210的nfs挂载不上啊？

这是打开开发板在uboot里的显示：

不知道为什么？

这是我在设置nfs时的提示内容？
我感觉第二192.168.1.185应该是网关吧？我的网关是192.168.1.1。是不是这里出的问题啊？

setenv gatewayip 192.168.xx.xx   //设置网关
saveenv //保存
重启一下用print看下对应的项有没有修改成功。
不过那边看上去应该是已经 挂上了，只是init执行不成功。建议先用我们的文件系统与内核试下，还有文件系统权限应该修改权限chmod 777 xxx -R这种方式。

我是不是得先让开发板用板子的文件系统正常启动啊
？

我应该在哪里输入这个setenv gatewayip 192.168.xx.xx   //设置网关？
是在dnw里[root@EmbedSky /]# 这个里输入吗？

不是，在uboot界面中按q，会进入到 控制台了，不用启动系统。

哦了！好使了！谢谢您！

我也遇到了NFS挂载不了，系统启动完就停在那了

但是我试了设置setenv gatewayip 192.168.9.1还是这种现象，请问这是为啥呢？
