rk3288_lubuntu_img制作步骤

1#刷Firefly-RK3288_Android4.4_201412290906.img

启动后刷linux-boot-miniroot.img 写到 recovery 分区，misc.img 写到 misc 分区。

2#建立TF

a,插TF到rk3288,  fdisk  -l

b,fdisk /dev/mmcblk1

       d (选择d,w删除所有分区)

       选择n   新建一个分区，

         fdisk   /dev/mmcblk1  -l

         mkfs.ext4 -E nodiscard /dev/mmcblk1p1     //格式化此分区

mount /dev/mmcblk1   /mnt

3#设置网络

miniroot#  udhcpc

4#下载ubuntu-core-armf.tar.gz

wget -P /mnt http://cdimage.ubuntu.com/ubuntu-core/releases/14.04/rele
ase/ubuntu-core-14.04-core-armhf.tar.gz

5#指定ttyFIQ0

2# 添加ubuntu1404-core  串口登录问题

$ sudo vi etc/rc.local

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
start ttyFIQ0

exit 0

6#$ sudo vi /etc/init/ttyFIQ0.conf   //内容如下：

# console - getty
#
# This service maintains a getty on console from the point the system is
# started until it is shut down again.

#add "-a root" for console root
start on stopped rc RUNLEVEL=[2345] and container CONTAINER=lxc

stop on runlevel [!2345]

respawn
exec /sbin/getty -a root -L 115200 ttyFIQ0 vt100 

7##设置ubuntu_root  网络

root@rk3288:~# echo auto eth0 > /etc/network/interfaces.d/eth0
root@rk3288:~# echo iface eth0 inet dhcp >> /etc/network/interfaces.d/eth0
root@rk3288:~# ln -fs ../run/resolvconf/resolv.conf /etc/resolv.conf
root@rk3288:~# ifup eth0

9#ubuntu 自动进入desktop ,

 要使用root自动登录，需要修改三个地方：

• 1.sudo passwd root
• 2.sudo passwd root --unlock
• 3.修改脚本

vi /etc/lightdm/lightdm.conf.d/20-lubuntu.conf

[SeatDefaults]
autologin-user=root
autologin-user-timeout=0
user-session=Lubuntu

10#Ubuntu14.04 root登陆错误“Error found when loading /root/.profile

vi /root/.profile

/*最后一行modify to*/
msg n

modify to

tty -s && mesg n

ubuntu修改用户名


正确的命令为:


id user_old


usermod -m -d /home/user_new -u 1001 user_old;
或
usermod -d /home/user_new -m -u 1001 user_old;
最后,再改变用户名和组名为user2:
usermod -l user_new user_old;


groupmod -n user_new user_old




id dou
root@rk3288:~# id dou
uid=1000(dou) gid=1000(dou) groups=1000(dou),27(sudo)
