**** BEGIN LOGGING AT Mon Mar 25 03:00:06 2019 Mar 25 08:22:04 Hello, if I previously downloaded Debian 9.4 for my BBB and regularly do package updates (apt-get update, apt-get dist-upgrade), do I have the same system as current Debian 9.5 ? Mar 25 08:35:32 DVDR9: user-space wise, yes. You might want to check if your kernel is up to date Mar 25 08:39:01 tbr: thank you very much, I will check that Mar 25 10:38:25 Hello, Mar 25 11:30:40 Hi, i have a problem booting beaglebone (kernel panic) Unhandled fault: external abort on non-linefetch (0x1008) at 0xe09e2000 Internal error: : 1008 [#1] SMP THUMB2 Mar 25 11:36:47 hhhhh: "when doing what" Mar 25 11:43:09 We try to run linux from sd card, we got all four LEDs on, then only LED 2 stays on, and kernel doesn't boot. Debug log: https://www.linux.org.ru/forum/linux-hardware/14885231 Mar 25 11:44:50 hhhhh: try an up to date image. this is ancient. Mar 25 11:46:01 hhhhh: and what board etc.. Mar 25 11:49:42 Beaglebone black. We also tried latest debian image. It worked fine (both angstrom and debian images), but then bbb disconnected from PC and failes to boot both images Mar 25 11:50:21 hhhhh: well there's always the possibility that its broken. Mar 25 11:52:31 how can we diagnose it? where can be the problem? Mar 25 11:54:27 disconnect everything? what was the last thing that you did? Mar 25 11:59:52 we were debugging application with gdb from qt creator on PC Mar 25 12:02:12 then we lost connection, tried to reconnect then to reboot and the reboot failed Mar 25 12:03:07 put the sd card into another board and see if it works. if yes, then probably the board is broken. Mar 25 12:03:21 (easiest approach) Mar 25 12:04:43 yeah, but can i somehow find out what is broken and whether i can repair it? Mar 25 12:05:30 hhhhh: i'd say this is a chicken-egg problem. if you had the means to repair it, then you would also had the means of diagnosing Mar 25 12:05:49 but for a ~50$ board... Mar 25 12:06:33 hhhhh: there's always the possibility that jsut the sd card is busted, so be sure to try another one there too! Mar 25 12:06:50 i have two sd cards and bbb doesn't work with both Mar 25 12:07:23 well Mar 25 12:07:42 (its really complicated to get information out of you, hence i kinda will be quiet now.) Mar 25 12:08:17 thanks for the help Mar 25 13:01:50 we damaged eeprom CAT24C256W, how flash with usb and restore device ? Mar 25 14:19:30 fgggg: you mean you managed to erase/overwrite the board identification eeprom? oof Mar 25 14:22:11 On which board? Build a custom u-boot and boot it from an SD card. Mar 25 15:50:21 hello there, I'm trying the latest images for the beagleboard x15 boards and they're failing to boot. Also the naming scheme of the image files changed. does anyone have any info in this? Mar 25 15:51:32 @raffo, just booted on my x15, working on an email to you... it boots fine here, you should drop the "quiet" line from /boot/uEnv.txt to see what's really failing. Mar 25 15:52:00 the rename is due to: https://beagleboard.org/ai Mar 25 15:53:49 : /sbin/init: error while loading shared libraries: librt.so.1: cannot open shared object file: No such file or directory Mar 25 15:53:57 wonders if your microSD is corrupt.. Mar 25 15:59:07 I flashed multiple uSD cards, but I can recheck the images I downloaded. However, the 3/17 and 3/24 images have the same error. Mar 25 16:06:59 The downloaded image is ok. Re-flashing... Mar 25 16:25:39 same error. Mar 25 16:27:05 * rcn-ee[m] sent a long message: < https://matrix.org/_matrix/media/v1/download/matrix.org/whQNojtnAAYQSlDJchRoPTaD > Mar 25 16:27:25 does anything change when you remove the sata drive? Mar 25 16:28:19 No, I just tried that. Mar 25 16:35:45 I'm in the (initramfs) shell and i have librt.so.1 library: https://pastebin.com/S7KZ1sTY Mar 25 17:15:55 The am57xx-debian-9.8-console-armhf-2019-03-24-1gb.img.xz image boots. Mar 25 17:20:57 The image am57xx-debian-9.8-iot-armhf-2019-03-24-4gb.img.xz fails with: /sbin/init: error while loading shared libraries: libselinux.so.1: cannot open shared object file: No such file or directory Mar 25 17:22:10 On the booting image, what does: sudo memtester 512MB report? Mar 25 17:36:08 It finished Loop 1 w/o errors. Mar 25 17:36:53 I'm using these images with a AM572x EVM REV A.20 board now. Mar 25 18:09:11 It completed 3 loops w/o errors. Mar 25 20:04:01 This is very puzzling, my rev C board will boot the 3/24 OS image without errors from one of my uSD cards. An identical card will fail to boot with an error executing init, like above. However, this same "bad" uSD card will boot the image from 2/17/2019. Mar 25 20:39:25 unstable block that happens to contain essential data on one image and inessential data on another image Mar 25 21:32:35 you think it's a bad uSD card? so far 3 out of 5 work. Is there a way to test these uSD cards? Mar 25 21:37:26 Grab a new one, flash the same image, if the new one works, your old card is dead.. (i've got a bag full of dead ones) Mar 25 21:46:19 I think you are right. This has been all about flaky uSD cards. Mar 25 22:04:20 the way sd cards signal their end of life is not by giving any sort of actual error, but by toggling a few dozen bits in some pages Mar 25 22:04:43 same for eMMC (at least cheaper ones) Mar 25 22:05:47 rcn-ee[m]: might be worth buying an industrial SLC sd card and never have to worry about it again :) Mar 25 22:06:24 might even save money in the long run Mar 25 22:06:32 if you "consume" enough sd cards Mar 25 22:17:00 https://www.digikey.com/products/en/memory-cards-modules/memory-cards/501?FV=238024b%2C238025c%2C238025d%2C2380263%2C238026f%2C2540085%2C254004d%2C8e80019%2C8e8004c%2Cffe001f5&quantity=0&ColumnSort=1000011&page=1&stock=1&pageSize=25 Mar 25 22:18:22 with expected lifetime being two orders of magnitude larger than consumer TLC cards (afaik), they seem downright cheap Mar 25 22:36:17 at my last internship they had a giant box full of about-to-explode LiPos Mar 25 22:37:14 it's a more dangerous collection hobby than µSD Mar 25 22:37:58 you should have connected them in parallel and try to charge the whole array to 5V ;D Mar 25 22:38:06 lol Mar 25 22:40:22 they were leaving the naked wires just like that Mar 25 22:40:39 I guess the probability of a +- +- connection is pretty low, but still Mar 25 22:44:05 what could possibly go wrong Mar 25 23:39:38 insurance scam ? :) **** ENDING LOGGING AT Tue Mar 26 02:59:56 2019
