cd /usr/local/src

1 安装交叉工具链arm-linux-gcc-4.3.2.tgz
(1) tar zxvf arm-linux-gcc-4.3.2.tgz -C /
(2) gedit /etc/profile
     export PATH=/usr/local/arm/4.3.2/bin:$PATH
(3) source /etc/profile
(4) echo $PATH
     arm-linux-gcc -v

2 编译u-boot

(3) make zImage ARCH=arm CROSS_COMPILE=arm-linux-

4 制作yaffs2文件系统
(1) tar zxvf FileSystem-Yaffs2.tar.gz
(2) ./mkyaffs2image-nand2g FileSystem-Yaffs2 rootfs.yaffs2

5 一键烧写u-boot.bin(208KB)、zImage(3.46MB)、rootfs.yaffs2(136MB)到OK6410
