在CubeIDE 1.9.0中使用stm32f429i-disco设备工作出错是何原因及如何修复呢？

问答对人有帮助，内容完整，我也想知道答案 0 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 Instruction 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？ /* USER CODE BEGIN Header / /* ****************************************************************************** * @file : main.c * @brief : Main program body ****************************************************************************** * @attention * * Copyright (c) 2022 STMicroelectronics. * All rights reserved. * * This software is licensed under terms that can be found in the LICENSE file * in the root directory of this software component. * If no LICENSE file comes with this software, it is provided AS-IS. * ****************************************************************************** / / USER CODE END Header / / Includes ------------------------------------------------------------------/ #include "main.h" / Private includes ----------------------------------------------------------/ / USER CODE BEGIN Includes / / USER CODE END Includes / / Private typedef -----------------------------------------------------------/ / USER CODE BEGIN PTD / / USER CODE END PTD / / Private define ------------------------------------------------------------/ / USER CODE BEGIN PD / / USER CODE END PD / / Private macro -------------------------------------------------------------/ / USER CODE BEGIN PM / / USER CODE END PM / / Private variables ---------------------------------------------------------/ / USER CODE BEGIN PV / / USER CODE END PV / / Private function prototypes -----------------------------------------------/ void SystemClock_Config(void);
