First and for most I googled a lot and Its been a week of searching with no solution at all. Please bare with me!
I tried to add all necessary info! Please request more If you need.
My problem is:
I am trying to debug a STM32 bluepill board with skeleton code project using STM32-for-vscode, OpenOCD and cortex debug in Vscode but without any success. The debugging session fails!
My environment is:
1- Mac OS Big Sur version 11.1 (20C69).
2- VSCODE.
3- Cortex Debug Plugin.
4- STM32-for-Vscode plugin.
5- ARM plugin.
6- The project is a Skeleton code created using STM32CubeMax as per STM32-for-Vscode instructions.
7- Brew "Opened --HEAD" version which should work with Cortex debug plugin.
8- Using a STM32f103c8 bluepill flashed with STlink V2.1 firmware as a STlink dongle. I already edited the .cfg file to allow for non genuine STM32 CPU IDs.
9- Using stm32f103c8 bluepill as Target board to upload Code and Debug.
Please note that the exact same Hardware set works perfectly with PlatformIO and flashes and debugs correctly.

and in **Output ** I get:
Info : dropped 'gdb' connection shutdown command invoked Then the debugger controls buttons are grayed out! and my MCU is bricked and I would need to Erase it using a UART connection to get it back to work!
What to do? How to be able to program and debug this board using my environment!
