嵌入式实操----基于RT1170 移植memtester做SDRAM测试（二十五）
2022-08-05 08:36:00 【嵌入式实操】
本文主要是通过迁移的思维，记录本人初次使用NXP MCUXpresso SDK API进行BSP开发
1. 移植来源
reference:
https://blog.51cto.com/henjay724/2711883
https://github.com/JayHeng/cortex-m-apps
由于RT1170上面没有SDRAM的压力测试工具，所以通过移植memtester工程至SoC,用于SDRAM的测量。
2. 应用
复制memtester目前至工程
将相关文件添加入工程当中
将添加相关的头文件路径：
增加相关的测试代码如下：
diff --git a/SDK_2.8.0_MIMXRT1170-EAR3/boards/easyarm-rt1170-revb/driver_examples/gpio_bootloader/led_output/cm7/gpio_led_output.c b/SDK_2.8.0_MIMXRT1170-EAR3/boards/easyarm-rt1170-revb/driver_examples/gpio_bootloader/led_output/cm7/gpio_led_output.c

3. 总结
有比较过memtester 4.5.1与参考移植版本memtester 4.5.0 相关文件之间的区别
- 主要是printf函数的移植。
- 主要是注掉跨平台代码的判断。
- 去除一些flush exit等函数。
- 找到对应的main入口函数，重写mian函数，并增加相关的参数memtester_main。
希望对各位读者帮助。
