说明：TQ2440的板子，Nand 是256M的
内核是：linux-2.6.30.4
用的是：busybox-1.21.0
生成文件系统的命令是：
mkyaffs2image /home/xuyuefei/MyLinux/rootfs/ /home/xuyuefei/MyLinux/root_fs.bin
烧写的u-boot是u-boot-1.1.6_W3520100601.bin
用提供的内核和文件系统都能起来；
用自己的内核和提供的文件系统也能起来；
自己的内核自己的文件系统错误信息下面贴出来了；
文件系统起不来，也没有出现：“Please press Enter to activate this console. ”
部分作出的修改如下制作后文件系统大小是90M

应该是挂成功了，只是可能文件系统做得不好，报了不小错
