Debian 11 supported kernel versions

[me21]

Hello everyone,

I know Debian 11 images are running kernel v5.10.x-ti by default, would it be possible to replace it with v4.19.x-ti? I currently have some PRU interaction in the software, don’t want to break something by upgrading Linux kernel.
I can build the image myself, I just want to know if there’s any known incompatibility, things to consider, etc.

Hi @me21 this is no issue… Using…

[ARMHF] Debian 10.x/11.x/12.x Kernel Updates

I’m looking to end the “update_kernel.sh” script, in Debian 10.x/11.x i’m working meta packages for kernel branches for users to more easily stay on a LTS kernel: Example For example, to stay on v5.10.x-ti for the am335x just run: sudo apt update sudo apt install bbb.io-kernel-5.10-ti-am335x sudo reboot Upgrades: sudo apt update ; sudo apt upgrade All Options (only install one, if you install 2, your upgrades will swap between…) *-ti branches: These follow, TI’s lts branch for as long as…

Just run:

Disable auto kernel updates from 5.10.x-ti branch

sudo apt remove bbb.io-kernel-5.10-ti-am335x

Install and enable auto kernel updates from 4.19.x-ti branch

sudo apt install bbb.io-kernel-4.19-ti-am335x
sudo reboot

and you’ll be all set…

4.19.x-ti is the ‘oldest’ that gets active testing by me…

If you’re looking to enable PRU uio under the newer kernels, I’ve had great luck using this overlay:

https://github.com/mvduin/overlay-utils/blob/master/uio-pruss-5.4.dtsi

I was able to continue using my older PRU code with this overlay, and I’ve found the newer kernels to be much more stable.
