自己移植linux的内核，我从yaffs2启动可以挂载主机上的nfs，mount -o nolock -t nfs 192.168.1.111:/opt/FriendlyARM/mini2440/root_qtopia /mnt
但是为什么我设置参数启动从nfs启动就不行呢？是不是我的DM9000驱动移植还有问题？
param set linux_cmd_line "console=ttySAC0 root=/dev/nfs nfsroot=192.168.1.111:/opt/FriendlyARM/mini2440/root_qtopia/ ip=192.168.1.230:192.168.1.111:192.168.1.111:255.255.255.0:sbc2440.arm9.net:eth0:off"
我的启动信息如下：
