Hi,

we have a custom embedded system based on freescale vybrid vf6xx SOC.

-run kernel 4.3.0

-looking to replace wifi chip with murata mw1, that uses cypress 43355 chip.

-bt part is working fine.

-updated/patched the "/drivers/net/wireless/brcm80211/brcmfmac" driver to:

     -download fw and related files.

     -create wlan0 interface. OK

          root@E8c08d60d461f7:/root $ ifconfig wlan0

          wlan0     Link encap:Ethernet  HWaddr E8:E8:B7:0D:7B:9A 

          BROADCAST MULTICAST  MTU:1500  Metric:1

          RX packets:0 errors:0 dropped:0 overruns:0 frame:0

          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

          collisions:0 txqueuelen:1000

          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

-trying to bring up the interface wlan0 will fail:

     -brcmf_netdev_open() fails when calls

          > brcmf_config_dongle()

               >brcmf_fil_cmd_int_set

                  >brcmf_fil_cmd_data error TIMEOUT(-110)

Any help on this issue will be greatly appreciated.

Hi

Could you provide the version of fmac that is being used here?

Please make sure that you are loading the firmware from the appropriate location that the driver checks.

Could you confirm that the steps that you follow align with instructions given in the README attached.
