**** BEGIN LOGGING AT Thu Jul 04 02:59:59 2013 Jul 04 03:06:57 which pcb? Jul 04 03:09:57 gEDA/PCB FOSS layout app Jul 04 03:46:46 Hey emeb_mac, quick question on the BCC's CLKOUT2 connect. Is the plan to supply a 32K RTC clock to the fpga? My thought looking at that pin is to use it as GPIO0_20 and have it as a "data ready" interrupt(if/when a softcore or fpga peripheral has data to send to beaglebone) Jul 04 03:47:31 magyarm: the BCC doesn't need the CLKOUT2 to be active. That's "just in case". Jul 04 03:47:32 and question for both emeb_mac and ka6sox, do you guys have a road map of what you are looking to implement? Jul 04 03:47:56 what we're looking to implement? with what? when? Jul 04 03:48:31 whowhatwhere? Jul 04 03:48:34 emeb_mac, yes. I could probably get 32K with the DCM's Jul 04 03:48:42 with the BCC on the beaglebone Jul 04 03:49:49 I'm following along on both your github's, and was curious what your goals are with the cape and *bone. See where I can help out:) Jul 04 03:51:15 as of right now, I have gotten what you guys have posted running on mine. I have my own ideas I plan on trying to make work and share, but you guys know this better than I do, so I'd love to contribute where I can Jul 04 03:53:14 ah, okay... Jul 04 03:53:21 well.. Jul 04 03:55:17 I've got a couple of SDR-related projects in mind. I've already got that TXDAC working and I'd like to try some receiver stuff next. Jul 04 03:56:23 jmoyerman has some fixes to the DTC, I'm incorporating them now Jul 04 03:56:46 emeb_mac ka6sox, for example: I got really interested in the sort of thing th armadeus project is doing with "Peripherals on Demand". Being able to instanciate softcores and load kernel modules on an as need basis through a sole program. I've been looking at their stuff for a year or so now... and finally have hardware to do it Jul 04 03:57:27 magyarm, Software Defined Peripherals Jul 04 03:57:37 yeah, I think ssi has some interesting ideas for implementing that. Jul 04 03:57:50 ka6sox that is a good term for it Jul 04 03:59:24 magyarm, working with jon on this: https://google-melange.appspot.com/gsoc/proposal/review/google/gsoc2013/jj2baile/1 Jul 04 03:59:55 the board has a CPLD as I don't know if we can use the serializers on the PRU or not yet Jul 04 04:02:50 ka6sox interesting. I'll take a look at what he is doing. Which board has a CPLD? Jul 04 04:03:22 https://github.com/ka6sox/BoneTag Jul 04 04:09:43 ka6sox, now that's cool. Have the prus and the cpld act as a jtag programmer/debugger? Jul 04 04:10:20 the idea is to create a cape that can do programming/debugging with JTAG/SWD/SBW and AVRisp Jul 04 04:12:21 then its all Software to make it go Jul 04 04:14:34 <_av500_> HEALTHCARE!!! Jul 04 04:14:38 <_av500_> oops, wrong channel Jul 04 04:15:24 * ka6sox turns off G+ Jul 04 04:17:13 magyarm, perhaps you would like to play with one of them Jul 04 04:18:01 the idea sounds cool Jul 04 04:18:37 wow, looks like pasm is being worked on! Jul 04 04:18:38 holly crap, Jul 04 04:18:47 looking at the schematic, I don't see any reason I couldn't use jumpers to the BCC to get the same connections (minus any noise coming from wires) Jul 04 04:18:49 err...https://github.com/beagleboard/am335x_pru_package/blob/master/pru_sw/utils/pasm_source/pasmop.c Jul 04 04:19:01 i mean https://github.com/beagleboard/am335x_pru_package/tree/master/pru_sw/utils Jul 04 04:19:11 pru_evtout_2, holly christmas crap Jul 04 04:19:22 updated 2 days ago, says WIP for next version. i'm seeing opcodes that aren't in documentation. Jul 04 04:20:07 magyarm, the reason for the CPLD is to handle voltage translations and also because we didn't know when we started whether the PRU's Serializers would be usable Jul 04 04:20:10 and, multiple pasm versions! Jul 04 04:20:13 err..binaries. Jul 04 04:20:29 loader or assembler? Jul 04 04:20:53 assembler. Jul 04 04:21:18 binaries for multiple platforms. Jul 04 04:21:32 like linux, doze and maybe even mac? Jul 04 04:21:38 yes Jul 04 04:21:41 i see mac Jul 04 04:22:15 ahh wtf, there's a loop opcode! Jul 04 04:23:00 bet it saves a few ticks per loop Jul 04 04:23:07 ...i could really use that. Jul 04 04:24:00 super rad. looks like the pru might have some life left in it. Jul 04 04:26:18 why you say that? Jul 04 04:26:47 ka6sox, ok. I see. Is they a git where the current progress is right now? I will take a look and wrap my head around it. I have an idea of PRU and how it works, will have to review it again though Jul 04 04:27:19 the progress is that we are starting right now Jul 04 04:27:36 the big question is to read up on the protocols and timings Jul 04 04:28:05 (things like JTAG and TMS/TCK/TDI/TDO Jul 04 04:28:06 ) Jul 04 04:28:17 ka6sox: i've always worried that, since the pru is "unsupported" at this point, it might be removed or something. Jul 04 04:28:18 others, like SBW have differnent timings Jul 04 04:28:36 that would be a 3352 Jul 04 04:28:41 pru_evtout_2, Jul 04 04:28:43 ^^ Jul 04 04:29:18 magyarm: i know some pru stuffs maybe. Jul 04 04:29:45 pru_evtout_2, I'd hope so, it's in your name! :P Jul 04 04:30:40 ka6sox no problem. I had a look at JTAG in particular a half year or so ago for a seperate project Jul 04 04:31:26 then you and jj2baile might be able to swap notes Jul 04 04:31:28 :) Jul 04 04:33:56 ka6sox, will do some review and research starting tomorrow. It was a little while ago, and I ended up not needing to explicitely use a jtag interface... Code Composer Studio got updated for linux and the Stellaris ICDI started working Jul 04 04:34:20 won't take too long to bring it all back though Jul 04 04:35:58 magyarm, do you use SWD for the stellaris or just JTAG? Jul 04 04:36:49 used SWD. was going to use JTAG until the 5.2 update happened Jul 04 04:37:33 I was designed a board around the lm4f120 and wanted to keep things as simple as possible Jul 04 04:38:47 wait a minute... I'm lying to you. I *shamelessly* copied how the launchpad was programmed, and I assumed it was SWD Jul 04 04:40:08 but I did break out TDI, TDO, TCK, and TMS plus a handful others from my board to the stellaris launchpad to program debug Jul 04 04:41:08 truth be told, I was more worried about my AFE and it's bluetooth link. I will check my notes on what I did tomorrow. at 12:30am don't think straight Jul 04 04:52:31 magyarm, understood Jul 04 04:53:53 ka6sox, I will correct myself tomorrow, and hopefully gave an accurate representation of what I know! Jul 04 04:55:38 np...at 12:45am its not the best time to think. Jul 04 04:58:07 <[yAK]> just bought a beaglebone black are there any decent project sites or sites to help people starting to learn it? (other than the basic stuff on the beagle site?) Jul 04 05:09:54 arghblarg, Poll() stopped working when switching distros. Angstrom -> Debian 7.0. Though /gpioX/edge exists Jul 04 05:44:04 a wonderfull JIHADistic FRIDAY everyone! Jul 04 05:54:55 KotH is a day in the future. Jul 04 06:01:21 http://26-26-54.hardwarebug.org/52 Jul 04 06:41:30 Hi, I have two beaglebone, i can see the serial output at the first one, for another one , i can not see any output from serial (both use the same sd card), I do not why? Jul 04 06:42:12 how do you connect to the serial port? Jul 04 06:43:51 micro usb Jul 04 06:44:13 and which beagle bone is this? Jul 04 06:44:45 what does this mean? Jul 04 06:45:13 is it white or is it black? Jul 04 06:45:18 beagle bone includes different series? Jul 04 06:45:26 white Jul 04 06:46:47 yes, there is also a newer, black model Jul 04 06:51:29 ? Jul 04 06:52:03 I do not have beaglebone black Jul 04 06:52:28 theres a begleclone red as well Jul 04 06:53:26 from china? ;) Jul 04 06:53:42 probably. Jul 04 06:53:47 i just heard rumours of it Jul 04 06:54:19 at $0, i'd still buy the blackones Jul 04 06:54:32 Rocky: anyway, your board has a FTDI usb-to-serial chip. so yes, there is a serial port. Jul 04 06:54:38 Rocky: how are you powering the boards? Jul 04 07:04:07 good möurning trolls, djihadis ad djihadistas. Jul 04 07:04:54 good mourning to you too, your excelency Jul 04 07:05:25 * LetoThe2nd hands KotH some caffeinated spice Jul 04 07:05:47 micro usb Jul 04 07:05:56 * KotH suddenly feels very awake and aware of his suroundings Jul 04 07:06:17 micro usb supply the power for my board Jul 04 07:06:34 Rocky: mini, probably. BB has no micro. Jul 04 07:07:06 LetoThe2nd: doesnt mean you cannot plug in a micro usb power supply ;) Jul 04 07:07:27 KotH: yes, if the force is with you. Jul 04 07:07:42 LetoThe2nd: s/force/stupidity/ Jul 04 07:07:49 Ok Jul 04 07:07:51 mini Jul 04 07:08:00 it is my mistake Jul 04 07:08:01 * KotH has been in the army, and thus seen a lot Jul 04 07:08:14 and that stuff is DAU compatible Jul 04 07:08:17 ^^; Jul 04 07:10:35 hrhrhr Jul 04 07:13:01 Rocky: does your PC/mac/whatever enummerate the serial port? Jul 04 07:16:10 when I connect the good one bb to my windows PC, it will shows two COMS( COM8 and COM9), when I connect the bad one bb to my windows PC, it only shows one COM (COM10) Jul 04 07:19:14 is it possible that the code in internal ROM is corrupted? Jul 04 07:19:30 how do you figure ROM gets corrupted? Jul 04 07:19:48 unless you mean the SD or eMMC card and that most certainly isn't ROM Jul 04 07:20:21 no , I mean the internal rom Jul 04 07:20:40 the sdCARD is good, i have verified it on my another good bb Jul 04 07:21:27 I mean the code(it will load MLO) in internal rom of beaglebone. Jul 04 07:21:28 Rocky, not likely Jul 04 07:21:40 not likely at all... Jul 04 07:23:19 ok, when I boot my bad bb, i can't see any serial output, also I can't capture any network packets between my dhcp server and my bad beaglebone Jul 04 07:25:10 any ideas? Jul 04 07:26:23 the baud rate is 115200 Jul 04 07:28:04 any lights? Jul 04 07:33:13 yes Jul 04 07:33:24 4 leds are lighted Jul 04 07:33:32 always Jul 04 07:33:37 solid then. Jul 04 07:33:44 yes Jul 04 07:33:52 never down Jul 04 07:46:41 can you check to see if the crystal is oscillating? Jul 04 07:47:00 otherwise I'd call RMA on this Jul 04 08:05:48 how to check Jul 04 08:05:49 ? Jul 04 08:06:17 you use an oscilloscope and measure the crystal Jul 04 08:07:02 ok Jul 04 08:07:04 thanks Jul 04 08:13:54 if its not going then I'd RMA the board immediately Jul 04 08:14:13 also given what you are saying its entirely possible that its DOA Jul 04 08:18:52 doh. Jul 04 08:18:57 another beagle eats the dust Jul 04 08:19:34 http://www.youtube.com/watch?v=rY0WxgSXdEE Jul 04 08:23:51 what is RMA and DOA? Jul 04 08:24:09 i dont know these terminology Jul 04 08:24:49 http://26-26-54.hardwarebug.org/117 Jul 04 08:25:17 RMA = rreturn merchandise authorization DOA = dead on arrival Jul 04 08:25:48 Rocky: have you really *never* bought any broken electronic part? Jul 04 08:26:12 lucky Jul 04 08:28:35 got myself a new toy yesterday Jul 04 08:28:35 :) Jul 04 08:28:36 ant_work: either very young, or never bought any hardware Jul 04 08:28:46 ant_work: the latter is more likely Jul 04 08:29:35 http://i.imgur.com/AjYULz6.jpg Jul 04 08:29:42 yes Jul 04 08:29:51 I'm a young boy Jul 04 08:29:57 mmm Jul 04 08:30:01 how young are you rocky? Jul 04 08:30:05 I like young boys Jul 04 08:30:07 18 Jul 04 08:30:16 where do you live Rocky? Jul 04 08:30:21 Rocky, what is your opinion about the bieber Jul 04 08:30:42 stop hitting on my guy panto, he's not interested in you Jul 04 08:30:43 china Jul 04 08:31:00 ooh so you are a young asian boy? Jul 04 08:31:02 I like kobe Jul 04 08:31:04 do you have any hair? Jul 04 08:31:06 yes Jul 04 08:31:06 * panto kicks emocakes Jul 04 08:31:22 * emocakes combs what is left of his hair to the side Jul 04 08:31:32 Be polite，thanks Jul 04 08:32:10 http://i.qkme.me/35k7vz.jpg Jul 04 08:32:44 how to make RMA? Jul 04 08:33:04 http://beagleboard.org/Support/RMA Jul 04 08:35:57 mranostay_gone: http://dilbert.com/fast/2013-07-04/ Jul 04 08:36:06 mranostay_gone: you only have to wait anouther 5 years :) Jul 04 08:38:39 thanks. Jul 04 08:49:41 Rocky, sorry to tell you that...but based upon what you are saying that is what I would do. Jul 04 08:54:59 这里的人很奇怪 Jul 04 08:54:59 不要担心 Jul 04 08:54:59 哈哈 Jul 04 08:56:31 they are talking in shrubs again! Jul 04 08:56:50 rocky: where in china are you ? Jul 04 08:56:54 mrpackethead: already started sourcing the components (resistors and 0603 caps and LEDs for now, just to get some practice before taking on the fun stuff) Jul 04 08:57:27 next time we do a 'co-op' cape, maybe we should do the parts sourcing Jul 04 08:57:28 as well Jul 04 08:57:52 kfoltman: i'd put on the FPGA first Jul 04 08:57:58 before i did anything else Jul 04 08:58:37 无聊 Jul 04 08:58:38 他去到月球 Jul 04 08:58:47 suspect that is not the right characters Jul 04 08:59:05 mrpackethead: I'll try to keep the safety margin around the FPGA and the 74AUP1T157s I think - why would you start with FPGA? Jul 04 08:59:21 because its the thing you'll most likely have trouble with Jul 04 08:59:30 hve you done any SMD before? Jul 04 08:59:58 mrpackethead: no, apart from trying to desolder components from a commercial board using crappy soldering iron - that's why I'm starting with resistors Jul 04 09:00:53 mrpackethead: and I managed to tear apart a few fuses in the process Jul 04 09:01:12 + components sticking to the iron, etc. Jul 04 09:01:16 kfoltman: this is not an easy board to start with Jul 04 09:01:23 its completely doable Jul 04 09:01:29 but its not an easy one Jul 04 09:01:45 mrpackethead: I know, I've tried to find something easier to practice on first; it doesn't look as scary as I initially thought anyway Jul 04 09:02:02 just use plenty of flux Jul 04 09:02:19 the gold pads won't stick particually well Jul 04 09:06:35 hm, what cape are you talking about? Jul 04 09:07:21 unknown Jul 04 09:07:31 mrpackethead, is this BCC? Jul 04 09:07:42 yes. Jul 04 09:07:42 ynezz: me? mrpackethead's Blank Canvas Cape Jul 04 09:07:52 kfoltman: its not my BCC.. Jul 04 09:08:04 I just had the PCB's made Jul 04 09:08:14 kfoltman, take solder and drag it across the pins Jul 04 09:08:19 just tack the corner pins Jul 04 09:08:26 emeb is the guru, ka6sox is also a guru on it. Jul 04 09:08:41 i just got mine going this weekend. Jul 04 09:09:14 i have a tricky problem to sovle Jul 04 09:09:15 good old drag technique Jul 04 09:09:25 kfoltman, please only tack parts on (chips) then take pictures, then solder the rest after either emeb or I verify orientation. Jul 04 09:09:33 ka6sox: yes, I've been looking at youtube videos, it's just that watching someone else do it and doing it myself is a totally different story :) Jul 04 09:09:40 show himthe drag technique solder pr0n on youtube Jul 04 09:09:42 ka6sox: great idea actually! Jul 04 09:09:59 np Jul 04 09:10:50 kfoltman: you can buy some dummy parts Jul 04 09:10:51 http://www.smtnet.com/company/index.cfm?fuseaction=view_company&company_id=45803 Jul 04 09:11:08 I'm battling with the idea of buying a cheap temperature controlled/hot air combo Jul 04 09:11:20 http://www.youtube.com/watch?v=wUyetZ5RtPs Jul 04 09:11:33 kfoltman, that is an excellent idea Jul 04 09:12:00 okay 2:11am here...up in 6hrs so I'll catch you guys then Jul 04 09:12:16 kfoltman, if you take pics post FULL Size ones someplace Jul 04 09:12:23 some of the marks are TINY Jul 04 09:12:37 ka6sox: I'll use my wife's 550D with extension tube, perhaps ;) Jul 04 09:13:09 and the SPI Flash is real easy to get backwards and hard to see the bevel. Jul 04 09:13:32 http://www.youtube.com/watch?v=erb6-i54tbo Jul 04 09:13:33 the 550 is a good idea Jul 04 09:13:44 okay, I need sleep now... Jul 04 09:13:48 laters folks Jul 04 09:13:55 I haven't tried using it as a pseudo-microscope, worried about fucking up the lens Jul 04 09:14:01 ni ni ka6sox-away Jul 04 09:14:06 I mean, using USB remote shooting feature Jul 04 09:14:25 but perhaps with extra macro ring over the lens it's safe-ish Jul 04 09:14:32 kfoltman, you can make it work...I have been quite successful with that technique Jul 04 09:14:33 a good magnifiying glass with leds in it is relaly useful Jul 04 09:14:34 you have one of those microsoft usb microscopes ? Jul 04 09:14:36 heheh Jul 04 09:14:46 mrpackethead: I don't have one yet Jul 04 09:14:50 m_billybob: what about them? Jul 04 09:14:54 bbl Jul 04 09:14:55 I don't, no Jul 04 09:15:08 USB camera things are just useless Jul 04 09:15:10 dont' bother Jul 04 09:15:41 kfoltman we haveone was just curioius. thought it was funny that someone else would use a kids toy as an electronics tool Jul 04 09:15:44 mrpackethead: what's the problem, bad optics? bad resolution? high latency? Jul 04 09:15:52 all of the above Jul 04 09:16:04 m_billybob: it's a kids hobby for me (even though I have a kid myself :P) Jul 04 09:17:22 kfoltman ny buddy ghs been an ee for ~35 years, so never quite a hobby for us Jul 04 09:17:29 has been* Jul 04 09:17:47 http://www.jaycar.co.nz/products_uploaded/productLarge_13442.jpg Jul 04 09:17:50 something like that Jul 04 09:17:54 is really handy Jul 04 09:18:00 becuase its got a base on it Jul 04 09:18:03 you can rest it on the board Jul 04 09:18:07 and the focus is right Jul 04 09:18:10 it has leds in it Jul 04 09:18:30 this cost me about $25 Jul 04 09:19:06 mrpackethead: the problem is that amazon/ebay/maplin is full of stuff, 90+% of which is junk Jul 04 09:19:20 smeagol: want to play riddles with this hobbit? Jul 04 09:19:52 okay i have one for you Jul 04 09:20:40 I like the magnifying ring lamp we have Jul 04 09:20:51 they're not cheap though Jul 04 09:20:52 mrpackethead: for now, I use a magnifier from one of these "helping hands" thingies (= utter crap) or a Chinese knock-off macro ring for a camera Jul 04 09:22:20 I am interfacing a USB 2.0 Logitech camera with my BEagleboard XM. I have opencv intalled and i'm compiling my codes through codeblocks ide. i am trying to stream a video using cvCaptureFromCAM in an infite while but it is only capturing the first frame and unable to capture any frames after that. Jul 04 09:22:36 smeagol: when is your assignment due Jul 04 09:23:41 its a project..due in a few weeks why? Jul 04 09:25:14 what is your course? Jul 04 09:25:59 mrpackethead: I'll try the 550d approach first (because I don't need to spend any money on that), and if that fails, then perhaps start shopping for a decent magnifier, though I'll probably have a lot of confusion due to junk flood Jul 04 09:26:21 kfoltman: you really do need to be able to get some magification on it Jul 04 09:26:25 however you do Jul 04 09:27:10 you wont' be able to see bridges without it Jul 04 09:32:36 smeagol: ? Jul 04 09:32:46 yes? Jul 04 09:33:40 mrpackethead: http://www.ebay.ie/itm/200929562880 - is it a worthy upgrade over http://www.maplin.co.uk/50w-solder-station-35016 ?

