Step 2:
vim device/fsl/sabresd_6dq/init.rc

＃service p2p_supplicant /system/bin/wpa_supplicant \

　　class main
　　socket wpa_wlan0 dgram 660 wifi wifi
　　disabled
　　oneshot

Step 3：
Decompress "realtek_wifi_SDK_for_android_KK_4.4_20140117.tar.gz” ，then ANDROID_SDK/hardware/realtek in it will be covered to hardwar/realtek directory of android source code.

Step 4：
vim hardware/libhardware_legacy/wifi/Android.mk

＃ifeq ($(BOARD_WLAN_DEVICE),UNITE)
＃ LOCAL_C_INCLUDES += $(LOCAL_PATH)/../../external/wpa_supplicant_ath/wpa_supplicant/src/common
＃ LOCAL_SRC_FILES += wifi/wifi_unite.c
＃else ifeq ($(BOARD_WLAN_VENDOR), INTEL)
＃ LOCAL_SRC_FILES += wifi/wifi_intel.c
＃ LOCAL_C_INCLUDES += $(LOCAL_PATH)/../../external/wpa_supplicant_8/src/common
＃else
＃ LOCAL_SRC_FILES += wifi/wifi.c
＃ LOCAL_C_INCLUDES += $(LOCAL_PATH)/../../external/wpa_supplicant_8/src/common
＃endif

ifeq ($(BOARD_WIFI_VENDOR),realtek)
LOCAL_SRC_FILES +=../realtek/wlan/libhardware_legacy/wifi/wifi_realtek.c
else
LOCAL_SRC_FILES += wifi/wifi.c
endif

Step 5：
Backup "wpa_supplicant_8" under "external/"of "android" souce code，then decompress "wpa_supplicant_8_kk_4.4_rtw_r10450.20140220.tar.gz" in the driving package and rename as "wpa_supplicant_8" and replaced to "external/" directory of "android" 。</span>

Step 6：
Modify "kernel_imx/arch/arm/configs/imx6_android_defconfig",(or modify ".config") configure the following items as "Y"
CONFIG_CFG80211=y

CONFIG_MAC80211_MESH=y

CONFIG_MAC80211=y

CONFIG_HOSTAP=y

CONFIG_USB_USBNET=y

Step 7:

vim device/fsl/imx6/etc/init.rc

　setprop wifi.interface wlan0
　setprop wlan.driver.status "ok"


Step 8:
Delete system folder in "out/target/product/sabresd_6dq" and folder of "wpa_supplicant_intermediates" in "out/target/product/sabresd_6d/obj/EXECUTABLES"，re-compile "system.img" and" boot.img".

Step 9：
Compile "wlan.ko" and copy to directory of “system to /lib/modules/ ”

vim Makefile
CONFIG_PLATFORM_I386_PC = n

CONFIG_PLATFORM_NEW = y

ifeq ($(CONFIG_PLATFORM_NEW), y)
EXTRA_CFLAGS += -DCONFIG_LITTLE_ENDIAN
ARCH := arm
CROSS_COMPILE :=/home/linyn/android/android-myzr/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin/arm-eabi- KSRC := /home/linyn/android/android-myzr/kernel_imx
MODULE_NAME := wlan
endif

vim include/autoconf.h

＃define CONFIG_IOCTL_CFG80211
＃ifdef CONFIG_IOCTL_CFG80211
＃define RTW_USE_CFG80211_STA_EVENT

//＃defineCONFIG_CFG80211_FORCE_COMPATIBLE_2_6_37_UNDER

//＃define CONFIG_DEBUG_CFG80211 1
＃endif
...
...
＃define CONFIG_CONCURRENT_MODE

＃define CONFIG_P2P_IPS
Finally compiled to wlan.ko and copy to directory of system/lib/modules/

Port 3G（MU609）

Step 1：
 vim kernel_imx/drivers/usb/serial/option.c

＃define HUAWEI_PRODUCT_E353:　　 0x1506
instead
＃define HUAWEI_PRODUCT_E353:　　 0x1573

Step 2：
 vim hardware/ril/rild/rild.c

＃define REFERENCE_RIL_DEF_PATH "/system/lib/libreference-ril.so"
instead
＃define REFERENCE_RIL_DEF_PATH "/system/lib/libhuawei-ril.so"

...
// switchUser();

Step 3：
 Vim hardware/ril/runtime-ril-port/runtime_port.c

Add new structure in arrays
static struct modem_3g_device modem_3g_device_table[] = {

   {
　　.name:　　= "Huawei-MU609",
　　.idVendor = "12d1",
　　.idProduct = "1573",
　　.deviceport = "/dev/ttyUSB2",
　　.dataport = "/dev/ttyUSB0",
　　.type:　　= HUAWEI_MODEM,
   },


Step 4：
 Copy ip-up,ip-down to directory of /system/etc/ppp,copy libhuawei-ril.so to directory of /system/lib.

Step 5:
 vim device/fsl/imx6/etc/init.rc

Modify with following reference:
chmod 777 /dev/ttyUSB0
chmod 777 /dev/ttyUSB2
chmod 777 /etc/ppp/ip-up
chmod 777 /etc/ppp/ip-down
＃service ril-daemon /system/bin/rild
service ril-daemon /system/bin/rild -l /system/lib/libhuawei-ril.so

Step 6:
 Re-compile system.img and boot.img
