NFS方式mount主机根文件系统出错-优快云博客

Linux主机ip设置为192.168.0.77，通过u-boot设置开发板自身ip为192.168.0.78，按住PC机的空格键，复位开发板进入u-boot命令行方式，重新设置Linux的启动参数如下：

setenv linux_arg root=/dev/nfs nfsroot=192.168.0.77:/armsys2440/root ip=192.168.0.78:192.168.0.77:192.168.0.1:255.255.255.0:armsys.hzlitai.com:eth0:off console=ttyS0

保存设置后运行如下：

IP-Config: Complete:
      device=eth0, addr=192.168.0.78, mask=255.255.255.0, gw=192.168.0.1,
