nand write.e 和nand write.yaffs有什么区别啊？

    nand write：向Nand Flash写入数据，如果NandFlash相应的区域有坏块，则直接报错。
    nand write.e: 向Nand Flash写入数据减肥时会时行ECC校验，如果NandFlash相应的区域有坏块，可以跳过坏块。
    nand write.jffs2：向Nand Flash写入jffs2镜像到相应的分区。
    nand write.yaffs：同理，实现yaffs文件系统镜像的烧写，这个命令不一定所有版本的u-boot支持，有些版本可能需要自己手动添加

    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。
