto me!) May 27 09:03:28 av500, you'd expect the GPIO speed to be in the datasheet as well :P May 27 09:03:45 no May 27 09:03:55 thats a hard problem :) May 27 09:04:09 Well yes, but at least a general idea of it. May 27 09:04:33 Doesn't have to be good, a rough estimate would be nice. May 27 09:04:53 not 60MHz May 27 09:05:00 unless you use the PRU May 27 09:05:27 no chip manufacturer will put an estimate into their datasheet...because they would be held reliable if someone cannot acheive that "spec" May 27 09:06:10 Or you could pull a Maxim and put notices on it that you don't ensure the part will achieve that speed >_> May 27 09:06:35 no, Maxim will not even ensure the part exists May 27 09:07:02 bart416: listen to av500, for he is knowledgable and wise May 27 09:07:04 Never had that, did have them send me a totally different chip that sort of did the same thing once. May 27 09:07:19 Anyway, the FPGA it will be. Don't feel like messing with that GPMC interface by the first looks of it and the FPGA can do the FFT quickly. May 27 09:07:47 If the Bone doesn't have a MicroSD in it, will it boot in any way? May 27 09:07:49 .o0(fft's used to be the holy grail of VLSI) May 27 09:08:07 narcos: emmc May 27 09:08:14 if there is something bootable in there May 27 09:08:43 av500: I don't think I'd have modified that. And I'd see output via a serial connection? May 27 09:08:57 you would May 27 09:09:04 Only problem with FFTs on FPGAs is that you have to be a bit careful with multiplier assignments. May 27 09:09:08 if the code has serial output May 27 09:09:18 bart416: how would you talk to the fpga? May 27 09:09:21 If you don't you'll quickly run out of logic blocks. May 27 09:09:30 Well the FPGA can buffer the data in its dual port ram. May 27 09:09:39 Then I can read it out at a lower speed. May 27 09:09:53 or at least a higher latency ;) May 27 09:10:29 I'm looking at one update every 10 seconds kfoltman. Latency is the least of my worries. May 27 09:10:41 That 10 GHz PLL on the other hand... May 27 09:11:26 10GHz is easy, these days May 27 09:11:54 Mhhh, sure. May 27 09:11:56 av500: Would the default baud be 115200? May 27 09:12:04 narcos: I guess so May 27 09:12:05 But that doesn't account for the crappy quality of Chinese PCBs. May 27 09:12:12 Hm, not seeing anything. May 27 09:12:21 then maybe there is nothing May 27 09:12:36 Cooould be. Damn. May 27 09:13:17 The problem with 10 GHz is actually how to verify if it's working without a spectrum analyser that goes up that high. May 27 09:13:32 see if your food gets warm May 27 09:13:34 easy May 27 09:13:39 bart416: bandpass filter, decimate, analyze? May 27 09:13:59 Well yes, that's what I thought as well. May 27 09:14:12 But that gives horrible frequency resolution. May 27 09:15:21 (the "decimate" part might be the hard part at 10 GHz though?) May 27 09:15:31 Down mixing isn't really that difficult. May 27 09:15:37 10GHz? just use a LNB May 27 09:15:49 off the shelve part for 10EUR May 27 09:15:58 ofc not super high quality... May 27 09:16:09 Ideally you'd use a Gunnplexer May 27 09:16:11 mixes down nicely to around 1GHz May 27 09:16:32 * av500 would use a multipretzler May 27 09:16:39 that stuff is easy enough to source and usually not thaaat expensive May 27 09:16:52 MikroSD card now in beaglebone, boot switch held in whilst powering up, LED's flickering, will leave and hope for the best May 27 09:16:53 But yeah, still no spectrum analyser. May 27 09:17:07 Sy_: hope dies last May 27 09:17:07 I have to bring it down into the range of a fairly cheap DSO and then use the FFT on that one. May 27 09:17:41 what do u mean av500? May 27 09:18:25 Don't need to explain that DSOs aren't made for this sort of thing. May 27 09:18:30 bart416: what do you want to measure with the spectrum analyser? May 27 09:18:45 bart416: there are DSOs that go up to 10GHz May 27 09:18:46 The output of the VCO of the PLL. May 27 09:18:53 bart416: what of it? May 27 09:18:54 Well sure, but do you have one at home? May 27 09:19:10 Well, if you build a VCO it tends to be important that it actually works. May 27 09:19:10 its frequency? its wander? its spectrum? May 27 09:19:16 Spectrum obviously May 27 09:19:26 well..then the lnb aproach will do May 27 09:19:36 it mixes down the whole spectrum, as you need it May 27 09:20:02 I want to avoid this happening again, whats the advice regarding patching? May 27 09:20:37 If I use a LNB I could just as well use a Gunnplexer. May 27 09:21:03 The advantage being that the latter works both ways. May 27 09:21:22 KotH: Hm, I took the microsd out, and fsck'd it from my laptop, sems all fine. May 27 09:21:40 Sy_: sorry? May 27 09:22:45 narcos: still same effect in your bbb? May 27 09:22:59 KotH: Trying now May 27 09:23:08 If this works and I get the BBB back, I don't want to end up in this state again, all I did before was opkg update....but if this is unreliable and can lead t a brick then hw can I avoid it and yet still be up to date? May 27 09:23:17 KotH: When booting over serial, should I have just the serial plugged in, or serial + 5V ? May 27 09:23:49 Sy_: don't run opkg update for now May 27 09:24:12 narcos: booting over serial? ie loading the image over serial? i dont know May 27 09:24:22 ok, seems like a pretty serious problem, with potentially lots of duff devices May 27 09:24:24 narcos: i dont own a bbb, never worked with it May 27 09:24:37 KotH: Ah ok, I think I just use the serial/USB cable. May 27 09:24:52 narcos: if you just need a serial console: connect rx/tx and gnd May 27 09:25:05 narcos: dont forget to set the right baud rate :) May 27 09:25:16 and 3.3V not 5V May 27 09:25:24 well, a 3.3V device May 27 09:25:40 Hm, before I take out the microsd from my laptop - I had to do a fdisk -n, as the file system mounted read only. Maybe I should try get it rw and do an fsck again? I'm not sure why it would be mounting ro? May 27 09:25:59 shouldn't you umount before fsck anyway? May 27 09:26:13 fsck on an already-mounted filesystem sounds like a bad idea to me? May 27 09:26:24 That's true, I did unmount the fs - as you always should May 27 09:26:30 Sy_: frequently reinstalling and experimenting is part of embedded devices May 27 09:26:45 Sy_: no duff devices May 27 09:26:46 Strange that I'm getting this message? Unless the slider on the SD adapter is faulty May 27 09:26:50 you cannot brick it May 27 09:26:55 you can always reinstall a new image May 27 09:27:35 narcos: I sometimes get the read only behaviour from SD cards randomly, or depending on which USB port in a hub the reader is plugged in (?! yes) May 27 09:27:50 kfoltman: Weird. I'll go try on another machine. May 27 09:29:07 I have two BBB, if I get one of them up and running the way I want it, is there a simply way to transfer the image of one to another? May 27 09:30:45 Sy_: one idea would be to run the OS from an SD card and ensure it doesn't use eMMC, then copy it over ethernet to another machine, which also runs an OS that doesn't need to access the eMMC, and make it copy the data it received via ethernet to the eMMC May 27 09:30:50 selam TR_KaanErkol May 27 09:31:18 thank you will investigate once I get back online :) May 27 09:31:30 Sy_: easy: run both from identical SD cards May 27 09:31:35 Sy_: perhaps netcat/socat could work May 27 09:31:38 and ignore the emmc May 27 09:31:56 av500: good idea, but it's slower, isn't it? May 27 09:32:17 depends May 27 09:32:25 slower to blink the cursor? May 27 09:32:27 to boot? May 27 09:32:28 OTOH you don't need to worry about erase cycles on the eMMC, you just bin the SD card when it's dead May 27 09:32:35 to run a bitcoin mining rig? May 27 09:32:40 av500: to compile a kernel and gcc? ;) May 27 09:32:50 in that case, both are slow May 27 09:32:53 use your PC May 27 09:33:08 av500: to stream 30 channels of sample data in realtime? May 27 09:33:23 define realtime May 27 09:34:19 let's say one channel is about 176-352KB/sec (only octave of downsampling) and the expected latency is <2ms May 27 09:34:44 and what does that have to do with sd card speed? May 27 09:36:30 av500: I mean, the data for playback are played directly (well, with some level of buffering) from the sd card (or the eMMC) May 27 09:37:09 nevermind May 27 09:37:44 s/played/fetched/ May 27 09:38:37 well May 27 09:38:52 I would say that mobile phones play audio and video from sd cards just fine May 27 09:41:44 av500: sure - in this case, I do multi-channel playback (it's a musical instrument basically, each note = new stream or multiple streams, due to layering) so the bandwidth requirements may be higher, and the audio data is uncompressed PCM, so it may or may not come close to the limits of read data rate of the card May 27 09:42:30 [kernel] koenkooi created 3.8-rt (+1 new commit): http://git.io/giBKFg May 27 09:42:30 kernel/3.8-rt aafe3d8 Koen Kooi: 3.8-rt: enable PREEMPT-RT patchset... May 27 09:42:49 it probably depends on the card, its wear-levelling strategies, fragmentation etc., no idea May 27 09:43:04 Yeah, my SD adapter's lock switch is borked. Ran fsck with another one, and reports all fine May 27 09:43:55 kfoltman: digital cameras record and play HD video from sd cards May 27 09:44:10 I think I may be discovering the tty too late, maybe if I write a udev rule to fix it May 27 09:46:51 kfoltman: I would say, the sd speed is not your issue May 27 09:48:55 back May 27 09:49:44 panto: right on time for lunch! May 27 09:50:04 meh, your lunch is way to early for me May 27 09:50:11 lunch at 3, dinner at 9:30 :) May 27 09:50:44 *on summer vacation schedule dinner can be pushed to the 11:00-00:00 time schedule May 27 09:51:35 Sy_, did the procedure work? May 27 09:53:14 The SD card is in the BBB, still doing its thing LED's still blinking May 27 09:54:38 hmm, why the heck is telco power *-* 48V? May 27 09:54:43 as in -48 May 27 09:54:55 panto: ah.. you're still eating breakfast May 27 09:55:07 av500: huh? May 27 09:55:17 Hmm, what would I expect to happen with these udev rules - http://beagleboard.org/static/beaglebone/latest/Drivers/Linux/FTDI/mkudevrule.sh - should I see a /dev/beaglebone-serial instead of a ttyUSBx ? May 27 09:55:18 av500: 48V ok.. but minus?? May 27 09:55:46 av500, because that's the ring signal voltage May 27 09:55:57 http://wiki.answers.com/Q/Why_telecom_power_supply_has_-48V_dc_power_supply May 27 09:56:03 panto: ring signal voltage is 60V AC May 27 09:56:11 The negative voltage on the line was better than positive to prevent electro-chemical reactions from destroying the copper cable quickly, if cables get wet May 27 09:56:12 it's close enough May 27 09:56:18 gee May 27 09:56:27 thats even more ancient cargo than interlaced May 27 09:56:35 it's 100y+ May 27 09:56:39 yep May 27 09:56:46 and still works May 27 09:56:48 and new blade servers have now -48V inputs :) May 27 09:56:57 oh..kay.. May 27 09:57:06 so they dont rot in the rain May 27 09:57:16 av500: huh? May 27 09:57:17 http://www.astrodigital.org/space/stshorse.html May 27 09:57:38 av500, it's because they're no longer PCs, they're infrastructure May 27 09:57:47 KotH: ham radio guys like surplus 48V PSUs May 27 09:57:54 but they dont like the -48 :) May 27 09:57:56 and reliable -48V power supply is a solved problem May 27 09:58:02 right May 27 09:58:56 This looks like its going to work, I'll come back l8r, thank you for your help. May 27 09:59:08 av500> to run a bitcoin mining rig? <-- Wouldn't that be a bit power inefficient :P May 27 09:59:36 bart416: maybe May 27 09:59:36 Does anyone know where I can get a small PSU that would be suitable to power two BBB ? May 27 09:59:43 Sy_: yes May 27 09:59:46 buy a powered USB hub May 27 09:59:50 buy a powered usb hub May 27 09:59:51 5V, 2A May 27 09:59:55 dm8tbr: you lag May 27 09:59:59 * dm8tbr high-fives av500 May 27 10:00:21 if (strcasecmp(av500, dm8tbr) == 0) bingo(); May 27 10:00:23 I have one of those...will dig it out and try May 27 10:00:28 thank you May 27 10:00:48 hehe May 27 10:01:41 theres what are you argumng bout now May 27 10:03:00 av500: i can imagine why hams want telco PSUs... they should have very little noise below 5kHz May 27 10:04:12 KotH, telco stuff == serious business May 27 10:04:22 I just slap a giant ferrite around it and then a bunch of 100 nF capacitors for my RF stuff. May 27 10:04:27 Tends to work pretty well May 27 10:05:12 panto: definitly May 27 10:05:30 panto: and if you want to place any equipment there, there might not be any light on, when it's working May 27 10:05:41 I know May 27 10:05:50 was in the biz for 10 years May 27 10:05:55 poor you May 27 10:05:58 yep May 27 10:06:02 must be a traumatic experience May 27 10:06:07 you have no idea May 27 10:06:13 and i'm glad about that May 27 10:06:18 especially .gr state run telco May 27 10:06:35 *privatized now May 27 10:06:54 well, I didn't work for the telco, I worked for their main supplier May 27 10:07:40 KotH: So if not a Bone, you have a BeagleBoard? Or you just like the company here? :) May 27 10:07:43 i dont want to insult you, but anything state run in .gr sounds like a traumatic experience ;) May 27 10:08:01 narcos: nope May 27 10:08:07 narcos: i've two pandas May 27 10:08:23 ah ok - I haven't tried the panda May 27 10:08:26 narcos: and i got blackmailed into joining this channel May 27 10:08:29 KotH, no, you don't really insult me May 27 10:08:31 * KotH blames koen May 27 10:08:31 heh, OK May 27 10:08:38 if it were up to me I'd fire them all May 27 10:08:54 panto: dont you have a rifle? May 27 10:09:00 panto: i'm quite sure you have enough walls May 27 10:09:20 they outnumber us 100:1 May 27 10:09:30 will need something more efficient May 27 10:09:51 swiss assault rifles?

May 27 10:10:14 no, no need May 27 10:10:20 time May 27 10:10:31 panto: sell the country on the free market, i'm sure the turkish gov will be happy to buy you :) May 27 10:10:54 KotH: no sale May 27 10:10:58 they dont own it May 27 10:10:58 well, no May 27 10:10:59 but then... the current tr gov is... May 27 10:11:12 something one should shot May 27 10:11:13 cause we've been there, we kinda hate it May 27 10:11:15 twice at least May 27 10:11:23 panto: they left nice coffee May 27 10:11:38 true May 27 10:12:06 panto: dont worry, turkey evolved since then. the country is a lot more islamistic. any other religion will not be tollerated because they are morally wrong May 27 10:12:27 and btw, looking at the latest .tr trends and the import/export gap, you're following into our footsteps May 27 10:12:46 all you need is to take on the olympics and it's over May 27 10:13:09 what do you expect from a gov that places more value in wearing headscarfs in schools than solving the economic problems? May 27 10:13:33 the people get, what the people wants May 27 10:13:41 yeah May 27 10:13:47 and then wonder wtf happened May 27 10:14:18 sad thing is, people in .tr had more luxuries during the embargo time in the 80s than they have these days... but people complain a lot less.. May 27 10:14:49 i dont remember seen joe average so poor in .tr as these days :-( May 27 10:14:58 seeing* May 27 10:15:17 fucking "islam is great" goverment May 27 10:15:38 fucking "we have to protect our relgious values against the evil west" people May 27 10:15:57 * panto agrees May 27 10:16:13 another 5years and they will start stoneing girls that wear mini skirts May 27 10:16:35 KotH: "people getting poorer" is a global trend, not just Turkey - it's the same in Ireland, and from what I read, everywhere else May 27 10:16:39 that's the problem with democracy May 27 10:16:41 kfoltman: no it isnt May 27 10:16:44 every dumbass has a vote May 27 10:16:50 KotH: sure, religious nuts don't make things any better :S May 27 10:17:02 panto: that's not the problem May 27 10:17:10 well it is May 27 10:17:10 KotH: 10 years ago my turkish friends were lamenting how progressive Turkey was compared to the dutch turkish community May 27 10:17:16 and I can explain it May 27 10:17:20 KotH: they parents are stuck in the 60s May 27 10:17:51 panto: they fucked up the schoolsystem royaly for the last 30 years. now people have more faith in genesis then in evolution (70% of the people in .tr think that the evolution theory is wrong.. more than in the usa) May 27 10:17:59 since it's easy to pander to dumbasses politicians will do so, not paying attention to 'unpleasantries' like the state budget May 27 10:18:11 KotH: but in Ireland housing/food/energy prices are going up, salaries are mostly stagnant (except for IT), employment is going down, and cuts cuts cuts and new taxes everywhere - maybe it doesn't compare to Turkey, but it's definitely on a downwards trend overall May 27 10:18:14 koen: yeah.. i know that... May 27 10:18:18 just take a loan, put it on the CC, I'll be long gone when the s**t hits the fan May 27 10:18:32 koen: i remember my youth: women walking in the streets in mini skirts.... no headscarfs May 27 10:18:49 koen: today walking around w/o a headscarf seems to be a major offense May 27 10:19:08 KotH: fortunately, Irish church committed institutional suicide and the society is fairly liberal May 27 10:19:10 it's best if you think of the irresponsible behaviour as a mimetic virus May 27 10:19:19 kfoltman: sounds the same what .tr has been trough in the last 20y May 27 10:19:30 if bad behavior is not averted, it tends to spread, cause it's comforting May 27 10:19:34 kfoltman: just that the islamists are gaining every day May 27 10:19:42 until the inevitable breakdown May 27 10:19:57 so May 27 10:20:10 olympic games in turkey in 7 years? May 27 10:20:14 juup May 27 10:20:23 panto: well, you've described Irish banking sector very well ;) May 27 10:20:33 or i start a revolution and line those fucking idiots up on a wall May 27 10:20:33 heh May 27 10:20:44 Back, one BBB now up and running, thank you, question, how to I install ntpd to keep the device synchronised? May 27 10:20:58 KotH, not going to happen anymore; the military is purged isn't it? May 27 10:21:06 KotH: what can I say, sounds well fucked up indeed May 27 10:21:21 oh yeah May 27 10:21:27 snafu's for everyone!

