以上是打印信息，到最后一步就重启uboot了，不知道是什么原因，哪位高手帮忙看看啊。。。。谢啦

错误信息：Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(2,0)

无法挂载文件系统到unknown-block(2,0),说明你的MTD分区修改好，重新设置一下MT分区。

..........祝你成功！

[marven]

可能是root文件系统的问题 或者内核配置的时候选择与文件系统有关的设置有误。重新配置内核

[ezword]

noinitrd root=/dev/mtdblock2 init=/linuxrc console=ttySAC0
这行参数的问题

说的好像是内核崩溃吧！我的和你的是一模一样的！正在解决，我同学有的就一次性成功了！

[雨焰]

我要是成功了的话，又想起你的话，我就给你说一下我的做法！要是我想不起来的话....！
