[meta-freescale] Problem with wifi configuration RTL8723BS on IMX6 SabreSD Android

[Anderson Mark]

Hello All!

Have i.MX 6Quad Freescale SabreSD with Android 4.3

https://community.nxp.com/message/903570


I want to connect to SabreSD the wifi module RTL8723BS by SDIO.

The main problem is:

I configure everything according to the instructions, but unfortunately it is not going to build like a KO (module).


Step by step:

  1.  vim kernel_imx/arch/arm/configs/imx6s_{yourdevice}_android_defconfig



CONFIG_CFG80211=y
CONFIG_MAC80211_MESH=y
CONFIG_MAC80211=y
CONFIG_HOSTAP=y
CONFIG_RTL8723BS=m



2. vim device/fsl/{yourdevice}/BoardConfig.mk



BOARD_WIFI_VENDOR := realtek
ifeq ($(BOARD_WIFI_VENDOR), realtek)
    WPA_SUPPLICANT_VERSION := VER_0_8_X
    BOARD_WPA_SUPPLICANT_DRIVER := NL80211
    CONFIG_DRIVER_WEXT :=y
    BOARD_WPA_SUPPLICANT_PRIVATE_LIB := lib_driver_cmd_rtl
    BOARD_HOSTAPD_DRIVER        := NL80211
    BOARD_HOSTAPD_PRIVATE_LIB   := lib_driver_cmd_rtl

    BOARD_WLAN_DEVICE := rtl8723bs
    #BOARD_WLAN_DEVICE := rtl8192du
    #BOARD_WLAN_DEVICE := rtl8192ce
    #BOARD_WLAN_DEVICE := rtl8192de
    #BOARD_WLAN_DEVICE := rtl8723as
    #BOARD_WLAN_DEVICE := rtl8723au
    #BOARD_WLAN_DEVICE := rtl8189es
    #BOARD_WLAN_DEVICE := rtl8192cu
    #BOARD_WLAN_DEVICE := rtl8723bu

    WIFI_DRIVER_MODULE_NAME   := "wlan"
    WIFI_DRIVER_MODULE_PATH   := "/system/lib/modules/wlan.ko"
    WIFI_DRIVER_MODULE_ARG    := "ifname=wlan0 if2name=p2p0"

    WIFI_FIRMWARE_LOADER      := ""
    WIFI_DRIVER_FW_PATH_STA   := ""
    WIFI_DRIVER_FW_PATH_AP    := ""
    WIFI_DRIVER_FW_PATH_P2P   := ""
    WIFI_DRIVER_FW_PATH_PARAM := ""
endif



3.  Add android.hardware.wifi.direct.xml

PRODUCT_COPY_FILES += \
frameworks/native/data/etc/android.hardware.wifi.direct.xml:system/etc/permissions/android.hard
ware.wifi.direct.xml

4. init.xxx.rc

service rtw_suppl_con /system/bin/wpa_supplicant \
    -ip2p0 -Dnl80211 -c /data/misc/wifi/p2p_supplicant.conf -e/data/misc/wifi/entropy.bin -N \
    -iwlan0 -Dnl80211 -c/data/misc/wifi/wpa_supplicant.conf
    class main
    socket wpa_wlan0 dgram 660 wifi wifi
    disabled
    oneshot

service rtw_suppl /system/bin/wpa_supplicant -iwlan0 -Dnl80211
-c/data/misc/wifi/wpa_supplicant.conf
    socket wpa_wlan0 dgram 660 wifi wifi
    class main
    disabled
    oneshot

5. Set wifi.interface

PRODUCT_PROPERTY_OVERRIDES += \
 wifi.interface=wlan0

6. Apply wifi_realtek.c

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

7. wpa_supplicant_8

ifeq ($(BOARD_WIFI_VENDOR), realtek)
L_CFLAGS += -DREALTEK_WIFI_VENDOR
L_CFLAGS += -DANDROID_P2P
L_CFLAGS += -DCONFIG_ANDROID_4_2_PERSISTENT_IOT
Endif

8. Adding or Selecting Target Platform

opt/kernel_imx/drivers/net/wireless/rtl8723bs/makefile

CONFIG_PLATFORM_FSL_IMX6Q = y
CONFIG_PLATFORM_I386_PC          = n
CONFIG_PLATFORM_ANDROID_X86  = n
CONFIG_PLATFORM_ARM_S3C2K4  =  n
CONFIG_PLATFORM_ARM_PXA2XX  =  n
CONFIG_PLATFORM_ARM_S3C6K4  =  n
CONFIG_PLATFORM_MIPS_RMI
 =  n
CONFIG_PLATFORM_RTD2880B
 = n
CONFIG_PLATFORM_MIPS_AR9132  =  n
CONFIG_PLATFORM_MT53XX
 = n
CONFIG_PLATFORM_RTK_DMP
 = n

9. opt/kernel_imx/drivers/net/wireless/Makefile

obj-$(CONFIG_RTL8723AS) += rtl8723as/



10. opt/kernel_imx/drivers/net/wireless/Kconfig

source "drivers/net/wireless/rtl8723bs/Kconfig"



The build is building success, but i don't get the KO module file in opt/out/target/product/sabresd_6dq/system/lib/module/



Thank's a lot for any help or ideas!
