RT3070 imx28 SoftAP功能移植。

分类： LINUX

/opt/freescale/usr/local/gcc-4.4.4-glibc-2.11.1-multilib-1.0/arm-fsl-linux-gnueabi/bin/arm-linux-strip udhcpd

1.#PATH=$PATH:/etc/apache/bin

/home/liyun/work/ltib/rpm/BUILD/linux-2.6.35.3

/home/liyun/maye9/ltib/rpm/BUILD

一：DHCP服务器端:(编译器）
1. 修改Makefile: 添加: CROSS_COMPILE=arm-linux-

2. #make , 把生成的dhcpd文件下载到板子上.

make LDFLAGS="-static"

我编译时提示有个C文件出错，是因为文件中switch case 少了个break。
使用/usr/local/arm/2.95.3/bin/arm-linux-strip处理一下，

3. #cp samples/udhcpd.conf /etc/ #copy udhcp/samples下的文件到目标板子的 /etc目录

4. # vi /etc/udhcpd.conf: 修改如下:

3 # The start and end of the IP lease block
4
5 start 192.168.1.20 #default: 192.168.0.20 为winXP的ip地址范围
6 end 192.168.1.25 #default: 192.168.0.254

9 # The interface that udhcpd will use
10
11 interface wlan0 #default: eth 0#目标板子上的无线网卡wlan0 ，按照实际情况改写如ra0等

85 #Examles
86 opt dns 222.201.130.30 222.201.130.33   #dns服务器
87 option subnet 255.255.255.0
88 opt router 192.168.1.10                       #wlan的 ip地址,做为网关地址
89 #opt    wins    192.168.10.10              #注释掉
90 option dns 192.168.1.10 # appened to above DNS servers for a total of 3
91 option domain local
92 option lease   864000      # 10 days of seconds

5# ./dhcpd //运行dhcpd服务器

到此DHCP服务器运行成功。

二：SoftAP功能移植。

搜索到解决方法：

The "disagrees about version of symbol" errors seem to imply that your kernel and atl1c modules were built with different compiler versions or very different configurations.

Try rebuilding the kernel (including the Atheros/Attansic modules) from scratch:
make clean
make
make modules_install

Strange, the --clean argument should have helped. But perhaps doing the following will make a difference:

1. back up your kernel .config file (cp /usr/src/linux/.config /usr/src/my.config)
2. cd /usr/src/linux; make mrproper
3. restore the .config file (cp /usr/src/my.config /usr/src/linux/.config)
4. and finally, run genkernel.

是因为用错了kernel，要保持和编译过的kernel移植，包括编译器版本。

把udhcpd.conf中的 interface wlan0 #default: eth 0 改为ra0.
