若格的全志R8开发板配置为rtl8188eus

2017/4/20 17:54

版本：V1.0

请严重注意（这个坑全志的文档不会告诉你的！！！！^_）：

R:\wyb\rtl8188eus_r8_20160613_ruoge\lichee\tools\pack\chips\sun5i\configs\r8-evb\sys_config.fex

修改完工之后的结果：

;2017/4/20 16:43 wenyuanbo for rtl8188eus

[usb_wifi_para]

（依葫芦画瓢，这里还是选择使用：）

usb_wifi_used = 1

（这里填写的USB的WIFI：rtl8188eus所使用USB端口号，而不是USB端口的总数，切记！！！！）

usb_wifi_usbc_num = 1

由于asource上面没有找到全志R8的WiFi移植说明书，

http://asource.allwinnertech.com:9080/

因此本文参照全志R16平台：R16 WiFi移植说明书.pdf

1、（确保将rtl8188eus选中为编译成模块：）

rootroot@rootroot-E400:~/wyb/rtl8188eus_r8_20160613_ruoge/lichee$ ./build.sh config

Welcome to mkscript setup progress

rootroot@rootroot-E400:~/wyb/rtl8188eus_r8_20160613_ruoge/lichee$ cd linux-3.4/

rootroot@rootroot-E400:~/wyb/rtl8188eus_r8_20160613_ruoge/lichee/linux-3.4$ make ARCH=arm menuconfig

Device Drivers --->

[*] Network device support --->

[*] Wireless LAN --->

（已经默认选中了：）

<M> Realtek 8188E USB WiFi

（这里取消选中：）

< > Eagle esp8089 WLAN driver

2、关闭rtl8192cu，打开rtl8188eu：

R:\wyb\rtl8188eus_r8_20160613_ruoge\android\device\softwinner\nuclear-evb\BoardConfig.mk

# realtek wifi support "sta/softap/wifi direct" function

# 1. enable BOARD_WIFI_VENDOR := realtek below

# 2. use nl80211 instead of wext interface in wpa_supplicant service@init.sun5i.rc

# 3. add android.hardware.wifi.direct.xml file to system/etc/permissions/

# 4. add interface for softap tether in the overylay/.../value/config.xml

# rtl8192cu: set SW_BOARD_USR_WIFI and BOARD_WLAN_DEVICE "rtl8192cu"

# rtl8188eu: set SW_BOARD_USR_WIFI and BOARD_WLAN_DEVICE "rtl8188eu"

BOARD_WIFI_VENDOR := realtek

ifeq ($(BOARD_WIFI_VENDOR), realtek)

WPA_SUPPLICANT_VERSION := VER_0_8_X

BOARD_WPA_SUPPLICANT_DRIVER := NL80211

BOARD_WPA_SUPPLICANT_PRIVATE_LIB := lib_driver_cmd_rtl

BOARD_HOSTAPD_DRIVER := NL80211

BOARD_HOSTAPD_PRIVATE_LIB := lib_driver_cmd_rtl

（关闭这里：）

#SW_BOARD_USR_WIFI := rtl8192cu

#BOARD_WLAN_DEVICE := rtl8192cu

（打开这里：）

SW_BOARD_USR_WIFI := rtl8188eu

BOARD_WLAN_DEVICE := rtl8188eu

endif

3、（有关，但是不需要修改：）

R:\wyb\rtl8188eus_r8_20160613_ruoge\android\device\softwinner\nuclear-evb\init.sun5i.rc

已经配置好了：

# 1.1 realtek wifi sta service

service wpa_supplicant /system/bin/wpa_supplicant -iwlan0 -Dnl80211 -c/data/misc/wifi/wpa_supplicant.conf -e/data/misc/wifi/entropy.bin

class main

socket wpa_wlan0 dgram 660 wifi wifi

disabled

oneshot

# 1.2 realtek wifi sta p2p concurrent service

service p2p_supplicant /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

4、（不需要修改：）

R:\wyb\rtl8188eus_r8_20160613_ruoge\android\device\softwinner\nuclear-evb\nuclear_evb.mk

没有发现WIFI的配置。

5、（不需要修改：）

R:\wyb\rtl8188eus_r8_20160613_ruoge\android\device\softwinner\nuclear-evb\overlay\frameworks\base\core\res\res\values\config.xml

有这个配置文件：

<!-- List of regexpressions describing the interface (if any) that represent tetherable

Wifi interfaces. If the device doesn't want to support tethering over Wifi this

should be empty. An example would be "softap.*" -->

<string-array translatable="false" name="config_tether_wifi_regexs">

</string-array>

参考资料（通过出错的DEBUG调试信息分析出错的原因的过程！！！！）

如果在sys_config.fex中不配置usb_wifi_usbc_num，就会看到出错信息：

初步分析，在sys_config.fex中加入选项：

;2017/4/20 16:43 wenyuanbo for rtl8188eus

[usb_wifi_para]

usb_wifi_used = 1

usb_wifi_usbc_num = 2

继续出错：

初步判定usb_controller_type出错为配置成了第三个USB口，但是全志R8只有两个USB口，就出错了。
