本文档介绍了如何在s5pv210上配置和使用NFS根文件系统。步骤包括：通过make menuconfig启用网络支持和NFS文件系统，编辑.config设置启动参数，取消初始RAM文件系统支持，然后编译内核。成功启动后，显示了内核启动信息，并在NFS根文件系统中列出目录。

A)make menuconfig
(a）*] Networking support —>
Networking options —>
[*] IP: kernel level autoconfiguration
[*] IP: DHCP support
[*] IP: BOOTP support
[*] IP: RARP support

(b）File systems —>
[*] Network File Systems —>
[*] Root file system on NFS

B) vi .config
CONFIG_CMDLINE=”noinitrd mem=512M console=ttySAC2,115200 root=/dev/nfs nfsroot=172.16.96.215:/arm-nfs ip=172.16.96.250:172.16.96.215:172.16.96.215:255.255.254.0::eth0:off”

C)make menuconfig

general setup->
[ ] Initial RAM filesystem and RAM disk (initramfs/initrd) support(取消)

D）
make ;
uboot> tftp 30008000 zImage
uboot> bootm 30008000

结果如下：
Boot with zImage
The input address don’t need a virtual-to-physical translation : 30008000
