Armbian does not support A2 WIFI module

I am trying to make it work with armbian desktop. The device works fine with radxa debian, ubuntu, android.

lshw -short shows (I dont have eMMC attached, booting from microsd)

another similar device that booted into ubuntu shows this ( no 9 is wireless here)

–edit–

the entry for the wireless device was the /b/1/3 mmc2:0001:3 communication 43455
the build was missing module in modules/net/wireless/broadcom

Here is kernel config:


In case some firmware is missing:

I see broadcom wireless is not added in the config, and the resulting setup does not contain brcmfmac.ko module.

CONFIG_BRCMFMAC is not set

Currently trying to build by adding that option.

I used armbians build mechanism
Selected option to customize config
Searched for CONFIG_BRCMFMAC and enabled it
It worked
I believe it should be added for the defaultmbuild
