I have used platform to compile stm32f103 program in SPL frameworks,and it show I have uploaded successfully with JLINK,but it does not run to main function ,I think there are something wrong where i configure the debug,I want to know how to configure the debug,and use what tools to debug,GDB?
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()
