**** BEGIN LOGGING AT Mon Dec 03 02:59:59 2012 Dec 03 03:00:14 ah never mind i didn't see the divisor field Dec 03 03:33:10 Has anyone ever tried to use a 24bbp lcd on the bone? Dec 03 03:44:42 people are clearly not googling now Dec 03 04:05:32 I meant the people actively here, I have googled around, and I'm having a lot of trouble. There is no reference to any 24bpp displays in board-am335xevm.c Dec 03 04:07:40 My LCD shows the Angstrom boot prompt in green, and fb-test shows the wrong colors, but seemingly the correct image when I have my bpp set to 16, but I have it wired for 24bpp, when I try to set it to 24bpp, the boot prompt doesn't show up on my LCD and fb-test flickers and shows the wrong colors and a bunch of stuff it overlapping. Dec 03 04:25:35 * mranostay pokes jkridner_ Dec 03 04:29:38 anyone know which GPIO bank the PRU is connected too?

Dec 03 12:00:47 which board? Dec 03 12:00:59 Beagle Board xm Dec 03 12:01:05 ethernet is connected over usb there Dec 03 12:01:47 thanks for answering Dec 03 12:02:51 np, it's what we do Dec 03 13:13:22 Hi, where should I best modify .config before running "bitbake virtual/kernel -c compile .f" again for BeagleBone? Dec 03 13:55:36 Good morning everyone... I'm currently having some problems with my Beaglebone... Last Friday I used "shutdown now" to power off the card and unplugged the power cord. This morning, nothing… I was unable to boot the board. I've developed a custom cape with a XBee receptor and a GPS receptor. Normally, the board is powered by the cape. I tried to boot the board without the cape and by powering the board through the 5V port, and the D1 Dec 03 13:56:02 than a second. I'm using the A6 Revision of the board. Do you have some ideas for me? Thanks :) Dec 03 13:56:23 carl__, it is possible you fried the board Dec 03 13:56:43 can you try to boot with a known good mmc card? Dec 03 13:58:06 I thought of that, and I don't have another mmc card of 4gigs available... Dec 03 13:58:22 hmm Dec 03 13:58:34 a simple way to see if the board is fried is to remove the mmc card and power on Dec 03 13:58:45 what should happend ? Dec 03 13:58:48 *happen? Dec 03 13:58:57 if you see a string of 'CCCCC' in the serial port the cpu should be OK Dec 03 13:59:09 it's the rom loader Dec 03 14:01:46 I managed to fry the sdcard slot on a beagleboard xM (one of three xm boards I have). That board outputs rom loader chars on the serial port but won't accept any card that boots perfectly fine on the other two boards. Something to dig into a rainy day... :) Dec 03 14:02:02 No idea how it happened though. Dec 03 14:02:13 carl__, be sure you remove any capes or other devices plugged in to the expansion connectors when trying panto's suggestion Dec 03 14:02:22 ah, yes :) Dec 03 14:02:31 panto, lessons learned! Dec 03 14:02:45 right, don't let the magic smoke come out Dec 03 14:03:26 My point is it is always valuable to have at least one more known good unit/board/sdcard for testing... Dec 03 14:03:47 I just connected the board via USB, and no COM port showed up in the Peripheral manager. It seems like there is some kind of electrical protection, no? Dec 03 14:04:07 No capes are connected on the board right now Dec 03 14:04:26 jonand: nice way to double sales :) Dec 03 14:04:27 carl__, from the looks of it you fried it Dec 03 14:04:35 order_a_new_bone++ Dec 03 14:05:23 the usb console should show up even without the cpu working IIRC Dec 03 14:05:32 it's an FTDI chip Dec 03 14:06:22 yes Dec 03 14:07:13 carl__, post issue to the beagle list and and file an RMA Dec 03 14:08:50 another test could be to power the board via the 5V connector instead of the USB connector? Dec 03 14:09:36 you could try that too Dec 03 14:38:17 okay, i just tested to power my beagle with the 5V adapter... Same behavior with and without the SD card: as soon as I plug the cord, the D1 Led blinks one time in less than a second... Dec 03 14:38:59 And nothing else happens... The board does not boot. Dec 03 14:39:24 What could have damaged the board ? Dec 03 14:44:30 TechNexion "Putting Huge Things in Tiny Places" with thier flagship product the 7" MultiTouch Kit Dec 03 14:44:34 http://www.technexion.com/index.php/about-us Dec 03 14:45:04 You couldn't