Jul 04 09:46:32 desoldering using a middle manager, now thats an idea Jul 04 09:46:35 lol ebay must be hard up for money now days. since when did they start using google ads on their pages Jul 04 09:46:47 mru: ofc Jul 04 09:47:17 kfoltman: the name "kitchen star" doesnt make very trustworthy Jul 04 09:54:43 i got a weird bbb Jul 04 09:54:54 drops ssh sessiosn from my macbook Jul 04 09:55:01 but everything else runs fine Jul 04 09:55:14 yet, same build, on other machiens is just fine Jul 04 09:55:38 what about connections from other machines ? Jul 04 09:55:53 other machiens are fine as well Jul 04 09:56:16 so not really a bbb thing so much as osx Jul 04 09:56:24 yeah, its just this one machien though Jul 04 09:56:27 its weird Jul 04 09:56:48 mrpackethead: ssh over ethernet? Jul 04 09:56:51 wonder if there are any known issues between osx and openssh-server Jul 04 09:57:06 mrpackethead: could be that the magnetics are not ok or the PHY broken Jul 04 09:57:28 yeah, but then other machiens woudl break Jul 04 09:57:33 not necessarily Jul 04 09:57:40 it's analog, not digital Jul 04 09:57:48 icmp / web / everythign else is runnign fine Jul 04 09:57:56 broken devices just shift the error probability Jul 04 09:58:16 mrpackethead: icmp echo? with all small or large packets? Jul 04 09:59:31 I've had broken ethernet stuff work with some devices and not others Jul 04 09:59:51 and its intermitent Jul 04 09:59:54 jsut for fun Jul 04 10:00:03 but every other device connecting to it works Jul 04 10:00:22 KotH: i'm just running a sweep of ping sizes Jul 04 10:00:52 http://www.adafruit.com/products/451 Jul 04 10:00:55 hmmm Jul 04 10:10:38 KotH: 8 to 1500 bytes, all are ok Jul 04 10:10:44 not a single packet dropped Jul 04 10:10:51 its weird Jul 04 10:11:03 my hop off ssh works Jul 04 10:11:08 ie, ssh to another machine Jul 04 10:11:16 and then to then back to the bbb Jul 04 10:11:31 can have direct connections to the other 4 bbb's in the rack as well Jul 04 10:11:38 so, i'm really not sure whats happening Jul 04 10:12:30 koen: what a simple stepper driver? Jul 04 10:12:33 for 3 stepper? Jul 04 10:14:59 KotH: yes, the "kitchen star" thing is a bit of a turn-off Jul 04 10:16:25 KotH: any known-not-bad alternatives you're aware of? Jul 04 10:24:57 mrpackethead i guess dmesgis of no use ? Jul 04 10:25:12 dmesg is* Jul 04 10:28:45 kfoltman: Leiter HOT JET S Jul 04 10:28:49 kfoltman: that's what we use Jul 04 10:29:28 kfoltman: er.. leister, not leiter Jul 04 10:30:21 What does "bone_capemgr.8: slot #4: Failed to resolve tree" means ? Jul 04 10:31:58 KotH: that's something I'd buy if I had a repair business, but probably a bit of overkill for home use? Jul 04 10:32:20 kfoltman: not really Jul 04 10:32:39 kfoltman: if i wouldnt have access to one at work, i would buy one for home use Jul 04 10:33:04 750$ is probably more than lifetime of burned SMD parts in my case ;) Jul 04 10:33:08 kfoltman: ok.. i have also an ersa digital controlled 80W soldering statin at home, so i might not be a good reference Jul 04 10:33:15 kfoltman: huh? Jul 04 10:33:23 kfoltman: we paid something around 300CHF Jul 04 10:33:58 kfoltman: i know the USD is low, but i didnt know you had a 100% inflation in the last months Jul 04 10:34:21 KotH: I didn't, I'm in EU Jul 04 10:34:26 just checking odd prices here and there Jul 04 10:34:35 kfoltman: ask manufacturer directly Jul 04 10:34:40 kfoltman: it's a german company Jul 04 10:35:44 kfoltman: oh.. correction, it's a swiss company Jul 04 10:36:08 kfoltman: so you have to pay the protective duties of the EU Jul 04 10:36:41 kfoltman: a good temp controlled iron is all you need Jul 04 10:36:45 dont' worry about hot-air Jul 04 10:36:59 KotH: if there's something meant to protect EU, then it's not working Jul 04 10:37:05 they cause mroe problems than they are worth unless you really know what you are doing Jul 04 10:41:16 dwery: it's not meant to protect the EU, but to annoy swiss people Jul 04 10:41:19 dwery: nothing else Jul 04 10:41:38 then I think it's working :D Jul 04 10:41:42 dwery: swiss see the EU often as the big bully Jul 04 10:42:11 eballetbo, no resolve information Jul 04 10:42:15 what are you trying to do? Jul 04 10:42:28 I sure hope you're not trying the 3.10 kernel and expect it to work Jul 04 10:42:35 KotH: bullying the swiss doesn't seem smart to me.. and I don't think it ever worked Jul 04 10:44:08 dwery: it is still done Jul 04 10:44:13 dwery: and often too Jul 04 10:44:20 mrpackethead: I was thinking of learning reflow at some point, perhaps - unless it's clearly a bad idea (people have strong and divided opinions about that) Jul 04 10:44:22 panto, I'm trying to create a custom rootfs for my beaglebone built with Yocto and meta-ti, I'm using kernel 3.8.13 Jul 04 10:44:43 kfoltman: hotair != reflow Jul 04 10:44:44 in that case you're missing -@ from the dtc invocations Jul 04 10:45:01 KotH: I'd suggest to use a negative interest rate on EU bank accounts in CH... Jul 04 10:45:11 dwery: like the germans... the use zrich airport quite often (iirc about 30% of the passengers are germans), but deny the right for planes to pass north of the airport Jul 04 10:45:59 kfoltman: if you want to do something easy, and much more useful, buy or build your self a bench top reflow oven Jul 04 10:46:10 that is a much easier technique Jul 04 10:46:21 or look at the 'skillet' method Jul 04 10:46:34 i built my first smd oven for about $150 Jul 04 10:47:50 panto: What you mean ? I'm just introducing to DT. I'm using kernel from https://github.com/beagleboard/kernel/tree/3.8 Jul 04 10:48:18 kfoltman: what mrpackethead just said! Jul 04 10:48:30 you need to pass -@ to the dtc compiler to generate the required information in the DTB Jul 04 10:48:46 kfoltman: a simple oven with temp control that can be controlled using a pc (for temp curve) is probably the easiest for 99% of your use Jul 04 10:49:06 kfoltman: but you need some way to get the paste onto the board for everything that is not bga Jul 04 10:49:20 oh the sparkfun reflow controller is EOL Jul 04 10:49:23 panto: ok, thanks I'll try Jul 04 10:49:37 kfoltman: on the other hand, we use our reflow oven to resolder dfn/qfn after we soldered them by hand first Jul 04 10:50:20 kfoltman: for everything like passives, qfn, tssop, etc that has the pins outside: we use a fine solder tip and do it by hand Jul 04 10:50:46 mrpackethead, KotH: ok, so a better iron is probably the best option for now Jul 04 10:50:50 KotH: beagle controller Jul 04 10:51:02 KotH: reflow smd controller Jul 04 10:51:07 theres an idea for a spare moment Jul 04 10:51:08 lol. Jul 04 10:51:09 mrpackethead: counts as "PC" for this :) Jul 04 10:51:56 kfoltman: yes, Good iron, tip, flux, good tweezers and maginifying glass Jul 04 10:52:09 hi Jul 04 10:52:20 the oven will just help you speed things up Jul 04 10:52:32 mrpackethead: how do you handle solder paste? Jul 04 10:52:33 I use an oven for doing my prototypes Jul 04 10:52:47 mrpackethead: it's probably easier but big things in rented house when we might want to move any day = bad Jul 04 10:52:54 I mean, reflow oven is Jul 04 10:53:12 kfoltman:, my little oven is about 35x30x30cm Jul 04 10:53:15 its not big Jul 04 10:53:16 sorry guys, I need to go for a moment, I'm at work and explain some derp Jul 04 10:53:20 cost me about $90 Jul 04 10:53:25 mrpackethead: ah! that sounds much better Jul 04 10:53:34 av500: ebay has a few tbs ones Jul 04 10:53:36 kfoltman: to do smd stuff, get a >60W soldering station where you can set the temp. does not need to be digital, you wont be setting the temp to anyhting but in ~50C steps anyways Jul 04 10:53:39 just one of those little bench top thing Jul 04 10:53:39 tbs6 Jul 04 10:53:52 av500: should be be compatible with a parallelport Jul 04 10:54:00 KotH: mine is 50W with a knob, but without a scale Jul 04 10:54:03 kfoltman: a hakko FX-888 is good Jul 04 10:54:24 kfoltman: does not necessarily need a scale. you just need to know how hot it approx gets Jul 04 10:54:32 kfoltman: and that you get from how fast your solder melts Jul 04 10:54:35 hi.. I need help on building modules for beagle board xM C2 running in linux 2.6.32 Jul 04 10:54:48 and really the reading on the dial is just indicative Jul 04 10:55:05 i have a iron temp device Jul 04 10:57:46 Hello Jul 04 11:10:30 https://github.com/pantoniou/testpru Jul 04 11:14:08 strange error in u-boot built by myself, Unknown command 'mmc', Unknown command 'run' Jul 04 11:14:57 forget to enable mmc support? Jul 04 11:15:55 when I try to input help in u-boot command line Jul 04 11:16:12 Unknown command 'help' is printed Jul 04 11:16:22 so you forgot to enable that too Jul 04 11:23:37 yeah the bbb is a bit overkil for a reflow oven though Jul 04 11:23:47 can be done with a single msp430 G2553 Jul 04 11:24:10 * m_billybob has done it Jul 04 11:29:48 koen: tbs6? Jul 04 11:30:38 ah got it Jul 04 11:30:42 no, too much Jul 04 11:30:54 will get 3 LM298 bridges Jul 04 11:49:45 m_billybob: it might be overkill, but consider the time you spend on it vs its cost Jul 04 11:50:21 m_billybob: unless you've done a lot of uC stuff in your life, using a bbb is much faster than programming a uC Jul 04 11:51:13 m_billybob: and even assuming a meager sallary of 100CHF/h, half an hour saved and you will be below the price difference Jul 04 11:55:00 hmm... maybe an arduino might be as fast.. dunno, never tried one of those Jul 04 12:09:35 wow, 100CHF/hour :) Jul 04 12:10:22 meager... right ;) Jul 04 12:11:50 well, if you work for 200CHF/hour, then it could be considered meager :) Jul 04 12:12:52 swissland is expensive though; so I suppose that has to be taken into consideration Jul 04 12:15:19 well, if you'd want to hire me, you'd bay ~200CHF/h Jul 04 12:15:33 ofc, i only get a small part of that money ^^' Jul 04 12:15:56 s/bay/pay/ Jul 04 12:16:03 ah; swiss + consultancy based Jul 04 12:16:09 nope Jul 04 12:16:12 I can almost hear the cash register ;) Jul 04 12:16:19 a consulat costs >500CHF/h Jul 04 12:16:24 do they pay the rest to you in chocolate and cheese ? Jul 04 12:16:37 so you're to hire, but not a consultant? Jul 04 12:16:40 nope, .ch is a BYOC economy Jul 04 12:17:32 * dm8tbr has this old alias in his IRC client from his Insultant days: Jul 04 12:17:32 jackmitchell: we are an contractor engineering company. usually we do whole projects, but from time to time we are hired by the hour when customers have special needs Jul 04 12:17:34 Hire me. My rate would be onehundredandfifty an hour. Plus VAT and expenses. Four hours minimum. Dollars for small problems, Euros for big problems. British Pounds for management problems. Jul 04 12:17:49 dm8tbr: you like that, dont you? :) Jul 04 12:17:55 yeeeees Jul 04 12:18:14 KotH: fair play; makes sense! Jul 04 12:19:15 jackmitchell: ripping off customers never pays off :) Jul 04 12:19:30 hi Jul 04 12:19:30 I heartily concur Jul 04 12:19:59 really depends how big you rip them off ... if you dont need to work anymore afterwards that should work Jul 04 12:20:28 grezi herr mycho, how can we abuse you today? Jul 04 12:20:36 :) Jul 04 12:20:44 :) Jul 04 12:20:50 mucho? Jul 04 12:22:10 * dm8tbr agrees with jackmitchell and KotH - honest approach always paid off best, also in terms of long term moniez Jul 04 12:22:52 + sanity and morality; not that I see much evidence of that in here ;) Jul 04 12:22:59 * SpeedEvil hits dm8tbr over the head, and takes his wallet. Jul 04 12:23:20 jackmitchell: we are very sane and absolutely moral trolls! Jul 04 12:23:49 can you help me: i try to activate the SPI1 interface on my bbb but i dont get it work i tried the instruction on http://hipstercircuits.com Jul 04 12:23:52 have fun with my empty worn out wallet :) Jul 04 12:38:25 mycho: "i have a problem" is not a problem description Jul 04 12:38:41 it does indicate a problem though Jul 04 12:38:52 a problem to communicate Jul 04 12:38:59 a problem with explaining problems Jul 04 12:39:01 mycho: what did you do, why do you think it failed and what did you try to remedy the situation? Jul 04 12:39:31 mycho: and could you please send everyone a box of good swiss chocolate, please? thanks Jul 04 12:41:04 KotH: you know you'll be indexed with 'chocolate' by Google, do you?

