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bianbu linux裁剪，集成factorytest应用。

该系统通常运行在sdcard上。

编译

$ cd /path/to/bianbu-linux
$ make envconfig           
Available configs in buildroot-ext/configs/:
  1. spacemit_k1_defconfig
  2. spacemit_k1_minimal_defconfig
  3. spacemit_k1_plt_defconfig


your choice (1-3): 

选择3，然后回车即开始编译。

编译完成，可以看到：

其中bianbu-linux-k1_plt.zip适用于Titan Flasher，或者解压后用fastboot刷机；bianbu-linux-k1_plt-sdcard.img为sdcard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

已支持板型：

• deb1

产测工具的系统通常不直接使用板型在u-boot和内核的dts，而是基于它定制。

添加新板型的步骤：

1. 拷贝u-boot的dts到buildroot-ext/board/spacemit/k1/plt_dts/u-boot，例如k1-x_deb2.dts

2. 定制

3. 拷贝内核的dts到buildroot-ext/board/spacemit/k1/plt_dts/kernel，例如k1-x_deb2.dts

4. 修改dtsi路径

   -#include "k1-x.dtsi"
   -#include "k1-x_pinctrl.dtsi"
   -#include "lcd/lcd_gx09inx101_mipi.dtsi"
   -#include "k1-x-hdmi.dtsi"
   -#include "k1-x-lcd.dtsi"
   -#include "k1-x-camera-sdk.dtsi"
   +#include "spacemit/k1-x.dtsi"
   +#include "spacemit/k1-x_pinctrl.dtsi"
   +#include "spacemit/lcd/lcd_gx09inx101_mipi.dtsi"
   +#include "spacemit/k1-x-hdmi.dtsi"
   +#include "spacemit/k1-x-lcd.dtsi"
   +#include "spacemit/k1-x-camera-sdk.dtsi"

5. 修改其他配置

6. 修改output/k1_plt/.config，添加新板型的dts

   -BR2_LINUX_KERNEL_INTREE_DTS_NAME="k1-x_deb1"
   -BR2_LINUX_KERNEL_CUSTOM_DTS_PATH="$(BR2_EXTERNAL_Bianbu_PATH)/board/spacemit/k1/plt_dts/kernel/k1-x_deb1.dts"
   -BR2_TARGET_UBOOT_CUSTOM_DTS_PATH="$(BR2_EXTERNAL_Bianbu_PATH)/board/spacemit/k1/plt_dts/u-boot/k1-x_deb1.dts"
   +BR2_LINUX_KERNEL_INTREE_DTS_NAME="k1-x_deb1 k1-x_deb2"
   +BR2_LINUX_KERNEL_CUSTOM_DTS_PATH="$(BR2_EXTERNAL_Bianbu_PATH)/board/spacemit/k1/plt_dts/kernel/k1-x_deb1.dts $(BR2_EXTERNAL_Bianbu_PATH)/board/spacemit/k1/plt_dts/kernel/k1-x_deb2.dts"
   +BR2_TARGET_UBOOT_CUSTOM_DTS_PATH="$(BR2_EXTERNAL_Bianbu_PATH)/board/spacemit/k1/plt_dts/u-boot/k1-x_deb1.dts $(BR2_EXTERNAL_Bianbu_PATH)/board/spacemit/k1/plt_dts/u-boot/k1-x_deb2.dts"

7. 重新编译u-boot、内核和固件即可

   make uboot-rebuild
   make linux-rebuild
   make

8. 保存配置

   make savedefconfig

定制rootfs

通过buildroot-ext/board/spacemit/k1/plt_overlay定制rootfs，该目录下的文件会在制作镜像前拷贝到output/k1_plt/target目录。
