3.8.13 - Cannot flash Beaglebone Black

General Discussion
1

Hello, Many years ago, we have created our own flaser image for the Beaglebone Black. When the engineer is going to program it in the factory we never have a problem, until a few weeks ago. Now I have four Beaglebones on my desk witch I cannot program. Of course, I push the user button when power up and I tried different CD cards to be sure the SD card is not broken. After a few seconds, the Beaglebone stops responding (terminal freezes) and user LED D4 burns, the rest is off (except power LED D1).
Here is the debug log of a (non working) Beaglebone.

Welcome to The Ångström Distribution v2012.12!

If you compare them, you will notice a difference between those two. On a working Beaglebone, the following lines occur in the log:

[ 1.861924] mmc0: host does not support reading read-only switch. assuming write-enable.
[ 1.879761] mmc0: new high speed SDHC card at address 1234
[ 1.899735] mmcblk0: mmc0:1234 SA04G 3.63 GiB
[ 1.908088] mmcblk0: p1 p2

From this, I conclude, the non working Beaglebone doesn’t see the SD card properly, resuling in this log line:

[ 2.348885] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(179,2)

If I jump into the UBOOT cli, (by removing the SD card on time) and comparing the printenv list, I am not seeing any differences (excep MAC address)

I also tried an official Beaglebone black image. On a working Beaglebone, there is no problem programming it. On a non working Beaglebone, the same problem occurs with our own image.
I also checked the hardware on missing resistors and checking their values. I didn’t find any difference with a working Beaglebone.
Should I send them RMA, or does anyone have an idea? Please advice.

Best Regards,
Kees

I see in your logs that failed BBB was unable to initialize mmc0 card at all, and eventually did panic and die.
compare this lines:
Working BBB have following:

also don’t confuse yourself with mmcblk0
on working BBB mmcblk0 is represented by mmc0:1234 SA04G 3.63 GiB
on non working BBB mmcblk0 is represented by mmc1:0001 MK2704 3.53 GiB**

Why you can’t boot from uSD card at all (probably): Your kernel is trying to load filesystem from /dev/mmcblk0p2
When mmc0 is fine - that device represent partition #2 of uSD card and it’s known to kernel
when mmc0 is missing /dev/mmcblk0p2 is representing your mmc1, partition #2 - which don’t exist at all.

Both BBB boards have same hardware revision?
Did you compare uSD connectors and their revisions ?
If i remember correctly BBB RevC3 did some changes related to mmc0 

If they are different maybe it did change some pins and you need to change device-tree.

3

Only GND pins and EMI fixes
 hardware wise shouldn’t stop the old 3.8.13 based kernel from booting.

Both mmc1:0001 MK2704 3.53 GiB in those logs is the eMMC


So what’s randomly not showing up is the microSD


But it’s 3.8.13.

Regards,

4

Yea, i did understand that eventually and already fixed my statements.
Thanks.

5

it’s part of the fun of 3.8.13
 as long as everything works, it works
 but in the sdhci driver, it’s a big race between microSD/eMMC to who loads first to get /dev/mmcblk0. :wink:

6

I believe we are encountering a similar issue with version 3.8.13. The SD card does not show up. We attempted to address the mentioned racing condition by strapping the eMMC to reset, but unfortunately, we were unsuccessful.

7

Thanks for all replies

They have the same hardware revision but the production date is different. All ‘Wrong’ BBB’s starting with BBBCV202308. But there are BBB’s with same leading number that do working fine.

I did compare both uSD connectors and they look the same. Also checked with an Ohm meter the resistance of the uSD card pins to the rest of the board and no differences detected.

But I honestly think, the uSD holder is fine because without uSD card, the BBB is as dead as it could be when I power it up and pressing the S2 button. Also when I only remove the MLO from the boot partition and power the BBB up with the S2 button pressed, the BBB does nothing. But for some reason, the other partitions are not showing up.

Yes, the kernel version is very (very) old. But when I’m using this image on a good BBB, it will flash its EMMC. On a non-working BBB, nothing happens. It seems the BBB just normally starts up from its factory EMMC. (Sorry, in my first post, its not written not correcly). See the startup log:

First of all you didn’t specify from which BBB last log was, it’s from nonWorking ?

I still think issue is related to uSD - but we can investigate further.

