Hi, I want to only update kernel and modules, I use this way:
1. modify /boot/extlinux/extlinux.conf to backup kernel
2. copy new kernel to board
3. strip and tar modules,then copy to board
4. update lib/modules/<version> with step3
then, jetson boot up and everything is ok , except no UI. Are there some error to update kernel and modules?
Note: I know there is a flash.sh script that’s provided by nvidia. But it’s too violent, because I just wanted to update the kernel and modules.
Hi,
so are still able to login via UART?
Can you run
sudo depmod -a
and reboot to see if it helps?
yes,can login via UART
I run sudo depmod -a and reboot, but no effect.
Hi,
what modification did you make to the kernel image?
Will it work fine if you do a complete re-flash?
Also, what device are you using? The title says Jetson Orin (AGX, NX, Nano?), but you posted in the Jetson Nano section.
what modification did you make to the kernel image?
I want to disable IOMMU,
Will it work fine if you do a complete re-flash?
No，it’s no work. I test just now. I replace those files followed build kernel, but when device boot up there are too many those messages:

Hi,
will runningexport LOCALVERSION="-tegra" before compiling the kernel make any change?
Also, I’m not sure if it’s required, but you may also need to compile the display driver:
https://docs.nvidia.com/jetson/archives/r35.3.1/DeveloperGuide/text/SD/Kernel/KernelCustomization.html
will running
export LOCALVERSION="-tegra"before compiling the kernel make any change?
I use nvbuild.sh script to compile kernel ,so it’s with export LOCALVERSION="-tegra" by default.
Also, I’m not sure if it’s required, but you may also need to compile the display driver:
OK,I will try it.thank you!
