我目前正在开发基于 stm32f103C8 的 pcb。当前项目状态可以在这个GitHub 项目中查看。

我面临的问题是我无法在不调试设备的情况下运行代码。我的问题是：我该怎么做才能使代码在没有调试器的情况下运行？

设置

印刷电路板

我使用下面的Schematic。目前未填充电池管理和外部时钟。所以我使用内部振荡器。我通过由稳压器调节的 5V 电源为设备供电。

编程

我使用带有 SWD 的 st-link v2。只连接了 swclk、swdio 和 gnd。为了开发应用程序代码，我使用 cubemx（ide 和代码生成器）。

我测试过的

  • 当从 GND 断开 Boot0 和 Boot1 时，我可以使用调试器正常运行代码
  • 当将 Boot0 和 Boot1 连接到 GND 时，调试器直接跳转到 HardFault_Handler
  • 当没有调试器连接到 Boot0 和 Boot1 时，代码永远不会运行。
  • 电压水平稳定
  • 使用电源循环和 NRST 复位 MCU 时的行为没有区别。

boot0 连接到 GND 就足够了。只有当 boot0 为高电平时，Boot1 才有意义。

复位后的即时硬故障通常表示初始堆栈地址无效（向量表中的偏移量 0）

如果您有正确的链接描述文件，请检查链接描述文件。

如果您使用 atollic studio 或 STM32CUBE IDE，您可以使用硬故障插件 - 这为您完成了所有艰巨的工作（从堆栈中获取内容并读取相应的系统寄存器）
