问题描述
首先，对于大多数人来说，我用谷歌搜索了很多，搜索了一周，根本没有解决方案。请和我一起裸体！
我尝试添加所有必要的信息！如果您需要，请请求更多。
我的问题是：
我正在尝试使用 STM32-for-vscode、OpenOCD 和 Cortex 调试在 Vscode 中调试带有骨架代码项目的 STM32 bluepill 板，但没有任何成功。调试会话失败！
我的环境是：
1- Mac OS Big Sur 版本 11.1 (20C69)。
2- VSCODE。
3- Cortex 调试插件。
4- STM32-for-Vscode 插件。
5- ARM 插件。
6- 该项目是根据 STM32-for-Vscode 指令使用 STM32CubeMax 创建的骨架代码。
7- Brew "Opened --HEAD" 版本应该与 Cortex 调试插件一起使用。
8- 使用带有 STlink V2.1 固件的 STM32f103c8 bluepill 作为 STlink 加密狗。我已经编辑了 .cfg 文件以允许使用非正版 STM32 cpu ID。
9- 使用 stm32f103c8 bluepill 作为目标板上传代码和调试。
请注意完全相同的硬件集与 PlatformIO 完美配合，并且可以正确刷新和调试。

当我开始调试时，我在 movs r1,#0 上的 启动文件 中获得了代码控制
使用以下调试器控件：

Cannot insert hardware breakpoint 1.

虽然，我根本没有设置任何断点！
在 **Output ** 我得到：
Info : dropped 'gdb' connection
shutdown command invoked
然后调试器控件按钮变灰了！我的 MCU 变砖了，我需要使用 UART 连接擦除它才能让它恢复工作！
怎么办？如何能够使用我的环境对该板进行编程和调试！
