Jetpack5.0.2 kernel compile error

drivers/video/Kconfig:27: can’t open file “drivers/video/tegra/Kconfig”

Did you follow the document to compile the kernel?

https://docs.nvidia.com/jetson/archives/r35.1/DeveloperGuide/text/SD/Kernel/KernelCustomization.html

Hello,
I am facing a similar issue in compiling kernel with my own set of commands:

I populated the sources with the below command:
./source_sync.sh -k jetson_35.1

Compiling:

$ make ARCH=arm64 CROSS_COMPILE=<toolchain>/bin/aarch64-buildroot-linux-gnu- -C sources/kernel/kernel-5.10/ -o $PWD/kernel_out/ tegra_defconfig
make: Entering directory '<PATH>/Linux_for_Tegra/sources/kernel/kernel-5.10'

drivers/video/Kconfig:27: can't open file "drivers/video/tegra/Kconfig"
make[1]: *** [scripts/kconfig/Makefile:89: tegra_defconfig] Error 1
make: *** [Makefile:633: tegra_defconfig] Error 2
make: Leaving directory '<PATH>/Linux_for_Tegra/sources/kernel/kernel-5.10'

The problem comes from:

$ grep -rn “drivers/video/tegra/Kconfig” sources/kernel/
sources/kernel/kernel-5.10/drivers/video/Kconfig:27:source “drivers/video/tegra/Kconfig”

But there is no directory named ‘tegra’
$ ls -l sources/kernel/kernel-5.10/drivers/video/tegra
ls: cannot access ‘sources/kernel/kernel-5.10/drivers/video/tegra’: No such file or directory

Please follow the document to compile the kernel. I just verify without problem.

Thanks

We are encountering a similar issue. It seems what is being pulled by source_sync.sh is missing the aforementioned files. They are however included in the public_sources.tbz2 kernel sources (kernel_src.tbz2 archive). Manually copying the contents of kernel/nvidia/ to the matching directory pulled by source_sync.sh is our workaround.

Upon looking into it further, this just seems to be an issue with the ordering of SOURCE_INFO elements in source_sync.sh.

Specifically, since nv-tegra.nvidia.com/kernel/nvethernetrm.git is cloned prior to nv-tegra.nvidia.com/linux-nvidia.git, git obviously refuses to clone linux-nvidia into a non-empty directory. The easiest solution is to just patch source_sync.sh such that linux-nvidia.git is cloned prior to the other repositories that will be entailed within it:

Alternatively, cd into nvidia directory, then:

git init
git remote add origin git://nv-tegra.nvidia.com/linux-nvidia.git
git fetch --depth=1 origin jetson_35.1
git checkout FETCH_HEAD

Have a try this file to sync the source or download the public.tbz2 from download center.

source_sync.sh (11.0 KB)
nvbuild.sh (3.7 KB)