make it up! ;) Dec 03 14:45:40 jackmitchell: can i have one with cream and one with chocolate, please? Dec 03 14:50:41 Thanks for the answers guys... I have one last question: I power the bone through the cape, is there any precautions I should take on my cape to avoid having another board fried? Dec 03 14:53:12 don't exceed 5.2 volts Dec 03 14:57:23 I'm having a big problem with my BeagleBone restarting about 1 minute after booting. I don't do anything with it. I'm just watching the serial output: http://pastebin.com/d2uzPaeR It seems to be ~ 60 to 90 seconds after boot, and it's only happening about half the time. I've also tried multiple boards, so I know it isn't the board itself. Anyone know what I can do to get verbose output? or find out wtf Dec 03 14:57:23 is going on? Dec 03 15:08:35 clockman, are you powering over USB? Dec 03 15:08:50 yes Dec 03 15:09:01 i've tried over 5v psu too though Dec 03 15:09:13 does it reboot with the 5v psu too? Dec 03 15:09:53 it did, but i also had the usb plugged in Dec 03 15:10:03 lemme go find the 5v psu and i'll check without the usb plugged in Dec 03 15:12:53 first try, not rebooting... i'll wait about 1 more minute and try again Dec 03 15:16:38 second reboot seems okay Dec 03 15:16:56 trying a third boot Dec 03 15:19:32 well usually by now, it'll have happened. Dec 03 15:19:39 but it seems okay now Dec 03 15:19:52 think my usb isn't supplying enough power or something? Dec 03 15:20:01 or is noisy? Dec 03 15:22:10 it might not supply enough power Dec 03 15:22:18 hi prpplague Dec 03 15:22:39 well, i shall power off 5v psu from now on. thanks guys Dec 03 15:24:18 Does anyone confirms the input voltage range from P9 or have preconisations ? I filed an RMA, but I don't want to problem to happen again... Dec 03 15:25:31 which pins? Dec 03 15:29:14 mru: bang all the pins Dec 03 15:31:25 one more question. which takes precedence? USB power or 5V DC power jack? if I plug in the dc jack first, will I then be able to plug in usb and it won't switch over power to the usb? Dec 03 15:39:22 panto: greetings Dec 03 15:40:03 mind if I send you the ELC CFP before I sent it out? Dec 03 15:40:05 Hey, I'm trying to debug something on the beaglebone, and gdb is giving me errors when I try to connect to openocd: http://paste.debian.net/214110/ Dec 03 15:40:41 I tried both the version that comes with debian (0.5.0) and one I compiled from source (0.6.1), but I get the same results Dec 03 15:41:34 panto, bitbanging unicorns? Dec 03 15:41:53 bitbanging DT unicorns! Dec 03 15:42:09 ooh, I'd drive out to see that if I had to Dec 03 16:04:43 mranostay, the 8ball requests you repeat your PRU gpio question Dec 03 16:31:05 http://www.hardkernel.com/renewal_2011/products/prdt_info.php?g_code=G135341370451 I like the "case" Dec 03 16:32:40 i personally find the address line more entertaining Dec 03 16:32:57 "704 Anyang K-Center, Gwanyang, Dongan, Anyang, Gyeonggi, South Korea, 431-815" Dec 03 16:33:24 how many words ending with "ang" do you know and can you put into one line? ;) Dec 03 16:33:41 it's a common suffix in korean Dec 03 16:33:42 actually they end in yang Dec 03 16:34:04 mru: probably. Dec 03 16:34:31 i just find it amusing that they seem to need 4 levels of indirection to get to the street. Dec 03 16:35:16 not all of them are strictly necessary Dec 03 16:35:31 where is ying at? Dec 03 16:35:32 (ok, that the cooling block is two times the size of the board is worth a smile too ;)) Dec 03 16:36:27 couldn't they have integrated cooling in the usb/eth jack? Dec 03 16:37:02 i suspect that would need engineering and not only taking reference schematics and cutting the BOM in half. ;) Dec 03 16:38:31 http://26-26-54.hardwarebug.org/45 Dec 03 16:38:47 hrhrhr Dec 03 17:10:30 My previous issue concerning beaglebone and gdb was simply that I was trying to connect gdb to the telnet port of openocd :( Dec 03 18:14:27 djlewis: well how is our favorite AR programmer? Dec 03 18:15:01 hehee, your only AR programmer I know of ;) is well, thank you Dec 03 18:15:23 just tossed 5 more computers in the dumpster this morning.

Dec 03 21:16:36 mranostay, that's typical there? Dec 03 21:29:14 prpplague: just curious. how do women in barbados view trolling?