Next, boot - up sequences is not a simple stuff
, there are 3 different stages on which system (BBB) can decide change it’s route based on environment which it detects, additionally as @RobertCNelson mention 3.8.13 have it’s own quirks.

To get further we need to establish a base line, so please config each from following statements so I did understand everything right:

  1. After you give power to NonWorking BBB without uSD card - it’s not loading, you don’t see anything in console (including SPL U-boot is missing)
  2. After you give power to NonWorking BBB with uSD - 3.1.8 image - it’s not loading, you don’t see anything in console (including SPL U-boot is missing)
  3. After you give power to NonWorking BBB with uSD - 3.1.8 image and was holding user button - you see SPL U-Boot and Kernel try to load but in end it will die.
  4. After you give power to NonWorking BBB with uSD - Debian 10 image and was holding user button - you see SPL U-Boot and Kernel is loading and you get Login prompt.
  5. If you use Working BBB and do same tests 1-4 - System (BBB) is always booted to Login prompt.

Additionally you can collect additional information from NonWorking BBB,
use 3.8.13 image and start booting, but interrupt U-Boot, then execute following commands in u-boot environment and collect output. Also if you wish you can compare it with working BBB.

env print -a
mmc rescan
mmc list

I did look at your case - yes, it look like same issue.
mmc0 is missing, kernel don’t see mmc0 and mapping /dev/mmcblk0 to mmc1
then trying to load filesystem from /dev/mmcblk0p2 - but internal mmc (mmc1) don’t have “p2” partition at all and kernel die.

As I understand In general that uSD image by design is not good,
it’s correct if you are loading from internal emmc, but it’s wrong for uSD
because if mmc0 is there and allive, then kernel will load filesystem from internal emmc:p2 but should use uSD:p2, if emmc:p2 is missing because of some reasons - uSD will fail to load.
Also most probably if emmc:p2 is there but contain unknown partition table for Kernel 3.8.13 - it will also fail

So back in the 3.8.13 era we did uuid magic to pass the specific microSD/eMMC partition table we wanted to mount
 This also requires a initrd


On mainline, a solution for this problem was finally committed around 5.5.x time frame
 So for many years we lived with uuid/initrd names


But even with the uuid helpers, if the microSD fails to even load, it’ll fail

If it’s just an race issue then most probably they can workaround it.
If emmc will have that old image with all required partition - it should work fine without uSD Card.

I would suggest just to boot in Debian 10 (or other working uSD image), get shell and manually push required images to emmc and that’s all.
If they will want to upgrade it in future to post 5.5 - it would work without issues.
@RobertCNelson do you agree with this approach ?

As your goal is just to update the eMMC, you can really boot any microSD image and then dd your golden eMMC image


BTW, it might be easier to boot and recover a working eMMC image this way


Also depending on u-boot version, you can actually mount the eMMC as a usb-flash device and access the eMMC directly over usb.

Sorry it’s been awhile since i’ve done that


But boot into u-boot, and run something like

mmcdev 0
ums 0 mmc 0

That’s what i did .
I boot into u-boot and deployed the image with ums and now it’s fine . Currently i am looking for an automated way to deploy since doing this for 15 devices(this time) is not very viable .Thanks for the support

14

Update:

Both options worked for me:
Option 1:
mount the emmc from uboot with ums and copy the image to the emmc.
(ums 0 mmc 1)

Option 2:
I used a new kernel in order to boot from the sd card.I had a copy of the old image on the sd card as .img and I pushed my old image to the emmc with dd.

Thanx all for your replies and thoughts.

With using ums commands I could update the BBB with an official image. Now I have to figure out how to use our own custom image.

Thanks again and have a nice weekend!

Did you find any solution? As i mentioned before both methods worked for me but now i released that even though my image working fine from eMMC i can no longer see the SD-CARD in order to use it as an external storage drive .

17

Can you elaborate how exactly it can be done. What I understand is something like this: first, boot up with the latest image from SD, then
“sudo dd if=./bone-debian-7.9-lxde-4gb-armhf-2015-11-12-4gb.img of=/dev/mmcblk0 count=1 seek=1 bs=3481600k”. Regards.

Exactly! that’s what the original Angstrom flasher did!

For faster, take a look at using bmaptool
