Trying to in-circuit debug BluePill program in VSCode 1.76.2 with PlatformIO

[Piter_de_Vries]

I want to do in-circuit debugging of my BluePill program with an STLink v2 dongle in VSCode but I don't think it's working. I can't enter debugging mode unless Boot 0 is set to 1. If Boot 0 is set to 0, then I get this error when I click on Start Debugging:

"Failed to launch GDB: .pioinit:13: Error in sourced command file: Remote communication error. Target disconnected.: Success. (from interpreter-exec console “source .pioinit”)".



If I set Boot 0 to 1 and click on Start Debugging, then it appears that the code compiles, uploads and enters debugging mode but the variables I'm watching don't seem to change. To check, I added a counter which is meant to increment every time the main loop finishes but value seems to start at 64 and stay there.

Also, when debugging starts, VScode opens this file: C:\Users\piter\.platformio\packages\framework-arduinoststm32\variants\STM32F1xx\F103C8T_F103CB(T-U)\startup_M200_f103xb.S



I posted the entirety of my program here: https://pastebin.com/U0UXywP2

I'd appreciate any insight into what's going wrong for me. Thanks in advance.
