mido设备移植Ubuntu20.04
一、初始化环境
1.安装编译依赖环境
#这里宿主机使用Ubuntu20.04系统
sudo apt install binfmt-support qemu-user-static gcc-10-aarch64-linux-gnu kernel-package fakeroot simg2img img2simg mkbootimg bison flex gcc-aarch64-linux-gnu pkg-config libncurses-dev libssl-dev unzip git debootstrap
2.下载最新内核源码
mkdir workspaces && cd workspaces
git clone https://github.com/msm8953-mainline/linux.git --depth 1
(可选)设置git代理使用科学的网络:
cat > gitproxy.sh << EOF
#!/bin/bash
case \$1 in
on)
git config --global http.proxy 'http://192.168.2.64:7897'
git config --global https.proxy 'http://192.168.2.64:7897'
;;
off)
git config --global --unset http.proxy
git config --global --unset https.proxy
;;
status)
git config --get http.proxy
git config --get https.proxy
;;
esac
EOF
chmod +x gitproxy.sh
3.下载内核编译.config文件
参考大佬仓库的.config文件https://gitee.com/meiziyang2023/ubuntu-ports-xiaomi-625-phones
或者pmos的config-postmarketos-qcom-msm8953.aarch64文件https://gitlab.com/postmarketOS/pmaports/-/tree/master/device/community/linux-postmarketos-qcom-msm8953
cd cd ~/workspaces/linux
wget https://gitee.com/meiziyang2023/ubuntu-ports-xiaomi-625-phones/raw/master/.config
二、编译内核和内核deb安装包
1.设置编译环境变量
cd ~/workspaces
cat > env.sh << EOF
export CROSS_COMPILE=aarch64-linux-gnu-
export ARCH=arm64
export CC=aarch64-linux-gnu-gcc
EOF
chmod +x env.sh
2.开始编译内核
source ./env.sh
cd ./linux
make clean
rm -r ./debian
make menuconfig
make -j$(nproc)
3.编译内核deb安装包
fakeroot make-kpkg --initrd --cross-compile aarch64-linux-gnu- --arch arm64 kernel_image kernel_headers -j$(nproc)
#编译完成,内核安装包生成在源码上级目录
三、制作rootfs.img镜像
1.创建空白rootfs.img镜像文件
cd ~/workspaces
dd if=/dev/zero of=rootfs-focal.img bs=1G count=2
mkfs.ext4 rootfs-focal.img
2.使用debootstrap
mkdir ~/chroot
sudo mount rootfs-focal.img ~/chroot
sudo debootstrap --arch arm64 focal ~/chroot https://mirrors.aliyun.com/ubuntu-ports
#sudo debootstrap --arch arm64 --variant=minbase --include=vim,ca-certificates,apt-utils,locales focal ~/chroot https://mirrors.aliyun.com/ubuntu-ports
3.chroot进入rootfs安装喜欢的包,初始化一些配置
sudo mount --bind /proc ~/chroot/proc
sudo mount --bind /dev ~/chroot/dev
sudo mount --bind /dev/pts ~/chroot/dev/pts
sudo mount --bind /sys ~/chroot/sys
sudo chroot ~/chroot
#以下命令即都是在chroot环境中
#修改阿里源
cat > /etc/apt/sources.list << EOF
deb https://mirrors.aliyun.com/ubuntu-ports/ focal main restricted universe multiverse
deb-src https://mirrors.aliyun.com/ubuntu-ports/ focal main restricted universe multiverse
deb https://mirrors.aliyun.com/ubuntu-ports/ focal-security main restricted universe multiverse
deb-src https://mirrors.aliyun.com/ubuntu-ports/ focal-security main restricted universe multiverse
deb https://mirrors.aliyun.com/ubuntu-ports/ focal-updates main restricted universe multiverse
deb-src https://mirrors.aliyun.com/ubuntu-ports/ focal-updates main restricted universe multiverse
# deb https://mirrors.aliyun.com/ubuntu-ports/ focal-proposed main restricted universe multiverse
# deb-src https://mirrors.aliyun.com/ubuntu-ports/ focal-proposed main restricted universe multiverse
deb https://mirrors.aliyun.com/ubuntu-ports/ focal-backports main restricted universe multiverse
deb-src https://mirrors.aliyun.com/ubuntu-ports/ focal-backports main restricted universe multiverse
EOF
#更新源
apt update && apt upgrade
#设置locales
locale-gen en_US.UTF-8
locale-gen zh_CN.UTF-8
update-locale LANG=en_US.UTF-8
