Thank you very much for your work and information.
As I understand it is only an issue of kernel 6.1, so nothing to do with 5.15 kernels?
Best Regards,
Eh, This only affects BBBs or is my BVF going away to the graveyard in weeks also?
What about all the derivatives, like BBG(W), Blue and friends?
one more question:
How-to install different kernel without access to internet?
I am able to ssh to the BBB and upload files with scp. But the BBB has no direct access to internet for using apt install e.g.
sudo apt update
sudo apt install bbb.io-kernel-5.10-ti-am335x

Youâre doing product development wrong. Connect the board to the Internet, install what you need, test, repeat. Then remove it from the Internet.
⌠and a big sigh of relief was heard across the land âŚ
Mine has a Micron device of some description.
Hi Robert,
in january I decided to go with kernel 6.1 and debian 12. Unfortunately I have not seen the discussion around problems with emmc. During my tests everything worked fine. I have no active writing activities to the emmc, so problems seem to arise later.
Only the debian internal system seems to write some changes. On previous versions I never had an issue with the emmc.
After some month I observed after a powercycle the BBB wonât start again.
For some BBBs (approx 600 km away from home ;-( ) without direct internet connection my wish was to prepare a tgz file or s.th. equivalent and bring it via scp to that BBB and switch to a 5.10 kernel to avoid crashing the emmcâs.
Here at home I just tried copying all kernel specific files in /boot/ to a target BBB and changed the âuname=âŚâ in /boot/uEnv.txt and rebooted. Seemed to work.
But I am not sure if other problems will come up.
Which would be the best way, if no help is available at the other location?
Thank You again!
Best Regards,
All of our serious work is air gapped from the âpublic internetâ. Targets live on their âmockâ internet environment. You need a metal box with dual internet ports and a server on the air-gap side. You can use apt and dpkg commands as well as git mirror to set every thing up. When they go on public internet for live testing the targets are under a microscope.
Typically we now use yocto builds so its already installed and configured. This all depends on the many issues and project requirements.
Just grab the matching linux-image-(version).deb you need, then upload it and install via dpkg on your external device. https://rcn-ee.net/repos/debian/pool/main/l/linux-upstream/
Thank you! Great answer!
Thatâs what I needed,

Whatâs nice, that board that did fail, had a phy bug, so i was able to verify a new board with new gpio reset, and that the updated gpio reset fixed it⌠So add it my ci, as a phy testerâŚ

Youâre going through an awful lot of BBBâs, arenât you?
and another just bit the dust!
eMMC life_time: 0x02 0x01
eMMC serial: 0x59923d72
I donât know what scares me more,
You, still searching for the right combination of quirks,
or the fact that you still havenât run out of BBBs to test destructively. 
I hope youâre getting sponsored or at least youâre able to rework
new eMMCs onto those BBBs.