May 27 10:21:50 yes May 27 10:22:04 panto: something like that would have not been possible in the 90s May 27 10:22:15 looks like systematic cleansing of anyone that could pose problems May 27 10:22:25 panto: placing retired generals on trial for something they could have easily done while in service... no way.. May 27 10:22:33 panto: juup May 27 10:22:40 panto: and people are too scared to do anything about it May 27 10:22:41 KotH: I liked the MS Word "evidence" May 27 10:23:05 panto: heck... i wonder what happend to the turkish that fought 4 big nations at the same time, with nothing more than sticks and stones May 27 10:23:11 koen: ? May 27 10:23:17 koen: must have missed that May 27 10:23:31 KotH: well, there's hope in Turkey joining EU, but there might be downsides of course May 27 10:23:34 KotH: allegedly they wrote it all down in 2003 and burned it on a CDROM May 27 10:23:45 kfoltman: as long as merkel stays in power, tr will not join the eu May 27 10:23:49 KotH: only problem is that the .doc says it's written with MS word 2007 May 27 10:23:59 kfoltman: and if this continues, .tr will be in no place to join the eu in a couple of years May 27 10:24:14 it's not as if eu is all roses May 27 10:24:18 KotH: I hope Merkel's days in power are soon over - otherwise she'll bankrupt the whole continent :/ May 27 10:24:24 besides the obvious problems May 27 10:24:24 KotH: the prosecutor argued that "everyone knows ms word will rewrite the document everytime you open it" May 27 10:24:40 it's too burdened down with bureaucracy May 27 10:24:43 on a CDROM May 27 10:25:26 so although the engineers are normally top-notch they have to carry along lots of dead weight May 27 10:25:35 koen: eh.. May 27 10:26:18 koen: well... i've not had any high level technical discussion with anyone in .tr for 20 or so years... May 27 10:26:27 koen: education doesn't count much there anymore May 27 10:26:33 koen: and nowing modern things... May 27 10:26:33 the only good think about the recent .gr burndown was that the problems are getting talked about, and the crazies are easier to spot May 27 10:27:27 yeah May 27 10:28:36 well.. enough ranting for today...lunch time May 27 10:32:36 the problem drived me crazy.... May 27 10:32:53 bootloader does not work for our board May 27 10:34:10 it blocked writel(0x00000008, &gpmc_cfg->sysconfig); May 27 10:34:19 mmmm...have installed tzdata and ntpdate using opkg, have set local time to UTC, but when system is restarted it looses time sync. May 27 10:34:30 I do not know why blocked here... May 27 10:36:37 kelvinji: what does that do? does it switch the system clock to a poorly soldered crystal? May 27 10:37:17 kelvinji: blocked? May 27 10:37:42 kelvinji: or enable some IRQ that doesn't have a valid handler? May 27 10:38:33 panto: thanks for that capemgr stuff...works very nicely May 27 10:38:58 dwery, you must be the only person that said that :) May 27 10:39:04 my cape conflicts with HDMI on the black and capemgr was clever enough to give priority to the cape May 27 10:39:07 everyone else wants to kill me May 27 10:39:20 Sy_: not sure, but maybe it doesn't have a RTC? May 27 10:39:31 that's because you have prioritized my cape and left all the others XD May 27 10:39:41 hehe May 27 10:39:45 kelvinji: stop spamming people in PMs May 27 10:40:00 speaking of which I plan to make a page in elinux explaining the concept May 27 10:40:11 will surely read it! May 27 10:40:16 (on my copious free time) May 27 10:40:34 It doesn't need an RTC, I want to get it to sync. periodically to the internet NTP server...if it does this at regular intervals then thats ok. May 27 10:40:52 Damn, finally got a serial connection in. May 27 10:40:59 panto: are the flags in slots documented womewhere? May 27 10:41:03 I'm trying a cron job May 27 10:41:10 narcos: now you need one out too May 27 10:41:27 1 * * * * /usr/bin/ntpdate -b -s -u pool.ntp.org May 27 10:41:38 just to see if it works, then will change time to 30 mins. May 27 10:41:51 av500: Heh, well, it's going both ways May 27 10:42:03 I'm almost back to where I was last week.... May 27 10:42:05 dwery, err, not really May 27 10:42:10 just curious May 27 10:42:15 dwery, it's just status info May 27 10:42:26 loading, loaded, failed, etc May 27 10:42:27 http://xkcd.com/349/ <- my past few days May 27 10:43:39 panto: I was too lazy to give a look at the code.. did it now, pretty clear May 27 10:44:13 narcos: I think it's par for the course with embedded ;) whole day spent and no progress apart from knowing that certain approaches don't really work, or at least that they were not done correctly May 27 10:44:14 one bad thing about /sysfs is that's a user-facing API May 27 10:44:23 one screw-up and it's stays with you forever May 27 10:44:36 didn't work, doesn't look like cron job is running May 27 10:45:22 panto: yep, I know it very well :( May 27 10:45:41 the mantra was one sysfs per property May 27 10:45:53 I'm not sure if /slots could be that way or not May 27 10:46:08 me neither May 27 10:46:35 panto: you might want to add a status property to the cape directory May 27 10:47:00 hmm May 27 10:47:01 there's lots of stuff to do for the 3.10+ forward port May 27 10:47:04 Sy_: connman May 27 10:47:08 sysfsfs May 27 10:47:19 panto: with text based status "probed", ... May 27 10:47:21 av500, banananana? May 27 10:47:29 an fs using sysfs May 27 10:47:34 as storage May 27 10:48:17 hmm May 27 10:48:19 devmemfs May 27 10:48:26 the more you store, the less you have May 27 10:48:35 Sy_: /usr/lib/connman/test/set-global-timeservers May 27 10:50:50 kfoltman: What makes me sad is I went through it all a month ago, and everything was working fine, and today I wanted to deploy my stuff, and things "stopped working" :P May 27 10:51:04 ok, I've entered "/usr/lib/connman/test/set-global-timeservers pool.ntp.org" May 27 10:51:11 What does that actually do? May 27 10:51:25 hmm, what could "set-global-timeserver" do May 27 10:51:43 I know, I know, pick me, pick me! May 27 10:51:44 Sy_: it tells connman which host(s) to try to sync with May 27 10:51:54 sorry .......http://pastebin.ubuntu.com/5706434/ May 27 10:51:55 I realise how that sounds....but having done it, when does it set the time, having check it hasn't May 27 10:51:55 shhh panto May 27 10:52:12 will it keep the setting after reboot? May 27 10:52:23 if your DHCP server sets an ntp server address connman will use that automagically as well May 27 10:52:39 Right, static IP, let's see if ethernet works again now May 27 10:53:44 Sy_: try and see May 27 10:53:49 It does. I've changed nothing. WTF. May 27 10:54:04 ah well. May 27 10:54:20 does the bbb provide 5V DC or AC ? May 27 10:55:21 Excellent, thank you russell, it works, have reset twice and pulled the power, keeps time after power up. May 27 10:55:47 Moult: if you feed it DC, it provides DC May 27 10:55:52 if you feed it AC, it breaks May 27 10:55:58 but might still provide AC May 27 10:56:25 Does anyone have any links or pointers for getting mysql installed and running on BBB? I installed it yesterday, but it wouldn't run. May 27 10:56:40 define not run May 27 10:57:04 "it stays on the desk where i placed it." May 27 10:57:11 av500: this is from laptop usb May 27 10:57:13 I'll install it again and report the error message May 27 10:57:31 Sy_: no, never give out information just like this May 27 10:57:37 make us work hard to get it :) May 27 10:57:47 Moult: USB is 5V DC May 27 10:58:06 av500: I'm finding weird behavior when controlling some servos. If I run them for say 3 seconds no problem May 27 10:58:20 If I run them for 5 seconds then stop, the bbb dies May 27 10:58:27 Any ideas what could cause that? May 27 10:58:27 Sy_: Wouldn't run, how so? May 27 10:58:46 Sy_: I suspect it's less to do with the BBB, and more to do the the OS May 27 10:58:50 Moult: use a proper power supply May 27 10:59:05 Moult, your bbb dies... it's malnourished May 27 10:59:25 your servos eat your bbb's food May 27 10:59:29 bbb sad May 27 10:59:29 av500: I find that using a power pack doesn't allow me to turn the servo clockwise and anticlockwise May 27 10:59:35 get some soylent May 27 10:59:37 ? May 27 10:59:54 get a more powerfull power pack May 27 11:00:03 av500: but if powered from the bbb, certain pwm periods allow me to. Very odd May 27 11:00:16 indeed May 27 11:00:16 Sy_: I suspect you've been Googling, but the first hit seems to indicate a problem with MySQL and Angstrom - http://arobenko-tech.blogspot.com/2012/09/install-mysql-on-beagleboardbeaglebone.html May 27 11:00:32 ( assuming you're using Angstrom, I'm using Ubuntu 12.10 ) May 27 11:00:41 av500: you reckon it's because I don't have a strong enough power pack? May 27 11:00:59 I have no idea May 27 11:01:09 but power issues can be debugged easily May 27 11:01:12 multimeters May 27 11:01:12 av500: the servo spec says 6v max, I've fed it 6v worth of batteries and no luck there. May 27 11:01:13 scopes May 27 11:01:19 etc.. May 27 11:01:41 Moult: assume we are not standing behind you May 27 11:01:54 so we have no idea what you connected and how May 27 11:02:10 Moult: Do you have a DVM / multimeter? If not, that should be your first purchase for diagnosing all kinds of power problems. 10 quid is ample. May 27 11:02:11 av500: right. May 27 11:02:50 Thats the post I came across yesterday... May 27 11:02:56 Here's the beef. I've got a continuous rotation servo hooked up to a pwm signal pin on the bbb May 27 11:03:09 KotH: So you were right - I have a new PSU, and suddenly things are behaving normally. It's a 2A one - still trying to find a >2A one. May 27 11:03:17 Surprinsingly uncommon in these parts. May 27 11:03:18 If I power it via the bbb, some periods allow me to make it rotate anticlockwise and clockwise May 27 11:03:25 narcos: buy a 7 port hub May 27 11:03:31 they have like 3A PSUs :) May 27 11:03:52 But if I power it using batteries, all periods produce a single direction May 27 11:04:46 av500: no fancy circuit to show May 27 11:04:55 http://www.pollin.de/shop/dt/Nzg5OTQ2OTk- May 27 11:04:59 5V, 3.7A May 27 11:05:04 narcos: ^^^ May 27 11:05:14 http://www.pollin.de/shop/dt/OTg4ODQ2OTk- May 27 11:05:16 5V 3A May 27 11:06:58 wpan0: RX packets:570 errors:0 dropped:358 overruns:0 frame:0 woot!

May 27 11:16:21 mysql has gone the way of the oracle May 27 11:16:51 opkg update May 27 11:17:23 are you sure it won't render my BBB's as bricks? May 27 11:18:10 you mean like in minecraft? May 27 11:18:28 ok, thank you av500, packages are now updated and mysql is now listed May 27 11:18:41 again, you cannot brick it May 27 11:18:52 well, there was a guy that used a brick to brick it May 27 11:19:19 I'm pretty certain a sledge hammer or a few grams of gunpowder would work as well to brick it av500. May 27 11:19:35 sure May 27 11:19:37 go ahead May 27 11:19:42 dont forget to utube it May 27 11:21:30 narcos: i'm always right when i'm right :) May 27 11:24:14 lol.. i get an invitation to participate in a road show "dream jobs in ICT" for students... me who hates doing software ^^' May 27 11:25:01 KotH: you live in small country May 27 11:25:09 you need to fill in for several roles May 27 11:25:36 I assume you also have a bank May 27 11:25:59 of course i do, and a small shop "import export waren aller art" :) May 27 11:26:08 of course May 27 11:26:13 all tr people have that May 27 11:30:16 KotH, well you could give a speech about why outsourcing sucks even more :P May 27 11:30:32 You wouldn't be lying based on the quality of the sort of code you get from India >_> May 27 11:31:49 bart416: quite a few of our customers have their own electronics development May 27 11:32:03 bart416: they still come to us, and are usually quite happe when the project is over :) May 27 11:32:09 bart416: so much for outsourcing sucks ;-) May 27 11:32:23 I was talking about outsourcing to india... May 27 11:32:36 I've seen code that I'm amazed ever even compiled. May 27 11:32:36 outsourcing is out May 27 11:32:43 nearshoring is in May 27 11:33:22 The list of warnings was possibly longer than the number of characters in the file.

May 27 11:41:38 omg May 27 11:42:31 exact steps! May 27 11:42:43 we need to have that blog post taken down!

I have some trouble with my Beaglebone A6; the problem is the CANBus cape is not detected (nothing appears after typing dmesg | grep -i cape, or dmesg | grep -i can) May 27 11:55:02 thanks again...ttfn May 27 11:58:59 KotH: OMG: http://forum.xda-developers.com/showthread.php?t=1200089 May 27 12:00:55 * KotH lols May 27 12:01:10 stupidity prevails!

May 27 12:03:10 no May 27 12:03:23 theres an android app that sets that ntp for you May 27 12:03:31 somebody linked that May 27 12:04:05 I thought 'utterly stoopid' was the definition for 99% of XDA content May 27 12:04:10 well..well.. well... May 27 12:04:35 * KotH doesnt mention that the UMTS network time is usually more accurate than ntp, and more reliable too May 27 12:05:00 but maybe it isnt in india... where GSM network time was known to be off by 5-10min May 27 12:05:31 yeah GSM network time generally seems to suck May 27 12:05:49 it was an after the fact addition to gsm May 27 12:05:58 I'd like a bo for my bone, but encasing my USB peripherals too. Something weather tight. Any suggestions? May 27 12:06:03 I'm currently using a lunch box :P May 27 12:06:24 umts has the good time specs just because the base stations need to by synced to a couple of us, which is usually done using GPS, hence accurate time comes for free May 27 12:06:47 I never understood why I needed to set time and date on my Nokia phones in the past May 27 12:06:53 that seemed so dumb May 27 12:06:59 narcos: use a steal box, solder the lid using hard solder May 27 12:07:11 KotH: steal a box? May 27 12:07:25 av500: steal, steel, where is the difference? :) May 27 12:07:58 did someone mention polish cars? ;) May 27 12:07:59 if you steal steel, none May 27 12:08:01 hard solder, /me assumes you mean removing the soldering iron May 27 12:08:34 narcos: lunch box is fine May 27 12:08:44 or get a peli case May 27 12:08:50 russell--: no, hard solder is hard solder, not to be confused with soft solder which is generally used for electronics May 27 12:08:53 or an otterbox May 27 12:09:06 russell--: hard solder has a meltingpoing >400°C May 27 12:09:12 point* May 27 12:10:00 ah, like brazing May 27 12:11:28 av500, KotH: I'd like it to look professional - clients may see it. May 27 12:11:30 russell--: err.. no it is brazing ^^' May 27 12:11:35 narcos: so May 27 12:11:41 get something professional May 27 12:11:41 and I solder like a monkey May 27 12:12:19 av500: Yeah I've been Googling - thought you guys might know something off hand May 27 12:13:24 narcos: Look for "IP65" in enclosure listings, there are bazillions, eg. http://uk.farnell.com/multicomp/mcrp1285/box-abs-ip65-186x146x75mm/dp/1520421 But with weatherproofing come cooling considerations, so you'll have toi think carefully about that. May 27 12:14:05 narcos: get someone professional May 27 12:14:20 fiola: That looks interesting, thanks May 27 12:14:32 KotH: Are you professional? Can I get you? :) May 27 12:15:52 my experience has been <5W nema enclosures not a problem for heat May 27 12:17:05 "NEMA defines standards for various grades of electrical enclosures" <- interesting May 27 12:18:07 narcos: there's a table of NEMA vs IP codes here -- http://en.wikipedia.org/wiki/IP65 May 27 12:18:29 KotH: time shift offset to compensate for signal travel distance/arrival time is available in GSM too; but these are relative timers - I guess the network time is independent of that May 27 12:18:39 fiola: you mean IP68, IP65 is not watertight May 27 12:18:41 fiola: Great, thanks May 27 12:18:49 narcos: sure, you can hire me May 27 12:19:15 narcos: rates are 220 per hour, CHF for small jobs, EUR for big jobs, kuweit dinars for manamgent problems May 27 12:19:15 http://www.reichelt.de/Open-Frame-Netzteile/ELP-75-5/3//index.html?ACTION=3&GROUPID=4960&ARTICLE=132745 May 27 12:19:18 hmm, 5V, 15A May 27 12:19:22 for my beagle farm May 27 12:19:50 also: http://en.wikipedia.org/wiki/Cable_gland May 27 12:20:06 KotH: ?and Zimbabwe dollars for the LOLs? :) May 27 12:20:19 narcos: no, that would be us dollars May 27 12:20:23 KotH: narcos said weather tight, not submersed. With different requirements, you need different solutions May 27 12:20:26 narcos: and it's lulz May 27 12:20:30 How / where do I add firewall exceptions in Angstrom, in Centos I would edit /etc/sysconfig/iptables May 27 12:20:39 Ah - the Cable_gland - I found something similar for USB May 27 12:20:41 fiola: oh.. misread May 27 12:21:16 fiola: thought it was "water tight" May 27 12:21:48 hmm, 5V 100A May 27 12:21:57 tempting May 27 12:22:01 back May 27 12:22:13 front May 27 12:22:17 panto: how was second breakfast?