Dec 03 22:03:25 heh Dec 03 22:03:30 mdp: if you could latch with the shift out mode that would be awesome Dec 03 22:03:48 * mranostay makes that a note for his slides Dec 03 22:03:56 mranostay, there's several little tweaks I wish for in there Dec 03 22:04:12 mdp: i mean that would be perfect for shift registers then Dec 03 22:04:56 mostly as a reference due to the out-of-tree drivers and suboptimal approach..but you might find the pru "soft uart" implementation that's hanging out on gitorious of interest Dec 03 22:05:27 since they don't care about determinism, they grab the mcasp to use as a shift register for 1-4 UARTs Dec 03 22:05:35 mcasps Dec 03 22:06:25 https://gitorious.org/pru/am335x-pru-uart-fw Dec 03 22:06:50 heh Dec 03 22:07:22 mdp: i was thinking being insane and using the other pru's shift out as a latching output :) Dec 03 22:07:48 avoiding external logic? Dec 03 22:08:47 that seems sane Dec 03 22:09:03 you know you can directly drive the other pru's registers, right? Dec 03 22:09:06 that's what I did Dec 03 22:09:30 so look at it as you can have simple code on one pru and steal all the other pru's resources for your own Dec 03 22:10:35 recruiters are going wild on linkedin Dec 03 22:10:51 must need to connect to TIers to look at other TIers for plucking Dec 03 22:12:32 mranostay, https://gitorious.org/pru/am335x-pru-uart-fw/trees/master .. for a more involved use case Dec 03 22:14:51 a pruart! Dec 03 22:15:56 a plague of uarts upon thee Dec 03 22:16:22 9 Dec 03 22:17:37 8 Dec 03 22:20:01 11 Dec 03 22:23:00 Hmmmm Dec 03 22:24:12 mdp: know off hand if the PRUs can access the full I2C hardware in DMA mode? Dec 03 22:24:44 iiuc the pru has full L3 access Dec 03 22:25:22 not just access but with the DMA Dec 03 22:25:30 that would imply sharing the interrupts and a few other things Dec 03 22:25:33 which dma? Dec 03 22:25:52 the one from the DMA controller to main memory... system dma? Dec 03 22:30:41 ds2: looks like the pru can drive the edma Dec 03 22:31:38 mru: Hmmm this opens up possiblities Dec 03 22:32:33 will the pru feed my cat and wash my car? Dec 03 22:32:41 mranostay: is it an ethercat? Dec 03 22:32:52 maybe it will Dec 03 22:33:12 this is an ethercat: https://lh6.googleusercontent.com/-JCY6RWQ-PAw/UFchwDGUaFI/AAAAAAAACYQ/4jYhbcy-j7A/s420/ethercat.png Dec 03 22:34:55 pru can access everything Dec 03 22:35:36 mdp: are all system interrupts routed to the pru intc as well? Dec 03 22:35:41 ethercats, ho! Dec 03 22:36:15 mru, not sure..I think *some* at least Dec 03 22:36:25 bbl Dec 03 22:36:25 that was the question Dec 03 22:36:40 a glance at the trm says some edma interrupts are routed there Dec 03 22:37:07 but I also saw the phrase "select peripherals" Dec 03 22:37:12 but does access == exclusive or shared? Dec 03 22:37:19 i.e. I am responsible for avoiding collisons Dec 03 22:37:37 you'd have to make sure the a8 doesn't try to use the same dma channels Dec 03 22:37:47 right, but that's a sw thing Dec 03 22:37:56 vs a hard mux somewhere that prevents it Dec 03 22:38:03 probably the best approach is to make a linux driver reserve a channel and tell the pru the details Dec 03 22:38:24 or just tell Linux it has fewer channels Dec 03 22:38:33 or that Dec 03 22:39:13 I wonder if the PM bug can be solved by using a PRU instead Dec 03 22:40:49 we were taught at university that "there is no problem in computer science that cannot be solved with another level of indirection" Dec 03 22:41:01 this isn't exactly CS, but the rule might still apply Dec 03 22:43:14 as I understand it, part of the bug has to do with buggered firmware for a M3 something like that Dec 03 22:43:37 if giving up 1 PRU gives me suspend and resume... Dec 03 22:44:04 excpet the problem of having too many levels of indirection Dec 03 22:44:33 thurbad: that's a problem that doesn't exist in cs Dec 03 22:44:40 lol Dec 03 22:46:50 * mranostay breaks out the smoke and mirrors Dec 03 22:47:59 why you think some schools don't officially offer a CS degree and instead offer a "equiv" that looks a lot like a consolation prize for EE's who can't make it? Dec 03 22:48:00 :D Dec 03 22:48:40 ds2: better than a CIS one :) Dec 03 23:05:52 Question: