刚开始看手册nfs启动就成功了，也没在意，后来再想启动问题就一大串
开始的时候，输入以下命令
Supervivi>param set linux_cmd_line "console=ttySAC0 root=/dev/nfs nfsroot=192.168.1.23:/opt/FriendlyARM/mini2440/root_nfs ip=192.168.1.70:192.168.1.23:192.168.1.23:255.255.255.0:"
结果，出现以下信息

然后再把root_nfs挂载到目标板，，，再超级终端上输入以下命令出现错误
[root@FriendlyARM /]# mount -t nfs -o nolock 192.168.1.23:/opt/FriendlyARM/mini2
440/root_nfs /mnt
mount: 192.168.1.23:/opt/FriendlyARM/mini2440/root_nfs failed, reason given by s
erver: Permission denied
mount: nfsmount failed: Bad file descriptor
mount: Mounting 192.168.1.23:/opt/FriendlyARM/mini2440/root_nfs on /mnt failed:
Bad file descriptor
再在redhat上输入，也出现错误
[root@plg root]# mount -t nfs -o nolock 192.168.1.23:/opt/FriendlyARM/mini2440/root_nfs /mnt/nfs
mount: RPC：超时
狗日的搞了这么久突然想起什么，原来是配置linux主机的NFS系统配置错了，由于下了新内核用了root_qtopia,后来不知道为什新的编译链编译出来的可执行文件老不能执行，就统统换回老的了唯独nfs配置文件忘了，这东西一点都马虎不得
