描述

创建 Ubuntu 根文件系统
准备工作
安装qemu

在Linux PC主机上安装模拟器:

mkdir temp sudo tar -xpf ubuntu-base-16.04.1-base-arm64.tar.gz -C temp
修改根文件系统
准备工作

准备网络:

sudo cp -b /etc/resolv.conf temp/etc/resolv.conf

准备qemu

sudo cp /usr/bin/qemu-aarch64-static temp/usr/bin/

进入根文件系统进行操作:

sudo chroot temp
更新及安装

更新:

apt update apt upgrade

安装自己需要的功能

apt install vim git ....(根据自己需求添加)

安装xubuntu

apt-get install xubuntu-desktop apt-get install udev

可能出现错误:

E: Unable to locate package xxxx

安装包的源没有添加到/etc/apt/source.list中,导致无法识别安装包,可以自行添加源,也可以使用下面给出的source.list覆盖原来的/etc/apt/source.list文件:

# See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to # newer versions of the distribution. deb http://ports.ubuntu.com/ubuntu-ports/ xenial main restricted deb-src http://ports.ubuntu.com/ubuntu-ports/ xenial main restricted ## Major bug fix updates produced after the final release of the ## distribution. deb http://ports.ubuntu.com/ubuntu-ports/ xenial-updates main restricted deb-src http://ports.ubuntu.com/ubuntu-ports/ xenial-updates main restricted ## Uncomment the following two lines to add software from the 'universe' ## repository. ## N.B. software from this repository is ENTIRELY UNSUPPORTED by the Ubuntu ## team.

添加用户及设置密码

添加用户

useradd -s '/bin/bash' -m -G adm,sudo firefly

给用户设置密码:

passwd firefly

给root用户设置密码:

passwd root

修改完自己的根文件系统就可以退出了。

exit
制作根文件系统

制作自己的根文件系统,大小依据自己的根文件系统而定,注意依据temp文件夹的大小来修改count值

mkdir rootfs dd if=/dev/zero of=linuxroot.img bs=1M count=4000 mkfs.ext4 linuxroot.img sudo mount linuxroot.img rootfs/ sudo cp -rfp temp/* rootfs/ sudo umount rootfs/ e2fsck -p -f linuxroot.img resize2fs -M linuxroot.img

这样 linuxroot.img 就是最终的根文件系统映像文件了。

FAQs
根文件系统加载后,大小不正常,未占满整个分区:

在系统正确加载后执行扩展文件系统命令:

resize2fs /dev/mmcblk1p6 --> rootfs 分区 查看 parameter文件中,root= 节点设备
