Hi everyone,
I am working on a Yocto build for my device and need to ensure compatibility with the Intel AX210 Wi-Fi module. Specifically, I am trying to determine which drivers or firmware files I need to include in the /firmware folder of my Linux image.
I understand that the required firmware files might be available in the Linux firmware Git tree:
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/
However, since the repository contains a wide range of middleware, I want to avoid adding unnecessary files to prevent overloading the image or wasting space.
Could anyone guide me on which specific files are required for the AX210 module? Any pointers or advice on creating a custom Yocto recipe to include only the necessary firmware would be greatly appreciated.
Thank you in advance!

I conducted a brief research and found instructions on the Linux wireless documentation page:
https://wireless.docs.kernel.org/en/latest/en/users/drivers/iwlwifi.html
The page clearly states the following:
If you do get it from linux-firmware.git, you’ll have to copy the files to the appropriate location on your system. Where that appropriate location is depends (again) on your system distribution. You can typically find this location by looking in the udev scripts of your distro, the default on most distributions is /lib/firmware.
Installation of the firmware is simply:
# cp iwlwifi-*.{ucode,pnvm} /lib/firmware/
You can now load the driver.
I hope this topic will reduce the research time for newcomers and help them locate the appropriate files for their Wi-Fi modules.