May 27 12:22:51 coinville May 27 12:25:12 If you're looking to connect your Linux box to the net with your 3G dongle, sakis3g is pretty neat. May 27 12:26:45 well... May 27 12:27:01 Ah, got a nicer way? May 27 12:27:08 in the days, when av500 was still young, people knew how to configure ppp and wrote their pppconfig by hand May 27 12:27:28 ahh May 27 12:27:42 * narcos shuffles his feet May 27 12:28:03 "sakis3g connect APN=internet" is a pretty neat little command, though. May 27 12:28:24 I sense another .gr person there May 27 12:28:33 Trying to maintain the connection proved trickier, I've wrapped an ugly python script around it to try ensure the connection keeps up. May 27 12:28:34 sakis makes pretty obvious May 27 12:28:42 sake? May 27 12:28:57 close enough May 27 12:29:15 My BBB will need to reliably phone home. May 27 12:29:53 liked an Xbox One? May 27 12:29:56 like* May 27 12:30:45 * narcos doesn't know about the Xbox One May 27 12:30:48 don't give them ideas, next thing each box will come with built in battery and GSM module... May 27 12:31:04 Did they backdoor it? May 27 12:31:49 I notice Apple products are pretty bad too. Each time one connects to a network it sends a cleartext GUID to apple servers. May 27 12:32:02 narcos: same goes for android and google May 27 12:33:30 ah May 27 12:33:54 narcos: and i'm pretty sure that koen installed something in the beagles as well, dialing home is hip! May 27 12:34:25 hehe May 27 12:36:07 he has to pay for the 2nd Ferrari somehow May 27 12:38:00 i dont judge him for that May 27 12:38:03 i would do the same May 27 12:40:15 That's why the BBB leds are so bright and continually flashing, they're phoning home on the blue LED network :P May 27 12:40:57 yep May 27 12:48:06 As long as he doesn't poison the second ferrari with blue LED's I'm fine with it aswell... May 27 13:04:35 Hey guys. May 27 13:05:12 I already have a raspberry pi, but I'm thinking of getting beagle board black for extra power May 27 13:05:32 Was wondering if I need anything extra to use the beagleboard May 27 13:06:52 you need either a computer with a usb port or a power supply May 27 13:08:00 Hi everyone! I'm trying to use my USB serial console on the BBB with no success. after connecting the board I can mount it with no problem but I fail create the ttyUSB device. what am I missing? May 27 13:08:39 I don't think the BBB appears as a serial device over USB May 27 13:09:02 then why the UDEV rules? May 27 13:09:03 panto: Already have the power supply May 27 13:09:06 rymate1234: What comes in the BBB package is enough to get you up and running in minutes if you have a PC. But to progress further, several accessories will help you advance faster. Any of the sites selling the BBB will show you compatible accessories like a power supply, microHDMI cable, and serial cable. May 27 13:09:17 Guser: that is for BBW May 27 13:09:19 not BBB May 27 13:09:56 av500: the BBB comes with a drivers directory on it which holds udev rules files. that is not ment for the BBB? May 27 13:10:02 So I need a microhdmi cable May 27 13:11:27 It's not necessary, but it's handy. A serial cable is even handier if you intend to do anything ambitious. May 27 13:12:44 I don't have anything I can hook a serial cable up to May 27 13:12:44 I happen to use Farnell, but any other supplier will list equivalent accessories -- see the long list below --> http://uk.farnell.com/circuitco/bb-bblk-000/beaglebone-black-cortex-a8-dev/dp/2291620 May 27 13:12:51 I'll try to rephrase my quesion: does anyone know what to do in order to get the serial console working via usb on the BBB? (if possible) May 27 13:15:08 Guser: What OS? May 27 13:15:14 ( on your PC ) May 27 13:15:24 Gentoo May 27 13:15:51 Do you see a ttyUSBx when you plug it in? May 27 13:15:57 ( in your dmesg ) May 27 13:16:02 narcos: nope May 27 13:16:10 anything interesting in dmesg? May 27 13:16:51 I'll pastebin it May 27 13:16:59 Guser: So, I haven't tried with Gentoo, but with Ubuntu I see it. May 27 13:17:29 BBB doesn't have a serial console connection on USB. That's why if you want serial, you need a serial cable to connect to the BBB's 6-pin serial console header. May 27 13:18:30 http://pastebin.com/7YxMiLE7 May 27 13:19:10 fiola: narcos got it working, and the documentation says it should work. May 27 13:19:40 fiola: oh, I thought he was plugin in a usb-ftdi adapter via usb on the BBB May 27 13:20:30 erbo: i am May 27 13:21:49 I'm using Gentoo, with picocom for reading the serial port provided by the recommended FTDI adapter "TTL-232R-3V3". The BBB manual describes it, section 7.5, p.76. May 27 13:22:37 I'm confused, what is connected where? :) May 27 13:22:57 Guser: Did you run the udev scripts already? I wonder if that'd have changed your ttyUSBx to beaglebone-serial May 27 13:23:26 erbo: I think he's expecting serial console to come out of the USB client connector, like it did on BB white. May 27 13:23:37 yup May 27 13:23:40 fiola: I do too :) May 27 13:23:59 narcos: I did run it, I'm not getting ttyUSBx nor beablebone-serial May 27 13:24:29 I'm just trying to get a tty. May 27 13:24:54 Guser: I was getting ttyUSBx, then I ran the udev scripts, and stopped getting either. Not sure what's up with that, but I switched to another VM. May 27 13:26:34 Does anyone have any information on how to set-up firewall rules on a BBB ? May 27 13:27:18 Sy_: i suppose iptables can do the job May 27 13:27:20 Identical to any Linux, using iptables and ip6tables. May 27 13:27:42 thank you, will try May 27 13:31:10 fiola: since the serial-cosnole is my fallback option, do you know how to setup the usb networking on gentoo? (i think I'm missing a driver) May 27 13:32:22 Guser: You Gentoo kernel has to have been compiled with cdc_ether May 27 13:33:23 ? May 27 13:33:25 cdc ether? May 27 13:33:31 there is real ether on the bone May 27 13:33:38 ah usb May 27 13:33:43 never mind then May 27 13:33:47 The kernel option is CONFIG_USB_NET_CDCETHER May 27 13:34:20 While you're at it, enable all the CDC options, they'll come in handy. May 27 13:34:36 (As modules,. naturally) May 27 13:36:03 I don't suppose upstart on Ubuntu on the BBB would behave any differently? I can't get a simple job to register May 27 13:36:06 - http://pastebin.com/7KEJkFra May 27 13:37:31 fiola: Many thanks, I went too look for it myself after your fist comment. appreciate it! May 27 13:37:38 narcos: #ubuntu May 27 13:37:38 *first May 27 13:38:23 has anyone implemented a ws2811 driver using the PRU? May 27 13:38:49 on the BBB May 27 13:38:53 Guser: Welcome. You might also like to check out http://dev.gentoo.org/~armin76/arm/beagleboneblack/install.xml and http://dev.gentoo.org/~armin76/arm/beagleboneblack/install_emmc.xml#expand --- I've not tried yet, still on Angstrom, but it's planned. May 27 13:40:40 av500: I got a bunch of "nafc" in there May 27 13:40:42 Guser, are you getting a ttyACM0? that is how the serial port shows upt for me May 27 13:40:45 Rickta59: wasnt that you? May 27 13:40:49 fiola: I looked at it aswell :) maybe when I'll be done with my current project. looks pretty straightforward I must say May 27 13:41:04 av500: ? May 27 13:41:19 Rickta59: I'm recompiling my kernel atm. I'll try to respond soon May 27 13:41:28 Rickta59: the WS2811 guy May 27 13:41:48 i like the ws2811 .. but i haven't done any coding on the PRU to make it work May 27 13:42:09 i've implemented some code for cortex-m0 raw chips using SPI May 27 13:43:11 if someone has already worked out the details of how to do it on the BBB, i'd rather just use it May 27 13:43:31 it works on my MSP430 May 27 13:43:48 yeah i got some of that going too May 27 13:44:08 not really my work .. just a port to msp430-gcc May 27 13:44:27 port? May 27 13:44:30 The Angstrom iptables command doesn't recognise --dport, how do you specify the port ? May 27 13:44:44 conversion for CCS asm syntax to inline asm May 27 13:44:47 for gcc May 27 13:44:47 is it busybox? May 27 13:44:56 asm? May 27 13:45:02 ah May 27 13:45:07 I just wrote it in C May 27 13:45:13 no, that stuff is all low level bitbangign stuff May 27 13:45:22 or hw spi without an os May 27 13:45:27 yes May 27 13:45:30 I bitbanged it too May 27 13:45:50 heh .. that is my new standard how easy it is to use a chip May 27 13:46:01 .. how long does it take to get a ws2811 led strip going May 27 13:46:07 Sy_: did you list a protocol? May 27 13:46:12 Sy_: --dport needs a -p May 27 13:46:57 is it possible to spew spi data without breaks on the BBB? May 27 13:47:07 at 800k May 27 13:47:16 tcp May 27 13:47:47 I tried this: iptables -A INPUT -i eth0 -p tcp -m --dport 3306 -j ACCEPT May 27 13:47:56 but it doesn't like the argument dport May 27 13:48:37 and without -m? May 27 13:48:54 thats better May 27 13:48:56 ty May 27 13:50:32 Do I need to create an iptables file or is entering this into the command line sufficent, will it remember the setting after reboot ? May 27 13:50:46 Probably time for an iptables upgrade, v1.4.15 is getting a bit old May 27 13:53:43 fiola: Do I need to setup a tun device on my pc to connect to the BBB default network? May 27 13:54:06 Guser, what BBB default network? May 27 13:54:25 panto: the USB adapter @ 192.168.7.2 May 27 13:54:28 ifconfig May 27 13:55:45 Guser: You'd just set the device on your laptop to be in the same range, e.g 192.168.7.1 May 27 13:56:35 narcos: but then I'll disconnect from my local network. I think tun will do the work. May 27 13:56:49 Guser: You should have a new device - something like "ethernet gadget" May 27 13:57:01 Well, that's what I sgot. May 27 13:57:07 *got May 27 13:57:23 i.e. not your ethernet/wifi adapter, but a new interface. May 27 13:59:24 just add an alias May 27 14:00:08 Guser: I didn't set up any interfaces specifically for BBB, the interface just appeared all by itself on plugging in -- very good out of the box experience. But not using that now, migrated to standalone operation. May 27 14:00:29 Right, screw upstart, I'm using rc.local. May 27 14:00:32 Hi! Has anyone testes wl1271 with nuttcp? I get about 12Mbps on am3517 May 27 14:02:01 Don't use ifconfig peeps, use iproute2. ifconfig is old and broken and won't work with IPv6, and ifconfig aliases are just plain wrong. Get used to iproute2, you'll need it, and it's far superior. May 27 14:02:25 * koen is still trying to retrain the muscle memory May 27 14:02:26 fiola, I'm an old guy May 27 14:02:32 I know about iproute2 May 27 14:02:35 what fiola said May 27 14:02:39 but, yes, koen + 1 May 27 14:03:14 +1 May 27 14:03:19 +0.5 May 27 14:03:32 KotH: decide! May 27 14:03:38 which rounding mode? May 27 14:03:45 'ifconfig' gets entered when I think "ip link" May 27 14:03:54 koen: It did take a while, yes. The whole ifconfig/netstat/route thing had become instinctive, so the pain was great. Glad it's behind me now. May 27 14:03:54 fiola: Is there a tutorial on switching from ifconfig to iproute2? May 27 14:04:03 iproute2 is more capable _and_ has more logical syntax May 27 14:04:12 shapr: man ip May 27 14:04:14 that never was a reason May 27 14:04:23 its like Betamax May 27 14:04:31 more porn for ifconfig May 27 14:04:36 yep May 27 14:05:01 av500: my quantumstate will not be measured! May 27 14:05:34 * mru observes KotH May 27 14:07:52 * KotH colapses May 27 14:08:00 * av500 kills a kitten May 27 14:08:30 shapr: iproute2 is more logically laid out, so you don't really need a full tutorial, just a few equivalent commands to replace the old stuff that is currently 2nd nature. eg. "ip addr ls", "ip link ls", "ip route ls" for the usual listings, does what you expect. May 27 14:08:32 * panto kills a kitten using KotH body May 27 14:09:27 lol May 27 14:09:32 ip kitten ls May 27 14:09:33 fiola: you don't need the 'ls' part in those commands May 27 14:09:36 it's the default May 27 14:09:42 kill -KITTEN KotH May 27 14:10:14 Yeah, but it's good for showing the symmetry, because other commands go in the "ls" slot. May 27 14:16:16 I still fail to see a usb network interface. i have the kernel modules installed, but nothing shows up. May 27 14:16:39 dmesg/syslog? May 27 14:17:08 looks exactly the same as before http://pastebin.com/7YxMiLE7 May 27 14:19:24 fiola: any chance I could take a peak at your kernel config? perhaps I can find my mistake with a quick comparison May 27 14:19:25 Guser: do a quick check that it's all enabled with gunzip -c /proc/config.gz | grep CDC May 27 14:19:58 fiola: my kernel does not support that May 27 14:20:31 Heh. Recommend you enable it next time you rebuild, it's handy :P May 27 14:20:46 Just grep your .config May 27 14:21:18 CONFIG_USB_NET_CDCETHER=m May 27 14:21:28 should do the trick May 27 14:21:39 but doesn't :-\ May 27 14:23:37 I have cdc_ether, cdc_acm (prolly unrelated), usbnet and rndis_host modules running. May 27 14:24:00 Don't currently have it connected though, that's just residue from a couple days ago May 27 14:25:14 Lemme ssh into that machine foir you, hang on May 27 14:25:56 * av500 feels that the FTDI should have stayed on the BBB May 27 14:25:59 fiola: thanks May 27 14:26:11 av500: wouldnt have be bad... May 27 14:27:40 Guser: 3 modules seem to be involved, from lsmod | grep rndis May 27 14:27:49 rndis_host 4790 0 May 27 14:27:49 cdc_ether 3504 1 rndis_host May 27 14:27:49 usbnet 14810 2 rndis_host,cdc_ether May 27 14:30:00 fiola: I'm missing the rndis_host May 27 14:30:04 adding now May 27 14:30:28 Don't forget /proc/config.gz :P May 27 14:30:56 lol, thanks! May 27 14:31:25 It's just one of those "superfluous but awesomely handy" features :P May 27 14:32:52 yeah, but I come from the security world and there the less options you have the better, especially those who can give out details about your system May 27 14:33:07 not a good practice for home computing though... May 27 14:37:33 av500, _av500_: hey, its obvious that the bootloader problem I posted about can be solved trivially..I was just stating MMU as one of the options May 27 14:38:22 hello May 27 14:38:51 i have beaglebone with Ã…ngström Distribution May 27 14:39:06 can i change for ubutun? May 27 14:40:32 sure May 27 14:40:39 even ubuntu May 27 14:41:09 joel_: still I dont see why a first stage boot loader should use the MMU to protect itself from its own stupidity May 27 14:41:33 also, k.i.s.s. May 27 14:45:08 A bootloader that uses the MMU sounds vaguely reminiscent of a microkernel. It's not a bad idea, but it's definitely not KISS. And someone could reasonably suggest that you'd still need a dumb loader to load the microkernel, nice recursive argument. :P May 27 14:46:07 av500: yes, ofcourse there are more problems that memory overwrites ;) and MMU helps May 27 14:46:36 some secure bootloaders use MMU to randomize the addresses in a certain mode to make it harder to break May 27 14:46:48 s/that/than/ May 27 14:48:00 fiola: yes I agree with you, also some ROM's do use MMU for more security so its not really a new thing May 27 14:48:20 av500: further the post hardly was about MMU but just in general about the exploit, I think we got carried away :( May 27 14:48:30 All that "secure bootloader" stuff of recent years probably has more to do with vendors wanting to preserve their monopolies rather than actual security. May 27 14:48:33 *wasn't May 27 14:48:35 never happens here :) May 27 14:48:44 fiola: well May 27 14:48:48 it can be secure May 27 14:48:54 as in making sure only your code runs May 27 14:49:02 a full secure boot chain works May 27 14:49:16 as the people that have the original motorola droid May 27 14:49:18 ask May 27 14:49:24 with secure omap3 May 27 14:49:33 write a wrong bootloader -> brick May 27 14:51:20 I guess it depends on one's definition of "works". If their requirement was to brick, then it was satisfied. I don't call that "work" though, I call it "break". May 27 14:52:08 it "works" in the sense to make sure only your SW runs May 27 14:52:28 As I said, monopoly preservation. May 27 14:52:50 Hi guys, first time here. So, I read that the size+addr of the ddr that's shared with the pru is supposed to be found in /sys/class/uio/uio0/maps/map2/ but I ionly have map0 and map1. Any ideas? May 27 14:53:14 fiola: that would imply the producer has a monopoly to preserve May 27 14:53:52 Its not only monopoly, it really depends on the application. Some times in certain devices such as point-of-sale, you'd not want _anyone_ to load untrusted code. May 27 14:54:09 Not referring to market monopolies, but to the monopoly over control of what software is allowed to run. May 27 14:54:54 joel_: Fair enough, but a droid isn't a point of sale terminal :P May 27 14:55:38 fiola: yes I agree, some devices are intentionally made less hacker friendly but otherwise have a real application for it May 27 14:55:39 av500: the original droid had actually a non-verifying bootloader, the international version didn't. the bootloader has probably exploitable bugs but nobody invested enough time to find one May 27 14:55:42 *others May 27 14:59:11 ufrn, that's only a limition of the pruss uio driver May 27 14:59:48 there's lots of outdated information out there May 27 15:00:54 ah, I see May 27 15:05:45 mourning May 27 15:07:55 moin moin May 27 15:08:26 mourning May 27 15:08:55 panto: is there a roadmap for docs? May 27 15:09:05 janne_: stop confusing with facts :) May 27 15:10:01 fiola, I plan to write up something today May 27 15:11:24 Must be hard, because there an infinity of things that could usefully be documented, but one has to cut a thin path through them and focus on what is possible. May 27 15:12:56 don't remind me May 27 15:13:15 :-) May 27 15:13:20 Or perhaps :-( May 27 15:13:23 fiola: a good plan is to write about the things that you are doing yourslef. thats the best way to get the documentation going :) May 27 15:14:51 Guser: Yeah, but that's not the shortest path to reasonably complete product documentation. In fact, that's a recipe for the ultimate in sparseness :P May 27 15:16:10 fiola: true true. but it depends on who is doing the documentation. if it's random people from across the world, I think my way is pretty decent. if its the makers of the device/library then you're correct. May 27 15:16:12 fiola, specifically what documentation are you referring to? May 27 15:17:35 ka6sox: Nothing in particular for me, but it's quite common for people to point out the lack of docs for BB*, and just above, panto said: there's lots of outdated information out there May 27 15:18:31 fiola, we have an excellent wiki platform @ elinux.org that I'm sure if you ask for one, you can get an account there and help out making the doco compleat. May 27 15:19:49 I don't think you can roadmap a wiki :P May 27 15:20:45 of course you camk May 27 15:20:57 getting people to stick to your roadmap... May 27 15:21:03 Hehe May 27 15:21:19 roadmap isn't as important as documenting what *is* first. May 27 15:21:29 * SpeedEvil wrote much of the n900 hardware documentayion, May 27 15:21:45 on the wiki May 27 15:22:56 * m_billybob hisses May 27 15:24:09 identify all the chips/busses on the device, and do a page for each May 27 15:24:10 seems Derek Molloy put a new video out today for the BBW May 27 15:24:34 can I find it by googling bbw video? May 27 15:24:40 FINALLY! ITS WORKING. fiola, thank you so much for all the help... I also needed the CONFIG_USB_G_MULTI with rndis support. May 27 15:24:50 Super :-)) May 27 15:24:57 excellent! May 27 15:27:02 Fortunately Ubuntu and Debian peeps don't have such troubles, because the standard distro kernels have everything and the kitchen sink enabled. But Gentoo users typically do the opposite. However, we can also fix it. :P May 27 15:28:36 Guser, fiola can you guys write this usb_rndis stuff up on the elinux.org wiki please? May 27 15:28:52 if you guys aren't around people have to re-invent the wheel..every time. May 27 15:29:14 it doesnt' have to be pretty...we can get people to help with that...just the Facts :) May 27 15:29:53 Yeah I'll help fill in. It's not fresh in my mind because I did all this configuration back at the time of BB white, but it'll come back. May 27 15:30:26 fiola, if you don't have an account request one and I'm sure we can get you one quick. May 27 15:30:54 * panto tries the usb hotplug fix patch May 27 15:30:55 And anyway, that's how wikis work, it's never complete to start with. May 27 15:31:12 and half the stuff is wrong May 27 15:32:01 KotH, the nature of open source is that only the code is correct May 27 15:32:10 if you're lucky May 27 15:32:10 docs always lag May 27 15:32:14 true May 27 15:32:24 but the code is never more wrong than the docs :) May 27 15:32:33 Code is never correct. The compiler should compile the comments :P May 27 15:32:53 I usually see more errors in the comments than in the code :) May 27 15:33:06 fiola: nothing to compile here then May 27 15:33:12 Haha May 27 15:33:19 It's fast! :P May 27 15:33:22 yes May 27 15:34:59 fiola, mru something is better than having folks twist in the wind and go away searching for answers...the are out there...but spread all over the universe :P May 27 15:35:16 (and a lot of them are wrong) May 27 15:35:19 seems to work May 27 15:35:32 for small values of "seems to work" May 27 15:35:43 always May 27 15:35:54 does anyone know, whether with usb one has to reset the device address to zero on bus reset? May 27 15:36:07 * KotH cannot find it in the std May 27 15:36:13 panto: ah, that usb fix dropped of my radar after I blew it away in a rebase :( May 27 15:36:24 heh May 27 15:36:28 pushing to my tree now May 27 15:39:20 SpeedEvil, you can find it by searching Derek Molloy on youtube ;) May 27 15:40:25 ugh, still fscks up missing removal events May 27 15:40:51 oh well, there's so fscking much