Build NFS for the Development Board through Ubuntu

GenerallyNFSFile System to develop and test your ownProgramIf each change is made on the Development BoardU-bootBurnedNAND FlashThe above statement wastes a lot of time, so you must set it before development.NFSFile System:

 

COMPUTER:Ubuntu 12.04

Target Board:Ok6410

1. Enable the computerNFSService

1 ).InstallNFS:Sudo apt-Get install nfs-kernel-Server

2 ).ModifyNFSOfConfigFile: file directory/Etc/exports,InExportsAdd the target board to the fileNFSFile System Path and various options,The content is as follows:

/Home/CSB/code/2440 rootfs * (RW, insecure, sync, all_squash )#This isTq2440Of

/Home/CSB/code/6410 rootfs * (RW, insecure, sync, all_squash) # ok6410OfNFS

After modification, useSourceCommand to make the settings take effect:Sudo source/etc/exports

3 ).RestartNFSService

Sudo service Portmap restart

Sudo service nfs-kernel-server restart

4 ).Test successful

Showmount-eThe following content will appear

CSB @ csb-ThinkPad-Edge-E430c :~ $ Showmount-e

Export list for csb-ThinkPad-Edge-E430c:

/Home/CSB/code/6410 rootfs *

/Home/CSB/code/2440 rootfs *

The operation is successful.

5 ).Set a wired NicIP

Generally, the network cable is used to connect the network port of the computer to the target network port, and then the computerIPStatic addressIP
