你好。我在 CubeIDE 1.9.0 中使用
STM32f429i-disco 设备工作。问题出现在固件和调试方面。我做了一个简单的例子来检查。在调试期间,在执行 HAL_Delay(第 95 行)时注意到奇怪的行为。在此行执行 Step Over 时,Debug Current Instruc
tion Pointer 保持在同一行。如果您在此行上放置一个断点并恢复,则 LED 会在每次迭代后重置为初始状态(关闭),尽管它们应该每 250 毫秒更改一次状态。以前,我在这个板上使用引导加载程序。我还注意到,在微控制器内存中没有固件的情况下通电时,用户 USB LED 会亮起。Keil 面临与上述相同的问题。请告诉我,这可能是
电路板机械损坏的结果,还是其他原因以及如何修复?