changes in musb in the pipeline... May 27 15:40:51 ka6sox: In a cosmic sense, "the answers are out there". The trouble is, nobody has the infinite time to find them and separate the wheat from the chaff **while at the same time trying to learn** --- it may not even be possible because you may not recognized the info that you don't yet know. May 27 15:41:30 fiola, which is why I'm trying to get the best doco from all sources into the elinux.org wiki. May 27 15:41:45 Aye, worthwhile plan. May 27 15:41:46 panto: wait for Linus to get fed up with MUSB churn..... May 27 15:42:01 -ENUKEITFROMORBIT May 27 15:42:18 he will demand a stable binary API and a driver in the DT blod :) May 27 15:42:19 blob May 27 15:43:04 if he wants to lower the churn...he should stop issuing . releases ever 3-10 days :P May 27 15:43:14 s/ever/every/ May 27 15:45:58 felipebalbi: do you know if/when Ravi is ready to post the MUSB/DMA patchset for 3.8+ ? May 27 15:46:06 Rate of change is only going to increase, not decrease, so I think we can expect more multicoloured fireworks from dear Linus :P May 27 15:46:42 "all these different arches give me a headache, I want a multi-arch-platform kernel" May 27 15:46:51 teal and orange! May 27 15:46:52 there is no such concept as a "stable point release" in the kernel... May 27 15:47:21 * ka6sox thinks he will make his blog teal and orange.... May 27 15:47:30 +100 May 27 15:47:43 :D May 27 15:48:49 [kernel] koenkooi pushed 2 new commits to 3.8: http://git.io/6vp7zg May 27 15:48:49 kernel/3.8 fe2b9ed Koen Kooi: 3.8: add support for TPS65217 interupts... May 27 15:48:49 kernel/3.8 35a3aba Koen Kooi: 3.8: add usb hotplug fix... May 27 15:48:52 In the end (but not tomorrow), it'll all lead exactly to where Linus is adamant that he doesn't want to go ... microkernels :P May 27 15:49:23 I doubt it May 27 15:50:15 but yeah, maybe if they go diving with Tannembaum one day... May 27 15:50:30 heh minux for all!!! May 27 15:51:41 It will, for engineering reasons. The kernel growth is unstoppable, and it'll be judged that the only way to keep it maintainable is to split it up. Of course, it won't initially be called the first glimmers of a microkernel approach ... that would never do. May 27 15:52:14 all we need is a stable driver API May 27 15:52:32 and LHQL May 27 15:52:51 fiola, I think we're going the other way, it's the h/w that will be simplified May 27 15:53:12 right May 27 15:53:12 one way to slim things out is to drop outdated platforms/boards May 27 15:53:35 you mean common interfaces like ehci that somehow still need per-vendor drivers? May 27 15:53:44 no, that's USB May 27 15:53:49 or musb May 27 15:53:49 it's insane by definition May 27 15:53:54 Hehe May 27 15:53:56 that need per SoC drivers May 27 15:54:09 You guys really hate USB, huh. ^_^ May 27 15:54:25 it's not hate, it's payback May 27 15:54:26 ahci is like that too May 27 15:54:47 and ac97 and its successor hda May 27 15:55:15 I2S forever May 27 15:55:36 http://en.wikipedia.org/wiki/List_of_unsolved_problems_in_computer_science May 27 15:55:46 hmm, one could add "working musb driver" there... May 27 15:55:54 nah, too hard May 27 15:55:55 av500, +1 May 27 15:56:13 doesn't that fall under the generic usb entry? May 27 15:56:18 there is one, right? May 27 15:57:06 can musb be separated from usb and still survive? May 27 15:57:16 I wish the bone had an RTC clock May 27 15:57:30 narcos: afaik, it does May 27 15:57:38 narcos: there is no battery to back it up though May 27 15:58:09 yep May 27 15:58:29 it's trivial to add an i2c rtc May 27 15:58:33 yep May 27 15:58:37 DS1307 May 27 15:58:42 maybe an RTC cape would make sense May 27 15:58:50 a capelet May 27 15:59:03 ds1307 is usualy 5V only May 27 15:59:04 trivial to add a battery too though right ? May 27 15:59:17 the rtc is on the CPU btw May 27 15:59:39 http://datasheets.maximintegrated.com/en/ds/DS1337-DS1337C.pdf May 27 15:59:41 jacekowski: Ahhh ok May 27 16:00:00 1.8V-5.5V May 27 16:00:07 So, as billybob asked, is it trivial to add a battery? May 27 16:00:20 ka6sox I can write up my findings so far, I can email it to you or pastebin it if you like (it will take some time though) May 27 16:00:22 dont we miss the PMIC battery pins? May 27 16:00:37 narcos, there's no space for it on the board May 27 16:00:46 no idea if you can solder it somewhere May 27 16:01:02 OK May 27 16:01:03 battery backup could be done at least a couple ways though May 27 16:01:42 UPS style or by using the battery pads off the board May 27 16:01:46 ka6sox I think the gentoo wiki will be a more suitable place because most people with other distros will not encounter these problems (as fiola mentioned earlier) May 27 16:01:54 I see there's a battery cape, but it's rather bulky May 27 16:03:32 Guser, others are asking for this on *this* platform (rndis) May 27 16:03:42 sending them off to a Gentoo Wiki doesn't make sense. May 27 16:03:49 Guser: I agree. However, we can still put a generic note on eLinux.org which applies to all distros, just naming the modules that need to run and the kernel CONFIG_ lines. May 27 16:04:41 Guser, fiola Angstrom is a Source Based distro...just like Gentoo...based upon OpenEmbedded... May 27 16:04:46 ka6sox: if others are asking about it then I totaly agree. I'll write some document about it tomorrow. How would you like me to pass it to you? May 27 16:05:01 Anyone know if the Beagle Bone Black is plug compatible to work with the Leopard-Imaging LBCM3M1 camera (3M)? Was digging through specs trying to determine... Haven't found it yet. May 27 16:05:06 ka6sox: other distros are written in hexedit? May 27 16:05:21 Guser, ask for an account on the elinux.org wiki and put it there...we can prettify it later. May 27 16:06:08 the important thing is to get the information where people can find it... May 27 16:06:19 * m_billybob nods May 27 16:06:52 ka6sox: I understand. as long as it gets indexed by google I don't think it matters on which URL it resides. May 27 16:07:05 Bah, elinux.org isn't on IPv6. How retro. :P May 27 16:07:06 ka6sox: where do I ask for an account? May 27 16:07:34 * Guser doesn't ever have ipv6 support on his kernel :| May 27 16:07:56 *even May 27 16:08:04 * m_billybob disables ipv6 on his machines first chance he gets. May 27 16:08:29 I disable IPv4 every chance I get :P May 27 16:08:32 on a server though . . . why i do that doesnt make sense May 27 16:08:32 lol May 27 16:08:57 v6 is a passing fad May 27 16:09:05 fiola, there's no place like 127.0.0.1 May 27 16:09:17 localhost ? May 27 16:09:21 * m_billybob winks May 27 16:09:24 or home.. ;) May 27 16:09:31 I always associate that with localhost, not home May 27 16:09:48 same but it made sense to me May 27 16:09:54 thurgood: +1 May 27 16:10:02 IPv6 has been the official *current* version of IP since last June. IPv4 is the *previous* version, techies should be fleeing it in droves :D May 27 16:10:04 Guser go to the wiki and look at the headline banner May 27 16:10:08 it says how to do it May 27 16:10:15 kk May 27 16:11:49 he issue with ipv6 is soho adoption May 27 16:12:16 Crappy ISPs dragging their heels. May 27 16:12:29 fiola, along the lines of "techies" though, for those who wish to surf anonymously . . . ipv6 kind of ruins that May 27 16:12:30 fiola, conversion cost is not going to be cheap May 27 16:12:39 ... routers that don't support it May 27 16:13:35 thurgood: that used to be the excuse, but it's not any longer. The current generation of commodity routers all support it, both on cable and on *DSL. And the prices are no different. May 27 16:14:04 too bad all consumer level routers are crap May 27 16:14:17 that's why I build my own May 27 16:14:20 not everyone has a current gen router, or wantsto replace their for something they don't understand May 27 16:14:35 its all those lousy little SoCs that don't have enough grunt. May 27 16:14:41 and no memory May 27 16:14:46 ya May 27 16:14:55 mine's a dual core2 with 2GB ram May 27 16:14:59 not enough May 27 16:15:04 enough for me May 27 16:15:06 not enough May 27 16:15:07 anyway. gots to give my holiday and head to work May 27 16:15:10 ffs you got routers with gigabit interfaces and a stupid 16MB of ram May 27 16:15:16 And there is no real "conversion" to be done in the core network, as all the backbone providers have been running IPv6-capable equipment for a decade. Plus, IPv6 isn't a *replacement*, it's just an addition running in parallel, so there's little to be changed. May 27 16:15:30 running a POS VxWorks release May 27 16:15:47 fiola, remember the little thing called memory May 27 16:15:47 if all the unused v4 would be given back, we could run for another decade May 27 16:15:57 those 4:6 6:4 conversions take LOTS of that. May 27 16:16:31 I wonder if a modem cape would make sense May 27 16:16:48 the bone is plenty fast for switching DSL May 27 16:16:50 3g modem May 27 16:16:51 yes May 27 16:16:54 ka6sox: most ISPs replace the home routers periodically anyway, so more memory comes with the territory. But yeah, it is a limitation on old equipment. May 27 16:17:10 no, not 3g, normal landline modem May 27 16:17:29 panto, yes, we can do it... May 27 16:17:30 right May 27 16:17:38 bitbang it on the pru May 27 16:17:38 you could even avoid the stupid management crap they run on routers nowadays May 27 16:17:44 av500, err, no :) May 27 16:17:51 err, yes May 27 16:18:05 ok, depends on what you'll bitbang May 27 16:18:16 anything May 27 16:19:38 Yay! If you're proposing to make a future BB* have two Ethernets and be featured as a communications device, the interest will be huge! The entire WRT community, for starters. May 27 16:20:41 Hell, I'd buy half a dozen just to make a distributed firewall router. May 27 16:20:55 baby steps May 27 16:21:07 why not buy a routerboard that openwrt already supports? May 27 16:21:12 +1 May 27 16:21:17 http://shop.8devices.com/wifi4things/carambola2 Or get that May 27 16:21:29 (only if your CPU use is very limited) May 27 16:21:36 Because those aren't BB? :P May 27 16:21:46 or get several BBBs and hook them together May 27 16:22:00 Quite May 27 16:22:00 make a PRU/GPMS high speed backbone May 27 16:22:00 av500, cause routing is only one of the things I might want to do May 27 16:22:07 lol May 27 16:23:56 The PHYs would have to be gig-e though. In UK and a lot of Europe at least, regular ISPs are already working beyond 100Mbps. May 27 16:25:03 http://www.ikanos.com/products/broadband-dsl/ikanos-velocity/ May 27 16:25:10 for example May 27 16:25:21 too bad they are nazis with their docs May 27 16:27:00 * SpeedEvil sighs. May 27 16:27:19 * SpeedEvil looks at his 2.2Mbit connection. May 27 16:27:29 down? May 27 16:27:48 yes May 27 16:27:52 488k up May 27 16:28:06 that's grim May 27 16:28:28 Next year allegedly the phone network is being modernised. May 27 16:28:57 SpeedEvil, are you urban or rural? May 27 16:29:23 My line has 63dB of attenuation. May 27 16:29:51 long way from the CO May 27 16:29:59 about 6km long. May 27 16:30:37 say, GMII clock is 125MHz isn't it? May 27 16:30:55 could you pump it out from a PRU? May 27 16:31:04 can I program beaglebone black by simulink? May 27 16:31:16 panto, using the serial FIFO's probably May 27 16:31:29 but I'm not sure thats a clock value that is supported May 27 16:31:45 bahman, what are you asking? May 27 16:31:53 can I program beaglebone black by simulink? May 27 16:32:13 restating it doesn't clarify anything. May 27 16:32:54 morning emeb_mac May 27 16:33:09 howdy! May 27 16:33:21 i know ornginal beagleboard can be programed by simulink May 27 16:33:44 bahman, what interface does it use to do this? May 27 16:34:56 Quality of answers is proportional to the quality of questions. May 27 16:35:01 GMII is 125MHz with 8 data lanes May 27 16:35:14 panto, probably not May 27 16:35:23 thats less than 2 cycles May 27 16:35:40 what's max PWM frequency I can get from the beagleboard black May 27 16:35:43 yeah May 27 16:36:15 bahman, probably same as BBW May 27 16:36:29 (or close) May 27 16:36:42 what's that frequency? May 27 16:37:05 LMGTFY May 27 16:37:32 thats going to be in spruh73g.pdf May 27 16:46:33 mru, whats the holiday in the UK today? May 27 16:46:51 Spring Bank Holiday May 27 16:47:04 sounds like a blast May 27 16:48:21 you have banks for springs in the UK ? May 27 16:48:30 impressive May 27 16:49:01 hi May 27 16:49:21 anybody home? May 27 16:49:44 no May 27 16:49:48 I"m on holiday May 27 16:49:54 same here May 27 16:50:24 got some noob questions, if you can stomach a noob today May 27 16:50:53 * _troll_ eats MrMike May 27 16:50:57 * ka6sox takes maalox May 27 16:51:18 ha May 27 16:51:21 nice May 27 16:51:44 Go ahead...we don't bite (much) May 27 16:52:09 and now that the troll has been fed... May 27 16:52:14 awesome. so I want to use a Beaglebone Black for industrial control, digital and analog I/O and of course HMI May 27 16:52:26 what is HMI? May 27 16:52:35 Hughes Medical Institute? May 27 16:52:36 what compiler should use, for one? May 27 16:52:45 you have to really bear with me, I a 100% new May 27 16:52:47 what distro are you using? May 27 16:52:59 haven't even gotten there yet May 27 16:53:18 toolchain is dependent on distribution used. May 27 16:53:36 I guess I would the latest distribution? May 27 16:54:31 ka6sox, you mean not all distros use the linaro toolchain nowadays ? May 27 16:54:41 its just like standards...there are many to choose from... May 27 16:55:15 brb May 27 16:55:37 I see May 27 16:55:40 MrMike, I'm not being snarky...seriously...there are more than a few..and they all use different toolchains. May 27 16:56:04 so I have to pick an appropriate distro for my application, I see May 27 16:56:07 start here: http://www.elinux.org/BeagleBone#BeagleBone_Operating_Systems May 27 16:57:06 ogra_, unfortunately there are a bagzillion of those too... May 27 16:57:09 so the distro s like the op sys? May 27 16:57:13 *is May 27 16:57:15 ka6sox, heh, true May 27 16:57:21 MrMike: exactly May 27 16:57:25 gotcha May 27 16:57:43 well for industrial control, what is a decent one? May 27 16:57:49 MrMike, can you tell us a bit about what you want this to do? May 27 16:57:58 industrial control covers a LOT of waterfront. May 27 16:58:03 ka6sox, well, at least ubuntu, fedora and debian should be close on linaro toolchain versions May 27 16:58:26 (version wise i mean) May 27 16:58:34 err, so i said May 27 16:58:41 ogra_, we *are* talking about embedded space...so YMMV May 27 16:58:44 I will be running a PID loop, firing digital outputs, reading dgital inputs, and reading analog inputs May 27 16:59:11 ka6sox, right, for embedded space neither of these is suited May 27 16:59:13 sounds like a job for a Arduino, MSP May 27 16:59:28 basically doing what many people use PLCs for May 27 16:59:30 or the PRUs in a Bone. May 27 16:59:51 20# Sledgehammer to kill a flea. May 27 17:00:10 but I digress... May 27 17:00:21 yes, its probably able to do that quite well... May 27 17:01:08 so the beagle is overkill for what I am doing? May 27 17:01:35 unless the pid loop is running in the uS region... May 27 17:01:50 hmmm May 27 17:02:50 how fast do the changes happen in the PID loop? May 27 17:03:29 I run a new calc once per second May 27 17:03:55 For low speed stuff - there is no especial reason why BBB isn't usable. It's overkill, but... May 27 17:04:22 As long as it's not very critical. May 27 17:04:25 I mean for $45, I don't feel like I am wasting much money even if it is overkill May 27 17:04:28 Don't use for life-critical stuff May 27 17:04:46 'normal' OSs are very poorly designed for embedded. May 27 17:04:46 why not? May 27 17:05:01 would you trust your life to a $45 gadget? May 27 17:05:23 mru, is reliability a function of price? May 27 17:05:24 You don't want it scanning for new song tracks and that process hitting a bug and using up all memory, killing your control task, for example. May 27 17:05:35 I see May 27 17:05:37 either the design meets engineering requirements or not May 27 17:05:56 panto: sometimes it is May 27 17:05:56 So the first task would generally be to kill absolutely all nonessential services. May 27 17:05:59 MrMike, my big concern is the overhead introduced by the OS to what you want to do. May 27 17:06:09 can't I disable all the extras? May 27 17:06:47 MrMike, the linux kernel is not a "RealTime" kernel...its a "Best Effort Scheduling system" May 27 17:06:58 man I have a lot to learn May 27 17:07:07 I am a mechanical engineer, never took a computer class May 27 17:07:13 mru: more than to a 400 Euro iphone May 27 17:07:15 well one, but that was mainly fortran, LOL May 27 17:07:35 Defiant: neither is designed for that kind of reliability May 27 17:07:39 I used emacs and fortran, you guys can stop laughing now haha May 27 17:07:44 MrMike, that also means you didn't pick up any bad habits May 27 17:07:48 fortran is fine May 27 17:07:51 true May 27 17:08:01 panto, +1 May 27 17:08:02 for what it does it's excellent May 27 17:08:13 does the industrial machine has spinning blade or flames MrMike ? May 27 17:08:22 mru, well, there are hospitals using Win XP machines for patient monitorin in this world May 27 17:08:22 or sharks? May 27 17:08:37 ogra_: and patients have died as a result May 27 17:08:45 MrMike, all I'm saying is that you have a LOT to learn for a relatively simple task... May 27 17:08:51 also, who would trust their life to a hospital? May 27 17:08:54 yeah, minor detail May 27 17:09:31 it's not that life-critical, see what it does is re-al time scan crowds of innocent people looking for recognized terrorists and when it finds one, servo-controls a mini-gun to take him out May 27 17:09:43 excellent May 27 17:09:44 so it's not like a big deal for it to work or anything May 27 17:09:48 MrMike, now if you told me you wanted to display all this in some pretty JS thing and control it then maybe...(over the web) May 27 17:09:59 have you worked for the Bush admin btw? May 27 17:10:03 well, you want at least the targeting mechanism to work reliably May 27 17:10:28 a mini-gun? that is 3d printed i hope May 27 17:10:28 it's for a vacuum dryer May 27 17:10:30 to avoid too big collateral damage ... as that gets you bad press May 27 17:11:11 what do most people use beagles for? May 27 17:11:17 what happens if the control loop fails do you lose a lot of money? May 27 17:11:29 are they mainly learning tools as opposed to industrial controllers? May 27 17:11:51 lots of people see it as a inexpensive network interface for other mcu devices May 27 17:11:55 whenever something fails, it's not real good May 27 17:12:04 mcu? May 27 17:12:11 well if i burn pancakes i don't feel bad May 27 17:12:16 MrMike, there are applications for it in the industrial space...but what you are talking about doing is easier done with other platforms. May 27 17:12:26 cool May 27 17:12:31 (no OS to get in the way) May 27 17:12:37 if i screw up setting a $500 worth of vaccum bagged epoxy i would May 27 17:13:14 so I need to be looking more at like embedded c stuff? May 27 17:13:14 mcu like .. avr/msp430/arm cortex May 27 17:13:17 MrMike, if you want to use the power of the Bone to do display and human interaction then ya, its worth doing. May 27 17:13:32 what Rickta59 said... May 27 17:14:21 otoh you could conceivably develop on the bone May 27 17:14:32 and not need a dev box if you do simple stuff May 27 17:15:06 1 PRU could probably do the whole job. May 27 17:15:36 I snagged one to see if it could replace a desktop for the g/f May 27 17:16:10 and also to check out the pru stuff and display capabilties May 27 17:16:14 did it work Rick May 27 17:16:24 and because it is netwrok enabled May 27 17:16:32 hmm .. i've hit a few snags May 27 17:17:04 i thought a hdmi->vga adpatper would work but it seems after i bought the non-powered one i should have gone for the powered vga-hdmi adapter May 27 17:17:07 so it really sounds like I need a board that is more geared towards industry than towards education and hacking May 27 17:17:49 the hardware itself is a good mix .. but may be overkill May 27 17:18:29 but .. you won't have to add anytthing to it likeyou might with a smaller solution May 27 17:18:37 Rick so no hdmi love for you yet eh ? How are those USB hubs workign otu for you so far ? May 27 17:18:46 hubs are good May 27 17:18:48 thanks for the info guys May 27 17:19:15 all my monitors are > 4 years old none have hdmi May 27 17:19:28 it would just work i think if i had a new monitor May 27 17:19:34 do they have dvi? May 27 17:19:44 ah, i do recall someone saying they got hdmi adapter workign though hmm May 27 17:19:47 the free one i had just had vga May 27 17:20:00 the one i really use as dvi and didn't want to sacrafice it to the beagle May 27 17:20:25 an hdmi -> dvi requires nothing other than signal pin translation? May 27 17:20:57 dont rightly know good question May 27 17:21:15 hdmi and dvi are electrically equivalent May 27 17:21:20 i think i read some place that dvi and hdmi were really the same just with diffent pins May 27 17:21:25 it's a simple pin adaptor May 27 17:21:33 well hdmi has audio too right ? May 27 17:21:39 but yeah May 27 17:21:41 same pins May 27 17:21:52 that's a higher-level thing May 27 17:22:06 you can feed audio into a plain dvi display and it will ignore it May 27 17:22:14 so in theory an hdmi->dvi would work fine? May 27 17:23:15 I've sen one guy talkign about it on the groups i believe he finaly got it workign ? but not sure May 27 17:23:40 in the SRM it shows a DVI connector so I'm assuming that is fine May 27 17:23:59 DVI-D May 27 17:24:09 yeah but apparently and i dont know why exactly some or like many ? monitors dont work with the bbb hdmi May 27 17:25:14 nt ure if its an initial