VSCode调试Raspberry Pi Pico时OpenOCD意外退出问题求助

问题背景 #

我正尝试使用Picoprobe在VSCode中调试Raspberry Pi Pico。已在MSYS2 Mingw64 Shell中编译OpenOCD并能正常运行所有调试流程，但在VSCode中调试时弹出提示OpenOCD: GDB Server Quit Unexpectedly。

调试控制台输出 #

疑问与求助 #

• 我的配置是否存在错误？
• 猜测原因：部分依赖仅在MSYS2 Mingw64环境中满足，VSCode运行GDB/OpenOCD时可能未使用该环境（比如用了Windows PowerShell），如何强制VSCode或Cortex-Debug扩展使用MSYS2 Mingw64 Shell运行OpenOCD？
• 另一种方案：在MSYS2 Mingw64中手动启动OpenOCD服务器，再让VSCode连接到该服务器，是否可行？具体如何配置？目前只找到VSCode同时启动GDB和OpenOCD的方案。
