I am trying to attach LM832 to my raspberry pi compute module. However i am not able to attach or find it. I think it will not require external drivers.

I am able to detect mmc1 as module. But on driver load I get

$ sudo modprobe brcmfmac

$ sudo dmesg -c

What can be cause of such problem?

Hi AkBh_4566821

Could you check whether you have a  clm_blob in the directory where you have kept the firmware for the wlan chip.

Does ifconfig display a wireless interface?