resolution thing or what. May 27 17:27:44 let's ignore the vga pins in DVI-I/A May 27 17:29:43 what does a decent hdmi cable cost now days anyhow ? I've never used hdmi but now has a few hdmi capable systems May 27 17:30:22 $2 May 27 17:30:50 its digital, if it works at all, its fine. May 27 17:31:08 (unless it's to be moved around a lot) May 27 17:31:10 SpeedEvil, and the type I would need would be the celphone like cables, or is it somethign else ? May 27 17:31:26 http://www.adafruit.com/products/1322 like that May 27 17:31:30 just saw one on google quick serc for like $6 May 27 17:31:58 that is on the high end of cost May 27 17:32:05 but i had it in a couple of days May 27 17:32:13 well ive seen some just now that go as high as $40 May 27 17:32:27 those are basically for idiots May 27 17:32:31 probably not micro to normal though May 27 17:32:37 unless they are rugged May 27 17:36:56 * m_billybob is currently trying ot figure out why the screen on his debian dev machnie keep coming on once in a while May 27 17:37:46 headscratcher this, onlyway i use it is through ssh, and its CLI only. May 27 17:38:32 SpeedEvil, thanks :) May 27 17:46:51 so .. i just tried on my tv .. works fine May 27 17:47:12 boots up into a desktop May 27 17:49:10 arm-angstrom-linux-gnueabi/bin/ld: cannot find -lssp May 27 17:54:37 mastiff, if you're doing native building.. did you install sdk-task-native May 27 17:55:17 err task-sdk-native May 27 17:57:12 I did not May 27 17:57:56 i'm trying to compile systemd-204 May 27 17:58:15 in oe or on the board? May 27 18:00:12 on the board, it's a dependency for rtl-sdr May 27 18:00:54 fails during make May 27 18:01:31 with the "cannot find -lssp" error May 27 18:02:07 is there a libssp in the requirements? May 27 18:03:31 how do I check that? ./configure completed after installing other requirements that it complained about May 27 18:05:02 first install task-sdk-native if you're going to do native compilation... I would advise using a cross compiling toolchain instead... but you're free to do it how you want May 27 18:05:04 I don't see libssp in /usr/bin/, and opkg didn't find it either May 27 18:05:37 Ok, can you suggest a link for background reading on that topic. May 27 18:05:53 if that doesn't fix it you can manually install libssp0.. that's probably what it's looking for May 27 18:05:58 i'll go ahead and install task-sdk-native to start with May 27 18:06:01 ok May 27 18:06:49 thanks May 27 18:09:28 task-sdk-native is a fairly large meta-package go grab a coffee :) May 27 18:11:24 rtl-sdr requires systemd-204? May 27 18:11:29 that was releases last week May 27 18:11:47 * koen highly doubts that rtl-sdr depends on such a recent systemd May 27 18:11:52 actually May 27 18:11:59 I doubt that it depends on systemd *at all* May 27 18:12:52 not directly, one of the other dependcies for rtl-sdr May 27 18:18:46 ./configure for rtl-sdr fails with "No package 'libusb-1.0 found" May 27 18:44:31 * KotH yawns May 27 18:47:38 Hello, does anyone know of a package that will enable floating I/P for Angstrom ? May 27 18:47:58 Sy_, what do you mean by that? May 27 18:49:02 Ok, you have two servers configured in multi-master mode, one is the backup for the other, the clients connect to one of them using a floating I/P, the I/P address flips between which ever server is deemed to be the current master May 27 18:49:16 so if one dies the I/P transfers to the other automatically. May 27 18:49:34 There is something called heartbeat for other flavours of linux which does htis. May 27 18:49:36 Sy_: start with writing IP instead of I/P, so people might have a chance to understand you May 27 18:49:48 ok, sorry May 27 18:49:56 Sy_: and see whether there is a heartbeat package for anström, if not, compile one yourself May 27 18:50:05 ansgström May 27 18:50:11 gah... May 27 18:50:11 angst rom. May 27 18:50:18 ignor my spelling May 27 18:50:29 I'll have a look tomorrow, see if I can find the source code to heartbeat May 27 18:50:32 KotH: even more than usual? May 27 18:50:38 yeah.. even more than usual May 27 18:51:01 \o/ May 27 18:51:04 didnt have enough spice and chocolate today May 27 18:51:11 poor you May 27 18:51:13 KotH, send chocolate May 27 18:51:26 ka6sox: nah! i keep that formyself May 27 18:51:40 KotH, hoarder May 27 18:51:43 KotH: spice? Seriously? What spice do you like with chocolate? May 27 18:51:48 which reminds me.. i have to buy chocolate tomorrow May 27 18:52:05 fiola: you are not very literate, are you? May 27 18:52:21 More so than you May 27 18:52:28 fiola: you dont seem to know who LetoThe2nd is May 27 18:52:37 Correct May 27 18:52:46 google for leto the second May 27 18:52:53 then buy the books May 27 18:52:56 then read them all May 27 18:52:57 Knowledge and literacy are two different concepts May 27 18:53:00 4) profit May 27 18:53:41 KotH, went straight to #4? May 27 18:53:44 whoa... May 27 18:53:51 #notexactsteps May 27 18:54:08 #approximatesteps May 27 18:54:37 * KotH needs more atomic clocks May 27 18:55:24 * LetoThe2nd disables KotH's atomic clocks via CONFIG_PM May 27 18:58:08 OK, so Leto Atreides was the 2nd, I didn't recall that. But I happen to have the whole series on the shelf in front of me. Loved the books and the film, hated the series. Got them all. May 27 18:59:10 always found Alia interesting...Scary....but interesting. May 27 18:59:43 most women are May 27 19:00:03 many aunts especially May 27 19:00:09 mru: the rest are just scary :) May 27 19:00:23 indeed May 27 19:02:39 hmhm May 27 19:03:05 hmm.. swiss companies are really expensive: oscilloquartz is selling a crystall oscillator for a bargain price of 25'000 CHF May 27 19:03:38 hrhr May 27 19:04:36 KotH, how do you pronounce CHF (or the spelled out version I really mean) May 27 19:04:39 ? May 27 19:04:50 schwiizer frankä May 27 19:05:58 where CH stands for switzerland and F for "Franken" or "Francs" depending on the language you are using May 27 19:06:12 :) May 27 19:06:27 * ka6sox looks at the current exchange rate... May 27 19:07:02 so about $26,000 USD May 27 19:07:12 I could buy an "atomic" clock for that price :P May 27 19:07:28 a new Rb clock costs about 1-5kUSD May 27 19:07:39 a Cs beam standard, iirc 15-20kUSD May 27 19:08:03 a H maser somewhere in the region of a 100kUSD May 27 19:08:13 but I don't even want to know what a fountian clock costs. May 27 19:08:31 of you go to ebay: Rb for 80USD, Cs from about 5k May 27 19:08:44 you cant buy Cs fountains May 27 19:08:51 you have to build them yourself May 27 19:09:15 but if you go that way, do yourself a favor and build an optical ion clock May 27 19:09:26 <_av500_> GSOC is announced May 27 19:09:41 costs about the same but has a couple orders of magnitude higher stability May 27 19:09:42 "Let the Games Begin"! May 27 19:09:52 * LetoThe2nd will just have his fishspeakers readjust time to his liking. no clocks needed. May 27 19:10:01 _av500_: OMG. May 27 19:10:52 KotH, if I need something that stable I'll just ask. May 27 19:10:57 _av500_: does that mean "nearly as bad as trimester projects" or "way more bad than trimester projects"? ;) May 27 19:11:48 LetoThe2nd, for those of us who are parents...that has a different connotation. May 27 19:12:12 ka6sox: ah yes? May 27 19:12:41 1st trimester: "is this really happening" May 27 19:12:44 * LetoThe2nd fails to see a relation between GSOC and parenthood. May 27 19:12:54 oh May 27 19:12:55 nm May 27 19:13:38 * LetoThe2nd fails to see a relation between GSOC and parenthood and NetworkManager. May 27 19:13:44 afternoon everyone, whats shakin ? May 27 19:13:44 ka6sox: i doubt you will ever need anything more stable than an Rb May 27 19:13:54 ka6sox: and that stuff can easily and cheaply bought on ebay May 27 19:13:55 KotH, I have one. May 27 19:14:03 see... May 27 19:14:08 but it consumes LOTS of power. May 27 19:14:15 10W or so? May 27 19:14:24 ya, something like that May 27 19:14:36 that's normal. most of it goes for heating May 27 19:14:50 the rest goes into the Rb discharge lamp May 27 19:15:01 and a tinsy bit for the frequency multiplier May 27 19:15:32 simpsons episodes over, seeya tomorrow May 27 19:15:38 niters May 27 19:18:13 sleep well May 27 19:18:24 cya May 27 19:20:56 meh, sometimes an ounce of understanding is a dangerous thing :/ May 27 19:21:18 half knowledge is always dangerouse May 27 19:21:24 exactly May 27 19:21:25 that's why i am so dangerouse May 27 19:21:55 dangermouse? May 27 19:22:08 people still remember that? :) May 27 19:22:23 dangermoose May 27 19:22:27 * dm8tbr always enjoyed watching it May 27 19:22:32 chocolate moose? May 27 19:22:36 mru: sweedish rip off? :) May 27 19:22:51 swedish chef May 27 19:23:09 troll! May 27 19:24:00 I'm not afraid of a dangermouse...a dangermoose OTOH... May 27 19:24:43 the moose is loose May 27 19:28:20 trying to add frame skipping to our video playback May 27 19:29:49 and running into lots of semaphore issues I hadn't considered initially :/ May 27 19:34:52 bork, bork, bork May 27 19:35:24 bork, bork May 27 19:35:51 pork May 27 19:35:53 * m_billybob prefered the prof and beaker May 27 19:37:29 * KotH preferes lamb May 27 19:37:48 horse isnt bead either though May 27 19:37:52 bad* May 27 19:37:53 ewww May 27 19:38:42 I'll stick with bacon May 27 19:38:42 thurgood, you live in the US chances are slim but possible you've already unwittingly eaten horse May 27 19:38:44 Does someone have gst-dsp running on BBB? May 27 19:38:44 :P May 27 19:39:05 http://hardware.slashdot.org/story/13/05/26/038250/arm-in-supercomputers-get-ready-for-the-change May 27 19:39:32 does bb black have a dsp? May 27 19:39:45 dontthink so May 27 19:39:50 if it does its news to me May 27 19:40:09 yeah, I thought they moved to PRUs May 27 19:40:27 is it "known to men" or "known to man" ? May 27 19:40:40 could be wrong of course May 27 19:41:00 probably man as in mankind May 27 19:41:01 bb black's SoC doesn't have a dsp May 27 19:41:01 i was looking at the procesor diagram last night didnt notice one May 27 19:41:10 but it has neon which is awesome May 27 19:41:15 thurgood: thanks May 27 19:41:17 noticed a rtc on die though when everyone been saying the bbb doesnt have a rtc lol May 27 19:41:28 you don't have a battery for the rtc though May 27 19:41:32 so not much help there May 27 19:41:44 who needs a battery in an always-on system? :) May 27 19:41:57 that could be remidied May 27 19:42:10 put a battery on your design or use a UPS May 27 19:42:21 hmm..the tutorial I have here is for board and bone..doesn't distinguish for dsp.. May 27 19:43:24 OMAPs SoCs have a DSP, but Sitara SoCs generally don't, AFAIK at least May 27 19:43:30 dont really know what would be cheaper, attachign a battery to the bbb on the battery pads, or buying a rtc and putting it on your daughtercard / cape May 27 19:43:47 ntp May 27 19:44:02 so what happens when power goes down May 27 19:44:14 and then comes back up but no internet connection for a long time May 27 19:44:15 don't ask, don't tell ~.~ May 27 19:44:44 the datasheet doesn't mention a DSP..so I guess not May 27 19:44:50 if you're not networked, time is irrelevant May 27 19:45:05 Defiant: no dsp on bone May 27 19:45:12 k May 27 19:45:15 mru not necessarily May 27 19:45:29 mru what if the "board" is controlling somerhing based on time May 27 19:45:38 and it has to be fairly accurate May 27 19:46:34 gps May 27 19:46:57 or just a simple UPS or battery backed solution :) May 27 19:48:39 you will drift a couple of minutes per year May 27 19:49:17 m_billybob: cheap gps will be the best choice May 27 19:49:18 KotH: if you're lucky May 27 19:49:21 m_billybob: it will always be accurate May 27 19:49:52 ntp+battery can work sufficiently May 27 19:50:04 jacekowski, yeah i dont really know which would be better. just thinking in terms of what is already suppied on die May 27 19:50:16 if you're not offline for more than a day or so May 27 19:50:24 m_billybob: on die RTC isn't very accurate May 27 19:50:33 no ? May 27 19:50:39 not in long run May 27 19:50:47 whats the drift on them ? May 27 19:50:56 it's board specific May 27 19:51:02 mru: in a home/office environment, where temp doesnt vary more than 5°C, you can get to that quite eaily after initial frequency offset calibration May 27 19:51:14 although you are talking about couple seconds a day May 27 19:51:30 mru: i know of people wo get to less than 1min/year with pendulum clocks May 27 19:51:37 * ka6sox gets out the wood and charcoal. May 27 19:51:40 jacekowski, well then what you say is probably the best bet then. but yeah like you jus tsaid i can think of a few application that require to the second timing May 27 19:52:01 ka6sox: burning witches again? May 27 19:52:27 Tri-Tip May 27 19:52:34 m_billybob: you can get usb gps module for £16 May 27 19:52:44 pitchfork? May 27 19:52:55 jacekowski: you can even get them for 16usd May 27 19:52:57 probably a module for slightly less May 27 19:52:59 epay is your friend May 27 19:53:17 gps isnt something ive dealt with or looked into much May 27 19:53:34 but yeah like KotH just said lol lots of "cheap" ebay stuff May 27 19:53:55 m_billybob: just plug it in and you get stream of location + time data May 27 19:54:06 m_billybob: ignore location and you get very accurate time source May 27 19:54:15 m_billybob: just be carfull not to get addicted to timing precision May 27 19:54:23 m_billybob: atomic clock type of precision May 27 19:54:23 yeah actually that makes total sense i was not aware gps did time data as well May 27 19:54:25 m_billybob: or you'll end up buying atomic clocks May 27 19:54:30 m_billybob: it has to May 27 19:54:37 m_billybob: and it has to be very accurate May 27 19:54:50 jacekowski: you cannot ignore location if you want to get a precise time with gps May 27 19:55:01 KotH, naw but somethign im workign on requires to the second timing for some stuff May 27 19:55:35 jacekowski: and the precision of single frequency gps after sawtooth correction with a timing receiver is +/-10ns, any atomic clock does better than that May 27 19:56:00 m_billybob: to the second in over a length of a decade? ;) May 27 19:56:13 gps is usually plenty accurate May 27 19:56:23 depends on what you are doing ;) May 27 19:56:34 i've seen that integrated atomic clock May 27 19:56:38 small on chip stuff May 27 19:56:43 CSAC? May 27 19:56:49 KotH, something like to the second every 5, 10 30 whatever minutes. but needs to fire off eaxtly to the second May 27 19:56:53 that's cool stuff! May 27 19:57:04 yeah May 27 19:57:06 m_billybob: pfffft! May 27 19:57:15 m_billybob: any cheap chinese crystall can do that! May 27 19:57:18 http://www.symmetricom.com/products/frequency-references/chip-scale-atomic-clock-csac/ May 27 19:57:23 no challenge there! May 27 19:57:32 jacekowski: i know the CSAC pretty well May 27 19:57:50 how much is one of those? May 27 19:57:55 1500usd May 27 19:58:02 +tax+pp May 27 19:58:10 that's more than gps May 27 19:58:11 single piece May 27 19:59:16 jacekowski: you can have both in one package: http://www.jackson-labs.com/index.php/products/csac :-) May 27 20:02:04 KotH actually though what mru and jacekowski said ther makes perfect sense though a crystal rtc etc all need power to remain accurate. where as any number of scenarios could happen and a gps would be perfectly fine May 27 20:02:51 m_billybob: sure.. but as i said, a second over a couple minutes is no challenge May 27 20:03:19 m_billybob: the bbb should keep that much accuracy with the on board crystal already May 27 20:03:58 KotH yeah im thining worse case scenario though o na remote site. maybe the power goes down for several hours, and when it comes back up the internet may be out still so it has no way of tellig nhow long its been down May 27 20:04:11 so you're forced to have some means of backuppower on the device May 27 20:04:30 m_billybob: NTP is not an option of course? May 27 20:04:32 to ru na rtc or crystal or whatever May 27 20:04:33 m_billybob: a standard crystal is specified to 20ppm, add another 20-50ppm for temp variations and you are at <100ppm. you are talking about 1s in 2000s at most, thats 500ppm May 27 20:05:03 m_billybob: add a battery to the bone, and be done with it May 27 20:05:45 kfoltman anything that works iis an option but again without power and /or internet . . . May 27 20:06:29 well... May 27 20:06:36 use the most simple solution May 27 20:06:42 m_billybob: well, that depends on whether the remote site is a data centre, or, say, a baloon ;) May 27 20:06:46 KotH not discounting anything it does soudn reasonable to me too May 27 20:07:15 balloon, even May 27 20:07:17 use a pit and a pendulum May 27 20:07:33 kfoltman dataventers go down for days sometimes too albiet rarely May 27 20:07:35 hahaha May 27 20:08:39 and a cat May 27 20:08:54 a lolcat? May 27 20:08:55 no solution is complete without a cat May 27 20:09:18 kfoltman sure including lunch ;) May 27 20:09:22 datacenters have more frequent outages, just not catastrophic.. usually May 27 20:09:31 we own 3 GSDs . .. May 27 20:09:38 cats resemble rabbits . .. May 27 20:09:42 they sometimes have backup power generators, too ;) May 27 20:09:52 * m_billybob nods May 27 20:10:40 ok just for worse case scenario elaboration though ive seen a faulty AC unit take out a whole cell phone site ( mini datacenter too ) for a few days May 27 20:10:44 again its very rare. May 27 20:11:09 like 1.5m worth of equipment poof gone May 27 20:13:02 i think worst i've ever heard, was a couple of guys, walking into a datacenter, and carrying all computers out May 27 20:13:11 a $45 bbb or somethign like it could have saved the day ;) shut off al lthe euipment, until someone came out to repair the ac unit. site was goign down no matter waht . . . May 27 20:13:16 in broad daylight... passing the security guy May 27 20:13:19 lol May 27 20:13:45 Anybody here running a custom linux kernel on their BBB that they cross-compiled? I cross-compiled the archlinuxarm kernel and installed it but it didn't boot, no idea where I went wrong. May 27 20:13:45 iirc it took the company a couple of hours to realize that it wasnt a network problem May 27 20:14:08 hahaha May 27 20:15:00 tdill__ not exactly custom, followed Rbert C nelsons how to etc but yeah it was cross compiled. May 27 20:15:17 tdill__ whats teh symtoms ? other than it doesnt boot ? May 27 20:15:37 blue smoke? May 27 20:15:39 all 4 user LEDS lit solid ? May 27 20:16:00 m_billybob: haha, no smoke thankfully, but no lights at all, ever with the sd card plugged in May 27 20:16:46 id have to assume the power led comes on ? May 27 20:16:57 and no activity on the user leds at all ? May 27 20:17:00 m_billybob: the arch arm guys compiled the kernel with cpu scaling set to performance instead of ondemand like most other distros so you can't do very much off of usb power May 27 20:17:05 ever? did you wait an eternity? May 27 20:17:08 mru: lol May 27 20:17:11 m_billybob: oh yeah the powerled comes on May 27 20:17:21 OK guys, now a serious question. I have this Lexicon Omega thingy, an 4x2 audio+MIDI interface (full-speed USB1.1). It works when connected directly, doesn't work through a hub I got in 2 euro store. Some other audio interface (a $10 soundcard from ebay) works when connected to the same hub. I'm guessing I got a short end of the infamous 'split transaction' stick, amirite? May 27 20:17:37 mru: felt like forever lol May 27 20:17:51 mru: I even asked nicely May 27 20:18:15 tdill__, and you're using uboot with uEnv.txt ? May 27 20:18:17 eternity does feel long towards the end May 27 20:18:39 err wait this is from emmc or sd ? May 27 20:19:04 kfoltman: try a 3 euro store May 27 20:19:07 etc May 27 20:19:09 m_billybob: correct uing uboot, it's booting from an sd, it was booting the previous kernel from there May 27 20:20:01 mru: the same hub+audio interface combo works when connected to the PC, so I guess there's something different in BBB USB implementation that makes it not work May 27 20:20:03 m_billybob: I installed the kernel with the package manager, but was wondering if there was some other step that needed to be done May 27 20:20:18 tdill__ when first doing the same with debian, i had the exact same thign happen to me. as it turns out, I didnt copy the rootfs over proerly. May 27 20:21:13 the power LED would come on and nothing on the user leds May 27 20:21:37 m_billybob: hmmm, would I need to rebuild the rootfs after changing the kernel, that seems weird from a server/desktop perspective... May 27 20:21:37 the question is, apart from usbmon on the device (and perhaps the hub), what can I do to get some insight into packets exchanged between the board, the hub and the interface? May 27 20:22:54 tdill__ i didnt have to, but i did. initially, also when making a sd card for my buddy i did somethign else ( missed a step ) and the same happened from that too May 27 20:23:31 I'm not 100% sure if I want to deal with usb porn, but perhaps worth trying May 27 20:23:38 tdill__ whcih steps did you follow ? May 27 20:25:07 also for what it is worth i missed teh uboot steps completely initially also second try ang the bbb booted fine lol dont ask me how . . . May 27 20:25:25 m_billybob: ha, that's funny you ask, this is all the archarm tema has for cross-compiling: http://archlinuxarm.org/developers/distcc-cross-compiling May 27 20:25:52 m_billybob: the docs for building kernels is basically a link to their github page and a link to the arch x86 wiki May 27 20:26:20 m_billybob: it's been a long, but interesting 2 days of learning about cross-compiling (to some extent) May 27 20:27:39 someone else on here has archlinux working i dotn remember whom but you'd probably be better off talking to that person May 27 