Setup Stm32f103 blue pill under vscode

STM32F103.md

stm32f103 Blue pill C/C++ programming

In STM32CubeMX, enable debugging: Pinout & Configuration > System Core > SYS > Mode > Debug: Enable.

Then under Project Manager > Toolchain/IDE: Makefile

Inside VSCode, add a configuration in launch.json:

        {
            "name": "GDB",
            "type": "gdb",
            "request": "launch",
            "cwd": "${workspaceRoot}",
            "target": "./build/oled_test.elf",
            "gdbpath" : "/usr/bin/gdb-multiarch",
            "autorun": [
                "target remote localhost:3333",
                "monitor reset init",
                "monitor sleep 100",
                "monitor halt",
                "monitor sleep 100",
                "load",
                "break main",
                "continue",
                ]
        }

Flash your program:

st-flash write build/oled_test.bin 0x8000000

or use STM32 official flash programmer (you might need to have the exact paths to make it work on linux):

~/STMicroelectronics/STM32Cube/STM32CubeProgrammer/bin/STM32_Programmer.sh -c port=SWD -d build/oled_test.elf

Then run:

openocd -f interface/stlink-v2.cfg -f target/stm32f1x.cfg

Now set your breakpoints and hit F5 after choosing GDB as debug configuration
