RTL8188CU在bb black上的移植---fwqlzz love is for ever

下载http://pan.baidu.com/s/1c27EdZa

在makefile下添加CONFIG_PLATFORM_ARM_AM335X = y


;然后是去修改编译工具。内核路径。


ifeq ($(CONFIG_PLATFORM_ARM_AM335X), y)
EXTRA_CFLAGS += -DCONFIG_LITTLE_ENDIAN
ARCH := arm
CROSS_COMPILE := arm-linux-gnueabihf-
KVER  := 3.2.0
KSRC := /home/raymon/work/linux-3.2.0
endif

将生成的.ko 下载到 bbb

开启wlan0
root@ok335x:/# ifconfig wlan0 up

在WPA下，需要安装4个开发工具

下载wireless_tools.29.tar.gz（支持wep），这个网上都能下到的，修改makefile 

## Compiler to use (modify this for cross compile).
CC = arm-linux-gnueabihf-gcc
## Other tools you need to modify for cross compile (static lib only).
AR = arm-linux-gnueabihf-ar
RANLIB = arm-linux-gnueabihf-ranlib

make 编译。会生成iwpriv,iwconfig,iwlist,iwspy,copy这些文件到开发板/sbin 目录下。同时copy同目录下的libiw。so。29到开发板/lib 目录下

下载libnl-1.1.4.tar.gz

tar xzf libnl-1.1.4.tar.gz 
cd libnl-1.1.4/
CC=/home/raymon/work/linux-devkit/bin/arm-linux-gnueabihf-gcc ./configure --prefix=$PWD/_install --host=arm-linux-gnueabihf
make
make install
之后将生成的库文件和头文件复制到交叉编译路径：
cp -rf _install/* /home/raymon/work//linux-devkit/arm-arago-linux-gnueabi/usr/

 下载openssl-0.9.8e.tar.gzwireless_tools.29.tar.gz。

将wpa_supplicant中的补丁拷贝到openssl中 
        # cp wpa_supplicant-0.7.3/patches/openssl-0.9.8e-tls-extensions.patch openssl-0.9.8e/
        #cd openssl-0.9.8e
        #mkdir /usr/local/ssl
        #vim Makefile
                CC= arm-linux-gnueabihf-gcc
                AR= arm-linux-gnueabihf-ar $(ARFLAGS) r
                RANLIB= arm-linux-gnueabihf-ranlib
                INSTALLTOP=/usr/local/ssl
                OPENSSLDIR=/usr/local/ssl
        #make 
        #make install

在/usr/local/ssl目录下安装了ssl库
 #ls /usr/local/ssl #bin  certs  include  lib  man  misc  openssl.cnf  private

下载wpa_supplicant-2.3.tar.gz （openssl用到0.7.3提供的补丁）

进入wpa_supplicant-0.7.3.tar.gz解压生成的wpa_supplicant-0.7.3/wpa_supplicant目录中：
        #cp defconfig        .config
        #vim .config
                CC=arm-linux-gnueabihf-gcc  -L/usr/local/ssl/lib/
          #CC=/opt/brcm/hndtools-mipsel-uclibc/bin/mipsel-uclibc-gcc
CFLAGS += -I/usr/local/ssl/include
#CPPFLAGS += -I../src/include -I../../src/router/openssl/include
LIBS += -L/usr/local/ssl/lib
        #make

经过编译后的wpa_supplicant源程序可以看到两个主要的可执行工具：wpa_supplicant和wpa_cli。wpa_supplicant是核心程序，它和wpa_cli的关系就是服务和客户端的关系：后台运行wpa_supplicant，使用wpa_cli来搜索、设置、和连接网络。

配置wpa_supplicant
在板子根目录nfsroot/etc中修改wpa_supplicant.conf文件


文件内容如下
ctrl_interface=/var/run/wpa_supplicant


network={
                ssid="RIMMS"     //填写无线网络的的用户名
                key_mgmt=WPA-PSK
                proto=WPA
                pairwise=TKIP
                group=TKIP
                psk="1234567890" //填写密码
}
注意要与你的无线路由中的设置对应。

测试
insmod 8192cu.ko
ifconfig wlan0 up
iwconfig wlan0 essid  RIMMS
wpa_passphrase RIMMS 1234567890 >> /etc/wpa_supplicant.conf


之后wpa_supplicant.conf中会添加以下内容，然后把最后面的经过加密的密码修改到上面去，再把下面的内容删掉！
network={
      ssid="RIMMS"
      #psk="1234567890"
      psk=4b2bc7cbb3710e9ea43f09e8d57e8bdb3b2a2127af44960d73216c3612f6baba
}
如:
network={
                ssid="RIMMS"     //填写无线网络的的用户名
                key_mgmt=WPA-PSK
                proto=WPA
                pairwise=TKIP
                group=TKIP
                psk=4b2bc7cbb3710e9ea43f09e8d57e8bdb3b2a2127af44960d73216c3612f6baba                
                #psk="1234567890" //填写密码
}