20:27:49 i have zero hands on with archlinnux May 27 20:28:02 those steps seem kind of short though May 27 20:28:07 m_billybob: do you still have that link to the debian tutorial you sent me? I may jump ship to debian, i was just hesitant to learn another packaging system since I already knew pkgbuild and rpm May 27 20:28:19 (OK, it's even more interesting: the cheapo hub works when connected via non-cheapo hub, but doesn't work when connected directly to the PC motherboard, I guess that explains much) May 27 20:28:25 may also give you some insight where it went wrong too May 27 20:28:30 and yes i do one second May 27 20:28:51 tdill__ ---> http://eewiki.net/display/linuxonarm/BeagleBone+Black May 27 20:29:01 m_billybob: thanks May 27 20:29:08 debian or ubuntu both are CLI May 27 20:29:10 np May 27 20:29:36 anyhew bbl got soe work to do ! May 27 20:30:06 m_billybob: yep I'm looking for cli, I just want a base system with a kernel I can hack on May 27 20:30:27 m_billybob: did you follow these steps on a debian system too? May 27 20:34:10 oh, http://pastebin.com/PjPKZQdi May 27 20:34:58 ick May 27 20:35:01 even better: "mmcblk0: error -110 sending status command, retrying" May 27 20:35:19 "Aborting journal on device mmcblk0p2-8." May 27 20:35:31 time for a reboot I suppose May 27 20:36:27 booting from waht? May 27 20:36:49 -110 is timeout May 27 20:37:01 Sicelo: from eMMC May 27 20:37:18 m_billybob: well I think I see my first error, I didn't cross-compile uboot May 27 20:37:34 sometimes 'rootwait' helps May 27 20:41:27 Sicelo: if you mean my mmcblk0 error, it was after the BBB was running for more than a day, and it works now after power cycle. May 27 20:42:01 ok. nice. May 27 20:42:22 Hi everyone, I've been doing my part to parse out May 27 20:43:18 shoot (accidental enter press)… to parse out any pros of the original beagle over the beagle black. Any major things I should be aware of? May 27 20:52:00 YoMomma: Section 4.1 p.25 of the BBB manual contains a list of the differences versus original BB May 27 20:53:53 fiola: excellent, thanks so much May 27 21:02:38 The README in root's login directory says that syslog-ng or rsyslog will run happily alongside the systemd journal if installed. There's no sign of either of those packages in an "opkg list" though, despite an opkg update. Is the README wrong, or opkg feeds not set up fully on BBB? May 27 21:03:22 Stock Angstrom on BBB, as it comes. May 27 21:04:55 Hi, does anyone know is somewhere u-boot for BBB that supports fastboot and GPT partitioning as well ? May 27 21:06:30 fiola: well, it only says that it can run happily, not that it's available anywhere in precompiled form ;) May 27 21:06:43 Silentjet, I'd ask that question on the Mailinglist/forums/googlegroups. May 27 21:09:07 well, actually it is :) inside rowboat repo May 27 21:09:21 But it require more work on it May 27 21:09:35 to adopt to GPT partitioning May 27 21:10:06 Silentjet, check how current the rowboat is... May 27 21:10:16 might be a leaky vessel. May 27 21:10:57 I already done that, booting is stuck on loading bootloader partition May 27 21:11:40 I guess cause wrong extra option is specifiev for target board am335x_evm May 27 21:11:43 kfoltman: Hehe. Well the more I explore Angstrom, the more that appears to be the case with many things. It's partial and broken in so many respects, especially in /etc/init.d. No idea though if it's just a spotty version of Angstrom on BBB, or whether that's a property of Angstrom. May 27 21:13:59 * janne curses systemd May 27 21:14:45 It's a bit worrying that it's giving the legions (hopefully :P) of new Linux recruits that buy a BBB a bad impression of how good and tidy Linux is. It's really complete and consistent on all the major distros, but Angstrom isn't. May 27 21:15:14 fiola: well, it's true - but comparing to my only alternative at this point (buildroot), I like the ability to edit/recompile the source directly on BBB, for quick checks/bugfixing/optimizations (of course I could just as well set up a cross-compiling environment on the host, but I'm lazy) May 27 21:15:18 janne: I don't mind change, I mind breakage. May 27 21:17:06 it can't even mount a nfs4 share on the default beaglebone black. it tries to mount it before the network is ready as static mount and uses options mount.nfs4 doesn't understand as delayed automount May 27 21:17:32 kfoltman: yeah, but for example, the Pi hordes are getting a better Linux experience right now because their Raspbian distro is a Debian, which is full and complete, not patchy and half broken. That's sad, BBB deserves better. May 27 21:17:48 janne: yeah, startup is a mess. May 27 21:17:53 bbb is not a desktop May 27 21:17:56 fiola: I was cursing about the breakage I saw myself May 27 21:18:07 it's a dev board May 27 21:18:40 fiola: part of me agrees with you - on the other hand, the opkg borkiness forced me to learn a few things that I wanted to learn, but would be too lazy to do otherwise ;) May 27 21:18:50 time to install gentoo on it May 27 21:18:54 thurgood: It's a new era with BBB. Beagleboard.org has decided to give it a desktop to make the out-of-the-box experience appeal to the masses. May 27 21:19:55 thurgood: well, RPi is a dev board, too, in theory :) May 27 21:20:26 or at least is sold as one ;) May 27 21:20:38 And in any case, startup breakage can't be excused just because "it's a dev board". Breakage is breakage. A dev board running Debian or Ubuntu or Gentoo won't have broken startup. May 27 21:21:12 "It's an embedded system. Abandon all yer hope." May 27 21:21:29 the rpi with all it's closed docs makes a poor dev board... but by labeling it a dev board you have easier fcc resrictions May 27 21:21:38 Hahaha. The opposite actually. Embeded systems need to work even more reliably :P May 27 21:21:55 fiola: The finished systems - yes. But the tools are usually horrendous. May 27 21:22:21 Poorly tested closed-source compilers etc. May 27 21:22:37 janne, whats the difference really between OE(made for embedded) and Gentoo (made for desktops)? May 27 21:22:52 ie: why is is any better in this case. May 27 21:23:17 they *both* are source based frameworks with recipies. May 27 21:23:44 kfoltman: Oh god, not talking about closed proprietary junk. I'm comparing Angstrom to distros like Debian and Ubuntu, which can easily be slimmed down and still work perfectly. May 27 21:24:08 ubuntu and slimmed down...in the same sentence! May 27 21:24:12 Haha May 27 21:24:12 heh May 27 21:25:01 thats like saying a whale lost 150lbs and thats "trim and fit" May 27 21:26:02 ka6sox: Gentoo isn't "made for desktops". It's a sort of meta-distro, or toolkit for constructing your own system. It'll make the *exact* system you want whether it be a desktop, server, router, or anything else. May 27 21:27:11 fiola, yes, but the recipies are setup *mostly* for x86 desktop and server environments and not checked for endian and other "safe" issues in cross compiling. May 27 21:27:24 Sabayon is a Gentoo-based distro created specifically for desktops, with all the glitz. May 27 21:28:03 OE otoh, has patches specifically meant to deal with Endian and other issues found in embedded environments. May 27 21:28:25 fiola: gentoo was created by big brother to improve electricity consuming xD May 27 21:28:34 no more no less May 27 21:28:48 Silentjet, turn electrons into Heat. May 27 21:28:59 to achive EXACT system u need LFS May 27 21:29:07 no more no less May 27 21:29:08 wonder what's the use of electricity from people constantly recompiling everything with various compiler options to get even better performance on high-end x86 machines ;) May 27 21:29:55 I'm not denying it has advantages for squeezing every last ounce of performance out of x86 desktops. May 27 21:30:22 OE *came* from Gentoo as a framework specifically for Embedded. May 27 21:30:37 and *optimized* for Embedded. May 27 21:31:24 forget about optimisation in common tasks :) GCC with O2 knows better how to do that May 27 21:31:31 Anyway, the subject was breakage in BBB's Angstrom. While Angstrom (and OE) may have admirable intentions, the breakage is not working to BBB's benefit. May 27 21:31:45 fiola, what breakage? May 27 21:32:13 The specific examples were systemd's startup of various things. May 27 21:32:50 startup is a system issue on a particular system...Gentoo won't "fix" that. May 27 21:33:38 tweaking an existing system to do what you want is cheaper than throwing the baby out with the bath water. May 27 21:33:49 especially if you already *know* gentoo. May 27 21:33:51 fiola: systemd sucks, and everyone knows that May 27 21:34:09 jacekowski: can't agree more. May 27 21:34:11 Not sure what you mean by that. I've never come across broken startup scripts on Gentoo, Ubuntu or Debian, not even on the otherwise crappy Pi. On BBB, they're badly broken. May 27 21:34:23 systemd together with pulseaudio and guy that came up with those two, should just burn in hell (or your local equivalent) May 27 21:34:28 So why are we using systemd, if we know it's badly broken? May 27 21:34:31 so fix them. May 27 21:34:48 ka6sox: You fix them, you're the pro advocate. May 27 21:35:10 gentoo has WORKING OpenRC and it works May 27 21:35:19 jacekowski++ May 27 21:35:27 and it does the job and it's compatible with systemV May 27 21:40:31 and well, gento does a lot of things better than most of the distros (other than the fact that installation is slow for obvious reasons) May 27 21:42:44 I'm not trying to promote one distro over another, I've used so many I've lost count over the years. But breakage isn't tolerable in any distro, and if major changes are made (like removing /etc/inittab, FFS!) then there have to be VERY strong reasons and advantages for it. And the result must not be broken. May 27 21:43:56 thing is, linux and backwards compatibility don't go very well together May 27 21:44:55 if you have some commercial binary only software that relies on libc then in most cases libc will ship with that software because next update to glibc will be incompatible with old one May 27 21:45:26 I'm not even saying that it has to be backwards compatible. But when moving purely forwards without a rearview mirror, the result must not be broken. May 27 21:46:17 ah tdill left already May 27 21:46:33 and well so far i've seen only one workaround for the problem that works quite well (windows side-by-side - but this still is a workaround) May 27 21:47:25 jacekowski, different story for debian usually. May 27 21:47:26 that allows for security update to older version of libraries that are kept for compatibility reasons, and at the same time, allows for new version to coexist May 27 21:48:21 In the absence of inittab, where does one configure the VTs on which logins are to be spawned? May 27 21:53:21 fiola, seems you've cleared the room with your question ;) May 27 21:53:41 Think I found the info, something to do with messing around with getty* files in /lib/systemd/system/ May 27 21:53:43 Haha May 27 22:18:00 where's a good small angstrom image for BBB? The "current" version linked on the getting started page is over 3GB. May 27 22:23:55 fiola: ...so now I have a systemd .service file for my instrument thingy ;) May 27 22:24:38 it's very hacky but it kinda works (by which I mean it starts it on bootup, then it crashes, then it restarts it, and then it works :O) May 27 22:29:21 Haha. I guess that's progress :P May 27 22:31:08 It's more than good enough for now. May 27 22:43:57 mastiff: not sure what you're seeing, the ones here are <500MB: http://downloads.angstrom-distribution.org/demo/beaglebone/ May 27 22:44:52 BBB-eMMC-flasher-2013.05.20.img.xz ? May 27 22:45:11 that ones just 300M May 27 22:45:14 364MB compressed May 27 22:45:24 after 7zip it ended up over 3GB May 27 22:45:34 joel_: Hah, just in time, I was about to look for that URL, cheers :P May 27 22:45:50 :) May 27 22:45:54 not sure if that's correct?? May 27 22:46:06 Finger trouble, zapped a file, lol May 27 22:46:08 mastiff: dunno, i have never used the flasher images May 27 22:46:17 i don't even boot from eMMC , sorry May 27 22:46:42 i ran out of disk space on my BBB so that's why I need to do this May 27 22:47:29 but the pre-installed angstrom is less than 2GB May 27 22:47:56 I read in the BBB manual that the eMMC device that Gerald used is pin compatible with devices up to 8GB in size. Looking forward to BBs with large eMMC :-)))) May 27 22:48:23 is anyone here running ubuntu on their BBB that has it install on the emmc? May 27 22:48:46 i have a 16GB sd card I'm working with now, is that incompatible? May 27 22:49:18 mastiff not necessaily May 27 22:49:48 some cards may not work, but most well known brand seem to work fine May 27 22:50:07 ( we have two bbb's both using 16GB cards ) May 27 22:50:52 That's good to kinow, m_billybob May 27 22:51:02 Brand? May 27 22:51:05 how large is the image you flashed on them? May 27 22:51:08 samsung May 27 22:51:13 cheers May 27 22:51:35 mastic started with a netinstall image so it was tiny May 27 22:51:40 mastiff* May 27 22:51:47 374MB May 27 22:52:26 mdp is reaalllyy busy these days :-) May 27 22:52:32 - Filesystem Size Used Avail Use% Mounted on May 27 22:52:33 - /dev/root 15G 444M 14G 4% / May 27 22:52:35 374MB image or .xz? May 27 22:52:54 so is jkridner_ May 27 22:53:11 m_billybob: Quick, get more, you're running out! :P May 27 22:53:20 mastiff whole install. kernel rootfs etc May 27 22:53:27 i know right ?! May 27 22:53:49 ka6sox: it seems that I have to disable the osc that drives the HDMI audio over mcasp0 May 27 22:53:50 mastiff this is debian CLI though May 27 22:54:03 i would think angstrom could be had at aroudn the same footprint May 27 22:54:13 ( cli ) May 27 22:54:14 hmmm, ok, I don't understand why the current BBB angstrom i just downloaded is over 3GB. May 27 22:54:46 Oh that's the Microsoft rootkit May 27 22:54:48 as Gerlad put it. its an install image, so going ot be bigger but will fit on hte emmc May 27 22:55:23 Gerald* May 27 22:55:34 sorry multitasking here typing too fast . . . May 27 22:56:14 fiola: lol May 27 22:56:45 fiola, ill assume you mean Sony rootkit ;) May 27 22:57:41 the Microsoft "rootkit" would be know as Windows . .. May 27 22:57:49 It's soo huge it's gotta be the HB Gary version May 27 22:57:50 known* May 27 22:58:57 mastiff never done this myself but for what it is worth, on the groups there are instruction for dding what you need out of that image May 27 22:59:21 Sony are the proud originators of the rootkit marketing concept, but Microsoft are somehow justifying substantial royalty fees per Android device, so I suspect they're trying to inject stuff into Linux too :P May 27 22:59:48 was ther esome ms rootkit scandal i havent heard of yet ? May 27 23:00:02 * m_billybob hasnt been followign microsoft security stuff for several years now May 27 23:00:06 Nah, but don't lose hope :P May 27 23:00:17 yeah I'll try that, the SD i just flashed doesn't boot May 27 23:00:20 they've fooled you ! its called Windows ! May 27 23:00:34 fiola ^^ May 27 23:00:35 MS is all derivative these days, so they'll prolly license the rootkits from Sony :P May 27 23:00:55 Sriously i run Windows 7 x64 all day every day I couldnt be happier May 27 23:01:01 I wouldnt ru na server on it though May 27 23:01:29 pure desktop im good i leave the heavy lifting for debian May 27 23:02:10 well let me rephrase, i wouldnt knowingly / willingly ru na server on it ;) May 27 23:02:20 what does it mean if all the leds are on May 27 23:02:35 MS isn't a worry anymore anyway. Google is the big worry that's heading our way. May 27 23:02:46 as in you put in the sd card and they're lit solid ? May 27 23:03:05 fiola, hence why ill never touch android again May 27 23:03:07 as in the sd card is not in and i've rebooted several times and they stay solid May 27 23:03:17 sounds like a bad flash May 27 23:03:26 which is fixable May 27 23:03:51 it should be booting off the internal, but it doesn't seem to be May 27 23:04:15 sounds like you got / had a wonky flash. did you try flashing a new image ? May 27 23:04:55 if you power it up, and it go straight to all 4 usr leds lit solid and it doesnt change, it wont boot May 27 23:04:56 i tried flashing the current BBB angstrom image on the 16GB SD May 27 23:05:15 it won't boot off the 16GB May 27 23:05:31 reason ? May 27 23:05:32 and now it won't boot off the internal 2GB May 27 23:05:55 how have you been shutting down the bbb ? May 27 23:06:23 yanking power or are you using shutdown now -h from ssh ? May 27 23:06:24 shutting down? May 27 23:06:33 unplugging or reset button May 27 23:06:40 * m_billybob winces May 27 23:07:09 future reference use shutdwn -h now or shutdown now -h May 27 23:07:12 same difference May 27 23:07:26 shutdown now -h* May 27 23:07:55 the internal is 2Gb... not GB May 27 23:08:00 Hmm, if that's important and capable of damaging a device, it should really be in the Getting Started May 27 23:08:24 doubt the device is damaged May 27 23:08:26 mastiff thats common linux knowledge May 27 23:08:37 yeah not damaged but posibly corrupted now May 27 23:08:39 yeah that's right storage is normally in Gb May 27 23:09:02 depends on the medium May 27 23:09:16 mastiff: if it's not in the Getting Started then it's an important omission. May 27 23:09:44 people like me who are switching from arduinos and such aren't necessarily aware of that May 27 23:09:50 got to look at it like a desktop PC how do you shut that down ? May 27 23:09:51 had drives are generally in 10^9 B May 27 23:10:11 little b being bit May 27 23:10:25 anyhow moot now. now you know :) May 27 23:10:27 *hard May 27 23:10:37 Just because it's common knowledge in the Unix world doesn't excuse it not being documented in a device that (because of price) every man and their dog and their dog's flees will buy, because of price. May 27 23:11:13 so if you try putting more than 256MB on there.. probably not going to work May 27 23:11:18 two sides to tha tcoin though May 27 23:12:17 mastiff do you have a regular linux machine handy ? May 27 23:12:24 yeah a couple May 27 23:12:36 what type of install are you looking for ? May 27 23:12:39 on the bbb May 27 23:13:15 i had just finished installing rtl-sdr on my BBB, and tested that. worked fine May 27 23:13:26 then started to install gnuradio and ran out of disk space May 27 23:14:22 i want something small and fast not a full ubuntu or debian and such May 27 23:14:47 wel both the installs ive seen for debian and ubuntu are cli and small May 27 23:15:04 oh, than I'd give that a try May 27 23:15:06 unless you think smaller than 400MB is large May 27 23:15:29 i think the 3GB BS i just downloaded from the BBB site is large May 27 23:15:30 Angstrom on BBB comes with X11 and desktop, so it's not slim by any stretch of the imagination. May 27 23:15:33 Gb May 27 23:15:47 no GB May 27 23:16:05 fiola, has anyone done an angstrom console-image yet and online ? May 27 23:16:16 3.5GB actually May 27 23:16:22 i havent heard of one but no one say i have to know everything May 27 23:16:27 m_billybob: excellent question, don't know May 27 23:16:38 id be willing to try it myself May 27 23:16:41 ditto May 27 23:16:54 well what about older versions say 3.8.8 May 27 23:17:02 i know that one works May 27 23:17:05 well it did for me May 27 23:17:09 fiola: yes, #exactsteps are required May 27 23:18:02 not necessarily exact step but atleast some semblance of sane toolchain setup would be nice May 27 23:19:17 I was talking about the poweroff May 27 23:19:19 I actually agree fully with the approach taken for BBB, basic desktop provided over HDMI so that the masses have what they are prolly expecting. It's required because of the low cost of BBB. However, almost all people using BBB for embedded will prolly want to zap the entire X11 system from eMMC ... and that's not supported currently. May 27 23:19:20 define works? May 27 23:20:17 joel_, +1 May 27 23:21:31 I have two BBBs and it looks like the bad SD flash at least temporarily bricked both of them. Neither will boot now after trying to boot that SD. May 27 23:21:38 problem is and I will always find a way to make the bbb work if there is way. Most users are likely not going to know the hardware well, or even linux, and when you give them instructions that dont work, because its changed like 500 times in the first month . . . thats a bit of a problem May 27 23:21:43 i will agree with that May 27 23:22:08 mastiff, I came in late..what did you try to do with the SD card? May 27 23:22:34 ka6sox, remember last night I was compiling rtl-sdr? May 27 23:22:44 I got that to work today May 27 23:22:59 kewl May 27 23:23:24 several compiling errors complaining of missing package but the package was actually installed May 27 23:23:31 needed the -dev May 27 23:23:39 http://eewiki.net/display/linuxonarm/BeagleBone+Black May 27 23:23:40 right, makes sense May 27 23:23:54 thsoe are the instructions i followed for debian mastiff May 27 23:23:58 m_billybob: well the biggest "instruction that doesn't work" currently is that the manual says it's important to upgrade the system, yet as many people arriving here have reported, the upgrade leaves the eMMC unbootable. That's clearly ... suboptimal. May 27 23:24:04 yup, so then I started compiling gnuradio and ran out of disk space May 27 23:24:17 whoops May 27 23:24:26 fiola, I'm trying to get that corrected... May 27 23:24:42 Woohoo! ka6++ May 27 23:24:42 fiola, yeah, id hate to be one of the guys workign on these problems rigth now May 27 23:24:47 then tried to flash the "upgrade" which completed successfully according to the flash program May 27 23:24:52 the upgrade wasn't correctly specified to use the