移植ubuntu到i.mx6ull --1

mumu_A

简介说明：
MY-IMX6-CB140P-6Y2D-256M-4G：(6Y2D是IMX6ULL，256M是内存，4G是EMMC)
安装ubuntu或debian建议存储是EMMC，这样容量大。1.下载Ubuntu系统和修改相关配置
首先创建保存路径
$ mkdir ~/image

$ cd image

$ mkdir ubrfs16.04.4

$ cd ubrfs16.04.4

下载ubuntu-base-16.04.4-base-armhf.tar.gz

$ wget http://cdimage.ubuntu.com/ubuntu ... 4-base-armhf.tar.gz

使用sudo 解压：

$ sudo tar zxf ubuntu-base-16.04.4-base-armhf.tar.gz

安装qemu-user-static工具

$ sudo apt-get install qemu-user-static

拷贝qemu-arm-static到刚刚解压出来的目录

$ sudo cp /usr/bin/qemu-arm-static ./usr/bin/

网络配置

修改根文件系统软件源

$ sudo vim ./etc/apt/sources.list

添加 ubuntu arm 源(也可在网上找其他的arm源)

deb http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial main multiverse restricted universe

deb http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-backports main multiverse restricted universe

deb http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-proposed main multiverse restricted universe

deb http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-security main multiverse restricted universe

deb http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-updates main multiverse restricted universe

deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial main multiverse restricted universe

deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-backports main multiverse restricted universe

deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-proposed main multiverse restricted universe

deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-security main multiverse restricted universe

deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ xenial-updates main multiverse restricted universe

为了制作成功的根文件系统能够联网，可以直接拷贝本机的dns配置文件到根文件系统的相应位置

$ sudo cp /etc/resolv.conf ./etc/resolv.conf

首先在本机挂载刚刚下载好的文件系统，联网完成相应的配置，然后载烧录到开发板上。

需要挂载proc, sys, dev, dev/pts等文件系统。

编写一个bash脚本ms.sh来完成挂载和卸载操作，首先回到ubrfs16.04.4的上一级目录，并创建ms.sh文件，

$ cd ~/image

$ vim ms.sh

创建ms.sh文件内容如下：

#!/bin/bash

mnt ()

{

    echo "MOUNTING"

    sudo mount -t proc /proc ${2}proc

    sudo mount -t sysfs /sys ${2}sys

    sudo mount -o bind /dev ${2}dev

    sudo mount -o bind /dev/pts ${2}dev/pts      

    sudo chroot ${2}   

}

umnt ()

{

    echo "UNMOUNTING"

    sudo umount ${2}proc

    sudo umount ${2}sys

    sudo umount ${2}dev/pts

    sudo umount ${2}dev

}

if [ "$1" = "-m" ] && [ -n "$2" ];

then

    mnt $1 $2

    echo "mnt -m pwd"

elif [ "$1" = "-u" ] && [ -n "$2" ];

then

    umnt $1 $2

    echo "mnt -u pwd"

else

    echo ""

    echo "Either 1'st, 2'nd or bothparameters were missing"

    echo ""

    echo "1'st parameter can be one ofthese: -m(mount) OR -u(umount)"

    echo "2'nd parameter is the full pathof rootfs directory(with trailing '/')"

    echo ""

    echo "For example: ch-mount -m/media/sdcard/"

    echo ""

    echo 1st parameter : ${1}

    echo 2nd parameter : ${2}
