Ath9k : probe of ar933x_wmac failed with error -22

I installed OpenWrt 19.7.06 on dragino 2 hardware, I am getting this error message in dmesg. Any idea why this error? and How to fix it?

you probably want to post a bigger snippet from dmesg.

Please find the complete dmesg log here --->

[ 25.512997] ath: invalid regulatory domain/country code 0xb5ab
[ 25.513002] ath: Invalid EEPROM contents

have you installed the firmware package ?

Is it the same device as ?

No this is a different device (custom).

How to install firmware package?

opkg update
opkg install >package-name<

I cannot install via opkg. I have to include it while building image.

Any idea which firmware package to include?

no, since you haven't told us anything about your hardware.

lspci and/or lsusb might help though.

U can see the hardware details in screenshot I sent.

Bus 001 Device 002: ID 0424:4504 Standard Microsystems Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

no, you sent the cpuinfo, which is something completely different.

If you want me to send any other hardware info, which I can get via command line in OS. Please let me know. I will share it.

lspci would probably help.
