**** BEGIN LOGGING AT Fri Sep 19 03:00:00 2014 Sep 19 03:05:51 thurgood thus is life in irc. according to nickserv I have been idling on free node off and on now for 13 years 20 weeks 4.5 days :-) Sep 19 03:08:35 heh, this is true but some people get bent out of shape when they don't get quick answers Sep 19 03:09:05 nah? not me :-) Sep 19 03:09:27 my only hold back so far is it looks like the bob does 3.3v pwm :-( Sep 19 03:10:08 what do you do with your bob? Sep 19 03:11:13 not much, we never moved to the bbb design due to limitations with the color depth and lack of gles support Sep 19 03:11:28 we still use 3730 based boards Sep 19 03:12:55 ah Sep 19 03:20:07 If I am reading this correct it looks like the ldd might work with the 3.3v Sep 19 04:04:29 sweet, Ordered :-D Sep 19 04:04:34 this should be fun... Sep 19 04:24:12 good night :-) Sep 19 06:53:31 hello, can someone tell me where is the latest kernel source for bbb to download! Sep 19 06:54:14 compiled or source? Sep 19 06:54:18 ah sorry Sep 19 06:54:20 source Sep 19 06:54:32 there are many Sep 19 06:54:40 there is no "one" kernel Sep 19 06:54:51 https://github.com/beagleboard/linux Sep 19 06:55:01 tbr there is only one Sep 19 06:55:06 vanilla from kernel.org would work too Sep 19 06:55:08 *g* Sep 19 06:56:12 i mean why beagleboard.com doesnt mention standard kernel for beaglebone's Sep 19 06:56:43 what standard kernel? Sep 19 06:56:49 which of them? Sep 19 06:56:50 what is a standard kernel? Sep 19 06:58:42 i saw some where rcn, and some other kernel patches and other kernels too, but shouldn't beaglebone provide the official kernel patches for e.g BBB? Sep 19 06:59:24 milad you can read nor? Sep 19 06:59:48 https://github.com/beagleboard/linux -> The official BeagleBoard and BeagleBone kernel repository Sep 19 07:01:04 woglinde: if i use this one and standard debian rootfs is it compatible? Sep 19 07:05:41 sure Sep 19 07:06:05 the times of incombatiple udev or stuff are offer for some time Sep 19 08:32:08 hi! Sep 19 08:36:07 hi rotti Sep 19 08:48:02 hi woglinde Sep 19 08:49:38 hi hitlin Sep 19 09:09:29 Hi there! I am trying to enable the DCAN1 interface at boottime by adding capemgr.extra-override=BB-DCAN1 to my uEnv.txt. But after a shutdown/power-on my Beaglebone Black doesn't reboot. It just switches all LEDs on. If I do echo BB-DCAN1 > /sys/devices/bone_capemgr.*/slots everything works fine. Sep 19 09:13:54 morph why not make a sysvinit/systemd/upstart script which does the echo? Sep 19 09:15:05 woglinde, because I thought the capemgr-option would be the nicer way. Isn't it? Sep 19 09:15:15 depends Sep 19 09:15:26 or look at the serial output what's going wrong Sep 19 09:17:07 tbr, how do I do that? After the change my BBB isn't detected at all on my Win7 machine that is connected via mini-USB Sep 19 09:17:27 attach to the debug serial port Sep 19 09:17:35 FTDI cables are cheap Sep 19 09:17:46 if your uni lab doesn't have one Sep 19 09:18:16 tbr, ok, but then I first had to buy one, that takes some time... But thanks for that hint anyway! Sep 19 09:18:37 ask around your lab first? Sep 19 09:18:45 woglinde, I will have a look at it. Do you know about example code in the wiki or elsewhere? Sep 19 09:19:21 tbr, I know that we don't own such a cable Sep 19 09:20:14 or if you have a second board you could even use that. :) Sep 19 09:20:41 morph: a max3232 would work in combination with a "real" rs232 port, too Sep 19 09:21:44 tbr, I do :) You mean as a test board, or to connect it as a debug device? Sep 19 09:21:44 morph: ftdi chips (or pl2303[?]) are often used in gps mice, too... maybe you can find something like that Sep 19 09:22:45 ...or use a uart from another bbone. just connect rx/tx and run screen, minicom, ... Sep 19 09:26:02 thanks guys! I will do some research on that topic. Just to get to know a bit more about the issue in general: I mean it is quite a general case that you want to activate capes/hardware on every startup. Thus, I won't be the first one doing this. Is there a general (proven) way in doing it? How do you do it for instance? Sep 19 09:29:31 iirc i used echo, too... but it's a year ago since i last worked with that :( Sep 19 09:31:35 ok, I would prefer to do things only once to end up with a well configured system that just boots up and works Sep 19 09:31:58 it did... `echo ...