Jul 04 12:52:43 Guest638666 seems pretty catchy as a nick Jul 04 12:54:41 KotH: when one guy did change from Guest*** -> foo one friend did the same comment Jul 04 12:54:53 I'm still laughing at the answer Jul 04 12:55:01 "yeah, it took me awhile to think it up - i was becoming pretty Jul 04 12:55:01 i dont live in swiss ;) Jul 04 12:55:01 attached to it and sorry i had to change" Jul 04 12:55:29 * KotH throws exception Jul 04 12:55:39 KotH: damn, you stole my line Jul 04 12:55:50 * exception aaaaaa Jul 04 12:57:10 mru: on earl grey and chocolate, my reaction time is reaching planck time! Jul 04 12:58:01 ok well my problem in detail i know that i have to overlay the device-tree to enable spi so i copiled my overlay code and after that i have to load it right? Jul 04 12:58:12 KotH: on beer and alcohol, guess what reaches planck's length ? Jul 04 12:58:57 mranostay! Jul 04 13:01:42 well ias mentioned in the google group i added "capemgr.enable_partno=BB-SPI0DEV" in uEnv.txt in the boot partition but after rebooting the spidevice didnt show up in /dev Jul 04 13:10:52 mycho: I don't see a cape called BB-SPI0DEV in the firmware directory Jul 04 13:11:27 where did it come from? Jul 04 13:12:53 i downloadid it here http://pastebin.com/DdWtdtds and compiled it Jul 04 13:13:18 ok, and where did you put it? Jul 04 13:14:13 the compiled fil i put in /lib/firmware Jul 04 13:15:05 and you called it BB-SPI0DEV.dtbo Jul 04 13:15:44 BB-SPI0DEV-00A0.dtbo Jul 04 13:16:17 hmmm, I'm no devicetree overlay expert but should the partno=BB-SPI0DEV-00A0? panto? Jul 04 13:17:12 mycho: could you pastebin the output of dmesg? Jul 04 13:19:26 well dmesg dosnt mention spi Jul 04 13:26:03 jackmitchell, default revision is 00A0 Jul 04 13:26:41 Just building a small PCB for the BeagleBone Black. Can anyone confirm that on the BBB, for SPI0, SPI0_D0 and SPI0_D1 are interchangable? Jul 04 13:26:57 panto: and you don't need to state the revision in the enable_partno? Jul 04 13:27:30 mycho: if dmesg doesn't mention spi then it doesn't look like it's even attempting to load the dtb Jul 04 13:27:43 can you post it anyway Jul 04 13:27:44 yea it seams like Jul 04 13:27:59 it will show you kernel commandline which will give some more info Jul 04 13:28:08 and prove that you're doing that correctly Jul 04 13:28:52 which part of dmesg Jul 04 13:28:58 all of it Jul 04 13:29:44 jackmitchell, when you don't supply one the default the revision is 00A0 Jul 04 13:30:02 panto: ok; good to know! Jul 04 13:30:06 thanks Jul 04 13:32:40 well i just got it work by loading the overlay manual Jul 04 13:32:57 there shouldn't be any difference Jul 04 13:33:02 now ther is a spidev1.0 device Jul 04 13:33:14 which points to kernel command line issue probably; which I'm trying to get you to post... Jul 04 13:33:59 i think the whole dmesg is to large for a chat Jul 04 13:34:13 it is, so use pastebin as mentioned earlier Jul 04 13:34:35 http://www.pastebin.com Jul 04 13:37:09 i see Jul 04 13:37:27 paste it in there, then post the link after you've pressed submit Jul 04 13:41:19 http://pastebin.com/Qm1382DN Jul 04 13:43:50 ahh i see by line 793 there are the problems Jul 04 13:44:29 mycho: that;s where you manually loaded it I think Jul 04 13:44:41 yea i see Jul 04 13:44:56 if you look at 146 Jul 04 13:45:08 you can see that it doens't detect that it's being asked to load a cape Jul 04 13:45:42 ok Jul 04 13:45:55 happy 4th everybody! Jul 04 13:46:18 what happens on the 4th? Jul 04 13:46:31 freedom! Jul 04 13:46:47 * depending on prism availability Jul 04 13:47:00 s/availability/downtime Jul 04 13:47:10 we switch to programming in forth for a day Jul 04 13:47:12 panto: is this the right way to specify a cape Jul 04 13:47:22 panto: Kernel command line: console=ttyO0,115200n8 quiet drm.debug=7 capemgr.enable_partno=BB-SPI0DEV root=/dev/mmcblk0p2 ro rootfstype=ext4 rootwait Jul 04 13:47:38 yeah, it's fine Jul 04 13:47:53 it will try to load /lib/firmware/BB-SPI0DEV-00A0.dtbo Jul 04 13:47:56 mycho: I don't know why your cape isn't loading then, it all looks good Jul 04 13:48:43 well i guess that the capemgr.enable_partno feature is only supported in newer kernel then mine i just used the board out of the box Jul 04 13:50:01 but im lucky that manual loading works Jul 04 13:50:43 mycho, ugh Jul 04 13:50:52 the maual loading of the overlay of http://hipstercircuits.com/ dint work soo im happy now Jul 04 13:50:53 yes, this is working only on recent kernel Jul 04 13:51:11 How much of RAM does the beaglebone black have? Jul 04 13:51:22 May 20 Jul 04 13:51:29 CyL: http://beagleboard.org/ Jul 04 13:51:58 jackmitchell: Well, I'm there, but this particular information seems to be a bit buried Jul 04 13:52:20 CyL: I appologise, I've just looked and you're right. It isn't obvious Jul 04 13:52:30 CyL: http://circuitco.com/support/index.php?title=BeagleBoneBlack#BeagleBone_Black_Features Jul 04 13:52:57 ok thanks for the great help anyway im totaly new to devicetrees Jul 04 13:53:09 CyL: there is the hardware manual. a huge pdf that contains all sorts of information Jul 04 13:53:13 CyL: you should read that Jul 04 13:53:36 Also it states that it has a dual microncontroller, I did not understand if this is a single chip dual core, or it is dual chip single core Jul 04 13:53:37 I concur that it should also be on the front page though Jul 04 13:54:20 CyL, there's a big ARM8 running at 1GHz Jul 04 13:54:23 that's running linux Jul 04 13:54:28 KotH: Oh, I surely will after I buy one of them, but I'm still just considering Jul 04 13:54:39 there are two PRU running at 200MHz (that's like AVRs ) Jul 04 13:54:40 CyL: microcontroller? an A8? Jul 04 13:54:56 there's also a hidden ARM-m3 core just for PM Jul 04 13:55:04 and of course whatever the GPU has Jul 04 13:55:16 KotH: 2x PRU 32-bit microcontrollers <-- from the front page Jul 04 13:55:29 CyL: ah.. PRU != processor Jul 04 13:55:36 KotH: I'd call it mcu no matter powerfull it is if it has embedded IO hardware Jul 04 13:56:01 KotH: But that's just my personal non professional opinion Jul 04 13:56:02 KotH, it's a processor alright Jul 04 13:56:08 CyL: so, you'd call a 8 core xeon a uC if it is in an embedded system? Jul 04 13:56:19 feels just like early RISC era Jul 04 13:56:54 KotH: Not if it is an embedded syste, if it has embedded IO hardware bult into the chip, like serial ports, flash memory interfaces, ethernet hardware and so on Jul 04 13:57:24 panto: who's responsible for the bbb page? Jul 04 13:57:36 the ether Jul 04 13:57:39 KotH: But again, that's just me, that's the big difference I see in MCU and GP uP's nowadays Jul 04 13:57:54 CyL, what you call GP uP is dying Jul 04 13:57:57 CyL: that's called SoC these days :) Jul 04 13:58:02 panto: Agreed Jul 04 13:58:04 even intel is moving away from that model Jul 04 13:58:30 there's a huge number of transistors that's just idling in the CPUs Jul 04 13:58:40 putting more cores in is not helping much Jul 04 13:58:41 KotH: Well, SoC is a bit more general than MCU's in the sense it has programable hardware in it as well Jul 04 13:58:56 however getting rid of the south/north bridges is a good design Jul 04 13:58:59 intel chips are getting ever more stuff built in Jul 04 13:59:05 mru, +1 Jul 04 13:59:24 KotH: Also routable pins is a notable feature of SoC's, but MCU's re starting to copy it as well Jul 04 13:59:36 I expect to see onchip sata soon Jul 04 13:59:40 if they don't already have it Jul 04 14:00:00 ethernet will likely follow Jul 04 14:00:02 CyL: what counts as "programmable hardware" for you? Jul 04 14:00:16 KotH: What about a few logic gates? Jul 04 14:00:16 mru: some of the TI uP's already have onboard sata Jul 04 14:00:31 I meant intel chips Jul 04 14:00:42 mru: some of the ex luminary chips already have onboard ethernet PHY Jul 04 14:00:49 mru: ah.. ok Jul 04 14:00:52 onchip sata/eth in embedded systems is nothing new Jul 04 14:01:03 Anyway, would you guys indicate any retailer that ships international? Jul 04 14:01:32 panto: who do i pester to suggest a small change on the page to make things a bit more clear? Jul 04 14:01:41 send an email Jul 04 14:02:00 CyL: digikey Jul 04 14:02:02 farnell Jul 04 14:02:04 some others Jul 04 14:02:11 av500: Thanks Jul 04 14:02:31 panto: ack Jul 04 14:18:14 hi ka6sox Jul 04 14:18:37 hoi ka6sox-here Jul 04 14:21:03 mourning panto KotH Jul 04 14:21:17 why am I UP?...its a holiday!

Jul 04 14:35:29 you have 2 hours Jul 04 14:36:28 what sound does a single troll clapping make? Jul 04 14:36:38 only if channelguard lives there Jul 04 14:36:48 (or is that the channel troll?)

Jul 04 14:42:32 mru: it's one of the few tv series, which that country on the other side of the big pond produced, that has a consistent story over more than two episodes Jul 04 14:42:47 but it's a crap story Jul 04 14:42:56 but at lest it _is_ a story Jul 04 14:42:59 least* Jul 04 14:43:07 ok, _some_ of the story elements are interesting Jul 04 14:43:12 but the characters are utterly shit Jul 04 14:44:03 the problem with many tv shows is that they get extended well beyond their natural life span Jul 04 14:44:17 d'oh posedge reset != negedge reset. Jul 04 14:44:44 and then there are some who get cut off at the knees before starting (RIP Firefly) Jul 04 14:45:12 firefly was fun, but it honestly wasn't really that spectacular Jul 04 14:45:26 * KotH acks mru Jul 04 14:45:41 that said, I would've watched a couple more seasons of it Jul 04 14:46:16 even galactica, great as it was, dragged it out in the end Jul 04 14:46:50 and as so many others, it devolved into spiritual mysticism Jul 04 14:47:13 deus ex machina Jul 04 14:47:18 always helps Jul 04 14:47:54 av500: in the end? you mean after the first season Jul 04 14:48:06 hmm, after EOMA-68 and EOMA-26, I wonder if lkcl will come up with EOMA-4, that uses a USB connector only Jul 04 14:48:37 KotH: at first it was mostly a few wackos spouting religious crap Jul 04 14:48:45 EOMA-1 because 1 Wire should rule them all. Jul 04 14:48:46 av500: not at it again is he? Jul 04 14:48:54 always Jul 04 14:49:00 always, so not again Jul 04 14:49:57 av500: what's the point of the EOMA standards? Jul 04 14:50:12 ego stroking Jul 04 14:50:18 make lkcl feel good? Jul 04 14:51:17 KotH: the point of eoma-68 is "PCMCIA connectors are cheap" Jul 04 14:51:29 so, lets build a so called standard around them Jul 04 14:51:33 lol Jul 04 14:51:39 its true Jul 04 14:51:48 I know this mindset Jul 04 14:51:52 PCMCIA connectors have been cheap.. what? 5y? 10y? ago Jul 04 14:51:53 isn't pcmcia already a standard around them?

