Jetson Nano 4.6.6 using backport-iwlwifi-dkms

Hi,

I’m trying to get an Intel AX200 card working on my Jetson Nano (JetPack 4.6.6, kernel 4.9.337-tegra). I tried installing iwlwifi either by installing backport-iwlwifi-dkms via APT, or building manually from the core45 branch however, building fails with errors related to macros like BUILD_BUG_ON, BUILD_BUG_ON_ZERO, etc. These are defined in my /usr/src/kernel/kernel-4.9/include/linux/build_bug.h that I installed from nvidia’s public_sources.tbz2 but the build still fails

Has anyone successfully built iwlwifi on this kernel version (4.9.337)?

Do I need to patch backport-iwlwifi manually, or is there a known-good commit that still supports Jetson’s 4.9 kernels?

Thanks in advance.

Hello @utkuoksuz,

Have you tried building Jetpack from source ?

At some point during the build process you should be able to interact with the kernel build menu. Where you could look for IWL Wifi driver options. If none are available, we would suggest finding the kernel version specific to that Jetpack version and checking the git repo for the linux kernel and see if you could add support for the driver on your local clone of Jetpack sources.

We have added support for other wifi cards on kernel 6.12 using the bring your own kernel support from NVIDIA on a custom Yocto build for NVIDIA Jetson NX and we managed to simply enable the kernel drivers through a kernel config file.

Please let us know if you have any further questions, we would love to help.

best regards,

Hi,
You may need to manually enable some configs and rebuild kernel. For kernel customization, please refer to

https://docs.nvidia.com/jetson/archives/l4t-archived/l4t-3276/index.html#page/Tegra%20Linux%20Driver%20Package%20Development%20Guide/kernel_custom.html#

May also consider use Orin series such as Orin Nano. A user has shared his experience in
