测试指南

测试环境

硬件

• D12x 开发板
• Host 端的板子（D21x 开发板可满足大部分测试的格式需求）
• 跨接两个板子的子板、或者数据排线

软件

• MDI 模块的测试 demo：test_mdi
• PC 端的串口终端软件，用于 PC 和开发板进行串口通信

软件配置

test_mdi 配置

在 Luban-Lite 根目录下执行 scons --menuconfig，进入 menuconfig 的功能配置界面，按如下选择：

Drivers options  --->
    Drivers examples  --->
        [*] Enable MDI driver test command

test_mdi 测试

test_mdi 启动 MDI，接收 Host 端传来的数据和命令，并将数据传给 GE、DE 模块去处理和显示。

在打开 test_mdi 的编译后，板子上可直接运行 test_mdi 命令：

aic /> test_mdi -h
Compile time: Feb 29 2024 16:16:41
Usage: test_mdi [options]:
     -c, --count        the number of capture frame
     -h, --help

Example: test_mdi -c 1