Jul 04 15:05:27 Yes, I have subscribe these books on safari Jul 04 15:05:36 Rocky: that's imho nod a bad book, but it requires already quite some linux knowledge to understand it... and it's getting a bit long in the tooth Jul 04 15:05:40 i need some time to take a look those. Jul 04 15:06:06 embedded linux primer is a good book Jul 04 15:06:08 I have several years experience on linux Jul 04 15:06:53 Rocky, did you get the BBB going? Jul 04 15:07:00 not bbb Jul 04 15:07:03 just bb Jul 04 15:07:18 * koen loses faith in humanity Jul 04 15:07:24 koen: you had some? Jul 04 15:07:30 Rocky: "The Design of the UNIX Operating System" by bach is also recommended reading for anyone doing low level unix stuff Jul 04 15:07:31 the "ethernet kills hdmi" thread keeps going and going Jul 04 15:07:33 not, I don't have oscilloscope Jul 04 15:07:53 Rocky: it explains quite clearly _why_ the interfaces and systems look like they do Jul 04 15:07:56 * koen gives in and responds directly explaining NTP and display blanking Jul 04 15:08:15 slow down, i need some time to take the name of these books Jul 04 15:08:18 koen: what has ntp to do with display blanking Jul 04 15:08:19 3 books?

Jul 04 15:24:46 or emmisarry Jul 04 15:24:47 yeah, picture that: my employer blocks IRC and git ... how the hell am I supposed to "work" Jul 04 15:24:58 exception: do they block ssh? Jul 04 15:25:03 * m_billybob has been watching too much ds9 lately Jul 04 15:25:07 i'm a cisco employee Jul 04 15:25:11 :( Jul 04 15:25:19 we know Jul 04 15:25:33 jmoyerman: not really (can always trick) but it's against comapny rules to ssh out of the site Jul 04 15:25:59 exception: ooh... my school blocks IRC, so I just ssh to my box at home :D Jul 04 15:26:03 exception: I just pushed through freenode and customer IRC server access on our corporate firewall. "Business need" and "Essential for contractual delivery" helps a LOT Jul 04 15:26:21 have a joke Jul 04 15:26:27 exception: if my employer would do that, i would say exactly that :) Jul 04 15:26:43 say what? KotH Jul 04 15:26:53 howthe hell am I supposed to "work" Jul 04 15:26:57 good thing I quit before my ex-employer got bought by cisco Jul 04 15:26:58 well, IRC I can always use qweb or smth ... git is more of a problem .. they think SVN is king here Jul 04 15:27:09 it's a little sad Jul 04 15:27:16 good thing i'm responsible for our firewall Jul 04 15:27:22 heh Jul 04 15:27:37 git is more powerful that svn, in my personal option Jul 04 15:27:52 Much more powerful Jul 04 15:27:57 exception: where are you? Jul 04 15:28:16 exception: only a problem for me if the git/gerrit/whatever runs on some funky port. same 'enforcement' as above applies. Jul 04 15:28:39 KotH: Sagem Jul 04 15:28:39 I used to work for a company that blocked git... had to pull down and recompile stuff all the time, hooray unlimited tethering on my cell phone. Jul 04 15:29:01 thats why they implemented git smart http mode Jul 04 15:29:22 isnt that why vpn's exist ? ;) Jul 04 15:29:34 exception: oh.. they are into "defense"... Jul 04 15:29:42 exception: not my fault that you sold your soul Jul 04 15:30:24 jmoyerman: wrong approach Jul 04 15:30:35 jmoyerman: i would have sat there, waiting for the admins to open up access Jul 04 15:30:42 +1 Jul 04 15:30:54 jmoyerman: and explaining every manager who would ask me why i wasnt working what the problem is Jul 04 15:31:20 KotH: it was my manager's cell phone the project tethered off of... lol. Jul 04 15:31:30 jmoyerman: stupid manager Jul 04 15:31:37 too bad it was unlimited Jul 04 15:31:47 how about "xchat azure" on apple store Jul 04 15:31:55 jmoyerman: he was probably violating some company rule :) Jul 04 15:31:55 exception: sagem where? Jul 04 15:32:11 KotH: Probably Jul 04 15:32:17 anyways.. time to go home and enjoy my friday evening Jul 04 15:32:29 av500: near Paris, in the 92 Jul 04 15:32:32 Rocky: baidu for "irc client mac" Jul 04 15:32:38 exception: massy?

Jul 04 15:32:57 somehwat close Jul 04 15:33:38 ah Jul 04 15:34:04 it's not Sagem strictly speaking, SagemCom actually Jul 04 15:34:13 since Safran only bought what interested it Jul 04 15:34:13 exception: I meant the other Jul 04 15:34:19 the massy one Jul 04 15:34:28 worked there ? Jul 04 15:34:30 no Jul 04 15:34:32 passed by Jul 04 15:34:34 :) Jul 04 15:34:39 close to my novotel Jul 04 15:34:43 lol Jul 04 15:35:17 france company Jul 04 15:35:22 you're in france right now ?

Jul 04 15:35:53 I work for a french company but not in france :) Jul 04 15:36:00 I think its the only sane way :) Jul 04 15:36:13 you could work for a non-french company Jul 04 15:36:19 yes Jul 04 15:36:20 which company, av500 Jul 04 15:36:21 I'd rather work for a foreign company in france Jul 04 15:36:26 or that Jul 04 15:36:30 maybe next time Jul 04 15:36:35 Rocky: Archos Jul 04 15:36:41 maybe, sometimes later, I will be you colleagues Jul 04 15:36:42 exception: send me a baguette when you go :D Jul 04 15:36:50 jmoyerman: I live there Jul 04 15:37:11 does this company has one brach in china?

Jul 04 15:43:27 exception: the company is Jul 04 15:44:46 so you'll be there next week ? Jul 04 15:45:20 what is the server url of this chatting channel Jul 04 15:45:32 i open the xchat, but i do not how to use Jul 04 15:45:39 Rocky: irc.freenode.net Jul 04 15:46:30 Rocky: /help, /server, /join Jul 04 15:46:59 koen, after ALL that it was a *hardware* problem??? Jul 04 15:49:19 ka6sox: but how did ethernet desolder his HDMI connector? Jul 04 15:49:22 excess heat? Jul 04 15:49:28 due to high bandwidth? Jul 04 15:49:37 all this NSA traffic? Jul 04 15:49:38 neutrinos Jul 04 15:49:38 heh Jul 04 15:49:50 most likely it came from the factory like that Jul 04 15:50:00 m_billybob, +1 Jul 04 15:50:43 think its funny that people can put 5million postson the groups though and suddenly after irritating many people, figure out on their own what actually hapened Jul 04 15:50:55 and yeah, its happened to me before too :/ Jul 04 15:51:08 av500, without the ethernet attached the HDMI made contact...when the ethernet was plugged in it torqued the board and made the HDMI fail. Jul 04 15:51:51 that is what they want you to believe Jul 04 15:52:27 which board? Jul 04 15:52:39 maybe he was following the USB host mod/guide and decided to try and make his ethernet port a "HDMI host adapter" ? Jul 04 15:53:06 ^^ as logn as we're tossing out far fetched ideas ;) Jul 04 15:53:33 lol, PRU internal timers look like they're wonky Jul 04 15:53:55 timing off panto ? Jul 04 15:54:13 no, something's off in the hardware Jul 04 15:54:38 high update rates miss hitting the timer compares Jul 04 15:54:40 wonder if that has anythign to do with why TI removed all PRU info from their docs Jul 04 15:55:08 no, it has to do with the amount of support required to get it to work Jul 04 15:55:37 anyway, rock solid waveforms with C in the few us range Jul 04 15:55:55 what are you doing with it anyways ? Jul 04 15:56:02 making it go Jul 04 15:56:06 .... Jul 04 15:56:16 mmh maybe I could replace my complicated home automation thingy with LX800+AVR32 with PRU ... Jul 04 15:56:37 well, I want to do multiple pwms Jul 04 15:56:42 koen, are you here? Jul 04 15:57:04 define multiple Jul 04 15:57:45 how many pins you've got? Jul 04 15:58:03 panto personal project of mine, well pet project was to make a mppt charge controller. need high switch / ADC read rates figured someday when i get aroudn to it I'd try using the PRU for such a task Jul 04 15:58:47 the problem with the PRU is the learning curve and the standard s/w support is just... immense Jul 04 15:58:58 uhh ohh... up to 77% device usage on the BCC Cape Jul 04 15:59:05 learnign curve of whcih aspect ? Jul 04 15:59:22 very constrained env, (8K code/8K data) Jul 04 15:59:26 assembly programming Jul 04 15:59:29 no problem Jul 04 15:59:30 cludgy Linux interface Jul 04 15:59:36 none of those are problems for me Jul 04 15:59:43 oh they are Jul 04 15:59:44 well the last one there may be Jul 04 15:59:48 you just don't know it yet Jul 04 16:00:05 panto: what, we don't like curves here? Jul 04 16:00:16 only on serif typefaces Jul 04 16:01:00 panto i think understanding how and what i can do with the hardware would be more of a hurdle Jul 04 16:01:12 but no hands on yet so . . . Jul 04 16:01:17 you'd be forgiven for thinking that Jul 04 16:01:19 yes, that's the start Jul 04 16:01:20 but this is TI Jul 04 16:01:28 but the s/w is the _big_ problem Jul 04 16:01:54 you don't know how hard it is to do trivial stuff Jul 04 16:01:59 meaning interfacing Linux ? Jul 04 16:02:04 yes Jul 04 16:02:26 I guess that would have to do with the share memory "thing" Jul 04 16:02:31 i read somethign about that before Jul 04 16:02:37 my point is, that I'll prep something so that you guys can start working on your problem without dealing with that crap Jul 04 16:02:54 a youtube PRU tutorial ? Jul 04 16:02:55 very cool of you :) Jul 04 16:03:00 lol Jul 04 16:03:03 youtube? Jul 04 16:03:04 lol Jul 04 16:03:05 that would be cool too Jul 04 16:03:20 panto send all your docs to Derek and let him do it for you ;) Jul 04 16:03:34 ( youtube video that is ) Jul 04 16:03:42 i have connected the server, what is the next step to connect this chatting room? Jul 04 16:03:55 Rocky: /join #channel Jul 04 16:03:57 Rocky /join #beagle Jul 04 16:04:14 http://pastebin.com/s3Y5b6Gw Jul 04 16:04:34 ah right, I always forget that pastebin is blocked here too -_- Jul 04 16:04:43 that's a standard tty connected to the PRU, controlling the hi and lo of a pwm generator (in us) Jul 04 16:05:08 beagle? Jul 04 16:05:16 #beagle Jul 04 16:05:19 only me in this channel Jul 04 16:05:27 panto: care to paste on codepad or smth ? Jul 04 16:05:46 https://github.com/pantoniou/testpru Jul 04 16:05:57 Rocky: then you're on the wrong server (/server irc.freenode.net) Jul 04 16:06:06 panto: ty Jul 04 16:06:23 i cannot connect to this server, sad! :( Jul 04 16:06:42 and that's C code using the TI beta compiler Jul 04 16:06:51 I think jkrinder will release it shortly Jul 04 16:07:00 if you do stuff in assembly it's going to be even faster Jul 04 16:07:05 panto so no more asm ? Jul 04 16:07:23 *confused* Jul 04 16:07:26 but, for many cases of applications stuff in the usec range are enough Jul 04 16:07:28 Real programmers use assembly :P Jul 04 16:07:35 m_billybob, only if you need it Jul 04 16:07:38 8k ram and you think you can afford compiled code? Jul 04 16:07:48 oh you can Jul 04 16:07:52 8k ram is a lot.... Jul 04 16:07:55 jmoyerman: you can also flip bits directly in the chip using a probe Jul 04 16:07:56 real programmer dotn give a sh*t what other people think about their programming language of choice. Jul 04 16:08:04 you just have to be careful :) Jul 04 16:08:06 m_billybob: exactly haha Jul 04 16:08:21 :P Jul 04 16:08:40 jmoyerman as i say this . . . im playing with php :/ Jul 04 16:08:52 so yeah . . . shoot me later ill probaby need it Jul 04 16:08:55 I'm trying to setup JTAG on the BeagleBone (White) from Linux with openocd. It's asking for "ft2232_device_desc" or "ft2232_serial" in the config file. What should I put?

Jul 04 16:09:26 heh Jul 04 16:09:45 exception, probaby has to do with optimization / code size than age Jul 04 16:09:46 did younger people not learn to write infinite loops?

Jul 04 16:11:05 with the code generation Jul 04 16:11:31 exception dissasemble your code sometimes, and see for yourself Jul 04 16:11:34 you rely on the compiler detecting that there's no condition to check Jul 04 16:11:44 ain't nobody got time for that Jul 04 16:11:51 exception, your loss Jul 04 16:11:52 actually... I prefer while(2), but it confuses most people :D Jul 04 16:11:54 no body except those who care Jul 04 16:12:01 alright i'll give it a try, seems fun Jul 04 16:12:08 jmoyerman: :D Jul 04 16:12:17 jmoyerman: while (!!1) Jul 04 16:12:26 not not 1 eh Jul 04 16:12:29 that's sure to cause some confusion Jul 04 16:12:45 while( 1==1) ?

Jul 04 16:20:25 0x81680085 Jul 04 16:20:46 no idea i try to avoid using microsoft's compilers. Jul 04 16:21:07 Me too... Last job had a Windows Based app though Jul 04 16:21:14 I love VS though Jul 04 16:21:18 eeeew Jul 04 16:21:37 VS is nice, when they finally got the UI looking nice (2010 i think) Jul 04 16:21:43 no it's not Jul 04 16:21:53 it's a stinkin' ide Jul 04 16:21:57 although. I prefer emacs and a terminal lol. Jul 04 16:21:58 matter of opinion mru Jul 04 16:22:05 and also a personal preference Jul 04 16:22:11 people who use IDEs haven't understood unix Jul 04 16:22:13 hence "I prefer" Jul 04 16:22:36 It's whatever is best, most comfortable, and easiest for a particular dev/team of devs Jul 04 16:22:39 and it depends on the project too. Jul 04 16:22:42 mru, people who complain about what others prefer is what then ? Jul 04 16:22:51 pendantic ? Jul 04 16:22:59 ( nope ) Jul 04 16:23:02 No... that's a wonderful flag for GCC Jul 04 16:23:17 gcc can be used in VS though . . . Jul 04 16:23:23 just not directly Jul 04 16:23:36 m_billybob: what do you think of people who prefer bud light? Jul 04 16:23:39 well without using / creating plugins Jul 04 16:23:52 I think it's safe to say they haven't understood beer Jul 04 16:23:59 mru i think peopel have the right to like what they want so logn as its not forced on me Jul 04 16:24:21 i bet you're into vi ? Jul 04 16:24:23 vim ? Jul 04 16:24:27 emacs ? Jul 04 16:24:28 I mostly use emacs Jul 04 16:24:40 see i couldnt stomache any of those well maybe vim Jul 04 16:25:08 i dont tolerate vi though period cant stand it Jul 04 16:25:29 original vi is a bit limited for any serious editing Jul 04 16:25:37 but it's a huge step up from ed Jul 04 16:26:03 which I only use when there's really no other choice Jul 04 16:26:07 It depends what I'm working on.... I prefer emacs + cedet + ecb for anything C related, Eclipse for anything Java... Jul 04 16:26:09 (yes, that has happened) Jul 04 16:26:12 well just saying everyone likes different things Jul 04 16:26:27 and some people like the wrong things Jul 04 16:26:38 again, thats subjective Jul 04 16:26:48 emacs or vim is subjective Jul 04 16:27:02 m_billybob: methinks he's trolling just a tad bit Jul 04 16:27:10 i know he is Jul 04 16:27:11 lol Jul 04 16:27:13 refusing to understand unix is lazy Jul 04 16:27:20 he'll carry one as long as i do ;) Jul 04 16:27:27 carry on* Jul 04 16:27:32 mru: refusing to use linux/unix properly is lazy Jul 04 16:27:52 yes, and slapping a stupid IDE over it is not proper Jul 04 16:27:53 mru what does an OS have to do with a prefered text editor ? Jul 04 16:28:31 unix is already a fully-featured development environment Jul 04 16:28:36 and in the context of gcc VS is just an overglorified text editor with perhaps a few useful featuers Jul 04 16:28:40 there is no need to reinvent it all poorly inside a closed box Jul 04 16:29:04 mru: that is if you're on a system that has a compiler... Jul 04 16:29:17 how would you do development without a compiler? Jul 04 16:29:36 My beagles don't have compilers on them... Jul 04 16:29:42 nor do mine Jul 04 16:29:42 as far as while(1) and for(;;) go, I got same assembly for both Jul 04 16:29:44 ....