same proceedure as for the original May 27 23:25:17 now on both my BBBs after trying to boot off the newly flashed SD, they won't boot with or without the SD May 27 23:25:31 mastiff, do you have a console connected to either one? May 27 23:25:39 (or can you connect one? May 27 23:25:40 ) May 27 23:25:49 console? May 27 23:25:55 serial cable May 27 23:25:57 serial port to the pins May 27 23:26:06 via a FTDI or something May 27 23:26:47 we still dont have one of those yet either . .. May 27 23:26:53 we need one though May 27 23:26:54 no, but I might have parts to make one May 27 23:27:05 mastiff, Q2: does the flasher boot again, and start the process over? May 27 23:27:23 got a 3v3 ttl serial module ? May 27 23:28:15 Or use another BB and a couple of wires. May 27 23:28:17 without the SD card, one BBB is now booting and all the leds stay solid, and the other has only usr3 lighting May 27 23:28:32 Or a Bus Pirate. There's tons of ways of getting serial console. May 27 23:28:40 arrrr May 27 23:28:41 msp430 . . . May 27 23:28:54 well msp430 with USCI May 27 23:28:56 i have some arduinos, msp430, logic analyzer May 27 23:28:58 okay mastiff, try to reflash the "other" May 27 23:29:06 the one that doesn't boot May 27 23:29:11 neither boots now May 27 23:29:39 okay...this sounds like a bad flash May 27 23:29:46 which version are you using of the flasher? May 27 23:29:59 the one that was linked from the Getting Started May 27 23:30:10 can you give me a number? May 27 23:30:14 just a sec May 27 23:30:54 win32diskimager-v0.7-binary.zip May 27 23:32:50 mastiff, how many dog do you have ? May 27 23:32:54 dogs* May 27 23:32:59 Just two May 27 23:33:03 Just curious we have one english mastiff here May 27 23:33:22 Oh real dogs, yeah two of those also May 27 23:33:30 Cane Corsos, Italian Mastiffs May 27 23:33:39 yeah figured you'd have atleast one lol May 27 23:33:42 ah May 27 23:33:59 English Mastiffs are a lot bigger May 27 23:34:06 uh May 27 23:34:16 think the female we have here is semi small at only aroudn 120lbs May 27 23:34:17 mastiff, thats not an image May 27 23:34:25 thats the app that creates the image May 27 23:34:28 no that's the flash program May 27 23:34:35 mastiff he wants to know the file name of the image inside thezip May 27 23:34:39 sorry, was confused on what you wanted May 27 23:35:23 m_billybob: Did you select the defaults in the kernel config menu when cross-compiling the Debian kernel? May 27 23:35:35 esc esc yes May 27 23:35:48 i dont know enough about the kernel settings yet to muck with it May 27 23:36:44 m_billybob: yeah I fiddled with the ones that I changed in the arch kernel and didn't get it to boot, but I got lights, trying now with defaults before I get fancy May 27 23:36:58 tdill, incase my crypto talk is too cryptic lol yes i used default settings May 27 23:37:13 sorry i know i mabotu as easy to converse with sometimes as a dill pickle May 27 23:37:16 m_billybob: nah I got it :) May 27 23:37:58 ah right on May 27 23:38:08 so gettign somewhere closer now hopefully May 27 23:38:51 ka6sox: checking that, had to reboot..... May 27 23:38:52 yeah if I get the debian kernel to boot I will be at the same point with arch, but the cross-compilation process is much simpler with debian so far May 27 23:39:09 mastiff, https://s3.amazonaws.com/angstrom/demo/beaglebone/BBB-eMMC-flasher-2013.05.20.img.xz? May 27 23:39:40 99% sure that's the one I used, and decompressing with 7-zip yielded a 3.5GB file May 27 23:39:46 tdill looked like those instructio nrely heavily on massive bash scripts. only saying that because ther instructions there are way smaller than those i took for debian May 27 23:40:23 mastiff, ya, thats the current image May 27 23:40:32 Hello there May 27 23:40:41 yeah I remember 5/20 May 27 23:40:59 mastiff, can you please see if the process starts over again with that Image on your SD card? May 27 23:40:59 tdill, but who knows if you're familiar with , and happy using debian you may not look back ;) I've been beating the crap out of mine, and its still goign strong May 27 23:41:12 Anyone has ever ran asterisk on beagleboard May 27 23:41:27 what do you mean the process? May 27 23:41:38 Cris_, I've seen reports that it does...but I have not May 27 23:41:43 m_billybob: the niceest part is that I don't need the same host distro with the linaro cross-compiler tools, so I can build on bare metal in fedora instead of a vm May 27 23:41:54 mastiff, starts reflashing May 27 23:41:59 sorry i know i mabotu as easy to converse with sometimes as a dill pickle May 27 23:41:59 I'm booting back into windows to used that flashing program May 27 23:42:00 Still trying to parse that :P May 27 23:42:02 goes thru it cycle May 27 23:42:13 just a sec, got stuck in chkdsk hehe May 27 23:42:17 m_billybob: much faster! and youre right I may stick with debian May 27 23:42:24 Anyone has ever ran asterisk on beagleboard May 27 23:42:28 mastiff, whoops May 27 23:42:29 m_billybob: until someone has a decent fedora port May 27 23:42:36 tdill, sweet, im partial to debian, so that one of my cross dev systems. the other is lol Windows May 27 23:42:56 ive been writting all userland apps so far whcih isnt many from windows May 27 23:43:00 Cris_, repeating the question won't get it answered any better. May 27 23:43:11 Sorry May 27 23:43:35 fiola, just means that sometimes im in my own world and i may not make sense to some. May 27 23:43:35 m_billybob: nice, are you using cygwin or do they have windows port of the cross-compiler? May 27 23:43:44 Cris_, I'm sure google will find a howto for this. May 27 23:43:44 Hehe May 27 23:43:48 tdill, using native win32 linaro May 27 23:44:11 ok, will check May 27 23:44:59 m_billybob: cool, I only boot into windows every once in a while at work when I have to test hardware besides that I'm usually in linux and a lot people find that weird, everyone has different prefs May 27 23:45:15 mastiff, can you md5sum the image you got before deflation? May 27 23:45:21 er inflation? May 27 23:45:22 you know for me windows is where its at for a desktop i cant help it :/ May 27 23:45:41 mastiff, http://downloads.angstrom-distribution.org/demo/beaglebone/ May 27 23:45:45 thet md5sums are there. May 27 23:45:51 sure, how do I check that in windows? May 27 23:46:01 you probably don't May 27 23:46:12 I don't use windows for this so I can't tell you how...sorry ;( May 27 23:46:19 7zip displays md5sums iirc May 27 23:46:41 m_billybob, thanks.. May 27 23:46:50 I wonder if anyone's produced a "Debian embedded" image, meaning just a basic CLI image with a set of tools typically useful for embedded work preloaded. May 27 23:46:55 what about on ubuntu? May 27 23:47:04 fiola, mrpackethead uses it May 27 23:47:13 whether its a custom to his app or not I don't know May 27 23:47:31 Interesting, I'll query him when he appears next May 27 23:47:32 fiola, debootstrap May 27 23:47:59 * fiola googles May 27 23:48:18 debootstrap is your friend May 27 23:48:52 http://wiki.debian.org/Debootstrap -- sounds very cool May 27 23:48:54 mastiff, md5sum filename May 27 23:49:20 it is May 27 23:49:34 well ive only used it once several years ago, very cool May 27 23:49:55 fiola, but im booting debian on my bbb what exactly do you mean ? you mean as in a dev platform ? May 27 23:50:32 fiola becaue it comes with lots of stuff on it, and is still under 400mb size so lol could add anythign you wanted May 27 23:51:15 CLI dev platform, sure. Any Unix is a dev platform, unless one has specifically excluded gcc. What's left prolly fits in 128k :P May 27 23:52:24 tools for embedded work <--- yeah something i dont exactly know all abotu either May 27 23:52:38 embedded linux is new to me May 27 23:52:46 Non-dev platforms are very important too for embedded, ie. just delivery targets. Just means stripping a whole lotta stuff out. May 27 23:53:00 i still need to figure out which libs/headers i need to bring over onto my windows box May 27 23:53:20 ka6sox: e9561c4e6b1ce7ecec74acc912cd27c1 May 27 23:53:28 m_billybob: Does your sd card look like this, seems strange that the remaining space is at the beginning: http://snag.gy/PPgsE.jpg May 27 23:53:43 fiola, it comes with apache loaded and running a simple static web page ? good enough ? May 27 23:53:43 mastiff, compare it to the md5sums on that webpage I liked. May 27 23:53:45 heheh May 27 23:53:45 linked May 27 23:54:34 apache on an embedded system? Hurt me Baby! Make me write Bad Checks! May 27 23:55:19 tdill i think this is my sd May 27 23:55:30 I think we've just arrived in a new era, where embedded delivery targets cost peanuts and yet can hold and run an entire Unix-type O/S. Next generation beyond uClinux, which is probably dying as a result. May 27 23:55:44 - /dev/mmcblk0p1 * 2048 133119 65536 e W95 FAT16 (LBA) May 27 23:55:44 - /dev/mmcblk0p2 133120 30702591 15284736 83 Linux May 27 23:55:46 m_billybob: ok, thanks just seemed unusual May 27 23:56:11 looks normal to me May 27 23:56:13 m_billybob: ah you dont have that, hmm, May 27 23:56:20 dont have what ? May 27 23:56:35 if I'm looking at the correct numbers, it's not the correct md5 at all/??? May 27 23:56:42 the free space at the beginning May 27 23:57:20 tdill no i dont May 27 23:57:24 fiola: http://8devices.com/product/3/carambola May 27 23:57:31 atleast fdisk -l isnt showing it May 27 23:58:20 I want to put my beaglebone (either white or black) in my car and power from 12V->5V reg. will I need to make a circuit that detects when power is cut to the 12V and auto-shutdown or can I mount the sd card as readonly and have it safe to just unplug power? May 27 23:58:51 tdill, i did an equivenet in terms of drives you have . . . -> sde complete wipe, then hand created both needed partitions and nothing more May 27 23:58:57 read-only is always safe May 27 23:59:00 tdill has tha tsd been in a windows box ? May 27 23:59:21 m_billybob: no it's only been connected to linux since I bought it May 27 23:59:40 so it won't hurt/corrupt the SD card if I am constantly starting up and pulling power, as long as the SD card mounts as RO? May 27 23:59:52 ah ok, well i asked because windows created some funky partition like that too May 27 23:59:54 ka6sox: my BBB-eMMC-flasher-2013.05.20.img.xz appears to be correct size, May 28 00:00:00 creates* May 28 00:00:11 m_billybob: I was considering manually partitioning, I think I'll do that May 28 00:00:29 it'll make your life easier May 28 00:00:48 plus watch out for automount gah pissed me off many times during that process May 28 00:02:00 dinner time though May 28 00:02:05 m_billybob: haha yeah, luckily it won't automount for me unless I open the drive in the fs explorer May 28 00:02:05 ill be back in a bit May 28 00:05:39 SeeMitch, you might not need to worry about it under normal use. Beaglebone won't drain enough power to kill your car battery unless you leave it for probably a week. May 28 00:06:58 You could use the switched power circuit in the car wiring though to trigger shutdown. May 28 00:06:59 SeeMitchPlay: This isn't related to your question directly, but you just reminded me of a study which appeared on Slashdot about what happens to SSDs when you just pull the plug out. 8/10 brands would die occasionally, some of them every single time. Only Intel's survived 100%. May 28 00:07:35 mastiff, try to reimage the SD card again and see if it boots May 28 00:07:41 Well, I'm planning on running it off my 12V adaptor, which auto-kills when the car engine shuts off. I guess I can run power straight from the battery but I was thinking of having a little rechargable battery between the 12V and the BB. And when loss is detected, it'll init 0 the BB May 28 00:07:57 Ok, i have to boot back into windows to use that program..... May 28 00:09:05 maybe i'll just have a hardbutton that I push once I park and then it'll toggle the init 0 May 28 00:09:11 there is a programme that does it in linux too. May 28 00:09:24 If you run it straight off the battery you will always have voltage until the battery is dead. There is another switched circuit that has 12V only when the key is in the ON position. Use that to shutoff your BBB. May 28 00:10:11 yea, that's what i was planning on doing, but then when i turn the key off, the BBB will shut off right away without unmounting the disks May 28 00:10:18 SeeMitchPlay: BBB has battery charging connections (unpopulated) ... there might be something you can leverage there, keep it running off a small Li-Ion during orderly shutdown. May 28 00:10:45 oooo, i thought that only kept the RTC going May 28 00:10:53 No, have the BBB powered straight from the battery, and use the switched power to shut it off. see? May 28 00:11:09 ah. good call May 28 00:11:13 mastiff: That makes sense. May 28 00:11:26 okay, I'll probably end up doing that. thanks May 28 00:12:39 I have a scrolling marquee display that I'm going to use to send messages to stupid drivers. (like "Blinker?!") this shall be quite fun May 28 00:12:48 sure, yeah I know more about vehicle wiring from building my sailboat than I do about flashing SDs May 28 00:12:57 or linux hehe May 28 00:14:41 you can get some high efficiency 12V to 5V 2A dc-dc converter boards on ebay for a couple bucks, that's what I have to use for my BBB on my boat May 28 00:15:27 mastiff, I'm going to have to leave now, we have a brush fire here that is burning out of control...bbl May 28 00:15:40 Eeeek! May 28 00:15:58 be safe May 28 00:16:12 fire is fun until it's not May 28 00:16:46 just like everything else ^ May 28 00:35:21 ah good dinner May 28 00:37:19 baking salmon and reflashing SD over here May 28 00:38:01 heh i ate leftovers from the get together we had this weekend, someone brought taco salad, and a dahmed good one May 28 00:39:07 now I' hungry May 28 00:39:15 lol May 28 00:39:29 nice, I'd rather be eatting leftovers than having to cook May 28 00:39:56 well if thats fresh almon id rather have what you're having May 28 00:40:02 salmon* May 28 00:40:32 lived in the N Bay calif area for years now im inland no where near good fresh sea food May 28 00:41:07 frozen from parents freezer hehe May 28 00:41:12 I figured you were west coast if you were just now eating dinner May 28 00:41:22 looking forward to catching fresh seafood while sailing May 28 00:41:26 arizona May 28 00:41:31 chicago area May 28 00:41:47 oh, misread May 28 00:42:05 mastiff is same as me, so youre more west than us a but :) May 28 00:42:09 alright, botting the reflash May 28 00:42:11 a bit* May 28 00:42:12 booting May 28 00:42:33 m_billybob: what did you say you did wrong when you had no lights on boot (excpet power)? May 28 00:42:58 couple different thigns, but first time i copied rthe rootfs over wrong May 28 00:43:26 tdill, what i ended up doign was install sudo and doing EXACTLY what he did to avoid issues May 28 00:43:28 apparently what I did wrong was following the Getting Started update to latest software instuctions May 28 00:43:43 mastiff, do not upgrade May 28 00:43:55 opkg update == fine opkg upgrade == bad May 28 00:44:01 i had zero problems until that, now both BBBs won't boot May 28 00:44:37 m_billybob: could of swore I did, using sudo here too, I'll try to extract the rootfs again just to be sure May 28 00:44:42 they're having problem with opkg upgrade right now. i dotn know the details but Gerald said on the groups dotn use it until further notice May 28 00:44:54 tdill, do this May 28 00:44:58 open a text file May 28 00:45:07 copy each command as you complete them into it May 28 00:45:14 that helps a lot May 28 00:45:26 and if somethign goes wrong then you have a recipe for fixing it May 28 00:45:28 Oh I see what you are saying, but the problem I had happened after flashing onto SD, not opkg related May 28 00:45:59 masstiff could be related ive heard peopel having isues with some of the newer flash images too May 28 00:46:07 * ketas wonders about correct smd led May 28 00:46:13 but i dont know could be user error May 28 00:46:23 errr, i hate this enter always getting in way May 28 00:46:29 i had finished compiling and testing rtl-sdr, then went onto compiling gnuradio, but ran out of disk space, so I was just trying to flash an image to boot off my 16GB SD May 28 00:46:32 m_billybob: will do, I can't believe I'm running into so many issues, my dog did decide to destroy a cardboard box while I was in the process so maybe I missed someting May 28 00:46:32 correct smd led replacements May 28 00:46:46 heheh May 28 00:47:14 tdill, you're doing this from fedora ? maybe time to setup a chroot and make thigns even more interresting ? lol May 28 00:47:14 non-transparent green, red & orange May 28 00:47:32 yeah woldnt be high on my list either May 28 00:47:44 so the reflash attempt results in all solid leds May 28 00:47:46 seems like pretty sucky soldering job, though May 28 00:47:53 m_billybob: hah yeah, you might be right May 28 00:47:59 world is too small now May 28 00:48:00 masstiff May 28 00:48:13 mastiff even after reboot the bbb ? May 28 00:48:17 yes May 28 00:48:24 wtf. May 28 00:48:52 i'll try booting again, then without the SD, then in my other BBB May 28 00:48:56 you did take teh sd card out ? May 28 00:49:02 no take it out now May 28 00:49:10 k May 28 00:49:12 lol thats why it wont boot May 28 00:49:13 out May 28 00:49:31 neither will boot with SD though May 28 00:49:34 without May 28 00:49:46 how so May 28 00:49:51 what boot process are you using ? May 28 00:50:07 just plugging it in and letting it boot ? May 28 00:50:13 pressing buttons ? May 28 00:50:31 without SD, one BBB will boot into solid leds, the other boots into only usr3 led May 28 00:50:40 no buttons, just reset, or powering May 28 00:50:44 that system is not breakable with obvious ways May 28 00:51:03 mastiff, YMMV but ive found reset to be flaky May 28 00:51:06 sd card needs boot rearrangement with boot button pressed down May 28 00:51:07 without the SD this one is booting into only usr3 led May 28 00:51:15 e.g. i unplug replug the board to power it May 28 00:51:28 doing that now May 28 00:51:35 the power button doew what? May 28 00:51:50 powers board up May 28 00:51:50 as opposed to rest? May 28 00:51:51 left of the ethernet plug ? May 28 00:51:53 or right ? May 28 00:51:57 left May 28 00:52:08 directly left, reset far left May 28 00:52:09 thats the boot button iirc S2 May 28 00:52:29 i thought boot was far left from ethernet?? May 28 00:52:36 boot/reset May 28 00:52:39 oh think thats reset May 28 00:52:44 it's labeled well May 28 00:52:47 closest to ethernet jack is reset i believe May 28 00:53:02 ketas not well enough for 46 year old eyes apparently May 28 00:53:05 unless you can't see fine print, all things are clearly labeled May 28 00:53:06 oh May 28 00:53:09 unless its 5 foot tal and neon i aint seeing it May 28 00:53:11 far left is what has rebooted on my board May 28 00:53:15 maybe magnifier then May 28 00:53:17 :) May 28 00:53:51 heh i hae it my eyes jus tstartign goign on me within the last 8 or so months May 28 00:53:55 drives me nuts May 28 00:54:00 printing is pretty good, boards are well made May 28 00:54:24 although i admit that text is very small May 28 00:54:31 just a little 2x or 3x mag helps huge though May 28 00:55:05 maybe we need larger text for buttons? May 28 00:55:14 if i shine a led flashlight on it i can see it ok May 28 00:55:18 the buttons are too small May 28 00:55:42 well you know what though for $45 its a dahmed solid piece of hardware May 28 00:55:57 dahmed solid for a $100 piece of hardware May 28 00:56:24 mines been exceptional so either I got a very good board, or . . .im less prone to user error, and trust me May 28 00:56:32 ive cursed mine many times already May 28 00:56:33 It's great to be able to compile linux programs on an slightly more expensive arduino replacement May 28 00:57:03 i was really happy running rtl-sdr, then I bricked both my BBBs May 28 00:57:20 im not familiar with rtl-sdr May 28 00:57:44 debian is pretty much where my linux experience stops. though have lots of hands on with ubuntu too years back May 28 00:58:26 i plan running fbsd there May 28 00:58:30 once i get microsd May 28 00:58:45 i never felt at home with fbsd . . .dotn know why May 28 00:58:46 i should also fix the flash content May 28 00:58:49 so it boots May 28 00:59:02 rtl-sdr is software to turn a cheap $20 video tuner into a software defined radio that recieves from 60MHz to over 2GHz. May 28 00:59:23 http://sdr.osmocom.org/trac/wiki/rtl-sdr May 28 00:59:37 ill read it some later May 28 00:59:45 i was tuning into my local FM stations on my BBB May 28 00:59:45 i should get one of those i guess May 28 00:59:52 mastiff: hahaha May 28 00:59:55 my buddy is actually a radio station engineer so possibly rigt hup his alley May 28 00:59:59 for $20 !!! May 28 01:00:12 fm radio is cheaper May 28 01:00:14 :) May 28 01:00:30 you can also listen into police radio, or damn near anything else May 28 01:01:00 900mhz phones, gps, lots of stuff May 28 01:01:02 weather radio May 28 01:01:03 i wonder if that's still open May 28 01:01:04 marine rado May 28 01:01:05 the police May 28 01:01:14 some trunk the signal May 28 01:01:14 i bet somewhere it is May 28 01:01:21 most are easy to listen to May 28 01:01:30 gps, hah May 28 01:01:36 did you manage to receive gps May 28 01:01:46 someone received weather satellite May 28 01:01:52 cops dont encryt their frequencies ? May 28 01:01:58 most don't May 28 01:02:13 I didn't yet, but many other have May 28 01:02:24 hmm maybe they are using tetra here now May 28 01:02:30 that broken stuff May 28 01:02:36 if you guys want free software defined radio hardware sign up for this project https://greatscottgadgets.com/forms/hackrf-beta-reg.html May 28 