No display after custom kernel compile

[younes.khadraoui]

Hello;

I compiled a custom kernel following the official tutorial. I replaced /boot/Image with the generated one, and the entire folder /lib/modules/5.10.104-tegra/ with the generated one …/modules_out/lib/modules/5.10.104-tegra/

All is working good, I compiled additional modules and they well loaded and working. The only thing that is not working is the display.

There is an error in dmesg:

[    0.618540] tegradccommon module_init failed
[    0.622810] tegradc module_init failed

From what I understood reading other threads, it’s actually related to the display.

Am I missing a step here ?

p.s. I always set LOCAL_VERSION to -tegra, I guess that’s not an errror related to that, as the kernel is actually able to load all other modules.

Thank you

Are you asking this on Xavier or Orin…?

Because tegradc driver is not in use on Orin. Thus, if this is on Orin, then you don’t need to care about that error log.

I solved the issue by loading manually nvidia driver :

sudo modprobe nvidia

Thank you
