STM32CubeIDE and OpenOCD: Error: timed out while waiting for target halted

Question

Hardware/IDE 上下文：

Part/board: 正版 STM32F103C8 (BluePill)
程序员：ST-Link V2
IDE: STM32CubeIDE 1.5.1 完全更新 Windows 10
闪烁utility/debugger：OpenOCD

在尝试 build/flash 一个简单的 PC_13 LED 闪烁程序到我的 BluePill 板时，我遇到了来自 OpenOCD 的错误，如下所示：

我有兴趣在我的项目中使用基于 OpenOCD 的闪烁，以利用一些 STM32F103C8 clone boards 我周围的东西，但是当我切换闪烁模式/“调试探针”时，上传过程再次运行在 STM32CubeIDE 中从 ST-Link (OpenOCD).

回到 ST-Link (ST-Link GDB Server)

这对我来说是一个特殊的错误，特别是因为我特别记得这个确切的配置 (STM32CubeIDE + OpenOCD + ST-Link + STM32F103C8 ) 几个月前工作。有没有人知道这可能是由什么引起的？我有 OpenOCD 调试器来使用标准的自动生成的配置文件。

另外，如果您还需要 information/details 帮助诊断此问题，请告诉我。我很乐意提供任何必要的东西。

编辑 2/22/2021：

这是自动生成的（由 STM32CubeIDE）OpenOCD .cfg 文件的副本：

最终，经过进一步的研究和反复试验，我确定了一个似乎对我有用的修复方法。我注意到当停止 CPU 的错误出现时，似乎已经加载了正确的程序并且只需要手动切换 RESET 按钮。这些是我最终确定的 OpenOCD 设置：

默认配置的变化：

SWD 频率：8 → 4 MHz
- 从技术上讲这不是工作所必需的，但 OpenOCD 无论如何都会在上传过程中自动恢复到 4 MHz
重置模式：在重置下连接 → None

这对我有用，输出如下：