#设置中国时区
rm /etc/localtime
ln -s /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
#设置hostname
echo 'xiaomi-mido' > /etc/hostname
#卸载netplan
apt purge netplan.io
#创建用户
useradd -m -s /bin/bash hol
usermod -aG sudo hol
#设置密码
passwd hol
#安装一些包
apt install man man-db bash-completion vim tmux network-manager chrony openssh-server initramfs-tools --no-install-recommends -y
4.安装编译的内核
在宿主机中执行拷贝内核安装包到rootfs中
cp ~/workspaces/linux*.deb ~/chroot/tmp
在chroot环境中执行安装内核,安装之前确保chroot环境中已经安装了initramfs-tools
cd /tmp
dpkg --get-selections | grep linux
dpkg -l | grep -E "linux-headers|linux-image" |awk '{print $2}'|xargs dpkg -P
rm -rf /lib/modules/*
dpkg -i linux*.deb
dpkg --get-selections | grep linux
ls /lib/modules
5.拷贝firmware文件
在宿主机中执行拷贝firmware到rootfs中,firmwar文件来自https://github.com/Kiciuk/proprietary_firmware_mido
cd ~/workspaces
git clone https://github.com/Kiciuk/proprietary_firmware_mido.git
cp -r ./proprietary_firmware_mido/apnhlos/* ~/chroot/usr/lib/firmware/
cp -r ./proprietary_firmware_mido/firmware/* ~/chroot/usr/lib/firmware/
cp -r ./proprietary_firmware_mido/modem/* ~/chroot/usr/lib/firmware/
在chroot环境中执行
cd /usr/lib/firmware/
ldconfig
6.制作boot.img
在宿主机中执行
mkdir ~/workspaces/tmp_mkboot
rm -rf ~/workspaces/tmp_mkboot/*
cp ~/workspaces/linux/arch/arm64/boot/dts/qcom/*mido*.dtb ~/workspaces/tmp_mkboot/
cp ~/workspaces/linux/arch/arm64/boot/Image.gz ~/workspaces/tmp_mkboot/
cp ~/chroot/boot/initrd* ~/workspaces/tmp_mkboot/
cp ~/workspaces/tmp_mkboot/initrd* ~/workspaces/tmp_mkboot/initrd.img
cp ~/workspaces/tmp_mkboot/msm*.dtb ~/workspaces/tmp_mkboot/dtb
cat ~/workspaces/tmp_mkboot/Image.gz ~/workspaces/tmp_mkboot/dtb > ~/workspaces/tmp_mkboot/kernel-dtb
mkbootimg --base 0x80000000 \
--kernel_offset 0x00008000 \
--ramdisk_offset 0x01000000 \
--tags_offset 0x00000100 \
--pagesize 2048 \
--second_offset 0x00f00000 \
--ramdisk ~/workspaces/tmp_mkboot/initrd.img \
--cmdline "console=tty0 root=UUID=20336aa9-c9de-431a-b679-dcf10065c121 rw loglevel=3 splash"\
--kernel ~/workspaces/tmp_mkboot/kernel-dtb -o ~/workspaces/tmp_mkboot/boot.img
#这里的UUID需要替换成自己的rootfs.img的uuid,通过file查看,格式化后的rootfs.img的uuid不会变。
file ~/workspaces/rootfs-focal.img
#其他偏移量可以在pmos网站的deviceinfo上找到
7.一些优化
自动扩展文件系统
cat > /etc/systemd/system/resizefs.service << 'EOF'
[Unit]
Description=Expand root filesystem to fill partition
After=local-fs.target
[Service]
Type=oneshot
ExecStart=/usr/bin/bash -c 'exec /usr/sbin/resize2fs $(findmnt -nvo SOURCE /)'
ExecStartPost=/usr/bin/systemctl disable resizefs.service
RemainAfterExit=true
[Install]
WantedBy=default.target
EOF
systemctl enable resizefs.service
开启串口登录
cat > /etc/systemd/system/[email protected] << EOF
[Unit]
Description=Serial Console Service on ttyGS0
[Service]
ExecStart=-/usr/sbin/agetty -L 115200 ttyGS0 xterm+256color
Type=idle
Restart=always
RestartSec=0
[Install]
WantedBy=multi-user.target
EOF
systemctl enable [email protected]
#如果串口登录失效,可能是g_serial模块没有加载
echo g_serial >> /etc/modules
8.清理chroot环境,并退出
在chroot环境中执行
apt clean
rm -f /tmp/*
history -c
Ctrl + D
9.卸载rootfs镜像挂载,转换成刷机镜像
在宿主机中执行
sudo umount ~/chroot/proc
sudo umount ~/chroot/dev/pts
sudo umount ~/chroot/dev
sudo umount ~/chroot/sys
sudo umount ~/chroot
img2simg ~/workspaces/rootfs-focal.img ~/workspaces/tmp_mkboot/rootfs.img
这样在~/workspaces/tmp_mkboot目录中就得到了可以刷机的rootfs.img和boot.img了。可以愉快的去刷机了:)
