**** BEGIN LOGGING AT Sun Apr 19 02:59:59 2015 Apr 19 04:57:52 Ahh there we go, confirmed that serial connection LaunchPad from BeagleBone is feasible without additional hardware Apr 19 04:58:11 It was just that the code I was running was drawing WAY too much power (was running the qs-rgb example project) Apr 19 04:58:26 So, as long as I can use a seperate power source, I should be fine. Apr 19 09:30:29 Hi all! I'm looking for a bit of help, I have tried searching for the answer but my google foo is weak this evening. I want to know what creates the mount point /media/BEAGLEBONE/ on the BBB. Anyone know? Apr 19 09:31:24 I would like to make changes to the content and the name Apr 19 09:39:21 I would start out by grep -r /etc media Apr 19 09:51:02 any idea why my bbb does not load a kernel module specified in /etc/modules or modules-load.d/? Apr 19 09:52:43 the respective files contain(ed) simply the name of the modules (without the .ko) and the same string with modprobe works fine Apr 19 09:58:54 The output of grep -r /etc media is...

Apr 19 10:12:18 What mounts the 'Linux File-CD Gadget USB Device' 'BeagleBone Getting Started' (/dev/mmcblk0p1)? Apr 19 11:56:31 hi all Apr 19 11:56:52 anybody here? Apr 19 11:56:59 * GenTooMan nopes. Apr 19 11:57:00 have got question Apr 19 11:57:03 :D Apr 19 11:57:19 We are all unconcious ... really. Apr 19 11:57:27 I have got simcom 928 modem connected to uart4 Apr 19 11:57:31 :D Apr 19 11:57:34 wake up Apr 19 11:57:42 like I said, to uart4 Apr 19 11:57:48 only using rx and tx Apr 19 11:57:56 no rts no cts Apr 19 11:57:58 thats the 16c750 immitation uart? Apr 19 11:58:17 everything works fine, pppd connects, but when I try to download few megabytes zip Apr 19 11:58:19 bbb reboots Apr 19 11:58:29 probaby hungs up and watchdog restrts it Apr 19 11:58:40 hmm Apr 19 11:58:44 I am not sure Apr 19 11:58:51 if it is 16c750 Apr 19 11:59:27 for me it look like uart is overflowed,causes sysytem no hung up and watchod restarts it Apr 19 12:00:19 IF a UART overflows it should be reset (uart) but it depends on what they do. Zmatt was commenting on the UART yesterday. Apr 19 12:00:43 hmm Apr 19 12:00:45 know anything about linux drivers? :D Apr 19 12:00:51 that is the problem Apr 19 12:00:54 not too much Apr 19 12:00:59 expected this just to work Apr 19 12:01:00 :D Apr 19 12:01:17 ofcourse ppp is set up to use xonxoff Apr 19 12:01:23 modem is set up to use xonxoff Apr 19 12:01:38 evrything is fine Apr 19 12:01:43 until i try to download zip file Apr 19 12:01:48 OK did you test it on a PC Apr 19 12:02:01 nope Apr 19 12:02:11 IE hook the modem to a PC open up 2 sessions and transfer to the PC Apr 19 12:02:32 Well make sure XON and XOFF are the same on both ends. Apr 19 12:02:36 kinkazu proably a power problem? Apr 19 12:02:56 uart4 transfer with xon xoff? Apr 19 12:03:05 yes Apr 19 12:03:12 uart4 with xon xoff Apr 19 12:03:17 can;t connect to pC Apr 19 12:03:24 it is already dveloped board Apr 19 12:03:29 mad by electronic guy Apr 19 12:03:31 you mean a file transfer fails Apr 19 12:03:37 nope Apr 19 12:03:40 bbb restarts Apr 19 12:03:53 sometimes download 5% of 20mb Apr 19 12:03:59 sometimes 2% Apr 19 12:04:07 but ping works all the time Apr 19 12:04:07 what baud rate? Apr 19 12:04:09 ssh sesion all the