` was in /etc/rc.local ;) Sep 19 09:32:46 nice! i didn't know that is working too. Then this would probably also a good place to load the drivers with modprobe etc. Sep 19 09:32:56 don't know what's the problem with your setup (log messages from serial console might help), but maybe you have to initialize it later... Sep 19 09:33:27 i guess you have to attach a can transceiver, right? Sep 19 09:33:39 yes, probably that might be. Sep 19 09:33:49 indeed, I attach a can transceiver Sep 19 09:34:18 iirc, there was this stuff with "plug'n'play". can't you just put an eeprom to the board, too? Sep 19 09:34:18 since I don't use the can cape. Instead I use the raw output with a can transceiver Sep 19 09:34:54 in this eeprom, you can tell what should be loaded etc Sep 19 09:35:19 (i tried it for my own cape, but didn't get it to work.... but it might have been some other problem) Sep 19 09:36:04 ok, nice hint. thank you! we are also looking forward to designing our own cape one day. Sep 19 09:49:49 Rotti, I'll do it with rc.local since it worked fine. Thank you! Sep 19 10:12:07 morph hehe yes rc.local the poor mans choice Sep 19 10:18:11 woglinde, hehe, time is money Sep 19 13:23:33 <[g2]> whois rwhitby Sep 19 13:26:08 not me Sep 19 14:30:51 . Sep 19 14:59:16 I'm running around trying to find how to create a bootable SD from OS X... anyone have a lead? Sep 19 14:59:37 neufuture: osx should have dd too Sep 19 15:01:11 or use vagrant passthrough the sdcard device Sep 19 15:01:45 ok I guess I could try dd route, but was hoping to just copy the files. Sep 19 15:02:23 not sure what vagrant passthrough is Sep 19 15:02:46 vagrant is a management tool for virtual vms Sep 19 15:02:53 which can use virtualbox Sep 19 15:04:26 ok will take a lok Sep 19 15:04:53 you need to write a small vagrant file Sep 19 15:05:21 and than depending on your inet connection you setup a linux vm in 10 minutes Sep 19 15:05:24 +can **** BEGIN LOGGING AT Fri Sep 19 15:42:01 2014 Sep 19 15:42:19 I've come down to 2 possibilities : Sep 19 15:43:22 1st, I do not have the FTDI cable that seems mandatory Sep 19 15:43:50 2nd, I'm booting from a created SD card, but i didn't flash it onto the eMMC Sep 19 15:44:09 could one of those things cause the problem ? Sep 19 15:44:20 thank you for your answers :) Sep 19 15:46:45 Hi, is there a debian for beaglebone without all the extra guff, just pure debian which still has all the gpio and leds stuff? Sep 19 15:58:29 Mustek do not think so, but you can make your own by deinstalling all the unwanted stuff Sep 19 15:59:16 And risk to accidentally something Sep 19 16:38:07 anybody have any good resources for somebody wanting to build a pcb for the beaglebone black? I know adafruit has a fritzing part for the beaglebone black. I have a double sided pcb from radioshack and etching solution and would like to make a cape for my beaglebone black. Sep 19 16:45:07 mistawright: well, first you have to decide on what is it supposed to be doing Sep 19 17:59:26 Mustek: Look for the console version Sep 19 18:00:24 I will Sep 19 18:00:27 is it flashable? Sep 19 18:02:27 Yes Sep 19 18:02:59 http://www.elinux.org/BeagleBoardDebian#eMMC:_BeagleBone_Black Sep 19 18:03:11 under Get Prebuilt Image Sep 19 18:05:55 spe: And it certainly has the gpio/leds stuff? Sep 19 18:06:09 Because that heartbeat makes me lose my sleep :p Sep 19 18:06:33 Mustek: I'm not sure what you mean by LEDs and GPIO stuff. Sep 19 18:07:02 But yes, you have this magic /sys/gpio stuff where you can control gpios. Sep 19 18:07:04 to be able to control them Sep 19 18:07:12 good, thanks Sep 19 18:07:17 Will look into later. Sep 19 18:07:22 OK Sep 19 18:07:57 This blue led light is quite sharp yes, but I put it in my kitchen instead ;) Sep 19 18:08:11 I have no ethernet running into my kitchen Sep 19 18:09:10 spe: