Probably a dumb question/answer ('cause I don’t have any debuggers that work with PlatformIO, so havn’t used it)… did you go into the debug section of VSCode?


Try F5 in VSCode. It works for me with my STM32F4DISCOVERY. Debugger starts and pauses on temporary breakpoint, typically on first statement in main()
