需要寻求帮助，我使用STM32H563VIT6配置了一个引脚输出高低电平，在debug模式下可以运行，在正常运行（release）下就不能得到结果，这是为什么？而且我是在HSE不行还用了HSI也不行

Translation:

I need help. I used STM32H563VIT6 to configure a pin to output high and low levels. It works in debug mode, but not in normal operation (release). Why? And I used HSI but it didn't work in HSE.

    So what, exactly, happens in Release ?

    If it works in Debug, then your hardware must be OK - so the problem must be somewhere in your software.

    Maybe it's crashing before it gets to toggling the pin?

    Try to create a minimum but complete project which illustrates the issue.

    What, exactly, do you mean by that?

    A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.
