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：
-
拷贝u-boot的dts到
buildroot-ext/board/spacemit/k1/plt_dts/u-boot，例如k1-x_deb2.dts -
定制
-
拷贝内核的dts到
buildroot-ext/board/spacemit/k1/plt_dts/kernel，例如k1-x_deb2.dts -
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" -
修改其他配置
-
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" -
重新编译u-boot、内核和固件即可
make uboot-rebuild
make linux-rebuild
make -
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。
