制作yaffs 文件系统时用 mkyaffs2image 命令， mkyaffsimage_2 针对Nand flash 是64M的。你的nand flash应该是128

遇到这样问题的网友可以根据下面的建议逐个检查。

1. bin/busybox文件是可以执行的。
2. 在配置busybox的时候要选中shell选项中的一个选项
3. linuxrc 是可执行的。
4. 制作文件系统的时候利用的工具也要留意区分：
    mkcramfs                制作cramfs镜像的工具
    mkimage                        制作jffs2镜像的工具
    mkyaffs2image                制作2.6的yaffs2的镜像工具（针对Nand Flash是128MB到1GB的）
    mkyaffsimage                制作2.6.13的yaffs2的镜像工具
    mkyaffsimage_2                制作2.6.25.8或2.6.30.4或更高版本内核的yaffs2的镜像工具（针对Nand Flash是  64MB的）
4. 你使用的是256MB的Nand Flash，而在配置内核的nand时选择ecc校验

M的吧。

这个我已经一一查过了，但是还是不行！
