主机 ubuntu10.10。编译工具：arm-linux-gcc 4.3.3嵌入式平台s3c2440 内核linux。2.6.37.4。
刚拿到一个水星无线网卡。我的第一反应是拆开看看。瑞昱rtl8188cus的芯片、我看下网卡自带的光盘资料有linux下的驱动。里面一个word文档对我的帮助是很大的。how to support new platform。doc。会教你怎样修改makefile。首先把驱动文件copy到主机。修改makefile。CONFIG_PLATFORM_I386_PC = y
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
CONFIG_PLATFORM_ARM_TCC8900 = n
CONFIG_PLATFORM_ARM_MX51_241H = n
CONFIG_PLATFORM_ACTIONS_ATJ227X = n
CONFIG_PLATFORM_TI_DM365 = n
CONFIG_PLATFORM_RK2818 = n
CONFIG_PLATFORM_MIPS_JZ4760 = n。默认的是 i386——pc。根据自己的平台去选择。我的开发板是芯片s3c2440.我只需arm_S3C2K4=y,i386_pc=n;然后是去修改编译工具。内核路径。
ifeq ($(CONFIG_PLATFORM_ARM_S3C2K4), y)
EXTRA_CFLAGS += -DCONFIG_LITTLE_ENDIAN
ARCH := arm
CROSS_COMPILE := arm-linux-
KVER := 2.6.37.4
KSRC := /home/lilei/linux-2.6.37.4
endif
cross——complize 对应编译工具。kver对应的是内核版本。然后是ksrc是内核路径。这个一定不能搞错。好啦。makefile已经改完啦，是不是很简单啊。修改后make编译

下面还需要移植一个工具，wireless_tools.29.tar.gz。这个网上都能下到的，同样修改makefile
## Compiler to use (modify this for cross compile).
CC = arm-linux-gcc
## Other tools you need to modify for cross compile (static lib only).
AR = arm-linux-ar
RANLIB = arm-linux-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。下面要开始建立连接。
iwconfig wlan0 key #####
iwconfig wlan0 essid “网络名称”
下面可以通过iwconfig wlan0 看下连接状态

好啦。我先把开发板上的那个dm9000 网卡屏蔽掉。ifconfig eth0 down。
然后ping下192.168.1.1.我连的是无线路由器发射的网络。
[root@XC2440 /]# ifconfig eth0 down
[root@XC2440 /]# ping 192.168.1.1