Embest board as well? Sep 19 18:09:20 tape over the leds? Sep 19 18:09:34 nah, echo none into the usrled Sep 19 18:09:35 Mustek: No beaglebone black... Sep 19 18:15:52 I have a challenge; managed to compile a kernel and run it from SD incl. rootfs. Copied all generated files to eMMC. Now eMMC wants to have rootfs on SD despite I only changed kernel, dtbs and modules. Sep 19 18:16:06 I have a working Debian system in the eMMC originally. Sep 19 19:03:10 I'm having some trouble getting ethernet over USB to work. I have the g_multi module loaded at boot and usb0 assigned an IP address. What else is needed? Sep 19 19:08:35 Hi all - are there any size limits on the memories that can be attached to the SDCard or SPI interfaces? I can't think of a HW reason why there'd be a limit. Sep 19 19:11:31 mayormccheese2k, well the mmc controller can only do sd/sdhc so your stuck with 32GB max native.. sdxc extended that, but the hardware doesn't support natively... Sep 19 19:17:01 Thanks rcn-ee! Sep 19 20:37:17 hi Sep 19 20:51:28 how do i read the analog inputs on a beaglebone black rev. c under debian 3.8.13-bone64? Sep 19 20:51:37 Carefully. Sep 19 20:51:41 i've tried every google hit i've found with no luck Sep 19 20:52:09 except the pru method, which i'm trying to avoid to save time, and i don't need to read them that fast anyway Sep 19 20:52:22 agmlego: eschew obfuscation. Sep 19 20:53:08 I would think that would be a thing exposed in sysfs. Sep 19 20:54:41 yeah, i need about two levels more specific knowledbe that that, agmlego Sep 19 20:55:57 Well, I lack it, so try the TRM/SRM, or the kernel source, or the Device Tree/sysfs stuff, or... Sep 19 20:56:12 Or wait for someone with more knowledge than I to take interest in your plight. ;-P Sep 19 21:00:36 rcn-ee: do you have any recommendations? Sep 19 21:04:27 you need to load the iio overlay.. Sep 19 21:05:35 echo cape-bone-iio > /sys/devices/bone_capemgr.9/slots Sep 19 21:05:36 ? Sep 19 21:05:46 as root: echo cape-bone-iio > /sys/devices/bone_capemgr.*/slots Sep 19 21:08:43 right, i've done that, but find /sys/ -name "*AIN*" finds nothing Sep 19 21:10:30 dmesg shows it loaded correctly Sep 19 21:15:17 do you have to echo something to /sys/bug/platform/drivers/bone-iio-helper/bind? Sep 19 21:15:27 s/bug/bus/ Sep 19 21:19:54 rcn-ee: ? Sep 19 21:20:40 find /sys/ -name '*AIN*' Sep 19 21:21:39 right - i did that (as i said) - nothing. Sep 19 21:22:05 i did it again using your exact syntax, results were the same. Sep 19 21:22:47 i even tried using "iname" instead of "name" - picked up a few things but they weren't ain's Sep 19 21:22:58 or wait.. it's /sys/bus/iio/devices/iio:device0/ Sep 19 21:24:08 beautiful! thanks rcn Sep 19 21:24:33 forgot we had a gsoc, get that mainline and backported the iio stuff.. Sep 19 21:25:52 well, i sure appreciate the magic spells - without them i'd be hosed. Sep 19 21:39:06 rcn-ee, quick question. the 3.8.x tree, the universal-io from charles is forever set in stone, or does it change too along with the 3.14.x branch ? Sep 19 21:39:51 well m_billybob, we are using charles's universal-io as a basis for v3.14.x... Sep 19 21:40:14 no overlays, everything is going to be done thru universal-io... Sep 19 21:40:29 so its not really a package type thing in 3.8.x but more of git thing ? Sep 19 21:41:01 it's a userspace thingy Sep 19 21:41:17 im really interreted in 3.14.x but want it to settle some before i obligate myself to it. One thing im noticing too on the later 3.8.x kernel version image. they seem slower Sep 19 21:42:14 boot times with systemd are definately twice as fast atleast but there seems to be some comdline "lag" not sure how to explain it Sep 19 21:42:17 i don't see why that would be.. the last few v3.8.x tag's has been fixes only.. Sep 19 21:42:22 some tools / apps do not seem to work as fast Sep 19 21:42:32 maybe its my imagination. Sep 19 21:43:00 might be... we all get use to it being "fast", then it's slow again... Sep 19 21:43:17 however using backports for systemd i did end up screwing myself. it messed up something( i forget