time Apr 19 12:04:12 115200 Apr 19 12:04:20 but Apr 19 12:04:23 checked 57600 Apr 19 12:04:25 same thing Apr 19 12:04:36 what about 19200 and 9600? Apr 19 12:04:42 woglinde: power shouldn be a problem Apr 19 12:04:58 2.5 Amp psu Apr 19 12:05:14 or more even Apr 19 12:05:16 are you using minicom? Apr 19 12:05:17 4.5 Apr 19 12:05:19 maybe Apr 19 12:05:21 have to check Apr 19 12:05:25 yes Apr 19 12:05:30 to set up the modem Apr 19 12:05:34 minicpm works wfine Apr 19 12:05:42 but then I use ppp Apr 19 12:05:57 it dies on ppp? Apr 19 12:06:20 yes, but only when downloading big zip file Apr 19 12:06:27 yes on ppp Apr 19 12:06:50 have got ppp updated Apr 19 12:06:54 to lates version Apr 19 12:07:06 have even checked 2.4.7 Apr 19 12:07:15 which is no official Apr 19 12:07:21 same thing Apr 19 12:08:10 but it is interesting what you say Apr 19 12:08:22 i might try to download same file but without ppp Apr 19 12:08:25 for a start Apr 19 12:08:35 GenTooMan: the issue I was having was on too-fast transmit (without overflow), and it causes some garbage output but then recovers Apr 19 12:08:40 first I need to learn how to do this Apr 19 12:08:41 GenTooMan: overflow/underflow only drops chars Apr 19 12:09:06 yes, I would understand if zip is corrupted, transmissiion broken Apr 19 12:09:11 but bbb restarts Apr 19 12:09:16 PPP set up for XON XOFF? Apr 19 12:09:22 yes Apr 19 12:09:25 asyncmap correct Apr 19 12:09:26 sounds like a crash to me Apr 19 12:09:46 tried everything what could be tried in rgeards of ppp Apr 19 12:09:55 everysetting Apr 19 12:10:06 but yes, bbb crashes Apr 19 12:10:12 or hungs up Apr 19 12:10:27 Ok weird question time, did you get that to work across the regular network connection? Apr 19 12:10:30 and watchdog restarts it Apr 19 12:10:37 PPP settings are not going to cause a BBB to crash or reboot... that strongly suggests either a kernel bug or hw bug Apr 19 12:10:41 yes Apr 19 12:10:47 no problem over lan Apr 19 12:11:05 have access to the (serial) console? Apr 19 12:11:11 yes i do Apr 19 12:11:23 i can give you access to bbb Apr 19 12:11:29 if you wish to see it yourself Apr 19 12:11:31 :D Apr 19 12:11:40 need to set up router to forward port Apr 19 12:11:54 I just wanted to know if anything is visible there, like a kernel panic :P Apr 19 12:12:03 o Apr 19 12:12:11 will have to try it Apr 19 12:12:12 * GenTooMan grins. Apr 19 12:12:16 :D Apr 19 12:12:35 debug port is avaliable Apr 19 12:12:39 zmatt anyway the WD kicking might be reported? Apr 19 12:12:44 need to hook it up wth pc Apr 19 12:12:47 and observe Apr 19 12:13:01 where should I look for Apr 19 12:13:11 any info about this retsart Apr 19 12:13:20 kinkazu: observing what happens on the serial console should always be step 1 when experiencing a crash :P Apr 19 12:13:26 :D Apr 19 12:13:33 no idea how about not just observe but log all the stuff it reports tell it reboots as "normal" Apr 19 12:13:33 thanks Apr 19 12:13:36 I will be back in 10 mins Apr 19 12:13:53 it may spit out a LOT of stuff Apr 19 12:13:59 i will chcek debug console Apr 19 12:21:32 hopefully he'll log it (like I suggested) if not he may have to go and come back again cause he will miss something. Apr 19 12:22:12 long live screen -L Apr 19 12:24:45 :D Apr 19 12:24:50 have got something Apr 19 