Jul 04 16:31:01 that's just shorthand for --be-stupid Jul 04 16:31:02 dunno, just to make sure it's the default :) Jul 04 16:31:18 hey, I like to write rebase --interactive too Jul 04 16:31:21 there is very rarely any reason to use less than -O2 Jul 04 16:31:34 afk Jul 04 16:31:42 mru: yes there is, to tell your boss you need a more powerful system :D Jul 04 16:31:42 I can do O2 but I bet same result for this Jul 04 16:32:14 that said, even -O0 will probably give the same code Jul 04 16:34:26 Ugh... Verilog warnings are annoying Jul 04 16:36:15 haha Jul 04 16:37:49 exception, anyhow i was yanking your chain, but i was also serious. No idea why panto uses for(;;) though Jul 04 16:38:08 it's the proper syntax Jul 04 16:38:09 arf Jul 04 16:38:32 one of the scope probes does not signal to the scope its 1:10 Jul 04 16:38:37 lots of things are the proper syntax Jul 04 16:38:42 no wonder I measure bs Jul 04 16:38:43 m_billybob: so it *might* have an influence on very old compilers ? Jul 04 16:39:27 exception it could be compiler specific. mspgcc for instance using do{} in place of while or for() can make a code size / performance difference Jul 04 16:39:30 exception: yes, the same anecdotal compilers that prefer ++i over i++ Jul 04 16:39:40 joo Jul 04 16:40:17 AndChat|513876: say something of substance or bugger off Jul 04 16:43:17 mru, not anecdotal Jul 04 16:43:29 panto: can you name one? Jul 04 16:43:36 on the ppc for instance you get pre decrement and post increment Jul 04 16:43:37 I have still not met anyone who could Jul 04 16:43:48 yes, I know many CPUs have these addressing modes Jul 04 16:44:01 so it made a difference how you went through your arrays Jul 04 16:44:04 if(( ++i % 32) ==o) . . . Jul 04 16:44:08 but decent compilers transfor the code so it doesn't matter Jul 04 16:44:10 o == 0 Jul 04 16:44:15 I'll be darned, k&r states for(;;) Jul 04 16:44:16 running forwards you used *++p Jul 04 16:44:18 +m Jul 04 16:44:26 mru, it was gcc Jul 04 16:44:40 the compiler is not always smart enough Jul 04 16:45:16 gcc, for example, will change for() { *p++; } to p--; for () { *++p; } Jul 04 16:45:23 if that's beneficial on the target Jul 04 16:45:28 it shaved one insn from the inside loop of a codec Jul 04 16:45:35 mru, not the version I was using 10 years ago Jul 04 16:46:00 and you know that the compiler like to play it safe Jul 04 16:46:18 gcc back then sucked in many worse ways too Jul 04 16:46:27 so anything might lead to the optimization being turned off Jul 04 16:46:58 mru, my point is that you can always rework the source slightly to get on the compiler's good side Jul 04 16:47:10 if you care about performance Jul 04 16:47:11 there are very few architectures where that transformation isn't always safe Jul 04 16:47:24 before start doing stuff in assembly Jul 04 16:47:28 oh, sure Jul 04 16:47:29 *you Jul 04 16:47:53 so, yeah, I know that writing that function in assembly might make it 30% faster Jul 04 16:47:54 I even gave a presentation on that topic at the last elc Jul 04 16:48:01 I know :P Jul 04 16:48:36 but the tricks needed to keep the compiler happy today are very different from what they used to be Jul 04 16:48:46 sure Jul 04 16:50:11 I've noticed some wierd differences in mspgcc which is based on 4.6.3 gcc I beleive Jul 04 16:50:59 simple things such as compiling a project with G++ versus gcc can produce slightly smaller code, even when using inline with gcc Jul 04 16:51:13 the default optimisations might differ Jul 04 16:51:14 err, on the ppc it's actually pre increment, and post decrement on loads Jul 04 16:51:15 at that scale anythign smaller is usually better Jul 04 16:51:25 afk Jul 04 16:52:34 mru yeah i dont exactly know gcc as well as some of you so could be i missed a possible optimization step with gcc Jul 04 16:53:04 I just got the the poitn where i said fook it and just started compilign with g++ instead Jul 04 16:53:05 the optimisers and backends are the same for all languages Jul 04 16:53:16 but the frontends can enable different passes Jul 04 16:53:35 ill have ot show you an example sometime when i start writting more code for an msp430 Jul 04 16:53:47 I wouldn't be surprised if the c++ frontend by default enables some passes that are mostly a waste with typical c code but often useful for c++ Jul 04 16:54:09 since c++ _really_ sucks without a lot of inlining etc Jul 04 16:54:20 I *know* that between C++ and C the code should compile down to the same thing, but sometimes its more hassle in one language or another Jul 04 16:54:48 there are various flags you can pass to find out exactly what the compiler is doing Jul 04 16:54:54 if you really want to know Jul 04 16:55:18 yeah lots to learn, ill bnever have to worry about not ever having somethign ot keepme busy Jul 04 16:58:08 could be everythign i learned previously with gcc doesnt apply in the case of the toolchain(s) used for / on the bbb Jul 04 16:58:37 --enable-neon Jul 04 16:58:47 no need. Jul 04 16:59:17 neon is audio / video instruction set isnt it ? Jul 04 16:59:26 it's a generic simd instruction set Jul 04 16:59:39 suppose ill have to read up on it sometime Jul 04 16:59:49 that's just one of the options i know about to specify at compile time, there might be others more applicable to your project Jul 04 17:00:15 i *think* but am not sure the current toolchain i use sets all that up by default Jul 04 17:00:22 Linaro gcc Jul 04 17:00:29 for armhf Jul 04 17:00:30 I'm back Jul 04 17:00:45 test Jul 04 17:00:53 test works. Jul 04 17:00:56 it works rocky Jul 04 17:01:05 Rocky you may want to consider leaving with one client Jul 04 17:01:15 this page has info on some compile options http://www.elinux.org/BeagleBoard/GSoC/2010_Projects/FFTW Jul 04 17:01:19 least you get "auto detected" as a "bot" Jul 04 17:01:32 ? Jul 04 17:01:50 Rocky multiple instances of IRC clients on this network can flag you as a bot Jul 04 17:01:56 * _troll_ detects rocky1 Jul 04 17:01:58 in which case you may get a kline or glined Jul 04 17:02:43 gline == global network ban, kline == you get kicked fro mthe server Jul 04 17:02:44 OK Jul 04 17:03:01 thanks Jul 04 17:04:00 Rocky please dont private message me lol i have too many IRC widnows open already . . . Jul 04 17:04:10 windows too Jul 04 17:04:39 mastiff, ok ill check into it but quite possibly ill have to check a difference source of info Jul 04 17:04:46 different* Jul 04 17:05:14 i JUST have a simple test on this IRC client, take it easy, my dear friend Jul 04 17:05:30 i am not 100% sure what info applies accross different toolchain tools but id rather make sure by checkig nthe documentation for my specific compiler Jul 04 17:06:12 e.g. i need to learn exactly what Linaro *is* Jul 04 17:07:50 right now, which my own wordpress theme from scratch ( using php ) isnt lending towards that end goal lol Jul 04 17:08:05 writting my own wordpress theme from scratch* Jul 04 17:09:41 back again Jul 04 17:09:44 m_billybob: can't find one that suits you? Jul 04 17:10:10 m_billybob: are you some kind of masochist? Jul 04 17:10:27 not judging, just asking Jul 04 17:10:28 how can i answer some questions to specific people on this group? Jul 04 17:10:49 Rocky1: typical method is to type their name followed by a : like I just did Jul 04 17:11:01 then their IRC client will either ding or highlight the message stating that their name was used in it Jul 04 17:11:04 and tab completion is your friend Jul 04 17:11:23 Mine's in a shell, so double tap/middle click is my friend. Jul 04 17:11:58 gotta go, lunch time. Jul 04 17:12:06 the client doesn't this feature? it is quite inconvenient for ourself to add the people's name Jul 04 17:12:25 jmoyerman: this is a test Jul 04 17:12:51 jmoyerman: midnight in china Jul 04 17:12:56 need some rest Jul 04 17:12:59 good night Jul 04 17:17:00 m_billybob: heo Jul 04 17:22:05 hello Jul 04 17:23:08 make Jul 04 17:23:11 q Jul 04 17:23:11 q Jul 04 17:23:12 exit Jul 04 17:23:21 help Jul 04 17:24:52 hello Jul 04 17:25:01 Rocky: hi Jul 04 17:25:29 q Jul 04 17:29:57 jmoyerman, not really. mru no, but this is the only way i get exactly what I want. now when i saw from scratch. im using a suitable "blank" theme Jul 04 17:30:14 when i say from scratch* Jul 04 17:30:23 * m_billybob is eating his brunch Jul 04 17:34:50 whew double spicy potato augraten Jul 04 17:35:11 happy 4th, my American neighbours Jul 04 17:35:28 happy 4th Jul 04 17:35:40 Same to ya Jul 04 17:36:32 quite honestly, im less than enthusiastic about this day Jul 04 17:36:46 Whys that? Jul 04 17:36:57 jelous of egypt? Jul 04 17:37:08 how old are you ? dont answer, but lets just say this country is much different than when i was a kid Jul 04 17:37:08 I know I am. Jul 04 17:37:40 Well I'm not as old as you, but I've noticed it also. Jul 04 17:38:14 Get off my lawn! Jul 04 17:38:25 yeah, anyhow lets not get into this again Jul 04 17:38:30 I don't have a lawn, damn water restrictions killed it off. Jul 04 17:38:32 my bad for bringing it up Jul 04 17:38:44 Don't worry, we are on the same page. Jul 04 17:38:52 So I get what you mean. Jul 04 17:39:45 all i can say, is that I pulled a jalapeno out of our freezer that came out of our garden last year, and man my mouth is on fire lol Jul 04 17:40:03 i love it though Jul 04 17:40:19 I have some I picked last year that I'm going to break open later Jul 04 17:40:33 sadly not from the garden though. But at least from a farmers market. Jul 04 17:40:43 we have a huge 4-5 acres garden / orchard area on our property here Jul 04 17:41:05 Nice, how big is the lot? Jul 04 17:41:12 sadly we yet to get any fruit dahme birds seem to get it all before it's ripe Jul 04 17:41:24 40 acres Jul 04 17:41:32 fully fenced off Jul 04 17:41:35 Good sized chunk o' property Jul 04 17:41:47 Were hoping to get into 10-15 in the next couple years Jul 04 17:41:56 Hungry Birds Jul 04 17:42:08 yeah it not bad, but not great either property around here is rathe rdryish, so we have to work it for a few years yet Jul 04 17:42:41 Sounds like most of AZ Jul 04 17:42:51 not exactly desert here, but somethign like high plains Jul 04 17:43:00 sandy high plains Jul 04 17:43:23 Were down right in the middle of hill country Jul 04 17:43:28 south of austin a bit Jul 04 17:43:34 property is getting way to high here though Jul 04 17:43:46 I used to live in mesquite for a while Jul 04 17:44:05 drove a big truck for stevens transport back in the 90's Jul 04 17:44:35 good pay and great learign experience. wouldnt do it again though Jul 04 17:44:37 Haven't been up there Jul 04 17:44:42 I avoid DFW like the plauge Jul 04 17:44:49 lol Jul 04 17:44:59 cant say i blame you Jul 04 17:45:25 hello? Jul 04 17:45:27 seemed every other night on the news some idiot shootign an AK out the back of a station wagon being chased by 500 police . . . Jul 04 17:46:23 Sounds a lot like houston Jul 04 17:47:03 I liked it a lot there though. not because of stuff like that, but because of the closeness of computer related businesses which back then was still a "nerd" thing Jul 04 17:47:13 m_billybob: the Boston bomber chase was something between ridiculous and scary Jul 04 17:47:26 never heard of it Jul 04 17:47:40 but im not exactly form bahston either ;) Jul 04 17:47:49 m_billybob: I mean, the hunt for the marathon bombers a few months ago Jul 04 17:48:03 like, massive overreaction by any european standards Jul 04 17:48:34 kfoltman, oh well lol im not big on current events. I dotn read a paper, dont watch tv ever, and try to avoid news sites ( rigth wing or left wing ) Jul 04 17:48:36 That's what happens in america... we shut down a city and find you. Jul 04 17:49:12 m_billybob: that's a very good strategy in general Jul 04 17:49:19 for an individual at least Jul 04 17:50:06 reading all the crap that hapens now days isnt going ot do me any good Jul 04 17:50:26 matter of fact it'll just piss me off Jul 04 17:51:16 kfoltman, it was a overreation by american standards also Jul 04 17:51:26 they had to test out all that new DHS equipment somehow though Jul 04 17:51:32 stories like kids being ejected from school because they're talkign about, or drawing pictures of guns . . . government school food monitors . . .yeah all that just gets me worked up Jul 04 17:51:34 jmoyerman: two bros with maybe half