标题: nfs挂载新的文件系统
主机平台: UBUNTU16.04
硬件平台:明远智睿MY-IMX6-EK200-6Q-1G
内核版本 :Linux-3.0.35
文件系统:rootfs-linux-minimal.tar.bz2

首先,需要在设置虚拟机的网络,桥接以太网,使虚拟机与开发板在同一网关下且虚拟机与开发板能够相互ping通
[attach]752[/attach]


设置ubuntu的ip为:192.168.18.88
查看虚拟机与开发板是否能相互ping通
虚拟机上执行
$ ping 192.168.18.99
开发板上执行:
#ifconfig eth0 192.168.18.99
#ping 192.168.18.88

能够相互ping通后,虚拟机上执行

$sudo vim /etc/exports
在最下面添加==>/home/jj/share *(rw,sync,no_root_squash)
虚拟机重启nfs服务
$ sudo /etc/init.d/nfs-kernel-server restart


重新开启开发板,进入uboot命令行
设置
>setenv ipaddr=192.168.18.99
>setenv serverip=192.168.18.88
>setenv nfsroot=/home/jj/share
>setenv netmask=255.255.255.0
>setenv netdev=eth0
>setenv ethaddr=00:01:02:03:04:05

再次
>ping 192.168.18.88
确定ping通

FEC: Link is Up ffff
Using FEC0 device
host 192.168.18.88 is alive

然后执行

>setenv bootcmd_mmc 'run bootargs_base bootargs_nfs; mmc dev 2; mmc read ${loadaddr} 0x800 0x2000; bootm'

>boot

接下来进入到文件系统开机中打印的字符:
mmc2(part 0) is current device
