iMX6 NFS启动

iMX6 NFS启动

1、Tftp下载uImage：

1.1，设置ubuntu

(1) Setup tftp server files

# apt-get install tftpd tftp openbsd-inetd

(2) make a tftp directory Here we make /opt/tftpboot be a tftp directory.

# mkdir /opt/tftpboot

# chmod 777 /opt/tftpboot

(3) Open /etc/inetd.conf and edit it

# gedit /etc/inetd.conf

Add this line:

tftp dgram udp wait nobody /usr/sbin/tcpd /usr/sbin/in.tftpd /opt/tftpboot

(4)Restarting tftp service

#sudo /etc/init.d/openbsd-inetd restart

可以根据你的uImage文件放在路径，修改上述路径；也可以在/opt/tftpboot目录下生成一个目标连接文件。

1.2，tftp下载uImage

MX6Q SABRESD U-Boot >tftpboot uImage

2、文件系统以NFS方式加载

2.1 ，设置ubuntu

(1)， Install NFS server package
# apt-get install nfs-kernel-server
(2)， Configure portmap
# dpkg-reconfigure portmap
Select “NO”
(3) ，Configure mounted directory and authority
# gedit /etc/exports

Add the following line at the end of the file:
/home/ rootfs *(rw,sync,no_root_squash)
(4) ，Restart the NFS service
#sudo /etc/init.d/portmap restart
#sudo /etc/init.d/nfs-kernel-server restart

2.2，通过串口设置uboot变量设置

setenv ipaddr 192.168.1.xxx #设置板子IP

setenv serverip 192.168.1.xxx #设置为开发机的IP

setenv bootfile uImage

setenv nfsroot /home/rootfs

setenv bootargs_base 'setenv bootargs console=ttymxc0,115200'

setenv bootargs_nfs 'setenv bootargs ${bootargs} root=/dev/nfs ip=dhcp nfsrootdebug nfsroot=${serverip}:${nfsroot},v3,tcp fec_mac=${ethaddr} video=mxcfb0:dev=ldb,CVBS-TV,if=RGB666,bpp=16'

setenv bootcmd_net 'run bootargs_base bootargs_nfs;bootm'

setenv bootcmd 'tftpboot uImage; run bootcmd_net'

saveenv

重启板子即可。
