arm embeded linux nfs boot configure

1.> 配置kernel

1.> Enable nfs support and nfs root,if Root file system on NFS is invisible,please check whether enable "IP_PNP" option.Note: red part

│ │ --- Network File Systems

│ │ <*> NFS client support

│ │ [*] NFS client support for NFS version 3

│ │ [ ] NFS client support for the NFSv3 ACL protocol extension

│ │ [ ] NFS client support for NFS version 4 (EXPERIMENTAL)

│ │ [*] Root file system on NFS

Networking options

[*] TCP/IP networking

│ │ [*] IP: multicasting

│ │ [ ] IP: advanced router

│ │
[*] IP: kernel level autoconfiguration

2.>modify u-boot bootargs

setenv bootargs console=ttyS0,115200 reserved_fb=1 mem=256M
rootfstype=nfs root=/dev/nfs rw nfsroot=192.168.110.60:/home/victor/nfs,tcp,nfsvers=3,nolock,rsize=8192
init=/init kernel=0 ip=192.168.110.73:192.168.110.60:192.168.110.254:255.255.255.0::eth0:on

这部分有些参数，每个platform存在差异，与NFS有关的主要是红色部分。

3.>configure pc server nfs service

如果是UBUNTU，请安装sudo apt-get install nfs-kernel-server.确认是否可以在其它PC mount 成功，mount -t nfs
192.168.110.60:/home/victor/nfs /mnt