12:24:58 sec will pastebin Apr 19 12:26:34 http://pastebin.com/zxb0WZpu Apr 19 12:27:46 yyy Apr 19 12:27:49 :D have no clue Apr 19 12:27:59 what it says Apr 19 12:28:17 you're using CAN ? Apr 19 12:28:21 yes Apr 19 12:28:26 it crashed in there Apr 19 12:28:28 have got can hooced up as well Apr 19 12:28:32 on can? Apr 19 12:28:56 crashes on can? Apr 19 12:28:57 hmm, reentrent kernel? Apr 19 12:29:10 i am not reaidng anything Apr 19 12:29:13 can disable it Apr 19 12:29:19 and check again ppp Apr 19 12:29:28 ? Apr 19 12:29:36 next time please enable logging in your serial app instead of copy-pasting... either that or make your window _much_ wider Apr 19 12:29:40 the line breaks are annoying Apr 19 12:29:48 ok Apr 19 12:29:49 sec Apr 19 12:31:00 not entirely sure why I'm seeing ppp_asynctty_receive and CAN stuff in a single backtrace... might be normal for a reentrant kernel perhaps Apr 19 12:32:29 * GenTooMan cant' tell brain is twitching from all the line bbb bbb bbb breaks. Apr 19 12:33:51 sec Apr 19 12:33:52 ppp_asynctty_receive did _raw_spin_unlock_irqrestore, which instantly led to an irq being serviced for CAN Apr 19 12:33:55 will de again Apr 19 12:33:56 sorry Apr 19 12:34:13 but there it stops making sense to me Apr 19 12:35:04 ok, so those are separate task dumps Apr 19 12:37:28 it may be a good idea to collect more than one crash .. it could be that CAN is not related at all but just happened to be active at the moment the watchdog expired Apr 19 12:39:31 is the watch dog is kicked in the kernel idle thread? Apr 19 12:39:50 it's not really the watchdog anyhow but the softlockup timer Apr 19 12:39:56 will have another dump Apr 19 12:40:17 soon Apr 19 12:42:13 waiting Apr 19 12:42:27 sometimes it is after 100kb Apr 19 12:42:33 sometimes after 1mb Apr 19 12:43:10 what is system behaviour leading up to that point? everything seemingly normal right up to the lockup? or first signs of poor responsiveness? Apr 19 12:44:58 happens during downloading Apr 19 12:45:03 transfer drops to 0 Apr 19 12:45:05 6% [=> ] 1,422,826 --.-K/s eta 74m 29s Apr 19 12:45:09 and then Apr 19 12:45:12 not repsonsive Apr 19 12:45:14 cant log in Apr 19 12:45:24 after a few seconds Apr 19 12:45:28 ping to bbb stops Apr 19 12:45:33 so probably restart happens Apr 19 12:45:47 soft lockup by itself normally doesn't cause a reboot I think Apr 19 12:45:52 just a backtrace Apr 19 12:46:03 this time Apr 19 12:46:06 not much Apr 19 12:46:12 have been ouput Apr 19 12:46:16 to debug console Apr 19 12:46:19 only this Apr 19 12:46:21 beaglebone login: [ 1220.036826] BUG: soft lockup - CPU#0 stuck for 23s!

I tried installing Angstrom instead of stock Debian, but that didn't solve the problem. Apr 19 13:59:34 I can login into it via debug port and my computer still sees it as a storage device. Apr 19 14:05:09 why do you prefer angstrom? Apr 19 14:06:33 I don't. Installing a different distro was the only thing I could think of for solving the problem.

Apr 19 16:29:01 I can assure you, those are correct credentials for the current series of 'official' debian images :) Apr 19 17:28:35 I have searched for single blue light no boot.

Apr 19 18:35:10 tholm .. fudge ya kernel and/or create your own processor .. some of that is embedded in it. Apr 19 18:35:43 personally ..