a brain between them paralyzed the whole city, and they couldn't get them alive (or at least alive enough to answer some questions) Jul 04 17:51:57 kfoltman: oh. I know. Jul 04 17:52:44 at least the good news is that the average 'active' jihadist types (not JIHAD KotH) are apparently getting dumber :) Jul 04 17:53:11 been my understanding that most cant even write or read Jul 04 17:53:18 interesting...gparted doesn't feel like installing... Jul 04 17:53:21 the pawns anyhow Jul 04 17:59:43 Hi, all -- I have a new beaglebone black that I'm trying to reflash. Should I worry that it's been over an hour and the LEDs haven't gone steady yet? Jul 04 18:00:10 any activity ? Jul 04 18:00:23 Yes, lights are still flashing. Jul 04 18:00:33 typicaly i think 40 minutes is about as long as it takes Jul 04 18:00:44 as in disk write activity lights ? Jul 04 18:00:47 I've seen estimates ranging from 30 minutes to an hour. Jul 04 18:01:06 Oh, wait, NM, it just went steady at 1:07 Jul 04 18:01:15 I guess that means I have the record for slowness now. :) Jul 04 18:03:56 guess yo uanswered your own question ;0 Jul 04 18:05:16 Except I don't think it worked. :( After flashing, if I pull out the SD card and plug the BBB black back in, none of the four lights turns on. Jul 04 18:05:38 press an hold down S2 Jul 04 18:05:44 for a second Jul 04 18:05:50 the nrelease Jul 04 18:05:55 then release* Jul 04 18:06:14 you tool the sd card out yes ? Jul 04 18:06:16 Which one is s2? (Looking for a diagram) Jul 04 18:06:18 took* Jul 04 18:06:39 holding the ethernet port down, its the one furthest to the left fro mthe ethernet port Jul 04 18:07:34 Holding that down for a second or two doesn't do anything. Jul 04 18:07:39 and yes, the SD card is out. Jul 04 18:07:44 you took the sd card out ? Jul 04 18:07:52 If I try booting with the SD card still in, then I get lights flashing. Jul 04 18:08:02 ok remove the power form it and leave it unplugged for a few seconds Jul 04 18:08:03 Without the card, nothing but the power light. Jul 04 18:08:32 this happenes to me too once in a while although i use a different distro Jul 04 18:08:43 ( Debian ) Jul 04 18:08:56 im not sur ewhat exactly causes it but there you have it Jul 04 18:09:38 do yo uhave a serial debug cable ? Jul 04 18:09:43 Nope -- left it unplugged for a minute and still the 4 lights don't come on when I plug it in. Jul 04 18:10:04 let it sit Jul 04 18:10:22 all 4 leds should not come on while its booting Jul 04 18:10:24 I have a serial cable I used with a raspberry pi -- this thing, https://www.adafruit.com/products/954 Jul 04 18:10:33 which I think is supposed to work with the BBB too. Jul 04 18:10:42 5v or 3.3v ttl ? Jul 04 18:10:59 It'll be 3.3 since it works with the Pi, I think -- checking to make sure. Jul 04 18:11:15 says 5v Jul 04 18:11:16 Hrmm. Work on getting BBB to work, or go float on the river and drink heavily....decisions decisions. Jul 04 18:11:20 "The power pin provides the 5V @ 500mA direct from the USB port and the RX/TX pins are 3.3V level for interfacing with the most common 3.3V logic level chipsets." Jul 04 18:11:36 I don't normally use the power pin on the pi since it's powered from USB, presume the same would be true of the BBB. Jul 04 18:11:40 ok so yeah as long as you're sure its 3.3v ttl Jul 04 18:11:50 do not hook up the power lol Jul 04 18:12:05 ok so again Jul 04 18:12:10 ethernet port down Jul 04 18:12:19 * m_billybob looks Jul 04 18:13:00 the 6 pin header on the right just next to the right side pinout header. . . Jul 04 18:13:08 pin 1 is furthest down Jul 04 18:13:12 that should be ground Jul 04 18:13:32 4 and 5 are teh tx and rx not sure off hand whcih is whcih but . . . Jul 04 18:14:31 picture i made for this purpose Jul 04 18:14:32 https://lh4.googleusercontent.com/-3oca40vrH-g/Ubd5TjD-0_I/AAAAAAAAALU/-GibZBaTvKk/s1024/beaglebone-black-serial.jpg Jul 04 18:14:37 I suppose it shouldn't hurt it if they're plugged in backward? Jul 04 18:14:49 oh, awesome, thanks Jul 04 18:14:54 ground could be a problem but rx/tx no it just wouldnt work Jul 04 18:15:42 if i were you id double check to make sure ttl is 3.3v Jul 04 18:15:55 better than burning out the serial debug Jul 04 18:16:12 ( ttyo0 ) Jul 04 18:16:58 pb__ ta;lk in here i have tons of chat windows opened already Jul 04 18:16:59 I'm at least sure that it claims to be ... Jul 04 18:17:12 okay, trying it ... Jul 04 18:17:29 plus im writting my own wordpress theme from scratch . .. Jul 04 18:17:38 dont even mention that Jul 04 18:17:38 ( kinda ) Jul 04 18:17:41 Oh, wait, what speed will the serial be? Jul 04 18:17:43 thats my project for this weekend. Jul 04 18:17:50 115200 bps Jul 04 18:17:58 no hardware Jul 04 18:18:03 flow Jul 04 18:18:09 8n1 Jul 04 18:18:17 I took a reasonably customisable theme and added a pile of css Jul 04 18:18:20 good enough for me Jul 04 18:18:39 mru i did the same initially its what my site runs right now Jul 04 18:19:15 turns out though despite my complete lack of php knowlege, that writtign a theme from scratch using a blank theme is much easier Jul 04 18:19:15 Hmm, all I get on serial out is CCCCCC :( Jul 04 18:19:23 eh ? Jul 04 18:19:35 It wants to make sure you are seeing it :P Jul 04 18:19:36 akk: that means it's connected properly Jul 04 18:19:39 did you reset it ? Jul 04 18:19:49 but it's not finding anything it considers bootable Jul 04 18:20:02 Okay, so the flashing didn't work. Jul 04 18:20:09 akk not neccessarily Jul 04 18:20:33 one thing you could do is see what the uEnv.txt file look like Jul 04 18:20:41 Maybe I should try booting with the SD card in and see if it says over serial. Jul 04 18:20:52 maybe Jul 04 18:21:07 Where would I get uEnv.txt? Mounting the image I wrote to the SD card? Jul 04 18:21:15 is that a flasher image ? Jul 04 18:21:36 -> /boot/uboot/uEnv.txt Jul 04 18:21:40 assuming its booted Jul 04 18:21:47 or just /boot Jul 04 18:21:47 If I boot with the card in, I'm getting normal looking Linux boot messages. Jul 04 18:22:12 I downloaded BBB-eMMC-flasher-2013.06.20.img.xz Jul 04 18:22:13 how are you powering the board ? Jul 04 18:22:26 Powering it over a mini USB cable, no other power. Jul 04 18:22:36 what is powering it ? Jul 04 18:22:53 USB 2.0 port on a computer or somethign else ? Jul 04 18:23:40 Oh, hmm, none of the getting-started pages I've found actually mention a login and password for Angstrom. Jul 04 18:23:55 here is the deal the bbb can draw up to 460mA under a full load, which is rather clase to the maximum providable via USB 2.0 . . . Jul 04 18:24:03 The cable is plugged into a USB powered hub plugged in to a linux machine. Jul 04 18:24:09 rather close* Jul 04 18:24:29 I do have another power supply I could use, but I wasn't bothering because all the howto guides said usb was fine. Jul 04 18:24:43 and you're sure the hub is capable of providing 500mA or better per port ? Jul 04 18:25:06 No, I have no idea how to test that. Jul 04 18:25:14 It seems to be running fine with the card plugged in, though ... Jul 04 18:25:30 I can try booting without the card and with a separate power supply if you think that's the likely problem. Jul 04 18:25:42 well it seemed it flashed correctly by what you say what happened but . . .yeah somethign isnt right Jul 04 18:26:06 all thigns being equal i normaly shoot for user error , but most people using the bbb are most likely know wtf they're doing Jul 04 18:26:16 I was thinking it seemed like it didn't flash correctly, since it boots with the card, but not just from the onboard flash. Jul 04 18:26:39 where did you get the flasher image from ? Jul 04 18:26:46 CCo link ? Jul 04 18:26:54 https://s3.amazonaws.com/angstrom/demo/beaglebone/BBB-eMMC-flasher-2013.06.20.img.xz Jul 04 18:27:10 im not familiar with that Jul 04 18:27:12 and I wrote it to the card with dd bs=1M if=BBB-eMMC-flasher-2013.06.20.img of=/dev/sdb Jul 04 18:27:19 is that a link from CCO ? Jul 04 18:27:24 (I had to guess that since I couldn't find any docs that actually said) Jul 04 18:27:46 I went to http://beagleboard.org/latest-images and used the link from there. Jul 04 18:28:12 ok well im kind of out of my element here as I personally dont use angstrom Jul 04 18:28:27 I still have 3.8.8 on emmc here Jul 04 18:28:31 and boot from network Jul 04 18:29:21 Ah, turns out it's root with no password, finally found login info. Jul 04 18:29:32 akk but everythign ive seen Gerlad say on the groups in this respect, he points people to CCo's links Jul 04 18:29:50 If I'm booted from the sd card, can I mount the onboard flash and check uEnv.txt? Jul 04 18:29:56 Gerald too but ok Jul 04 18:30:08 What is CCo? Jul 04 18:30:11 what does blkid say ? Jul 04 18:30:19 circuit co Jul 04 18:30:20 command not found Jul 04 18:30:26 really. Jul 04 18:30:30 mount ? Jul 04 18:30:31 panto: pong Jul 04 18:30:53 /dev/mmcblk1p1 on /media/1, /dev/mmcblk1p2 on /media/2 Jul 04 18:30:56 i suppose fdisk -l would work too Jul 04 18:31:02 maybe one of those is the onboard storage? Jul 04 18:31:17 it'll be a vfat part Jul 04 18:31:30 Looks like /media/2 is a system, /media/1 is uboot stuff. Jul 04 18:31:55 /1 is vfat, /2 is ext4 Jul 04 18:32:11 ok soudns right Jul 04 18:32:20 Maybe uboot got messed up in the flash. Jul 04 18:32:30 look for uEnv.txt Jul 04 18:33:03 /media/1/uEnv.txt contains: optargs=quiet drm.debug=7 Jul 04 18:33:12 thats right Jul 04 18:33:35 what all else is on that parition ? Jul 04 18:33:41 uboot.img and MLO ? Jul 04 18:33:44 App MLO u-boot.img uEnv.txt Jul 04 18:34:12 App is a directory with one file, beaglebone-getting-started.zip Jul 04 18:34:18 so that leaves me wondering if the boot flag is set for that partition Jul 04 18:34:54 I dont recall how to check that offhand without gettign into fdisk Jul 04 18:35:04 maybe fdisk -l would tell ? Jul 04 18:35:15 Device Boot Start End Blocks Id System Jul 04 18:35:15 /dev/mmcblk1p1 * 63 144584 72261 c W95 FAT32 (LBA) Jul 04 18:35:15 /dev/mmcblk1p2 144585 3743144 1799280 83 Linux Jul 04 18:35:20 Looks like the boot flag is set. Jul 04 18:35:35 Assuming that I'm looking at the onboard and not the SD card, anyway. Jul 04 18:35:51 thats the emmc if you've booted from sd Jul 04 18:36:06 Oh, there's also one for /dev/mmcblk0p1 * 63 144584 72261 c W95 FAT32 (LBA) Jul 04 18:36:08 sd would be mmcblk0p1 Jul 04 18:36:16 yeap Jul 04 18:36:38 And ... that /media/1/uEnv.txt was mounted from blk1, not blk0 Jul 04 18:36:46 so I think I need to mount /dev/mmcblk0p1 Jul 04 18:36:57 blk0 is the sd card Jul 04 18:36:57 is there any linux distro commonly used as server where the high security is needed? Jul 04 18:37:15 not concerened wit hthe contents of the sd card ust the emmc Jul 04 18:37:20 Right. Jul 04 18:37:29 Thought maybe 0 would be the built-in. Jul 04 18:37:40 so this is strange not sure why that wouldnt be working Jul 04 18:37:50 no 0 is the devices booted from Jul 04 18:37:58 1 is the other device if any Jul 04 18:38:32 so assuming you booted emmc then the emmc would be blk0 Jul 04 18:38:41 ok Jul 04 18:39:01 so yeah not sure why that isnt working Jul 04 18:39:07 fdisk has nothign else to say ? Jul 04 18:39:51 well let me go ahead and fdisk -l my own here just to make sure i didnt miss something Jul 04 18:39:52 It has lots to say, went on for pages (well, over one page). Jul 04 18:41:11 pastebin the whole output then let me have a lok see Jul 04 18:41:19 look see* Jul 04 18:41:55 mainly just wondering if there arent any other unused paritions Jul 04 18:42:04 if you can figure that outon your own then no need Jul 04 18:42:21 http://pastebin.com/HGjkqgag Jul 04 18:42:56 There are these /dev/mmcblk1boot[01] things, not sure if those are different. Jul 04 18:42:57 Disk /dev/mmcblk1boot0: 1 MB, 1048576 bytes Jul 04 18:43:00 that doesnt seem right Jul 04 18:43:15 Disk /dev/mmcblk1boot0 doesn't contain a valid partition table Jul 04 18:43:27 thats what my ouput has to say Jul 04 18:43:38 Maybe the dd command I used was wrong, needed a different block size or something? Jul 04 18:43:52 I couldn't find anything useful on the web about how to dd the image to the sd card. Jul 04 18:44:03 perhaps yo should go to circuitcos step by step guide Jul 04 18:44:12 I used bs=1M because there was an adafruit tutorial for mac that used that. Jul 04 18:44:27 but look it