Hi, I'm trying to use the CYW43455 for Wifi on release 2.3.4 of Android. I have Wifi running on Linux on this board, so I know it's not a hardware problem.
I get this in the kernel.
[ 3.354573] brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac43455-sdio for chip BCM4345/6
[ 3.363535] brcmfmac mmc1:0001:1: Direct firmware load for brcm/brcmfmac43455-sdio.bin failed with error -2

So the driver appears to be loading, and I get wlan0 when I run "ifconfig -a", however running "ifconfig wlan0 up" causes
ifconfig: ioctl 8914: Unknown error 132
When I run
/vendor/bin/hw/wpa_supplicant -O/data/vendor/wifi/wpa/sockets -puse_p2p_group_interface=1 -g@android:wlan0
I get
01-06 00:31:48.576 3595 3595 D wpa_supplicant: wpa_supplicant v2.7-devel-9
01-06 00:31:48.578 3595 3595 D wpa_supplicant: Global control interface '@android:wlan0'
01-06 00:31:48.578 3595 3595 E wpa_supplicant: Failed to open Android control socket 'wlan0'
01-06 00:31:48.578 3595 3595 E wpa_supplicant: Failed to initialize wpa_supplicant
What am I doing wrong? What else do I need to set up to make it work?
