【RK3399】2.制作ubuntu20.04 roomfs

firefly自带的文件系统由于缺少一些基本功能模块因此我们可以自己手动制作一个ubuntu20.04的文件系统。

下载Ubuntu根文件系统

http://cdimage.ubuntu.com/ubuntu-base/releases/

安装虚拟机

apt-get install qemu-user-static

解压

mkdir ubuntu-rootfs
tar -xpf ubuntu-base-20.04.5-base-arm64.tar.gz  -C ubuntu-rootfs

复制一下虚拟机的运行环境

cp -b /etc/resolv.conf ubuntu-rootfs/etc/resolv.conf
cp /usr/bin/qemu-aarch64-static ubuntu-rootfs/usr/bin/

复制官方外设驱动文件

将开发板挂载到虚拟机上将开发板的/vendor/system/lib/firmware,这三个文件夹复制到我们自己的文件系统中。

挂载根文件系统

创建ch-mount.sh文件写入以下脚本

#!/bin/bash
# 
function 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
    echo "CHROOT..."
    sudo chroot ${2}
    echo "Success!"
}
function 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
elif [ "$1" == "-u" ] && [ -n "$2" ];
then
    umnt $1 $2
else
    echo ""
    echo "Either 1'st, 2'nd or both parameters were missing"
    echo ""
    echo "1'st parameter can be one of these: -m(mount) OR -u(umount)"
    echo "2'nd parameter is the full path of rootfs directory(with trailing '/')"
    echo ""
    echo "For example: ch-mount -m /media/sdcard/"
    echo ""
    echo 1st parameter : ${1}
    echo 2nd parameter : ${2}
fi

把下载好的脚本置于ubuntu-rootfs目录的上一级目录并修改权限

chmod a+x ch-mount.sh
./ch-mount.sh -m ubuntu-rootfs/

执行mount动作注意退出后一定再执行 ./ch-mount.sh -u ubuntu-rootfs/否则你的本机ubuntu系统会出问题需要重启才能恢复正常。

拷贝bash依赖库

执行挂载脚本时遇到以下错误可以拷贝bash动态库。

➜  tools sudo chroot ubuntu-rootfs 
chroot: failed to run command ‘/bin/zsh’: No such file or directory

查看/bin/bash文件所依赖的动态链接库然后依次拷贝到相应目录。由于我安装了zsh所以除了拷贝bash动态库外还需要拷贝zsh动态库。没有安装zsh的可以不用拷贝zsh动态库。

zhongyi@ubuntu:~$ ldd /bin/zsh
        linux-vdso.so.1 (0x00007ffd5c1dc000)

$cp /bin/bash ubuntu-rootfs/bin
$cp /bin/zsh ubuntu-rootfs/bin

执行挂载

成功挂载后会看到自动切换为root用户。

zhongyi@ubuntu:~/tools$ ./ch-mount.sh -m ubuntu-rootfs/
MOUNTING...
CHROOT...
zsh: failed to load module `zsh/zle': /usr/lib/x86_64-linux-gnu/zsh/5.4.2/zsh/zle.so: cannot open shared object file: No such file or directory     
#已经成功挂载

设置账户名和密码

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

设置主机名

echo 'ubuntu.firefly' > /etc/hostname

添加主机入口到/etc/hosts

127.0.0.1 localhost 
127.0.0.1 ubuntu.firefly
127.0.1.1 firefly 

添加nameserver

vim /etc/resolvconf/resolv.conf.d/head
#添加nameserver
nameserver 114.114.114.114
nameserver 8.8.8.8

取消挂载

exit
./ch-mount.sh -u ubuntu-rootfs/

创建 mkrootfs.sh文件写入以下脚本其中2048取决于你的根文件系统实际大小比如安装了桌面环境后若大小超过2048M就改大一点

#!/bin/bash
# 
dd if=/dev/zero of=ubuntu-rootfs.img bs=1M count=2048
sudo  mkfs.ext4  ubuntu-rootfs.img
rm -r rootfs
mkdir  rootfs
sudo mount ubuntu-rootfs.img rootfs/
sudo cp -rfp ubuntu-rootfs/*  rootfs/
sudo umount rootfs/
e2fsck -p -f ubuntu-rootfs.img
resize2fs  -M ubuntu-rootfs.img

执行制作

➜  tools ./mkrootfs.sh
➜  tools ls -al |grep *.img
-rw-rw-r--  1 zhongyi zhongyi 1497706496 Sep 30 21:32 ubuntu-rootfs.img

烧写镜像

sudo upgrade_tool di -rootfs ubuntu-rootfs.img
