I just operated the scripts as you described, but still display “Unknown symbol xxx”, I noticed this post which is a similar problem on Thor:
[JetPack 7.1 R38.4] nvidia-display-install questions - Jetson Systems / Jetson Thor - NVIDIA Developer Forums
Nvidia official adivice is to copy the .ko files from “rootfs/lib/modules/6.8.12-tegra/updates/opensrc-disp” directory to the “rootfs/lib/modules/6.8.12-tegra/updates/opensource-gpu-disp”， and the OS successfully started after I tried it.
What puzzled me is why there are three .ko files locations(size are different from each other):
$ sudo find . -name nvidia.ko -ls

and why executing sudo ./apply_binaries.sh --openrm to obtain four inaccurate ko files?
