Wireless NIC on LS1028ARDB

[Teruharu]

Has anyone used the Intel AX210 wireless NIC with the LS1028ARDB?

After setting the correct kernel parameters, the wireless NIC can be recognized in lspci as "Network controller: Intel Corporation Device 2725 (rev 1a)" but the default kernel source doesn't include the device firmware for the AX210. From Intel's info located here, AX210 needs at least kernel version 5.10+ to work, I used LSDK-2108-RT so my environment can meet this requirement. But the /lib/firmware is not exist, I tried create it manually then copy .ucode file into it or install linux-firmware package by apt but non of them work. Basically after I installed the linux-firmware package, iwlwifi-ty-a0-gf-a0-59.ucode is reachable in /lib/firmware, but error log still have nothing change. Are there any other path stores the .ucode firmware file?

So could anyone tell me how to get the AX210' Wi-Fi function work?

Here are the logs of releated commands

Hi ,

Any solution for above?

I am using imx8 board and android installed. I am also facing same issue.

How I can install iwlwifi-ty-a0-gf-a0-59.ucode as part of kernel image ?

Thanks,
