在ARM上安装USB无线网卡驱动过程（8188eu）

1、首先在下载对应的驱动源码包：

下载地址：http://download.csdn.net/detail/zzz_mraz/5262010

2. 解压该文件夹：tar xvzf rtl8188eu_USB_linux.tar.gz

3. 进入给文件夹修改Makefile文件。

修改如下：

a、平台选择：CONFIG_PLATFORM_I386_PC = n        CONFIG_PLATFORM_ARM_S3C2K4 = y

b、修改使用的编译工具、对应的内核目录：

[objc] view plain copy

 print?

1. ifeq ($(CONFIG_PLATFORM_ARM_S3C2K4), y)  
2. EXTRA_CFLAGS += -DCONFIG_LITTLE_ENDIAN  
3. ARCH := arm  
4. CROSS_COMPILE := /usr/local/arm/4.2.2-eabi/usr/bin/arm-linux-  
5. # KVER  := 2.6.24.7_$(ARCH)  
6. KSRC := /home/uni/workspace/20141107_yisuo/linux_3_6/linux-3.6  
7. endif  

c、PS：先把节能功能取消了CONFIG_POWER_SAVING = n

主要修改KVER:=2.6.38

KSRC :=/opt/FriendlyARM/mini6410/linux/linux-2.6.38

配置好上述选项，make后就得到驱动模块：8192cu.ko

生成8188.ko文件后，将其下载到mini6410开发板上，拷贝到/home文件夹下

2、模块加载：

执行insmod 8188eu.ko可以看到如下信息：
