    bring up brcmfmac 43455 on freescale vybridvf6xx

    AdCo_2492116

      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.
