基于RT1052 Aworks SDRAM压力测试（十七）

本文主要是通过迁移的思维，记录本人初次使用周立功的Aworks框架进行BSP开发

本文主要讲述在RT1052上面，使用i.mxrt-dram-tool-v0.2工具进行压测试。

1. 原理

i.mxrt-dram-tool-v0.2工具其实是集成memtester工具对SDRAM进行压力测试。

2. 操作过程

1)MCU进入烧录serial download模式

2)接上串口，接上USB线

3)打工工具配置界面，打开串口和USB烧录线，选择对应硬件平台测试脚本，选择MCU工作时钟，点击运行即可。

4）测试结果

RT DRAM Tool V0.2 build on Mar 15 2019 17:48:43

  - Start Address(Hex): The memory address test starts from, the default is base address.
  - Test Size: No more than the total memory space, the default is total size.
  - Test Freq(MHz): DRAM frequency.
  - Loop Number: Stress testing loop number. '0' means limitless!

3. 总结

如果一开始就知道有这个工具的话会在调试第一版的硬件板本时使用。有可以在做高低温测试时，使用该工具测试板子的稳定性。