what exactly i should have documented it ) Sep 19 21:43:18 we could disable systemd for a release, get everyone use to the 45second bootup times again. .;) Sep 19 21:43:51 humm. i haven't really tested jessie/systemd bootup time, so i can't compare yet.. Sep 19 21:44:08 that never happens to me perhaps because I always use /etc/network/interfaces, and I have a serious adversion to wicd and all that network manager stuff Sep 19 21:44:49 i dont like tools that think they're smarter than me Sep 19 21:44:59 don't worry, wicd won't be used in jessie... i'm going to give conman one more shot.. otherwise, i'm just going to script "sudo dhclient eth0" instead.. Sep 19 21:45:51 unless we find a way to not tie up "login" behind waiting for eth0 (that's why eth0 is not in /etc/network/interfaces by default) Sep 19 21:45:56 Ive also read somewhere, if you mix SYSV type init scripts with systemd ( sysctl is it ? ) services you can slow your system down some at boot andotherwise Sep 19 21:46:51 i don't think it matters, angstrom was systemd only, had 10ish bootimes, wheezy is a mix, around 11ish.. Sep 19 21:47:17 I'd be very interrested in trying to get an Lubuntu install working. I'm very impressed with Lbuntu on a desktop PC. first time for me being impressed with Ubuntu anything in years Sep 19 21:47:53 i get ~15-16s boots with systemd on wheezy cant say with the regular init daemon. no way to test really aside from using a stopwatch Sep 19 21:48:02 that's why used 'lxde' as the default wm... i'm looking at using lxqt for jessie.. Sep 19 21:48:24 systemd-analyze Sep 19 21:48:31 with i knew more about building al this stuff id try to help Sep 19 21:48:35 wish i knew more* Sep 19 21:49:03 You build system is based on buildroot ? Sep 19 21:49:11 based debootstrap.. Sep 19 21:49:44 yeah ok i know what it is what it does just dont know how to use it yet. ill get there soonish hopefully, and i need to understand git better. Sep 19 21:50:39 it's just a tool to create an initial debian rootfs from the debian repo's.. Sep 19 21:50:56 Could you suggest reading material or something otherwise that i could start cutting my teath on even if private until i get better at it ? Sep 19 21:51:32 i know a lot of this is just dop until you get enough experience to do wel at it. like anythign linux lol Sep 19 21:51:50 i just read google, hack and slash on a something till it works, because i know it works on x86. ;) Sep 19 21:52:25 ok cool i get that Sep 19 21:52:33 virtual box has its uses ;) Sep 19 21:53:19 i do not like mesing with my pristine realy machine installs but have no qualms "destroying" a virtual machine Sep 19 21:53:42 nah a arm farm helps, with backup serial access over network along with a network power relay box.. ;) Sep 19 21:54:02 yeah i do not have the resources you havethough lol would be nice though :) Sep 19 21:54:42 it started with one beagle board 6 years ago... then i just kept on buliding managment hardware around it.. Sep 19 21:55:12 I can kind of experiment and do with my bbb NFS rootfs helps a lot. screw it up ? who cares right ? just rm-rf ~/rootfs and tar a pristine image back over Sep 19 21:56:00 Then you end up with something like: https://plus.google.com/106813818225399872098/posts/gH6T3cPXcN9?pid=6042386556238314050&oid=106813818225399872098 Sep 19 21:56:09 now working on a box with a15's to replace it.. Sep 19 21:56:12 heh sometimes i wish i could borrow someone elses brain for a few minutes Sep 19 21:56:59 is that somethign akin to beowulf ? Sep 19 21:57:19 *a beowulf setup* Sep 19 21:57:41 nah, they aren't that interconnected... Just 6 boards, all running a base os's with lots of chroot's for every distro.. Sep 19 21:59:11 Do you use any rPI's in your farm ? or just all v7 stuff ? Sep 19 22:00:32 One thing i have interrest in is mame, and i think in order to build something that I want ill have to break down and get an rPI eventually Sep 19 22:00:47 just v7, i'm still running an old beagleboard c4, for kernel stabilty tests.. i don't push it like i use too, just too slow at 600Mhz.. Sep 19 22:01:50 