文件系统移植不成功？

我按照移植手册上的移植，做完step11 把制作好的文件系统下载进开发板，挂载不成功，不知道什么原因，串口信息如下：

补充点：构建文件系统时 /etc中的内容，我是直接复制的天嵌提供的源码中/etc的内容。。。

建议你，按照教程认真再做一遍，直接修改天嵌提供的文件系统，可能是你的zImage有问题，所以再配置下，我也遇到过这个问题，还有我用linux-2.6.30.4_20100531.rar也是不行，换了就好了

我也遇到相同的问题。不知道问题出在哪里？

4# chqsy


这些问题都有老的帖子归结过。
也有很多的原因引起。
我的建议是测试行的找答案吧。如果都换了内核，文件系统，
你还是用天嵌的内核+你的文件系统 来看看能不能运行，这样才能把你的范围缩小

5# embedsky_lxt


我用天嵌提供的内核+我自己制作的可以运行。。。也就是说我制作的内核有问题！可是我完全按照移植手册上一步一步来的啊 ....。。哪地方会有问题呢？？？

6# cools1860


嗯，你再对比一下你的选项，和天嵌的吧。相信你会找到答案
