    LM832 CYW43438 driver error


      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?
