  mount -t proc /proc /home/arjun/linux/nfs/ubuntu_rootfs/proc
  mount -t sysfs /sys /home/arjun/linux/nfs/ubuntu_rootfs/sys
  mount -o bind /dev /home/arjun/linux/nfs/ubuntu_rootfs/dev
  mount -o bind /dev/pts /home/arjun/linux/nfs/ubuntu_rootfs/dev/pts
  chroot /home/arjun/linux/nfs/ubuntu_rootfs

 #!/bin/bash
 echo "UNMOUNTING"
 umount  /home/arjun/linux/nfs/ubunturootfs/proc
 umount  /home/arjun/linux/nfs/ubunturootfs/sys
 umount  /home/arjun/linux/nfs/ubunturootfs/dev
 umount  /dev/pts /home/arjun/linux/nfs/ubuntu_rootfs/dev/pts
 

挂载
./mount.sh

apt update   
apt install vim
apt install kmod
apt install net-tools
apt install ethtool
apt install ifupdown
apt install language-pack-en-base
apt install rsyslog
apt install htop
apt install iputils-ping

 

设置本机名称和IP地址

echo "arjun_imx6ull">/etc/hostname
echo "127.0.0.1 loaclhost">>/etc/hosts
echo "127.0.0.1 arjun_imx6ull">>/etc/hosts

 

启动uboot修改bootargs参数

bootargs=console=tty1 console=ttymxc0,115200 root=/dev/nfs rw nfsroot=192.168.8.57:/home/arjun/linux/nfs/ubuntu_rootfs  ip=192.168.8.60:192.168.8.57:192.168.8.1:255.255.255.0::eth0:off

添加文件/etc/init/ttymxc0.config

start on stopped rc RUNLEVEL=[2345] and container CONTAINER=lxc
stop on runlevel[!2345]
respawn
exec /sbin/getty -L 115200 ttymxc0 vt100

再执行                

ln -s /lib/systemd/system/[email protected] /etc/systemd/system/getty.target.wants/[email protected]
