Problem with wifi configuration RTL8723BS on IMX6 SabreSD Android

[majuani]

Hello All!

Have i.MX 6Quad Freescale SabreSD with Android 4.3

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!

[majuani]

For now i have :

If i set in vim device/fsl/{yourdevice}/BoardConfig.mk

BOARD_WIFI_VENDOR := realtek

Buiding success, but i don't get the KO module file.

if i set 

BOARD_WLAN_VENDOR := realtek

i get error 

make: *** No rule to make target `NOTICE-TARGET-STATIC_LIBRARIES-lib_driver_cmd_rtl', needed by `out/target/product/sabresd_6dq/system/bin/hostapd'. Stop.
make: *** Waiting for unfinished jobs....

for RALINK  and ATHEROS ar6003  is set like WLAN, but in documentation for RTL8723BS is set WIFI.

What correct wlan or wifi?

if correct WLAN, why i get "No rule to make target `NOTICE-TARGET-STATIC_LIBRARIES-lib_driver_cmd_rtl'"

Hi Ma

RTL8723 is not nxp product and not supported in nxp linux bsp releases.

It is pure linux problem with building driver. As a rule, chip vendors (realtek in this case) are

providing documentation for porting drivers for their products. Seems most appropriate

way to apply to realtek support:

Realtek

Again!!!!!! why my post is marked "CONSIDERS SOLVED" ???? NOT SOLVED!!!!

Stop to mark my quastions solved or CONSIDERS SOLVED. 

This is misleading people. You find the question in the search, you think there is a solution. And here it is not!

igorpadykov Every time you give advice like "read here", "maybe help here", "read on the page 56" and all that sort of thing.

There were gathered people who know how to use the search and read the documentation, asking the question they want to get help, not excuses.

[igorpadykov]

Hi Ma

I am afraid you are not right, even people know how to use the search and

read the documentation, it is difficult for them to sort out correct search result and

interpret documentation. For many people often it is not easy to find

necessary document and explanations in it.

Please note that this forum is devoted to nxp i.mx processors and generic

linux questions not related to i.mx may be answered on generic linux forums.

Flag "Considered solved" does not mean that issue is solved. There is another

flag : "Correct answer" meaning that issue is solved. Flag "Considered solved"

means that was provided best available answer.

Please note that NXP has special service for providing support with customer

software porting: Professional Services

Who decided that this is the best answer? 

I do not consider him the best. The best answer is when they give an answer or help with an excerpt from the code or from the documentation.. The best answer is not to redirect to another forum, redirect to "Professional Services" or read the documentation on page 55.

Entering to your profile,every one can see all the topics on which you "walked"
In each topic, you do not have a discussion on the problem, there is no excerpt from the code. You always simply indicate a link to the documentation or a similar topic "read there"

The best answer should be determined by the one who created the topic, and not the one who responded to it. You think in all topics your answers are the best, but this is not so and there is no help.

Hi Ma

as this is generic linux issue it could be posted on kernel mail list or

meta-fsl-arm mailing list, so that someone familiar with it could try to assist you.