01:03:04 hmm May 28 01:03:11 this one can rx and tx from 30MHz to 6GHz May 28 01:03:25 hah May 28 01:03:39 free, eh? May 28 01:03:53 darpa paid for like 500 boards to be made and given away!!! May 28 01:04:06 ketas: that's too expensive :P May 28 01:04:17 fiola: tetra? May 28 01:04:19 hmm wonder if that could be used as a FM radio tuner lol May 28 01:04:21 fiola: or what May 28 01:04:25 err May 28 01:04:35 FM tower tuner May 28 01:04:42 yes and transmitter, plus it can be used with an amplifier to jam any frequency May 28 01:04:43 mastiff: looks awesome May 28 01:04:54 of gsm base station May 28 01:04:58 tons of stuff May 28 01:04:59 radar May 28 01:05:40 mastiff, i dont know the proper term for the equipment but my buddy very recently needed a piece of equipment to tune an FM tower and had to buy one. May 28 01:05:46 * m_billybob isnt an EE May 28 01:06:06 I just hand aroudn one daily lol May 28 01:06:14 mastiff: what's requirement for getting hw? May 28 01:06:16 when it gets into high power stuff it's a differnt ball game May 28 01:06:20 sign up May 28 01:06:21 nothing is free May 28 01:06:25 A knife can be used to kill people or to slice courgettes. SDR is a sharp knife, but only sociopaths will disrupt civilization with it. May 28 01:06:49 Mike gave out codes to people at some conferences so they get first dibs May 28 01:06:52 says you need an invitation code May 28 01:07:11 you can sign up without the code, but codes get priority May 28 01:07:32 i seem to miss the point May 28 01:07:42 They extended the sign up already, there is a paradox about free. May 28 01:07:43 why should anybody give hw out for free May 28 01:07:52 Because the gov paid for it. May 28 01:08:04 and what is reason to give hw for free? May 28 01:08:26 ketas: why should anybody give hw only for profit? May 28 01:08:35 Probably because so much wireless stuff on unsecure frequencies is antiquated and totally unsecure. May 28 01:08:57 obscure frequencies i mean May 28 01:09:18 Update 16 May 2013: I'm extending the code redemption deadline from 20 May to 27 May. Tell a friend! May 28 01:09:21 hah May 28 01:09:24 what language does one write code in, for an sdr? May 28 01:09:26 so it's over? May 28 01:09:31 no it's still on May 28 01:09:47 27 may on what timezone May 28 01:09:51 any language May 28 01:10:03 just email mike, May 28 01:10:10 it's may 28, 04 here May 28 01:10:14 c++ or C May 28 01:10:17 usually May 28 01:10:22 scripted also May 28 01:10:34 you use the host to do the radio processing May 28 01:10:43 right, the freq range is pretty nice for a low cost sdr May 28 01:10:58 Don't know about this SDR, but at the RF symbol correlation level, some previous projects have been "coded" in Verilog or VHDL, being based on FPGAs. May 28 01:10:59 the hardware is basically just a fast ADC/DAC and host interface May 28 01:11:19 i'm wondering how much can be offloaded to the host, can the host really respond fast enough after doing the dsp? May 28 01:11:21 this one uses an NXP ARM May 28 01:11:26 Oh, not clever hardware then. May 28 01:11:28 fiola, Gerry what her name has done that May 28 01:11:33 for the onboard processor May 28 01:11:38 Yeah, jeri May 28 01:11:42 the chick fro moregon May 28 01:11:45 they are making another with usb3.0 and FPGA May 28 01:11:52 jeri, ok lol May 28 01:12:08 hackRF is meant to use the host computer for the processing May 28 01:12:30 fiola: so basically for those sdrs, the rtl bit stream would be shipped to the sdr's own fpga for the processing? May 28 01:12:36 hmm May 28 01:12:37 mastiff: sounds like a job for a PRU !! May 28 01:12:38 hah May 28 01:12:48 expensive hw for free, really? May 28 01:12:54 :) May 28 01:12:58 new project ? SDR_PRU ? May 28 01:13:05 joel_: yes. The CPUs just did high level (slow) stuff May 28 01:13:07 PPRU_SDR <---- May 28 01:13:09 do they ship here May 28 01:13:33 fiola: interesting May 28 01:13:41 if its darpa id have to assume its US only May 28 01:13:56 no It's not US only May 28 01:14:06 Don't forget the country if you are not in the US. I don't know how to format non-US addresses without your help. May 28 01:14:11 interesting May 28 01:14:42 I'm interested in using Hack RF with the BBB and this BCC http://ebrombaugh.studionebula.com/embedded/bcc/index.html May 28 01:14:47 however the item count seems so low that requests will be like 100 times over May 28 01:14:51 ? May 28 01:14:56 it got extended though May 28 01:15:17 doubt that would have happened if it was oversubscribed May 28 01:15:27 http://www.youtube.com/watch?v=YFVgq3ZB0Mo&list=PL46F6F1E70135FDA3&index=1 May 28 01:15:33 Jeri's my hero May 28 01:16:30 These are the HackRF guys https://www.youtube.com/watch?v=g070WBv1ly0 May 28 01:16:59 her PCB doesn't look so hot for RF May 28 01:17:19 fiola, she sure seems to have from with repurposing stuff. but myself i like the jonathon coultran stuff they were workign on May 28 01:17:31 seems t ohave fun with* May 28 01:18:00 the "code monkey guitar" May 28 01:18:08 i thought that stuff was awesome May 28 01:19:07 Well, reflowed my SD card cape and my bbb hasn't exploded. May 28 01:19:20 lol May 28 01:19:21 so that's a good sign. May 28 01:19:24 so there is really free lunch? May 28 01:19:24 is that a bad thing ? May 28 01:19:39 free lunch on us gov money? :) May 28 01:19:41 hahaha May 28 01:19:47 aren't they broke there May 28 01:20:00 ketas, soudns suspicously like food stamps . . . May 28 01:20:15 well, actually there can be educational benefit May 28 01:20:28 * m_billybob nods May 28 01:20:56 ketas I was jus tplayign on words ---> [18:19] free lunch on us gov money? :) May 28 01:21:06 its known as food stamps ;) May 28 01:21:17 Is there a way to flash a cape EEPROM on i2c2? Or does it have to be hotwired into I2C1? May 28 01:21:24 which is also why some companies will send you limited amount of free samples of their chips May 28 01:21:34 tax writeoff May 28 01:21:35 so how do I unbrick my BBBs? May 28 01:21:51 caress boot button May 28 01:21:52 mastiff, you could always do these steps for debian . .. May 28 01:22:00 yeah that sound goo May 28 01:22:02 good May 28 01:22:11 the debian May 28 01:22:17 not garunteed to work, but what is it going to hurt . . . May 28 01:22:23 given up on carressing May 28 01:22:26 mastiff: insert microsd, hold down boot, apply power? May 28 01:22:29 btw May 28 01:22:43 what kind of io port protection i need for that soc May 28 01:22:59 ketas, wtf is up with that anyhow ? I dont have to hold down S2 on my board. May 28 01:23:06 even human body equivalent of esd can damage it? May 28 01:23:08 never have May 28 01:23:17 those steps are in the SRM May 28 01:23:22 boot? you mean reset? May 28 01:23:29 mastiff: no May 28 01:23:32 boot button May 28 01:23:49 mastiff: Well the great thing about Jeri is that she's self-made and so totally fearless. I doubt she's ever taken a course in transmission theory or microwave layout, but that doesn't stop her, because she has EE commonsense on her side. Just awesome. May 28 01:24:02 mastiff: there is three buttons on board May 28 01:24:06 i see power and reset by the eth, and another on the other sie May 28 01:24:08 side May 28 01:24:09 s/is/are/ May 28 01:24:22 yes, boot button is on the other side of board May 28 01:24:25 fiola, my understanding is that sheis self taught from a young age May 28 01:24:32 ! May 28 01:24:55 e.g. used to tear stuff apart A LOT make stuff from junk yard stuff, etc May 28 01:25:02 aren't there already lot of large pictures about hw May 28 01:25:05 with arrows and stuff May 28 01:25:33 mastiff: I come from the opposite end in EE academia, but I *wish* my students had anywhere near her skill or EE commonsense. It's a rare quality. May 28 01:25:34 could be I missed the distinction between boot and reset button May 28 01:26:42 hmm, interesting board indeed May 28 01:27:03 it even has power management a'la pc May 28 01:27:05 no leds lit except the 5v May 28 01:27:20 so did it boot? May 28 01:27:28 no May 28 01:27:37 i wish there is boot dipswitch... May 28 01:27:39 mastiff do you notice usr leds briefly lighting up ? May 28 01:28:00 windows tried to recognize it May 28 01:28:07 should be somethign like 1,2,3 May 28 01:28:11 the noff May 28 01:28:12 i could also boot back into ubuntu May 28 01:28:14 then off* May 28 01:28:41 didnt come up as a mass storage device ? May 28 01:28:44 no May 28 01:28:55 network is not connected? May 28 01:28:58 usb power ? May 28 01:29:10 but it's making noise like the cable is being connected and disconnected May 28 01:29:29 check connection then if that doesnt work try a diffferent cable if yo uhave one May 28 01:29:40 just started that after powering on with the SD installed and the boot button held down May 28 01:29:42 hmm May 28 01:29:46 bootlooping? May 28 01:29:48 ill try another cable and port May 28 01:29:52 just in case.... May 28 01:30:06 oh right mastiff, do you know which is the root hub port ? May 28 01:30:24 thats a semi common problem from within windows and USB embedded devices May 28 01:30:27 not sure how to check that on windows, device manager? May 28 01:30:36 yes May 28 01:30:50 30 May 28 01:31:08 oops, that was my daily forget to type /w, sorry. May 28 01:31:10 how did you even break it May 28 01:31:18 and it should be very easy to fix May 28 01:31:18 usr 3 led staying lit May 28 01:32:13 broke 2 BBB by flashing a 16 GB sandisk SD according to Getting Started instructions and trying to boot off the SD May 28 01:32:16 mastiff could even try trial and error you should know whcih port it is, when it comes up as a mass storage device. assuming it does May 28 01:32:33 it was recognized out of the box, but not now May 28 01:32:40 same port ? May 28 01:33:04 well heh i guess having a workign OS on the bbb would help there. May 28 01:33:06 i could SSH in from puttty in windows, or in ubuntu May 28 01:33:17 out of the box, but not now May 28 01:33:40 you have a ttl serial 3v3 module ? May 28 01:33:55 after compiling rtl-sdr, I started compiling gnuradio and ran out of room so I tried to flash the 16GB SD and boot off that May 28 01:34:14 i have an Uno32 May 28 01:34:25 that has 3.3 digital outs May 28 01:34:43 I think my arduinos are all 5V May 28 01:34:52 Both my BBBs are Fed May 28 01:34:54 well if you could somehow hack a USB<->serial link out of that somehow. May 28 01:35:15 also have a MSP430 May 28 01:35:20 it's pretty hard to actually brick a beagle without shorting it May 28 01:35:23 i think you can from that May 28 01:35:26 you could read whats going on at boot from the serial May 28 01:35:27 i didn't short it May 28 01:35:31 not sure what is up May 28 01:35:42 bleh 3km^2 in 2hrs...not good. May 28 01:35:48 then it's probably not bricked... reflash it May 28 01:36:00 also the 7-zip extracted .img was 3.5GB is that right? May 28 01:36:08 thurgood hes done that like twice already today maybe more lol May 28 01:36:42 maybe reflash with a different .img May 28 01:36:57 somehow the flashed SD fucked two different BBBs May 28 01:37:13 3.8.11 is that the current ? May 28 01:37:16 mastiff, I've heard this story before. May 28 01:37:18 both were working fine before trying to boot off the flashed SD May 28 01:37:21 dunno why yet. May 28 01:37:29 yes the current from the Getting Started May 28 01:37:31 I need more information. May 28 01:37:56 I can do whatever you need on this end.... May 28 01:38:13 mastiff, if you keep gettign stuck in this "loop" you're goign ot need a serial cable. May 28 01:38:20 mastiff, serial console May 28 01:38:31 a debugging cable? May 28 01:38:34 capture what is happening on bootup May 28 01:38:53 soething like an FTDI to USB without any level shifters May 28 01:38:57 3v3 May 28 01:38:58 sec May 28 01:38:59 I probably can use some of the hardware I have to do that, just need to figure out the easiest way May 28 01:39:11 Can I use my logic analyzer for that on my scope? May 28 01:39:18 It has spi and i2c trigger. May 28 01:39:20 okay I'll let you sort that...right now we are flying blind. May 28 01:39:26 have only used it for analog before..... May 28 01:39:43 I need you to tell me what the console is spitting out May 28 01:39:49 that will tell the story. May 28 01:40:01 someone confirm May 28 01:40:03 http://www.adafruit.com/products/70 May 28 01:40:10 i think thats what you need mastiff May 28 01:41:01 adafruits "information: leaves somethign to be desired May 28 01:41:03 m_billybob, maybe...maybe not May 28 01:41:15 depends on how its laid out May 28 01:41:24 ok, yeah I can make that within the hour I think. Just need to splice the female pin connectors onto usb cable in the right color config. May 28 01:41:51 this is a serial port device like an FTDI or PL2303 without level shifting May 28 01:41:53 need to find a doc with the right pinout May 28 01:41:56 think Bus Pirate. May 28 01:42:33 Yeah, understand the concept, just don't have anything setup right now May 28 01:43:00 np...I have to go serve the Santa Maria Tri Tip..its 160F and ready to go. May 28 01:43:03 bb1hr May 28 01:43:04 http://www.adafruit.com/products/954 May 28 01:43:08 thats what the ysuggest May 28 01:43:24 half price by comparrison but its not FTDI May 28 01:45:07 nothing more than soldering the female pin connectors to a USB cable right? May 28 01:45:24 no you need a 3v3 ttl serial module May 28 01:46:03 usually they come with USB on one end and pin4-6 pinout on the other May 28 01:46:35 is that for shifting from 5 to 3,3v May 28 01:47:05 again im not an EE, best I can describe it though, is that its a USB to UART converter May 28 01:47:12 basically a COM port emulator May 28 01:47:49 ( over USB ) May 28 01:48:30 I'm just trying to figure out if I can make something tonight or if I 'll have to order something..... May 28 01:48:47 Maybe fastest to send the BBBs back to digikey May 28 01:48:57 how wel do you know the msp430 launchpad ? May 28 01:49:22 not well because I liked the Uno32 alot better and used that May 28 01:49:43 i dotn know the uno32 at all May 28 01:50:09 was jus ttryign to think of a way to describe the hardware ( USB to serial ) in better terms you might understand May 28 01:51:02 Hello everyone May 28 01:51:02 I have both the launchpad and additional msp430 dip chips May 28 01:51:02 I am new to beaglebone and I have a few questions May 28 01:51:02 pretty sure there are tutorials out there for msp430 based debugging May 28 01:51:45 I know it is possible to use USCI_A on a msp430G2553 as UART, and you could connect that to the serial pns on the bbb but not sure exactly what software you would need. Possibly you could get away with echoing the RX buffer to TX out over serial but . . .hmmm May 28 01:52:00 Hi Guys May 28 01:52:09 Is their Android available for BeagleBoard Black? May 28 01:52:11 Hi May 28 01:52:14 Yes May 28 01:52:35 well dang, I ran into a snag. even though the BB white doesn't have any kind of video output, is it possible to open up a local terminal screen upon boot? I'm trying to have it auto-login so that I can type stuff on a USB keyboard even though I can't see what I'm typing May 28 01:52:49 Mastiff May 28 01:52:50 Thanks May 28 01:52:56 But I can't find a link for android image May 28 01:53:03 I can only find it for Beaglebone May 28 01:53:04 not the black May 28 01:53:07 hi May 28 01:53:30 try TIs home page for sitara May 28 01:53:30 The same image may work, not sure. May 28 01:54:05 TI has had a workign android for sitara for hmm dont know a while. not sure it wil support teh bbb May 28 01:54:25 I will try loading it May 28 01:54:26 Thanks May 28 01:54:49 Time to give 3.10-rc3 a spin on BBB May 28 01:54:52 I think their site advertises that its for BBB May 28 01:56:04 mastiff ---> http://eewiki.net/display/linuxonarm/BeagleBone+Black Just somethign to consider. if yo uhave a debian /ubuntu box you can setup as a cross development envoirnment that may work for you at least short term May 28 01:56:33 i know the debian setup instructions work ive done them myself a few times May 28 01:56:58 someone i know did the rootfs for ubuntu too and told me it worked May 28 01:57:30 Yeah I'll give it a shot, have been working on BBB since early AM May 28 01:57:59 had successes and then big setbacks May 28 01:58:33 you have fast internet ? i have 1.5Mbit DSL, took me around 4-5 hours including download times. afterwards only takes about up to 30 minutes May 28 01:58:52 once you've compiled everyting May 28 01:59:14 playing sitara hmm May 28 02:00:45 mastiff, but you know the more i think about it the more it soudns like a flaky piece of hardware or accessory May 28 02:01:12 USB cable, bad SDcard or something. and hmm uSD have a readonly siwtch on them ? May 28 02:01:15 lol ive never looked May 28 02:03:01 most liekly windows would let you know if you had the readonly switch turned on, if they do have them May 28 02:05:08 yeah I mean i was able to figure out the the rtl-sdr comile issue and get that working May 28 02:05:33 so it went from working, then you turned it off then came back and it failed ? May 28 02:06:08 but when I tried to flash the updated angstrom linux image onto my SD, booting off that borked both my BBBs and the won't boot at all May 28 02:06:57 i ran out of space on the 2gb interal when compiling gnu radio, so was trying to boot off a 16gb SD May 28 02:07:33 before reflashing the SD, windows recognized both BBBs, now neither, with or without the SD installed May 28 02:07:37 well using those steps for debian work, and will boot from sd even. so if you have morethan one sd card, or use one to install one thing on the emmc, then another on the sd card you can effectively dual boot May 28 02:07:40 ah yeah May 28 02:07:47 m_billybob, roberts wiki is great May 28 02:07:56 i know i love it May 28 02:08:08 i'll try the debian instructions May 28 02:08:09 mastiff mrpackethead installed debian too on his May 28 02:08:25 yes, its nice and stable May 28 02:08:36 sounds better for tonight anyways than trying to debug serial May 28 02:08:49 mrpackethead i ran my bbb on debian aty full CPU load (99.5%) for abotu an hour earlier no isses May 28 02:09:04 this will let us set up things easily May 28 02:09:05 after an uptime of 6 days May 28 02:09:22 i dont' think there is a netinstaller yet May 28 02:09:29 but thats not so much of a problem May 28 02:09:35 if we can custom build our install May 28 02:09:38 in fact that better May 28 02:09:48 im probably goign to write a simple libc app tonight to give the user the ability to load the CPU at a certain % May 28 02:10:00 well to give myself May 28 02:10:35 might toss the code out there for someone to use if they want but its simple so anyone familiar with C could probably do the same in a short period of time May 28 02:11:04 possibly even better than me since im still very new to linux development May 28 02:12:00 mrpackethead, yes, download / build once, write millions of time if yo uwant May 28 02:12:22 ive written this build 4 times so far May 28 02:12:30 to different uSD cards May 28 02:12:44 Ok, I'm going to go plug my laptop and BBB into ethernet and try that debian install, will check back with you guys shortly May 28 02:13:10 mastiff, ifunsure of anything or have a quesiton just ask May 28 02:13:54 LOL Rev A5B: 2) Made the LEDs dimmer for those that could not sleep due to the brightness of the LEDs. May 28 02:14:18 Shadyman mine stay runign in my bed room while i sleep all night lol May 28 02:14:22 yeah, i'll follow those instructions and check back if anything doesn't proceed correctly May 28 02:14:23 stays* May 28 02:14:32 m_billybob: You poor thing. May 28 02:14:44 i put it behind my laptop lol May 28 02:15:07 but i imagine if i sat up all night just staring at the thing it'd bother me too lol May 28 02:15:19 sometimes i wake up feelign like theres a cop car in my roo mthough hahaha May 28 02:18:14 Dammit. May 28 02:18:41 * Shadyman designs an SD Cape and the BBB uses those pins for emmc May 28 02:18:43 * Shadyman squints. May 28 02:18:56 eeps May 28 02:19:13 run the bbb off of sd ;) May 28 02:19:28 ^ May 28 02:19:30 That. May 28 02:21:41 Though, the onboard MMC is pretty fast. May 28 02:22:51 http://pastebin.com/YUgxXHhm May 28 02:23:40 but it IS kinda small. May 28 02:25:37 actually, I re-ran the test 2 more times on each, the cached reads from microsd actually went up to 196 average May 28 02:25:57 cached reads aren't actually touching the card, are they? May 28 02:26:44 dont thikn so May 28 02:27:01 what brand is that card? in a dedicated card reader I can get 16-20MB/s from a SanDisk 32GB uSD May 28 02:27:11 ^ That. May 28 02:27:12 the eMMC has the advantage of having double the bus width (8-bit vs 4-bit) May 28 02:27:35 sandisk 16gb class 10/ uhs class 1 May 28 02:28:04 I'm tempted to say linux might not be turning around bus transactions very fast... May 28 02:28:12 er, bus interrupts May 28 02:30:14 has anyone written a script or php page or something to generate cape EEPROM .bins? May 28 02:32:35 wouldnt that be nice May 28 02:33:45 or heck, even a spreadsheet :/ May 28 02:34:56 just had an evil thought May 28 02:35:10 silly evil thought but evil none the less May 28 02:35:25 mark uSD RO and use the emmc as a swap heh May 28 02:35:40 * m_billybob wanders off in shame May 28 02:38:38 Shadyman, whatchu tryin ter do? May 28 02:42:10 i've got an sd card cape now, just trying to make it do things. May 28 02:42:44 and why do I suspect that it conflicts with the eMMC... May 28 02:44:50 it uses the same pins? May 28 02:44:51 and doesn't have a chip select May 28 02:45:42 means I get to hold the emmc down in reset :/ May 28 02:54:55 Shadyman, there is a fix for this and a GPIO that holds it in reset **** ENDING LOGGING AT Tue May 28 02:59:59 2013
