我是用SD卡启动linux以后可以通过mount挂在rootNFS到开发板，为什么不能启动呢？
        mmcargs=setenv bootargs console=${console} ${optargs} root=/dev/nfs nfsroot=192.168.1.103:/home/rootfs,nolock rw mem=512M vram=50M

搞笑，为什么要这样写呢？

mmcargs=setenv bootargs console=${console} ${optargs} root=/dev/nfs nfsroot=192.168.1.103:/home/rootfs,nolock rw mem=512M vram=50M

这个是AM335用的

1. setenv nfsarg 'setenv bootargs console=${console} root=/dev/nfs rw nfsroot=${serverip}:/home/boyie/evb-335/rootfs/rootfspda,nolock ip=${ipaddr}:${serverip}:${gatewayip}:${netmask}::eth0:off lcdtype=${lcdtype}'

都是自己用的 保证能用  内核记得勾上以太网设置里勾上 BOOTP 文件系统里勾上 NFS相关的
