我又试了一次，把环境变量bootargs后面加了一个 rootfstype=yaffs2第一个错误就没有了，但第二个错误还存在。

我用的双系统。QQ不能远程。。

shufexiu · 发表于 2011-2-16 12:15:49

在我看来你的分区信息不对了。你最后那个yaffs分区结束点为 10200000
已经查出了范围，你将其设置为500000
而不知道你的uboot写的设置不知道是不是也这样

非常感谢你的回答；但是改过来之后烧进nand 还是不对；
我的nand是256M 的  。mtd分区还是按256M 来分的；
我的uboot是在nor flash 中，通过run bootcmd引导nand中的内核;
启动信息如下：

你是自己制作文件系统而已还是内核也自己移植。
如果是请注意一下

文件系统和内核都是自己做的。弄了近一个星期了，还是挂不起文件系统。
晚上回家试一下！:)

对了，下面这个选项是要选中还是不选中呢？
