8.1. 微服务器定制化软件包
8.1.1. 第一步：在微服务器[SE5/SE7]上执行系统打包脚本

sync
准备一个外部存储设备（SD卡，TF卡或U盘等），将打包工具 socBak.sh 拷入该设备下, 将设备插到微服务上, 切换到root账户。
sudo su
登录到微服务器上，使用 fdisk -l 指令查看刚才接入的外部存储的设备文件名，外部存储设备接入盒子后，系统会自动分配一个设备文件名。
fdisk -l
注解
测试使用的设备在微服务上显示的是 /dev/sda4, 后面操作是在此基础上进行的，不同的设备显示可能不同。
在根目录下创建 socrepack 目录，将外部存储挂载到该目录下。
cd /
mkdir socrepack
cd socrepack/
mount /dev/sda4 /socrepack/
给脚本添加执行权限, 然后执行打包脚本。
chmod +x socBak.sh
bash socBak.sh
执行成功后主要生成以下几个文件
└── socrepack
├── boot.tgz
├── data.tgz
├── fip.bin
├── opt.tgz
├── partition32G.xml
├── recovery.tgz
├── spi_flash.bin
├── spi_flash_bm1684(x).bin
└── rootfs.tgz
8.1.2. 第二步：在X86机器上制作定制的系统包
注解
X86机器推荐使用Ubuntu18.04系统。
下载重打包所需文件：
sdcard.tgz: 微服务器原始卡刷包。
在bootloader-arm64同级目录下创建install目录, 并在install目录下创建soc_bm1684目录；将sdcard.tgz移动到install/soc_bm1684路径下。
注解
最终的目录结构如下:
├── bootloader-arm64
├── install
│ └── soc_bm1684
│ └── sdcard.tgz
安装依赖项。
sudo apt install bison flex bc rsync kmod byobu language-pack-en gcc util-linux exfat-utils dosfstools
sudo apt install cpio uuid-dev cmake libssl-dev fakeroot dpkg-dev uuid libxml2
sudo apt install device-tree-compiler u-boot-tools libxml2-dev debootstrap qemu-user-static kpartx
设置环境变量。
source bootloader-arm64/scripts/envsetup.sh
使用revert_package命令进行拆包。
revert_package
拆包结果会在install/soc_bm1684路径，软件包和文件夹的具体描述请参考《 官方BSP文档 》。
注解
其目录结构如下:
└── soc_bm1684
├── boot.tgz
├── package_update
├── rootfs.tgz
├── sdcard.tgz
├── spi_flash_bm1684.bin
├── data.tgz
├── opt.tgz
├── recovery.tgz
├── rootfs_rw.tgz
├── spi_flash.bin
└── spi_flash_bm1684x.bin
将微服务器上生成的文件替换到install/soc_bm1684目录下。
将微服务器上生成的partition32G.xml替换到bootloader-arm64/scripts/目录下。
使用build_update sdcard指令更新刷机包，得到的定制刷机包位于install/soc_bm1684/sdcard目录下。
