Orin NX reboot force update from L4T 4.0 (Jetpack 6.1) to L4t 4.3 (Jetpack 6.2)

[thibault.vernay]

Hi there ! Thanks for all answers on other post, but I wasn’t able to find a solution to my problem, let me exposed it there :

We have flashed my Jetson ORIN NX module with Jetpack 6.1 (L4T R36 rev 4.0), and then install some packages with apt and download my source code with git. Everythings work fine.

Then, we do reboot my board, at startup we get this screen :

After boot I can see that L4T version has changed :

This is a pain as we work on custom devboard, with custom DTB and Image to support our camera driver, and this update seems to update tegracam_v4l2subdev API as we got the following errors :

Is there a way to prevent L4T from updatating to R36 rev 4.3 as R36 rev 4.0 feats our needs ?

I’ve apt-marked thoose packages but it don’t change anything :

I would like to ass that we previouly worked on Xavier NX with Jetpack 5.1.1 (L4T R35 rev 3.1) and we had never seen such behaviour.

Thanks again for all your answers ! I hope you’ll help me to solve this new problem !

Hi,

What commands trigger the force update?
Could you provide the commands you execute?

Do you hold nvidia-l4t-display-kernel before do sudo apt update && apt upgrade

sudo apt-mark hold nvidia-l4t-display-kernel nvidia-l4t-kernel nvidia-l4t-kernel-dtbs nvidia-l4t-kernel-headers nvidia-l4t-kernel-oot-headers nvidia-l4t-kernel-oot-module

Please refer to related topic [Jetpack 6.1/r36.4.0] Self-built kernel is overwritten after sudo apt update && sudo apt upgrade in

Hi David !

Thanks for your quick answer and the link !

What commands trigger the force update?
Could you provide the commands you execute?

I just run generic apt install command for gstreamer, tensorrt, ...

I didn’t hold nvidia-l4t-display-kernel indeed, marking it solved the problem !

Thanks a lot for your help !
