流程

1. 设置导出环境变量

2. make-targets | make-usage 参数的执行分支

3. 创建输出目录，软连接redme等

4. 获取支持的命令

   1. CMDS="$(run_build_hooks support-cmds all | xargs)"
      通过调用run_build_hooks 并传入参数support-cmds all 最后输出通过xargs处理，赋值给CMDS
      这个字符串包含了所有支持的命令或选项。
      

5. 遍历选项

   1. help | h | -h | --help | usage 等调用 usage 输出帮助
   2. shell | cleanall：如果选项是shell或cleanall，则执行一段检查代码，确保这些选项不是与其他选项组合使用的。如果是单独使用（即$opt等于$OPTIONS），则跳出循环；否则，显示错误信息。
   3. post-rootfs：如果选项是post-rootfs，则检查它是否是第一个选项，并且后面跟着一个目录参数。如果是，将OPTIONS设置为post-rootfs并跳出循环；否则，显示错误信息。
   4. *：对于所有其他选项，使用option_check函数检查它们是否在$CMDS中定义的支持命令列表中。如果是，则继续循环；否则，显示错误信息。

6. 日志相关

7. 初始化

8. 加载配置环境变量等

9. 设置环境变量，处理特殊命令等

10. 输出显示最终配置信息

11. 开始构建，最终进入run_build_hooks 传入参数 build debian

    1. 

12. run_build_hooks 函数

    1. 匹配分支 init | pre-build | make-* | usage | support-cmds
    2. 日志记录
    3. 调用 run_hooks device/rockchip/common/build-hook debian

13. run_hooks

    1. 调用device/rockchip/common/build-hook 下面的sh文件

30-rootfs.sh

流程

1. 进行文件系统构建，安装库，等

#echo 'export LD_LIBRARY_PATH=$QT_ROOT/lib:$QT_ROOT/plugins/platforms' | sudo tee -a $QT5SH_PATH

流程

1. cp 跟文件系统的库，制作交叉编译环境
2. 制作交叉编译，配置文件
3. 配置，编译qt，并cp到跟文件系统

mk-image.sh

源码

#!/bin/bash -e

TARGET_ROOTFS_DIR=./binary
ROOTFSIMAGE=linaro-rootfs.img
EXTRA_SIZE_MB=300
IMAGE_SIZE_MB=$(( $(sudo du -sh -m ${TARGET_ROOTFS_DIR} | cut -f1) + ${EXTRA_SIZE_MB} ))


echo Making rootfs!

if [ -e ${ROOTFSIMAGE} ]; then
	rm ${ROOTFSIMAGE}
fi

for script in ./post-build.sh ../device/rockchip/common/post-build.sh; do
	[ -x $script ] || continue
	sudo $script "$(realpath "$TARGET_ROOTFS_DIR")"
done

dd if=/dev/zero of=${ROOTFSIMAGE} bs=1M count=0 seek=${IMAGE_SIZE_MB}

sudo mkfs.ext4 -d ${TARGET_ROOTFS_DIR} ${ROOTFSIMAGE}

echo Rootfs Image: ${ROOTFSIMAGE}

流程

1. 运行2个 post-build.sh
2. 制作打包跟文件系统

post-build.sh

后续的配置信息

1. 文件系统的挂载信息修改添加
2. 执行 device/rockchip/common/post-hooks 下的sh，启动一些服务？
   1. 02-usb.sh
   2. 05-udev.sh
   3. 06-async-commit.sh
   4. 10-os-release.sh
   5. 20-info.sh
   6. 30-fstab.sh
   7. 40-busybox-reboot.sh
   8. 50-locale.sh
   9. 60-dirs.sh
   10. 90-overlay.sh
   11. 95-partitions.sh
   12. 99-owner.sh

大致流程

1. 编译安装必要库drm，npu等
   1. 进入文件系统，然后gtp命令安装
2. 然后cp ln等，qt编译安装
3. 文件系统制作

系统制作步骤

1. 解压 debian，原始根文件系统

   sudo tar -xpf linaro-bullseye-alip-20240903-1.tar.gz 
   

2. 获取文件系统大小，然后+300

   sudo du -sh -m ./binary | cut -f1
   

3. 创建文件

   dd if=/dev/zero of=linaro-rootfsxw.img bs=1M count=0 seek=2385
   

4. 写入内容并格式化ext4

   sudo mkfs.ext4 -d ./binary linaro-rootfsxw.img
