TI中文支持网我用的是Appro DM368的开发板，基于Appro的 IPNC RDK 5.0版本编译了一个内核，然后配置开发板NFS启动
重启后，输出了一堆的东西

有没有人帮我解释一下是什么原因导致的啊，我的NFS server 跟开发板连的一个交换机
kooking：
nfs连接不好，一般是网络拥塞、服务器过载或者网卡丢包，nfs是udp协议，你换tcp试试：
nfsroot=xx.xx.xx.xx:/rootfs,proto=tcp,nfsvers=3,nolock
orlando chen：
回复 kooking:
我在bootargs 加入了如下参数
mem=48M console=ttyS1,115200n8 noinitrd rw root=/dev/nfs nfsroot=$(nfshost):$(rootpath), intr, nolock, rsize=1024, wsize=1024, proto=tcp, nfsvers=3 ip=192.168.1.140:192.168.1.139:192.168.1.1:255.255.255.0:::off eth=00:0C:0C:02:3A:58
已经指定了tcp协议传输，但是结果还是一样
kooking：
回复 orlando chen:
可以用一台小交换机连接host和board，如果是因为网络原因，这样应该就没有问题。
还有可能就是host环境有问题，换一台host试试
jayson jang：
我有遇到过，是由于自己的服务器IP与网络内另一台PC的IP一样，导致NFS失败，可以改下host的IP试试
jayson jang：
回复 orlando chen:
把serverip设置成配置文件中的IP了？
