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

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?
