8.1. 微服务器定制化软件包

在微服务器[SE5/SE7]上执行系统打包脚本

1. 下载打包需要使用的脚本： socBak.sh 。

# and directories in the context of repackaging mode.

cat $TGZ_FILES_PATH/$PARTITION_FILE

2. 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

3. 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。

4. 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/

5. 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一下几个文件

└── socrepack
    ├── boot.tgz
    ├── data.tgz
    ├── opt.tgz
    ├── partition32G.xml
    ├── recovery.tgz
    └── rootfs.tgz

在X86机器上制作定制的系统包, 推荐使用Ubuntu18.04

1. 下载重打包所需文件：

• bootloader-arm64。

• linux-arm64。

• 工具链及Ubuntu基础环境。

• sdcard.tgz: 微服务器原始卡刷包。

注解

工具链及Ubuntu基础环境包的目录解压后如下:

├── distro
├── gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu.tar.xz
└── memory_layout_modification_tool

2. 将distro放到bootloader-arm64同级目录, 将gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu.tar.xz解压到bootloader-arm64同级目录； 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
├── gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu
├── install
│   └── soc_bm1684
│       └── sdcard.tgz
└── distro

3. 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

4. 设置环境变量。

source bootloader-arm64/scripts/envsetup.sh

5. 使用revert_package命令进行拆包。

revert_package

6. 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

7. 将微服务器上生成的文件替换到install/soc_bm1684目录下。

8. 将微服务器上生成的partition32G.xml替换到bootloader-arm64/scripts/目录下。

9. 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。