Oh one more thing i was curious about. Will SGX always be fb based or will it eventually have ogl support ? Sep 19 22:02:30 Stil not sure the SGX thats currently on board will have enough gfx horsepower to do what I want with mame. eventually. Sep 19 22:03:20 the only hope, is egl.. (wayland/android).. we use to have x11 render support, so you could run the sgx demos in a x11 window, but disapeared in 2.6.38 timeframe.. Sep 19 22:04:31 Yeah, it was just a fleeting thought anyhow. imo not really what the BBB was intended for anyhow. Sep 19 22:05:04 the sgx core was put in there for android use cases's.. Sep 19 22:05:18 Maybe odroid, but i dont know much about that hardware yet Sep 19 22:06:15 odroid is ok, but some core features are still missing from their android branch... like bluetooth Sep 19 22:06:25 we just need someone to figure out the egl/wayland bits... Sep 19 22:07:27 rcn-ee, yeah i dont know much about that hardware. ive been constantly learning since we first got our two BBB's last year. hardly pulling my head out of the sand so to speak Sep 19 22:07:37 err dont know much about that software* Sep 19 22:07:45 egl wayland etc Sep 19 22:08:14 my view is that the BBB was meant to run cmdline only via ssh with semi headless Sep 19 22:08:22 or in my own case 100% headless Sep 19 22:09:39 I really liek the hardware, perfect you remote control applications Sep 19 22:10:00 perfect for* dahm i cant type today, or ever lol Sep 19 22:58:31 anyone ... what type of small camera is suitable (or unsuitable) for beaglebone black? Sep 19 23:32:06 rick01, loaded question but typically you'll need one that offloads codec manipolation if you need such a feature Sep 19 23:32:12 also one thats self powered Sep 19 23:45:20 Thanks m_billybob. sorry for my ignorance but what does "offloads codec manipolation" mefor someone new to BBB? Sep 19 23:46:39 somethign liek the logitec C920 i think it is. the camera offloads codec compression or some such. Derrek Molloy used one in his openCV video on youtube Sep 19 23:57:41 rick01: i think he means that the camera does the encoding and passes the encoded video to the bbb, rather than passing raw video and forcing the bbb to do the encoding. e.g., something like h.264 encoding. Sep 20 00:16:17 thanks guys. I don't need video, just still images. A raw matrix of pixel-bytes is what i need in the end for image processing. Which small cameras are most suited to this? Sep 20 01:01:16 rick01: that's kinda hard to answer without knowing your requirements. like saying, "which PC is best suited to computing?" Sep 20 01:01:59 you might try searching for "usb still camera" Sep 20 01:42:03 rick01, then your choces are broader Sep 20 01:42:35 you'll have to look around on the web for "beaglebone black + camera" Sep 20 01:59:57 hey m_billybob ... i already tried searching for "beaglebone black + camera". radiumboard is all i can find. Sep 20 02:00:33 i'm new to BBB so i just want to know is it easy to use any small camera with BBB? Sep 20 02:01:39 oh yes, i also found the logitech camera (too big for me) but that is all Sep 20 02:04:02 rick01, i found an aritcle a week or so ago that talked abotu two camera's by search beaglebone black + dont rememebr what it was Sep 20 02:04:18 second option the guy gave had no decode but should do stills just fine Sep 20 02:04:54 sorry i cant do any better than that, its not somethign i normally have interret in personally Sep 20 02:06:35 new to beagleboard black. i was thinking about making it into a portable gaming console. i bought a 4.3 lcd cape. is there anything else i need to do besides updating, adding drivers, ect? Sep 20 02:38:10 is it possible (and reasonable) to control the GPIO mode (pin control register) through the sysfs? Sep 20 02:38:48 s/pin control register/pad control register/ Sep 20 02:40:57 right now it appears that i must load a custom .dts with those register values set, e.g., "... pinctrl-single,pins = <0x018 0x07 ...>" Sep 20 02:42:36 on a beaglebone black rev c, debian 3.8.13-bone64 **** ENDING LOGGING AT Sat Sep 20 03:00:00 2014
