drivers/video/tegra/Kconfig does not exist & can't be created

Jetson AGX Orin Dev Kit 64g
Ubuntu 20.04.6 LTS ~ 64-bit
GNOME Version 3.36.8
Jetpack 5.1.2

I’m relatively new to Linux so I’m sure I’m overlooking something simple (and probably didn’t even post enough background info^), but I’m attempting to run a make file to create then install a module and I keep receiving the error:

make     -C /lib/modules/5.10.120-tegra/build     SUBDIRS= modules
make[1]: Entering directory '/usr/src/linux-headers-5.10.120-tegra-ubuntu20.04_aarch64/kernel-5.10'
  SYNC    include/config/auto.conf.cmd
drivers/video/Kconfig:27: can't open file "drivers/video/tegra/Kconfig"
make[3]: *** [scripts/kconfig/Makefile:71: syncconfig] Error 1

make[1]: Leaving directory '/usr/src/linux-headers-5.10.120-tegra-ubuntu20.04_aarch64/kernel-5.10'
make: *** [Makefile:6: default] Error 2

I’ve tried the solution(s) posted on the forum(s), including the .source_sync.sh && nvbuild.sh post/topic, but to no avail. I’ve worked on this for two days trying everything and I’m finally pressing the help button - if anyone has any insight and/or solutions, I would be greatly appreciative, or if anyone who is more experienced in Linux than me can hold my hand (so to speak) and help me troubleshoot, I’d also be very grateful. I’ve pretty much reached a dead-end and don’t know how to proceed.

Thank you any and everyone for reading this and for any time/help/support you’re able to offer. Looking forward to hopefully hearing back from someone.

Hi,

What if you just copy the file from /kernel/nvidia/drivers/ to /kernel/kernel-5.10/drivers?

Jetpack5.0.2 kernel compile error

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.

Or manually make the config file again:

Make menuconfig

Same boat. Here is a suggestion: Tested and it works (Jetpack 5.1.1) Not sure if it helps in your case. It works for me. Feedback welcome. make -C kernel/kernel-5.10/ ARCH=arm64 mrproper (to start from a clean config) make -C kernel/kernel-5.10/ ARCH=arm64 O=$PWD/kernel_out tegra_defconfig make -C kernel/kernel-5.10/ ARCH=arm64 O=$PWD/kernel_out menuconfig if you compile with ./nvbuild.sh, it will overwrite again the .config on the kernel_out folder.

None of those options ended up working/solving the issue - We appreciate you looking into this for us, though.

We were eventually able to get the module integrated, however. If anyone runs into issues using a Waveshare USB LTE module (ours is the SIM7600G-H 4G Dongle) on the Jetson AGX Orin, we were able to get it integrated by typing the following command into minicom:

AT+CUSBIDSWITCH=9011.1.1

No waveshare or simwwan drivers were needed.
