TQ3358 NFS root问题

我的TQ3358开发板，能够手动添加NFS（用mount命令）。但是不能用nfs root（会报错然后就死机了），是什么原因啊？
我是严格按照手册操作的，是用SD卡启动。

问题解决了。
出在boot启动参数设置里面，复制/opt/EmbedSky/TQ3358/rootfs_TQ3358_linux_nfs就可以了。

亲，你至少帖点出错信息嘛，你这么说谁能知道是啥问题？？？？？？？？？？

直接在开发板上用mount 将/opt/EmbedSky/TQ3358/rootfs_TQ3358_linux_nfs 这个目录mount到板子上？

用mount命令是可以手动加NFS的。但是不能用NFS作为root文件系统！

出在boot启动参数设置里面，复制/opt/EmbedSky/TQ3358/rootfs_TQ3358_linux_nfs就可以了。

果然可以，我在用的时候业出现这个问题，并且用楼主的方法搞定的。主要是之前在测试的时候改过nfs的boot参数。
