x210 linux -qt wifi-8188eus 移植使用说明
www.9tripod.com huangdongchao 20141211
在x210 linux-qt中使用wifi模块8188eus的一些说明： （下面的操作都是在命令行中进行，包括pc的命令行和开发板的命令行）
注意：刘工之前也在论坛上发了类似的移植帖子，不过是在Android命令行；其实差不多；
可以进行参考：http://bbs.9tripod.com/thread-28064-1-1.html
http://blog.csdn.net/armeasy/article/details/6252389
步骤：
1、根据自己的开发环境情况，编译一个wlan.ko出来：
1）
解压rtl8188EUS.tar.bz2，修改里面的Makefile，修改的地方包括，交叉编译工具的路径，对应的内核的版本，对应的内核源码的路径，如下：（例子）
ifeq ($(CONFIG_PLATFORM_ARM_S5PV210), y)
EXTRA_CFLAGS += -DCONFIG_LITTLE_ENDIAN -DCONFIG_MINIMAL_MEMORY_USAGE
ARCH := arm
CROSS_COMPILE := /usr/local/arm/arm-2009q3/bin/arm-none-linux-gnueabi-
KVER := 2.6.35
KSRC := /home/hdc/x210/QT4.8/qt_x210v3/kernel
MODULE_NAME := wlan
endif
上面的交叉编译工具的路径，内核源码路径，具体要根据自己的开发环境情况做一些改动；
2）进入，命令行中输入：
./make_drv
Please select card type(1/2):
1) RTL8188eus
2) RTL8189es
#? 1 （输入1，选择8188）
You have selected RTL8188eus
rtw_version.h has existed!
接着，进行编译：
make
这样就生成了wlan.ko
2、操作wifi模块
1）把刚才编译出来的wlan.ko放到开发板中； （驱动文件较大，通过u盘拷贝，这样快些；）
2）加载驱动
insmod wlan.ko
[root@x210ii tmp]# insmod wlan.ko

可以看到现在wifi模块并没有启动；
那到底wifi模块的名称是什么？
上面加载wifi驱动时，可以看到信息为：wlan0
4）启动wifi模块：

可以看到wifi模块已经启动；
5）用wifi命令操作
这些命令包括iwlist iwconfig iwpriv iwspy等等，具体可以网上查询下；这里开发板上已经支持的命令有iwlist iwpriv iwspy；（其它没支持的，可以自己移植）
使用iwlist查看周围的wifi AP：

可以看到一堆的AP；
6）使用wifi上网：
需要用到wpa_supplicant工具；（这个开发板已经支持；如没支持，自己可以下载源码包移植）
在开发板的/etc中建立wpa_supplicant.conf文件，里面内容为：（开发板已经有这个文件，改动下即可）
ctrl_interface=/var/run/wpa_supplicant
ap_scan=1
network={
ssid="9tripod" （这是要连的wifi ap）
scan_ssid=1
key_mgmt=WPA-EAP WPA-PSK IEEE8021X NONE
pairwise=TKIP CCMP
group=CCMP TKIP WEP104 WEP40
psk="9tripodok" （对应的ap的密码）
}
然后创建文件夹：
mkdir -p /var/run/wpa_supplicant
接着进行连接：
wpa_supplicant -Dwext -iwlan0 -c/etc/wpa_supplicant.conf &
（USB wifi支持80211和wext两种规范，rt8188eus有多个驱动版本，请使用支持wext较好的）

若是不成功，报错如下：
ioctl[SIOCSIWENCODEEXT]: Invalid argument
然后移植循环；
这时，建议是换一个wifi驱动的源码包，重新编译一个wlan.ko;
我这里就是遇到这个问题，然后换一个源码包编译即可：
用的源码包改为：
rtl8188EUS_linux_v4.1.4_6773.20130222.tar.gz
改动Makefile，可以参照上面的改动；然后make即可；
接着重复上面的过程；即可连接成功；
上网操作：
设置wlan0的ip，这里设置为固定ip；也可以设置为动态ip；
[root@x210ii tmp]# ifconfig wlan0 192.168.0.169

若是要直接ping网址，则需另外加网址解析的脚本语句；这里不多说；
[root@x210ii tmp]# ping www.baidu.com
ping: bad address 'www.baidu.com'
（没加前，ping网址是失败的；）
