TI中文支持网nand write.e 和nand write.yaffs有什么区别啊？

能不能直接用nand write.e来烧写yaffs文件系统镜像呢？

直接用nand write和nand write.e可能也可以烧写成功，但容易产生坏块，用nand write.yaffs烧写更好

我昨天晚上用write.e烧写yaffs2文件系统映像到开发板中，出现了下面的错误：

请问一下，这是因为烧写命令的原因，还是根文件系统本身的原因啊？

一般可能是这两种情况：
1.需要使用nand write.yaffs命令烧写
2.mkyaffs2image工具或者制作时的参数为问题
可以先增加u-boot对nand write.yaffs的支持，这个网上的资料很多，如果还有错误，再检查工具。
