DF723(FT2000+) DF716(FT2000/4)基于grub2.05、openEuler 20.03内核、busybox1.32.1源码制作最小系统U盘

settings->Build Options选中Build staitc binary。格式化U盘，一个vfat小分区用于efi，一个ext4大分区用于存放根文件系统。双击Esc按键退回到主菜单，再次双击，保存退出。重新执行grub-install覆盖安装。登录查看详细信息(登录密码参考。劣质3.1U盘，更换U盘。解压busybox源码。编译grub2.06。安装grub到usb。

编译grub2.06

sudo apt install -y bison flex
./configure --prefix=/usr/local
make -j4
sudo make install

安装grub到usb

sudo apt install -y efibootmgr

sudo mkdir /mnt/efi
sudo mount /dev/sdb1 /mnt/efi
sudo mkdir /mnt/efi/boot
sudo /usr/local/sbin/grub-install --efi-directory=/mnt/efi --boot-directory=/mnt/efi/boot /dev/sdb --removable

busybox做sysroot根文件系统

编译busybox

wget https://busybox.net/downloads/busybox-1.32.1.tar.bz2

安装依赖工具

yum install -y tar ncurses-devel

解压busybox源码

tar -xvf busybox-1.32.1.tar.bz2

生成配置文件

make menuconfig

settings->Build Options选中Build staitc binary

双击Esc按键退回到主菜单，再次双击，保存退出

编译

make -j64

查看编译输出

生成系统目录

make install

生成sysroot

#!/bin/bash
set -x
workdir=$(pwd)
mkdir sysroot
rsync -avr -P res/* sysroot/
rsync -av -P src/linux-4.19.90-2112.8.0.0131.oe1.aarch64/arch/arm64/boot/Image.gz sysroot/boot/vmlinuz-4.19.90

        ln -svf bin/busybox init
        ln -svf usr/lib lib
        ln -svf usr/lib64 lib64
)

文件同步到U盘

rsync -avr --delete -P  sysroot/* /media/yeqiang/c788260c-05f3-48e6-a9b6-23c9f2375cfa/
cp -f res/boot/efi/boot/grub/grub.cfg /media/yeqiang/2ACD-883D/boot/grub/grub.cfg
