Hello guys,
I’m trying to write device driver for PAL/MIPI and i stucked on problem with device tree. I’m using Linux version 36.2 and AGX ORIN dev kit. My device tree:

When i try to compile new dtb via nvbuild.sh new dt seems like unconfigured, As far as I checked different posts this is most common and confirmed method.
Kind regards
