之前已经PING过，ubuntu可以与开发板互相ping通；然后我是设置了开发板的U-BOOT参数之后，就启动不了了，错误如下：

就卡死在这里，启动不了了，有哪个哥们知道如何解决？

你的bootargs中的nfsroot和ip输入的是192.168.0.128，然而你的serverip设置的确实192.168.0.103.服务器那边的serverip使用的都不是一个IP

感谢，我的ubuntu上的ip是192.168.0.128；开发板的ip是192.168.0.103；
你的意思说我的serverip要设置为ubuntu的ip，是吗？

serverip要与Ubuntu系统的IP相同

U-boot下能ping通虚拟机吗？