booted up Jul 04 18:44:37 and you didnt dd the emmc right ? Jul 04 18:44:41 so yeah Jul 04 18:45:08 and actually your poutput looks similar to mine Jul 04 18:45:09 Where's the circuitos one? Jul 04 18:45:33 I didn't dd the emmc, no; dded to the sd card, then booted off the sd card to supposedly flash the emmc (I thought). Jul 04 18:45:44 right you did it rigth if it boots Jul 04 18:45:47 Well, I guess it did flash the emmc. Just not with the right thing. Jul 04 18:45:53 Since it doesn't boot afterward. Jul 04 18:46:14 When I wrote the image to the card, should I have written it to a partition on the card? Jul 04 18:46:31 I wrote it to of=/dev/sdb, not of=/dev/sdb1 -- that was another question I couldn't find the answer to. Jul 04 18:46:43 http://circuitco.com/support/index.php?title=BeagleBoneBlack#Angstrom Jul 04 18:46:58 sdb1 would be a mistake Jul 04 18:47:09 or hmm perhaps not Jul 04 18:47:20 ( off by one error in my head ) Jul 04 18:47:33 no sdb1 would be /boot Jul 04 18:48:43 oh hmm grrrr i hate circuitcos wiki page already Jul 04 18:48:55 ah there we go Jul 04 18:49:08 http://circuitco.com/support/index.php?title=Updating_The_Software Jul 04 18:49:17 yeah, I've been clicking around looking for actual instructions. http://www.crashcourse.ca/wiki/index.php/BBB_software_update_process looks promising. Jul 04 18:50:35 seems he says to use sdx too Jul 04 18:50:35 Funny, it says that eMMC flasher images "are not images to be used to boot from the uSD expecting a desktop or anything close to a good experience" Jul 04 18:50:48 but so far all I've been able to do is boot from the flasher image. Jul 04 18:50:50 lol Jul 04 18:51:04 the bbb wouldnt run as sent to you ? Jul 04 18:51:10 yeah, he uses the same dd command I used. Jul 04 18:51:22 It ran, but I couldn't ssh to it. Jul 04 18:51:37 ah thats a blank file issue with dropbear Jul 04 18:51:40 I could bring up the network and access the web server, but couldn't actually log in. Jul 04 18:51:49 i forget whcih file it is but yeah Jul 04 18:51:54 One page I found said updating the software was supposed to fix that. Jul 04 18:51:57 what distro you run on your desktop ? Jul 04 18:52:17 Debian or Ubuntu, I switch back and forth (debian unstable today). Jul 04 18:52:32 you know you can run debian from the bbb too Jul 04 18:52:35 or ubuntu Jul 04 18:52:38 I'm thinking maybe I should try flashing again, but this time with external power connected. Jul 04 18:52:46 Maybe it had a power glitch during the flashing process. Jul 04 18:53:12 Also, maybe it'll give me some kind of useful info over the serial cable (here's hoping). Jul 04 18:53:15 id follow this guys instructions if cco is linking to him Jul 04 18:53:27 The dd command is the same as I used. Jul 04 18:53:42 of=sdX and bs=1M Jul 04 18:54:23 ha, it panics if I run poweroff Jul 04 18:54:33 What's the right way to shut down? Jul 04 18:55:00 shutdown now -r Jul 04 18:55:10 or shutdown -r now Jul 04 18:55:14 -h whatever Jul 04 18:55:37 angstrom may even have a reboot script not sure Jul 04 18:56:32 Is there a difference between booting off the SD card with the button held in (the boot button, the one near the SD card) and without the button? Jul 04 18:56:56 When I flashed, I held in the button, so I just did that again, but the serial cable gave me boot messages and a login prompt. Jul 04 18:57:03 I don't know if it's trying to flash again, or not. Jul 04 18:57:08 Should I log in and check ps? Jul 04 18:57:41 are you supposed to hold the boot button when installig nthis ? Jul 04 18:58:05 what did the instructions say where you got the image ? Jul 04 18:58:14 that doesnt soundsright to me Jul 04 19:00:43 this guys instructions say yes, hold down the boot button Jul 04 19:00:57 The instructions I saw everywhere said to hold the button down when booting from the flasher card. Jul 04 19:01:06 guess no one bothered to craft an automated uEnv.txt file Jul 04 19:01:20 But at least after flashing, I can boot from it without holding any button down. Jul 04 19:01:53 When I boot with the button down, I get two lines just after the login prompt: libphy: PHY 4a101000.mdio:01 not found Jul 04 19:02:03 and net eth0: phy 4a101000.mdio:01 not found on slave 1 Jul 04 19:02:05 see, i've booted from SD in the past, but the instructions i followed by Robert Nelson have an uEnv.txt file that does not require any button pusing ot take place Jul 04 19:02:14 I don't think I got those when I booted without holding the button. Jul 04 19:02:52 Yes, it's still there in scrollback, no such messages when no button. (Might be a coincidence, though.) Jul 04 19:03:11 sounds like you should start from square one Jul 04 19:03:31 Rewrite the SD card before trying to boot/flash from it? Jul 04 19:03:31 what purpose do you plan on using the bbb for ? Jul 04 19:03:35 yes. Jul 04 19:03:43 I want to do hardware control, robotics. Jul 04 19:04:00 consider this. Jul 04 19:04:09 you're already using ubuntu or debian Jul 04 19:04:34 my personal reccomendation would be to use ubuntu or debian on the bb too Jul 04 19:05:02 but you can boot off of sd for that Jul 04 19:05:15 I may end up doing that. Especially if I can't get Angstrom to work. Jul 04 19:05:41 One friend had been telling me how Angstrom was so much better for hardware control, so I was hoping to try it and see. Jul 04 19:05:42 my reasoning here is simple, I like ot keep my support OS the same as the OS on the BBB architecture aside Jul 04 19:05:52 thats a falshood Jul 04 19:06:32 ok fair enough Jul 04 19:06:43 I was thinking Angstrom might also be lighter weight than the desktop-oriented distros Jul 04 19:06:43 I kept angstrom on my emmc too Jul 04 19:06:55 but looking at ps, maybe not -- it's running things like wpa_supplicant and avahi Jul 04 19:07:18 if you're used to how debian works . .yeah we'll see Jul 04 19:07:24 i think you're going ot get tired of it Jul 04 19:07:26 <_av500_> both blink the cursor at about the same speed Jul 04 19:07:31 you can experience that for yourself though Jul 04 19:07:46 I'm not seeing any processes that look like "I'm busy re-flashing the emmc", though Jul 04 19:08:07 CPU usage ? Jul 04 19:08:22 if its writting to emmc it should be fairly high Jul 04 19:08:36 <_av500_> on angstrom is is emmc.sh Jul 04 19:08:41 <_av500_> that does the flashing Jul 04 19:08:44 I haven't figured out how to get angstrom's ps to tell me that. aux doesn't work, -ef doesn't work. Jul 04 19:08:53 top ? Jul 04 19:09:02 All I've managed so far is ps with no args, which gives me VSZ and STAT but no CPU. Jul 04 19:09:08 led flashing is done on a single toggle basis Jul 04 19:09:13 so you will not find a busy process Jul 04 19:09:25 sounds like it is busybox ps? Jul 04 19:09:29 It does have top; the only thing with significant CPU is /lib/systemd/systemd-journald Jul 04 19:09:44 whats total CPU usage ? Jul 04 19:09:48 for flashing it is not CPU pegged Jul 04 19:09:56 it is IO pegged so sorting by CPU is not productive Jul 04 19:10:04 look for processes in the IOWAIT state Jul 04 19:10:07 Oh, wait, top shows a process, though: cp -r /media/2/usr/share/beaglebone-getting-started/ Jul 04 19:10:14 Hmm, that seems like a silly thing for it to be doing. Jul 04 19:11:00 Ah, ps -w works, it's actually cp -r /media/2/usr/share/beaglebone-getting-started/App /media/2/usr/share/beaglebone-getting-started/Doc Jul 04 19:11:11 heh maybe its copying the rootfs over ? *shrug* Jul 04 19:11:23 What a weird thing for it to be doing. Both on /media/2 Jul 04 19:12:15 I guess I'd better shut down, rewrite the SD and try again, and see what it does then. Jul 04 19:12:51 shutdown -h now also leads to a kernel panic, btw Jul 04 19:13:02 ds2 whats the latest workign image for angstrom ? Jul 04 19:13:09 crazy. Jul 04 19:15:05 seems koen has many Jul 04 19:16:01 i guess this is it ? Jul 04 19:16:04 http://dominion.thruhere.net/koen/angstrom/beaglebone/BBB-eMMC-flasher-2013.03.13.img.xz Jul 04 19:16:29 working is relative Jul 04 19:16:31 ;) Jul 04 19:16:31 03.13? The one I downloaded is 06.20 Jul 04 19:17:02 yeah im having hard time making heads of tails of koens download page here Jul 04 19:17:29 here we go Jul 04 19:17:30 http://dominion.thruhere.net/koen/angstrom/beaglebone/BBB-eMMC-flasher-2013.06.20.img.xz Jul 04 19:17:32 however Jul 04 19:17:41 I think that may be a console only image Jul 04 19:17:50 do you require a desktop ? Jul 04 19:18:03 No, don't need a desktop. Jul 04 19:18:31 <_av500_> a least a bedside table? Jul 04 19:18:36 lol Jul 04 19:19:28 im not sure what is in that image exactly it is pretty small though Jul 04 19:19:36 367M Jul 04 19:20:39 So that's likely better than the BBB-eMMC-flasher-2013.06.20.img.xz (same filename, 369M) I got from the link on http://beagleboard.org/latest-images ? Jul 04 19:21:03 I know nothing about that link you gave earlier Jul 04 19:21:12 do not recognize it at all Jul 04 19:22:01 o7 Jul 04 19:22:06 <_av500_> :) Jul 04 19:22:18 It's the image linked from http://beagleboard.org/latest-images Jul 04 19:22:19 akk it could be exactly the same though Jul 04 19:22:22 Is that not the right place to go? Jul 04 19:22:39 I'm downloading the dominion one, can compare them. Jul 04 19:22:39 akk koen is the source, but yeah seems fine i suppose Jul 04 19:23:02 noting nefarious should be going on from beagleboard.org Jul 04 19:23:22 It just looks like they're using amazon's servers to distribute bandwidth Jul 04 19:23:27 which they even say, somewhere on the site. Jul 04 19:23:42 I wish they gave mdsums or something. Jul 04 19:23:47 <_av500_> yes Jul 04 19:23:50 <_av500_> s3 Jul 04 19:23:59 Usually I don't even bother to check such things, but when things fail horribly, like here ... Jul 04 19:24:43 akk wel you may have missed a step somewhere inbetween Jul 04 19:24:53 it happens especially to me. Jul 04 19:24:54 So now, the question is, wait 15 minutes for the koen image to finish downloading, or start another flash of the image from aws which will take another hour? Jul 04 19:25:13 <_av500_> why should they differ? Jul 04 19:25:21 If I missed a step, I'm gonna miss it again, because the list of steps seems pretty straightforward. Jul 04 19:25:32 <_av500_> there are no steps Jul 04 19:25:37 <_av500_> write image to sd card Jul 04 19:25:38 <_av500_> insert Jul 04 19:25:39 <_av500_> boot Jul 04 19:25:41 <_av500_> done Jul 04 19:25:47 write image to sd card ? Jul 04 19:25:50 <_av500_> hold the usr button while booting Jul 04 19:25:52 what about extraction ? Jul 04 19:25:57 (figuring out the steps wasn't all that straightforward, admittedly) Jul 04 19:26:27 <_av500_> m_billybob: well, when I tell you to read a letter, I expect you to open it Jul 04 19:26:35 av500: Boot with button held down; watch lights for an hour until they go steady; power off are the steps I was following. Jul 04 19:26:42 <_av500_> yes Jul 04 19:26:55 av500 a computer is only as smart as you tell it to be Jul 04 19:27:07 <_av500_> I dont not take akk for a bot Jul 04 19:27:08 Then, unplug; plug back in; watch no lights come on. Jul 04 19:27:14 lol Jul 04 19:27:56 av500 why wouldnt it boot then ? file structure all seemed to be correct. MLO u-boot.img and uEnv.txt were all there Jul 04 19:27:57 * ds2 gasps in amazement Jul 04 19:27:59 Okay, trying again with the re-written aws image. Jul 04 19:28:10 <_av500_> no idea Jul 04 19:28:13 <_av500_> things can go wrong Jul 04 19:28:34 And this time, powered from an external power supply. Jul 04 19:28:55 Anyone know if it's safe to log in (over the serial cable) and check ps while the flash is supposedly happening? Jul 04 19:29:06 yes Jul 04 19:29:07 I got normal bootup messages this time, no errors. Jul 04 19:29:35 already startign to sound better. Jul 04 19:30:10 It has a process {mkcard.sh} /bin/sh ./mkcard.sh /dev/mmcblk1 and another, sfdisk -D -H 255 -S 63 -C 233 /dev/mmcblk1 Jul 04 19:30:13 those look promising Jul 04 19:30:27 akk also for what its worth. from what i understand powering via USB the processor scales speed where as powering via barrel jack i understand you're locked at 1Ghz Jul 04 19:30:55 base speed depending on distro i suppose is 300Mhz Jul 04 19:30:59 no load Jul 04 19:31:05 scales to 1Ghz full load Jul 04 19:31:33 _av500_ - Please help me out on what my real name tell?