I want to use my db9 port for controlling a GPS timer, but there is interference because of my console using ttyS2 Dec 03 23:06:18 I've disabled the getty for ttyS2, but it is still being designated to my console within Angstrom's bootargs Dec 03 23:06:36 cat /proc/cmdline reveals that ttyS2 gets taken by the console at boot Dec 03 23:06:39 so change the boot args Dec 03 23:06:51 is there a way to do this without rebuilding the kernel? Dec 03 23:06:53 hi mru Dec 03 23:07:40 as far as I can tell, the bootargs are hard coded. I've created uEnv.txt in my /boot directory as follows: Dec 03 23:07:47 there is ALWAYS a way of doing it w/o reuilding the kernel Dec 03 23:07:52 it gets loaded into RAM :) Dec 03 23:07:56 or u-boot Dec 03 23:08:14 if you like doing that way Dec 03 23:08:23 contents of /boot/uEnv.txt: console=ttyS3,115200n8 Dec 03 23:08:38 my u-boot files are binary Dec 03 23:08:47 ever heard of a hex editor? :) Dec 03 23:08:50 (trying not to recompile) Dec 03 23:09:01 just build naked images Dec 03 23:09:12 you can write a util to convert uImage to a naked image Dec 03 23:09:43 naked image. hmm this requires more research Dec 03 23:09:54 sounds like dirty talk to me ;) Dec 03 23:10:04 nobdoor: you just won a free pass to trollcon 2013 Dec 03 23:10:23 or wire in some NOR and run xip's Dec 03 23:10:51 ds2: but xip can't be patched at runtime Dec 03 23:11:06 why not? Dec 03 23:11:20 it is only NOR, not mask ROM Dec 03 23:11:35 patched non-destructively Dec 03 23:11:37 i'm suprised that there are so many hoops to jump through to use a serial port Dec 03 23:11:44 nobdoor: your question has been addressed here a lot in the past and more in the future. Dec 03 23:11:47 tried google? Dec 03 23:12:05 yes Dec 03 23:12:09 angstrom isn't really talked about Dec 03 23:12:14 mostly ubuntu solutions Dec 03 23:12:14 really it isn't? Dec 03 23:12:16 tried reading source code? Dec 03 23:12:17 odd Dec 03 23:12:34 angstrom solutions reccomend creating /boot/uEnv.txt Dec 03 23:12:41 and killing the getty Dec 03 23:12:55 this is not working for me. ubuntu solutions refer to different file trees Dec 03 23:13:27 upgrade Dec 03 23:13:31 you must be using obsolete stuff Dec 03 23:13:37 ideally I'd like to keep my os and save my work Dec 03 23:13:59 get another SD card Dec 03 23:15:13 that is the ideal case Dec 03 23:15:17 we don't live in an ideal world Dec 03 23:16:25 it would be insane for the beagleboard to be shipped without the ability to configure its serial port Dec 03 23:16:42 ideal is too strong of a word. this should be common sense :P Dec 03 23:18:16 it's perfectly possible Dec 03 23:18:36 but I'm starting to doubt that you're capable Dec 03 23:19:10 that's kind of rude Dec 03 23:21:57 trools have been known to be thus Dec 03 23:22:01 trols? Dec 03 23:22:06 trolls :) Dec 03 23:24:01 nobdoor: which BB do you have? Dec 03 23:24:04 heh Dec 03 23:24:21 beagleboard-xm rev C Dec 03 23:24:43 running 2.6.32 Dec 03 23:25:37 I was thinking of the older pre XM models. Not related here. Dec 03 23:30:35 later guys, dolls and trolls . . . Dec 03 23:30:57 c u Dec 03 23:49:51 mdp: doesn't msp430 have usb already? Dec 04 00:47:51 I am wondering if there is any way to run code on the host computer (in this case preferentially a mac) and access the i/o's on the beaglebone? The software I have been developing in c++ runs too slowly on the beaglebone, and all I really want is to send/receive signals to some simple hardwar (pager motor, accelerometer... and an fsr matrix). Dec 04 00:51:52 Any idea(s)??? I feel like there should be a way to have a library on the host computer that allows access to the beaglebone pins? Dec 04 00:53:40 Is this a stupid question? Have I missed a basic solution / understanding? Dec 04 01:06:22 I am wondering if there is any way to access the beaglebone I/O's from code running on the host computer when it is plugged in (in this case C++ on a Mac)? Dec 04 01:09:55 stop asking the same question Dec 04 01:15:30 Is there an answer (I am not sure if people who are joining new see the old questions)? Dec 04 01:43:39 Salal: yes of course there is an answer Dec 04 01:43:47 Salal: it is very easy to do Dec 04 01:44:07
