The default wifi driver of the system is ar6000, but I want to use the 8686 device. How to configure the system? I have configured the kernel and the kernel can load 8686 drive corretly. I also modified the Boardconfig.mk , init.rc ,wifi.c  In device/fsl/imx53_logo/Boardconfig.mk:  #WIFI_DRIVER_MODULE_NAME := "ar6000" #WPA_SUPPLICANT_VERSION := VER_0_6_ATHEROS WPA_SUPPLICANT_VERSION := VER_0_6_X #BOARD_WLAN_ATHEROS_SDK := system/wlan/atheros/AR6kSDK #BOARD_WPA_SUPPLICANT_DRIVER := AR6000 BOARD_WLAN_CHIP_AR6102 := true BOARD_WLAN_CHIP_AR6003 := true BOARD_WPA_SUPPLICANT_DRIVER := WEXT # Select Wake on wireless mode for AR6003 suspend/resume policy BOARD_WLAN_PM_SUSPEND := 2  In the device/fsl/imx53_logo/Init.rc, I commented out the sentences.  #service wpa_supplicant /system/bin/wlan_tool wpa_supplicant # socket wpa_wlan0 dgram 660 root wifi # disabled # oneshot  #service wlan_tool /system/bin/wlan_tool # oneshot  In the device/fsl/imx5x/init.rc, I modified some places.  # give system access to wpa_supplicant.conf for backup and restore mkdir /system/etc/wifi 0770 wifi wifi chmod 0770 /system/etc/wifi chmod 0660 /system/etc/wifi/wpa_supplicant.conf chown wifi wifi /system/etc/wifi/wpa_supplicant.conf  #wpa_supplicant control socket for android wifi.c (android private socket) mkdir /data/misc/wifi 0770 wifi wifi mkdir /data/misc/wifi/sockets 0770 wifi wifi chmod 0770 /data/misc/wifi chmod 0660 /data/misc/wifi/wpa_supplicant.conf chown wifi wifi /data/misc/wifi chown wifi wifi /data/misc/wifi/wpa_supplicant.conf  service wpa_supplicant /system/bin/wpa_supplicant -dd -Dwext -iwlan0 -c /system/etc/wifi/wpa_supplicant.conf socket wpa_wlan0 dgram 660 wifi wifi group system wifi inet disabled oneshot  In the hardware\libhardware_legacy\wifi\wifi.c, I modified some places.  #else /* ATHENV */  #ifndef WIFI_DRIVER_MODULE_PATH #define WIFI_DRIVER_MODULE_PATH "/system/lib/modules/libertas_sdio.ko" #endif #ifndef WIFI_DRIVER_MODULE_NAME #define WIFI_DRIVER_MODULE_NAME "libertas_sdio" #endif #ifndef WIFI_DRIVER_MODULE_ARG #define WIFI_DRIVER_MODULE_ARG "" #endif #ifndef WIFI_FIRMWARE_LOADER #define WIFI_FIRMWARE_LOADER "" #endif #define WIFI_TEST_INTERFACE "wlan0"  #endif  In the external\wpa_supplicant_6\wpa_supplicant\wpa_supplicant.conf, I modified some place.  ctrl_interface=wlan0  I think the system use the Android private socket, but I am not sure.  After I run the system, the error come out. I have attached the log file. Thanks!