Jul 04 19:38:39 :-) Jul 04 19:38:56 no - actually hoping to get to a position of being able to help more upstream Jul 04 19:39:06 although still plenty of work to do Jul 04 19:39:23 but need to start prioritizing helping out upstream as well Jul 04 19:39:28 more than I have done the last years Jul 04 19:39:40 need= would like to Jul 04 19:45:08 It's doing that cp -r /media/2/usr/share/beaglebone-getting-started/ thing again. I'm starting to wish I could get an image that skipped that part. Jul 04 19:46:22 akk maybe later you'll build your own Jul 04 19:46:41 Ah, the script is at /usr/bin/emmc.sh Jul 04 19:46:43 some guy on the groups was saying this morning he builds a 12MB image Jul 04 19:47:02 console-minimal Jul 04 19:48:01 The script has output talking about what it's doing, but I haven't figured out where the output is going.

Jul 04 20:01:33 once i realized it was from beagleboard.org i had little doubt Jul 04 20:02:53 It's doing a bunch of gnome/gconf stuff now, sigh. Jul 04 20:03:41 So that thought about it being a text-only image ... maybe not so much. Jul 04 20:04:05 he definately has enough images there to have one somewhere Jul 04 20:04:11 I wish it sent the output of this script somewhere useful. Jul 04 20:04:19 but you can always build your own custom image later Jul 04 20:04:30 that crashcourse site has instructions for doing that too Jul 04 20:04:33 somewhere. Jul 04 20:05:17 well as RCN would say, patches are welcome ;) Jul 04 20:07:20 "Its not that it doesn't work at all, it does, but for now you cannot boot from the SD-Card without holding down the boot button." Jul 04 20:07:22 Let's see if I like angstrom or even can get it to work at all, first. :) Jul 04 20:07:30 thats not rigth _Sy_ . . . Jul 04 20:07:31 heh Jul 04 20:07:45 If I knew where the script was being run (there doesn't seem to be anything like /etc/rc.local or /etc/rc.init) Jul 04 20:07:53 then it would probably be trivial to capture the output. Jul 04 20:08:15 Which would be good, because in case of error, the script sets the LEDs off (I assume echo none > /sys/class/leds/beaglebone\:green\:usr0/trigger means off?) Jul 04 20:08:26 and echos "ERRORS found: ${ERROR}" Jul 04 20:08:36 which would be really helpful to see if you actually had errors. Jul 04 20:08:51 yes that turns the leds off Jul 04 20:08:52 (In my case, the LEDs all came on, so it didn't think there were errors.) Jul 04 20:09:09 when you get a chance after logging in, cat that file Jul 04 20:09:31 it will also give you a clue how to get ride of the flashing led if that annoys you Jul 04 20:09:37 get rid of* Jul 04 20:09:38 I've been catting it, but I have no easy way of getting it onto another machine. Jul 04 20:09:52 ? Jul 04 20:09:53 (I guess I could copy/paste screenfull by screenfull.) Jul 04 20:10:09 you lost me Jul 04 20:10:11 mru, hwbug is sooo much fun :) Jul 04 20:10:38 26-26-54, I assume Jul 04 20:10:39 akk, not sure i know what you mean, but ssh ftw . . . Jul 04 20:10:52 after you're logged in of course Jul 04 20:11:00 the main site is more serious Jul 04 20:11:02 yes Jul 04 20:11:14 m_billybob: The script is on the beaglebone which is busy running it, but I have no way to copy it onto my desktop machine, or upload it or anything. Jul 04 20:11:21 sorry 26-26-54 Jul 04 20:11:42 There's no ssh. Hoping to get ssh is the reason I'm doing this re-flash in the first place, remember? :) Jul 04 20:11:53 akk, I use putty on windows . . . so much easier i guess but you can also log it Jul 04 20:11:56 The angstrom shipped on the BBB can't do it. Jul 04 20:12:07 can't do what? Jul 04 20:12:09 ssh Jul 04 20:12:10 akk i use putty for the serial debug console Jul 04 20:12:17 akk, seriously??? Jul 04 20:12:22 ka6sox: seriously Jul 04 20:12:23 i also log my putty sessions Jul 04 20:12:32 hmmm.... Jul 04 20:12:40 ka6sox: Apparently it's a bug and at least a couple people say flashing to a newer angstrom fixes it. Jul 04 20:12:42 I am currently ssh'd into 2 BBBs running Angstrom Jul 04 20:12:58 ka6sox its a common problem Jul 04 20:13:06 wulfman my buddy experienced it initially as well Jul 04 20:13:15 m_billybob: I have screen running under xterm ... maybe there's a way to get screen to capture output, but I don't know how. Jul 04 20:13:28 m_billybob: I log your putty sessions Jul 04 20:13:32 akk pipe ? Jul 04 20:13:37 Jul 04 20:13:43 mru good two sets of eyes better than one ;) Jul 04 20:13:46 Oh, sure, if I'd run screen under script or something I'd have a log. Jul 04 20:13:56 I guess I could disconnect and reconnect now, but I'm a little nervous doing that Jul 04 20:13:58 * ka6sox rolls eyes Jul 04 20:14:01 in the middle of an hour-plus operation Jul 04 20:14:58 (also I can never remember how to get screen to disconnect other than killing it from another terminal -- screen isn't very user friendly) Jul 04 20:15:23 mru, so question uEnv.txt has total control over how the bbb boots right ? no matter whcih distro you're running ? Jul 04 20:15:54 im under the impression that all distros use the same version of uboot Jul 04 20:15:57 u-boot runs before any distro Jul 04 20:16:28 ok so you made me answer my own question good. Jul 04 20:16:30 My uboot wasn't running at all, though. Jul 04 20:16:38 question would be yees then Jul 04 20:16:41 err answer Jul 04 20:16:43 The files were there on the partition, but the booting part wasn't working. Jul 04 20:17:20 mru was still unclear as to whether all images used the same uboot or not Jul 04 20:17:33 clarified now though Jul 04 20:18:07 I suspect that when I was booting off the SD card, I was actually using a uboot from the SD card Jul 04 20:18:15 since the one on the emmc wasn't running Jul 04 20:18:16 I did not say either way on that Jul 04 20:18:19 but maybe that's wrong. Jul 04 20:18:30 mru ok so clalrification still needed ;) Jul 04 20:19:09 geez, it's still running gnome settings and gconftool. Jul 04 20:19:18 I so need a cmdline distro that doesn't have gnome ... Jul 04 20:19:21 play by play ? Jul 04 20:19:34 yeah its not console image Jul 04 20:19:52 im not sure which one of those images koen has is the actual console image assuming he even has one Jul 04 20:20:12 Sorry if you don't want the play by play. Just that it's been doing gnome/gconf setting for 18 minutes now. Jul 04 20:20:26 No wonder this flashing business takes so long. Jul 04 20:21:28 Why would anyone want to run gnome on a lightweight board like this anyway? Jul 04 20:29:59 Hi everyone! Jul 04 20:30:42 akk: why would anyone want to run gnome? Jul 04 20:31:47 mru: Good point! I don't even on big fast machines. Jul 04 20:32:21 it's good in some cases, well-designed, but may be resource-intensive and unstable in some situations Jul 04 20:32:54 It seems to be finally through gnome proper, and now it's just running gtk-update-icon-cache for a gazillion individual apps. Jul 04 20:33:50 gnome has been all downhill starting with 1.4 Jul 04 20:34:06 * akk wonders why this is all being done as a script, rather than just copying a filesystem image onto the device Jul 04 20:34:59 Woo! It's done. LEDs lit, 1:06 total time. Jul 04 20:37:44 lxde ftw Jul 04 20:37:47 I'm just gonna get my new BeagleBone Black in a few days! I'm so excited... Jul 04 20:37:51 akk and now what ? Jul 04 20:38:48 Letting it sit unpowered for a minute or two, just in case ... Jul 04 20:38:59 That's probably long enough, trying ... Jul 04 20:39:17 Looking promising -- we have uboot Jul 04 20:39:24 and we have kernel messages Jul 04 20:39:53 and a login prompt, with those two errors I saw earlier when booting off the sd card Jul 04 20:40:10 so now if you still cant log in via ssh you can fix it Jul 04 20:40:17 but you could have fixed it earlier too Jul 04 20:40:27 From the web page? Jul 04 20:40:41 log in ssh through eth, it will work Jul 04 20:40:46 I forgot to plug in the mini usb cable, so I'm going to reboot to add that and see if the network works. Jul 04 20:40:48 mounting the s card on your linux box, then deleting / editing that one file i forget the name of Jul 04 20:42:04 eek, and then go through this whole 1:06 reflash yet again? Please no. Jul 04 20:42:15 no no no Jul 04 20:42:30 Oh, wait, you were talking about initially. But there was no SD card initially. Jul 04 20:42:41 without a serial debug cable you could have just popped the sd card out put it in your desktop/laptop and edited the file Jul 04 20:43:11 of course you'd have to know the name of the file whcih i cant remember either, but its in relation to dropbear Jul 04 20:43:12 There was no SD card. The issue was the distro shipped on the emmc. Jul 04 20:43:24 scrap dropbear Jul 04 20:43:24 ah yeah right lol my bad . . . Jul 04 20:43:25 now Jul 04 20:43:36 mru scrap angstrom too ? Jul 04 20:43:48 yeah im kidding Jul 04 20:43:56 openssh-server ftw Jul 04 20:44:26 dropbear is nice because it works on uclinux Jul 04 20:44:32 but we're not running uclinux Jul 04 20:44:33 Yay! ssh works now Jul 04 20:45:13 openssh-server isnt all that big . .. Jul 04 20:45:34 It's a lot smaller than the whole gnome desktop, for example. :) Jul 04 20:45:35 openssh-server is not difficult... Jul 04 20:45:38 heh Jul 04 20:45:43 definately pales in comparrison to gnome X11 and al that other un needed garbage Jul 04 20:45:45 m_billybob: no, but it doesn't work on uclinux Jul 04 20:45:51 needs a full mmu system Jul 04 20:46:50 what does angstrom have to do with uclinux ? Jul 04 20:46:54 nothing Jul 04 20:46:59 .... Jul 04 20:47:14 uclinux is an RTOS right ? Jul 04 20:47:18 no Jul 04 20:47:22 not by far Jul 04 20:47:30 uclinux is linux for nommu systems Jul 04 20:47:40 which is generally a bad idea Jul 04 20:47:53 but occasionally convenient for development Jul 04 20:47:57 Are there any RTOSes people are using on beaglebones? Jul 04 20:48:03 qnx runs ok Jul 04 20:48:07 speaking of whcih was just reading an article on a new arduino project that runs linux . . . Jul 04 20:48:39 There's some new arduino-paired-with-arm board, where the arm part runs linux. Jul 04 20:48:58 linux can't possibly run on an 8-bit avr Jul 04 20:49:13 (arm emulator running on avr doesn't count) Jul 04 20:50:13 article i was reading was talkign about some arduino project that does wireless ? or wired lan Jul 04 20:50:36 its in an actual dead tree magazine which isnt with me at this moment Jul 04 20:51:23 personally i think running an OS no mater if RTOS or not is a silly idea Jul 04 20:51:31 on that type of a device Jul 04 20:52:54 but the article was talkign about DDWRT or somethign like it Jul 04 20:53:30 It's nice to have things like python libraries, camera drivers etc ... yet still have good GPIO, analog input etc. Jul 04 20:53:57 <_av500_> the new arduino Jul 04 20:54:08 <_av500_> its an atheros wireless chipset plus an avr Jul 04 20:54:10 Before the BBB came out, it made sense to want an arduino-based board like that. Jul 04 20:54:19 <_av500_> the atheros runs openwrt Jul 04 20:54:45 koen, still here? Jul 04 20:58:29 Has anyone has enabled the DSP Bridgedriver for beagleboard xm running android Jul 04 20:58:52 <_av500_> rowboat? Jul 04 21:00:03 yes rowboatandroid Jul 04 21:00:17 i just download and test Android 4.0.3 ICS Jul 04 21:00:54 and it's working fine but when trying to enable the DSP following this steps http://android.serverbox.ch/?p=167 Jul 04 21:01:01 i just got stuck Jul 04 21:01:31 when i try to do make menuconfig i don't find de DSP Bridge i don't know how to enable Jul 04 21:10:28 didn't dspbridge follow nokia to the grave? Jul 04 21:11:12 not immediately unfortunately Jul 04 21:11:32 damn zombie drivers Jul 04 21:14:20 well i guess i'll died trying Jul 04 21:15:27 <_av500_> I think rowboat is from the TI fraction that does not recognize the DSP Jul 04 21:15:43 <_av500_> they only talk to it via the swiss embassy Jul 04 21:16:01 _av500_, the TI factions remind me of the local leftist factions Jul 04 21:16:17 and People Front of Judea Jul 04 21:16:44 the Judean People's Front is so much better! Jul 04 21:17:49 that's for the roman governor to decide Jul 04 21:20:23 working on driver for I2C barometer, and have most of it working, but two of the calibration coefficients values return as "None" Jul 04 21:21:56 like this ./i2cTest.py coefficient a0 = None coefficient b1 = -2.44519042969 coefficient b2 = -0.973815917969 coefficient c12 = None Padc: 0397 (0x018D) Tadc: 0501 (0x01F5) Jul 04 21:23:47 <_av500_> no i2cTest.py on my machine Jul 04 21:24:29 <_av500_> was bridge mainline? Jul 04 21:24:45 i named that file for testing the barometer Jul 04 21:25:21 <_av500_> ah staging Jul 04 21:25:29 <_av500_> Joematz: check again Jul 04 21:26:48 sorry which one? Jul 04 21:27:12 <_av500_> in staging Jul 04 21:27:19 <_av500_> driver->staging Jul 04 21:27:22 <_av500_> dspbridge Jul 04 21:28:28 Yeah i just seached that route but i don't have any dspbridge. My kernel is 2.6.37 Jul 04 21:28:53 * panto sputters Jul 04 21:28:54 And i don't know is that before trying to find it i hace to install that module Jul 04 21:29:01 have** Jul 04 21:31:32 http://pastebin.com/rrHYqzfn Jul 04 21:31:44 http://pastebin.com/7SzxcUtp Jul 04 21:31:54 <_av500_> 2.6.37? Jul 04 21:32:02 <_av500_> oh Jul 04 21:32:03 that's the class and test script for the I2C barometer Jul 04 21:32:41 <_av500_> Joematz: again, rowboat is from the TI fraction that does not know about the DSP Jul 04 21:33:13 <_av500_> it might well be that their .37 evil vendor kernel does not have bridge Jul 04 21:34:29 hey good new Jul 04 21:35:34 <_av500_> https://code.google.com/p/rowboat/wiki/DSP#Building_and_Testing_DSP_stack Jul 04 21:35:41 <_av500_> so they do know about the DSP Jul 04 21:36:12 <_av500_> ignore all I said Jul 04 21:36:14 knowledge does not imply acceptance Jul 04 21:36:20 <_av500_> true Jul 04 21:38:55 hey rowboat does recognize the DSP Jul 04 21:39:17 it's just matter of have well configure the kernel for the correct target Jul 04 21:39:33 thanks _av500_ Jul 04 21:40:21 <_av500_> mru: do you read this guy: http://ewontfix.com/11/ Jul 04 21:40:45 <_av500_> ah its felker Jul 04 21:40:51 <_av500_> ringsa bell Jul 04 21:42:23 felker is silly Jul 04 21:43:10 <_av500_> ah Jul 04 21:49:36 Where's a good pinout diagram for the header pins? I'm seeing conflicting info on various websites. Jul 04 21:50:16 akk: the technical reference manual? Jul 04 21:50:20 Like, http://learn.adafruit.com/setting-up-io-python-library-on-beaglebone-black/gpio says P8_10 is GPIO 26 Jul 04 21:50:27 but http://letsmakerobots.com/node/37063?page=2 says it's sys reset. Jul 04 21:52:05 http://elinux.org/BeagleBone#P9_and_P8_-_Each_2x23_pins possibly Jul 04 21:52:43 Is the pinout the same for BeagleBone and BeagleBone Black? Jul 04 21:52:53 http://beagleboard.org/static/beaglebone/a3/Docs/Hardware/BONE_SRM.pdf Jul 04 21:52:56 Looking at the reference manual, but it's 120 pages of PDF, so I haven't found anything there yet. Jul 04 21:53:18 what a puny manual Jul 04 21:53:32 a proper reference manual is at least 3000 pages Jul 04 21:53:48 you mean like the trm ? Jul 04 21:53:59 Silly me for thinking someone might actually have a pinout directly on the web somewhere. Jul 04 21:54:01 for example Jul 04 21:54:09 the AM335 manual is big Jul 04 21:54:21 not as big as the omap4 manual Jul 04 21:54:32 it's 4000 and some pages Jul 04 21:55:00 the am335x TRM is over 4100 pages Jul 04 21:55:19 ah right, it is Jul 04 21:55:38 the omap3 one is a bit over 3k Jul 04 21:55:57 spruh73c is 4593 pages, in fact Jul 04 21:56:27 I consider anything over 500 pages as "dahmed large" Jul 04 21:56:44 "too big to lern in an hour or two " Jul 04 21:56:59 learn too but yeah Jul 04 21:56:59 too big to fail Jul 04 21:57:29 just wish there some somethign like an SDRM Jul 04 21:57:44 read: something geared more towards developers Jul 04 21:57:51 software type Jul 04 21:57:57 that's the trm Jul 04 21:58:46 The TRM doesn't seem to have an actual diagram, but it has a table ... what are "Mode0" through "Mode7" ? Jul 04 21:59:11 akk supposedly Derek Molloy tossed together a table of both headers Jul 04 21:59:22 ive yet to find it on his site Jul 04 21:59:32 but he mentions it in his latest youtube video Jul 04 22:00:15 you should see the 'integration manuals' for the arm cores Jul 04 22:00:27 think ill pass for now Jul 04 22:00:29 (they're not public) Jul 04 22:00:50 and they're only of interest if you've licensed a core anyway Jul 04 22:01:08 so have you ? Jul 04 22:01:14 no Jul 04 22:01:17 I work for ARM Jul 04 22:01:32 truely. Jul 04 22:01:49 that must be an interrresting job Jul 04 22:02:06 guess ill have to refrain from bashing ARM while you're around ;) Jul 04 22:02:20 I work on open source stuff Jul 04 22:02:51 ah so mranostay is kind of an Intel counterpart to you then Jul 04 22:03:09 are you calling me a troll? Jul 04 22:03:18 no . . . Jul 04 22:03:39 from memory thats what he does at Intel. open source stuff Jul 04 22:04:00 I doubt he does much of anything yet Jul 04 22:04:03 he only just started Jul 04 22:04:39 yes, his soul hasn't been ground to a fine dust yet Jul 04 22:04:47 hehehe Jul 04 22:04:59 panto: he has a soul? Jul 04 22:05:24 figuratively Jul 04 22:07:16 Oh sheesh, the diagram I was following reversed the names for P8 and P9. *eyeroll* Jul 04 22:23:42 souls are for the weak. Jul 04 22:55:02 How can I find out which pins I can use for PWM output? Jul 04 22:55:57 I've read that there are 8 PWM pins. If I look in the tables in the SRM, there are 12 pins on P8 and 13 on P9 with "pwm" somewhere in their descriptions. Jul 04 22:56:21 I'm not clear what all the abbreviations mean or what the various modes are. Jul 04 23:56:52 Is the bbb gpio 3v3 or 5v Jul 04 23:59:56 3.3 Jul 05 00:14:13 morning earth Jul 05 00:14:22 mornin Jul 05 00:14:43 亚洲 Jul 05 00:18:10 aaa Jul 05 00:18:15 test Jul 05 00:18:40 05 simple Jul 05 00:19:07 05simple Jul 05 00:38:49 a?
