产测工具

本文档介绍产测工具。

简介​

产测工具是一个用于测试板卡或整机硬件接口连通性的系统，基于 Buildroot 裁剪，集成 factorytest 应用。该系统通常运行在 SD 卡上。

$ cd /path/to/buildroot-sdk
$ make envconfig
Available configs in buildroot-sdk/buildroot-ext/configs:
  1. spacemit_k3_ci_defconfig
  2. spacemit_k3_defconfig
  3. spacemit_k3_fpga_defconfig
  4. spacemit_k3_plt_defconfig

Your choice (1-4):

选择4，然后回车即开始编译。

编译完成，可以看到以下输出：

其中：

  • Buildroot-k3_plt.zip 适用于 Titan Flasher，或者解压后用 fastboot 刷机。
  • Buildroot-k3_plt-sdcard.img 为 SD 卡固件，解压后可以用 dd 命令或者 balenaEtcher 写入sdcard。

固件默认用户名：root，密码：bianbu。

定制​

添加板型​

目前产测工具已支持k3 deb1和com260板型，如果要支持新的板型步骤如下：

  1. 增加板型Uboot和内核设备树。

  2. 产测工具源码位于buildroot-sdk/package-src/factorytest目录，针对目标板型修改源码。

  3. 重新编译U-Boot、内核和打包固件：

make uboot-rebuild
make linux-rebuild
make

定制 rootfs​

通过 buildroot-ext/board/spacemit/k3/plt_overlay 定制 rootfs。该目录下的文件会在制作镜像前拷贝到 output/k3_plt/target 目录。
