**** BEGIN LOGGING AT Mon Jan 15 03:00:01 2018 Jan 15 06:19:50 needHelpSerial: np, but please just use the channel rather than sending private messages Jan 15 06:20:05 Hi @zmatt , thanks for your help last night with serial port read/write issue. I am able use serialport module instead of bonescript. Jan 15 06:20:12 sure thanks :-) Jan 15 07:58:36 I just downloaded the latest Debian version and uploaded it to BBB. apt-get won't work because it keeps saying chromium-common needs to be fixed but when i do apt fix, it continues to fail. anyone have any ideas? Jan 15 07:59:06 of course chromium doesn't work because of this either when i vnc to BBB Jan 15 08:18:35 hello ,how to replace the kernel of the Debian system(BBB) Jan 15 08:19:23 I have make my own dtb、modules、zimage, Jan 15 08:19:43 可以讲中文吗 Jan 15 12:39:50 Hello Jan 15 12:40:19 hi Jan 15 12:41:08 I am trying to boot kernl via uboot, tftpboot. but nothing happens after Starting linux kernel... Jan 15 14:38:52 wtf, the wl1835 crashed according to kernel log Jan 15 14:46:22 well, it's a fat mac, I'd be very surprised if the firmware was bug free :) Jan 15 14:53:26 but... but... I wasn't doing anything remarkable at all Jan 15 14:54:32 not even trying to use bluetooth, GPS and wireless lan at the same time? Jan 15 15:00:56 nope, just wifi client mode, and the last crash actually seemed to happen at a really random moment while everything was completely idle: https://pastebin.com/raw/uJ4thv9j Jan 15 15:01:49 wow, it's resetting over and over again Jan 15 15:02:15 zmatt: custom hardware? correct firmware binary loaded? Jan 15 15:02:20 the second one happened pretty much after the first reset yeah Jan 15 15:02:56 the last one was more than 38 hours later Jan 15 15:03:12 bbbw with latest firmware binary from TI Jan 15 15:04:13 another bbbw where I've been doing much crazier things (AP mode and such) has had no such issue Jan 15 15:04:45 "thou shall check supply voltages" Jan 15 15:05:41 (pronounced with a thick aussie dialect) Jan 15 15:08:56 both bbbw's are powered via usb Jan 15 15:20:21 hmm, apparently there are people seeing crashes related to power-save modes Jan 15 15:33:13 oh, that rings a faint bell in the back of my mind... Jan 15 15:35:09 zmatt: do you also load a bluetooth init "script"? Jan 15 15:35:17 nope Jan 15 15:35:48 I don't use any of the weird custom startup scripts that were on the bbbw Jan 15 15:50:27 ok this is really weird, I've rebooted both of them, and again the same bbb had a crash after about 10 minutes Jan 15 15:51:34 and both are associated to the same AP, I guess Jan 15 15:51:42 and with identical configuration Jan 15 15:52:26 no, bbbw-2 (the non-crashing one) is in AP mode, and currently also simultaneously connected to the office wifi (it wasn't during earlier crashes) Jan 15 15:52:31 while bbbw-1 is connected to bbbw-2 Jan 15 15:52:55 nice configuration Jan 15 15:52:56 so maybe the wl18xx in AP mode is doing fancy power management stuff that's causing the other wl18xx to bork out Jan 15 15:53:14 lemme check this theory by swapping their roles Jan 15 15:54:27 If I connect a beaglebone black revision c to an ubuntu notebook by usb cable I do not get to access the bbb from the notebook. Maybe it is the usb cable. Lack of power to the bbb may also be an option? Can I 5v dc power supply the bbb while it is connected to the notebook? If so, in what order do I connect? Do I turn on the 5v dc bbb power supply before connecting the bbb to the notebook by usb cable? Jan 15 15:54:57 if you happen to have a good contact to the TI wireless people, I remember them debugging a similar issue with powersave I had while working in consumer electronics "back in the days" Jan 15 15:55:31 if it turns out to be powersave related, I'll probably just turn powersave off Jan 15 15:55:50 and maaybe report it via e2e if I manage to overcome laziness Jan 15 18:39:36 flj: Do you see anything when you run journalctl -f while plugging in the USB? Jan 15 18:41:29 Thanks. Is that journalctl -f in command line on the notebook? Jan 15 18:49:28 yeah Jan 15 18:49:44 because the bbb should give your laptop an internal IP on the USB device Jan 15 18:52:26 and a udev rules file may help, see this guide here https://learn.adafruit.com/ssh-to-beaglebone-black-over-usb/installing-drivers-linux Jan 15 19:00:13 Command line journalctl -f results in 'command not found'. Jan 15 19:02:44 hm I thought Ubuntu was systemd based so it should have journalctl... what version of ubuntu do you have? Output of lsb_release -a ? Jan 15 19:05:50 $ lsb_release -a Jan 15 19:05:50 LSB Version: core-2.0-amd64:core-2.0-noarch:core-3.0-amd64:core-3.0-noarch:core-3.1-amd64:core-3.1-noarch:core-3.2-amd64:core-3.2-noarch:core-4.0-amd64:core-4.0-noarch:core-4.1-amd64:core-4.1-noarch:security-4.0-amd64:security-4.0-noarch:security-4.1-amd64:security-4.1-noarch Jan 15 19:05:50 Distributor ID: Ubuntu Jan 15 19:05:50 Description: Ubuntu 14.04.5 LTS Jan 15 19:05:51 Release: 14.04 Jan 15 19:08:28 can you also run `which journalctl` Jan 15 19:08:48 and `dpkg -L systemd | grep journalctl` Jan 15 19:11:15 In command line which journalctl does nothing. Jan 15 19:11:21 by the way you might consider upgrading your ubuntu to 16.04 if you want LTS or 17.04 your version is pretty old Jan 15 19:12:46 $ dpkg -L systemd | grep journalctl dpkg-query: package 'systemd' is not installed Use dpkg --info (= dpkg-deb --info) to examine archive files, and dpkg --contents (= dpkg-deb --contents) to list their contents. Jan 15 19:13:17 so go with `tail -f /var/log/syslog` ... thats the old way to follow your log. Or check syslog manually. Point is to figure what your logging systems puts out when you plug in the powered-up bbb Jan 15 19:21:55 If I write tail -f /var/log/syslog in command line, a lot of data gets listed. I am not skilled enough to determine if I should paste it into irc. Jan 15 19:22:56 I have a debian 9 main computer. Should I try your commands on the debian 9 computer? Jan 15 19:23:12 I also have a debian 9 computer. Jan 15 19:35:57 Hey there, I'm trying to get my old beagleboard xM working again (using the latest available kernel image). Unfortunally it doesn't even properly start the kernel. When connecting it via serial I get this output: https://pastebin.com/pY6xzx9n Jan 15 19:36:49 I would be glad about any ideas, I couldn't really find anything useful using the error messages :( Jan 15 19:41:43 I meant debian image, not kernel image ( this one: https://debian.beagleboard.org/images/bbxm-debian-8.6-lxqt-xm-4gb-armhf-2016-11-13-4gb.img.xz ) Jan 15 20:15:47 flj: yeah debian 9 is what I have. You can also try `tail /var/log/syslog | grep USB` or so Jan 15 20:18:25 I tried command line sudo journalctl -f on the debian 9 computer. I was not able to understand the output. Jan 15 21:28:09 Forsaken|GER: hmm, the image linked to at bbb.io/latest-images is 2016-11-06, not 2016-11-13 Jan 15 21:28:34 zmatt Jan 15 21:28:38 I tried both Jan 15 21:29:23 if the one listed at latest-images doesn't even boot on the xM, I'd say it's definitely time for an annoyed email to rcn. I'm pretty sure those images are *supposed* to be tested :P Jan 15 21:29:24 not exactly a bbb question: is it possible to pull all the code for yocto without running a build? i have a yocto settup for bbb but i don;t want to run the build, i just want to pull all the code Jan 15 21:30:55 Forsaken|GER: based on your kernel log, it looks like something seriously wrong with the DT Jan 15 21:32:38 zmatt: DT? I'll try the 2016-11-06 one and check the serial log. I only checked the hdmi output for that one (a dozen time reflashing the card). Maybe there's something more useful Jan 15 21:33:08 device tree Jan 15 21:33:17 you Jan 15 21:33:20 oops, ww Jan 15 21:39:06 zmatt: It's the same for 2016-11-06 :/ Jan 15 21:47:38 weirdly I made it beyond that point once (in about 50+ times) until it got stuck on a black background with a frozen cursor. Unfortunally I neither had my serial connected at that point nor was I able to get it (halfway) booting once again, even after resetting without changing anything. Jan 15 22:33:55 Well I found the "newest production image" from 2010 at https://elinux.org/Beagleboard:BeagleBoard-xM#Image_Files and some hint about Rev C (I got a BB xM Rev C1) Jan 15 22:33:58 "There is a new UBoot that is required for the Rev C board to properly identify it as a Rev C and to handle a couple of HW changes. This UBoot version should run on the Rev A and Rev B -xM boards as well." Jan 15 22:34:46 hmmm, does the xM load u-boot from SD card or NAND ? Jan 15 22:34:59 That image at least works, even it's buggy af. Maybe I can use the boot options from that image to get the newer one working. Jan 15 22:35:08 sd card, it doesnt have nand Jan 15 22:38:44 ah, was that just the classic beagleboard? Jan 15 22:42:42 yeah, seems so Jan 15 22:44:26 a relay to discord or something? I seem to be missing some sentences. Jan 15 22:50:25 zmatt: afaik it's the classic beagleboard with a bit faster cpu and more ram Jan 15 23:12:22 well copying over the uENV.txt didn't help anything either (neither did messing with the other parts of the boot section) Jan 15 23:13:14 guess my next best option is building myself Jan 15 23:53:21 Forsaken|GER: also be sure to check https://groups.google.com/forum/#!categories/beagleboard/beagleboard-xm if anyone has had similar problems, or post there otherwise Jan 15 23:53:54 zmatt: I did both already, but I think my post first has to be moderated Jan 15 23:54:01 ah Jan 15 23:55:34 https://groups.google.com/forum/#!category-topic/beagleboard/beagleboard-xm/lVBoFn7yeb0 sounds potentially relevant Jan 15 23:57:07 have you tried the 2018-01-05 image btw? Jan 15 23:57:32 2018? no didn't see anything that new Jan 15 23:57:54 thx for the hint btw. didn't find that thread Jan 15 23:58:34 https://elinux.org/BeagleBoardDebian#BeagleBoard_xM so, it's just a console image, but if it works you can always install gui stuff on top of that if you want it Jan 15 23:59:55 or if you can verify it works, installing that kernel package onto the lxqt image probably works Jan 16 00:00:44 oh never mind, there's an lxqt image that's even newer Jan 16 00:00:56 https://rcn-ee.com/rootfs/bb.org/testing/2018-01-14/stretch-lxqt-xm/bbxm-debian-9.3-lxqt-xm-armhf-2018-01-14-4gb.img.xz Jan 16 00:08:19 zmatt: well I have to try this tomorrow. I only have a cardreader on my laptop and left my charger in the office :O Jan 16 00:10:42 thx a lot for the help, I'll tell if it worked tomorrow. good night :) **** ENDING LOGGING AT Tue Jan 16 03:00:03 2018
