IAR Debug with St-link

[meteusteler]

What should be launch.json configuration for debug with St-Link?

You could try something like this, don't forget to fix debugServerArgs to fit your hardware.
Replace APP.out with your ELF output, download arm-none-eabi and openocd and fix the paths

      "type": "cppdbg",
      "request": "launch",

Hi, it seems to be an OpenOCD problem, try to run it manually with cmd.exe and look for errors on the output:

"C:\Users\*\Desktop\OpenOCD-20170821\bin\openocd.exe" -s "openocd\share\openocd\scripts" -f interface/stlink-v2-1.cfg -c "transport select hla_swd" -f target/stm32F0x.cfg -c "adapter_khz 4000" -c "telnet_port disabled" -c "tcl_port disabled"

Anyhow I just tried out with openocd and ST-Link and it's working, this is my configuration:

      "stopAtEntry": true,
      "cwd": "${workspaceRoot}",
      "externalConsole": false,
      "MIMode": "gdb",

        },

      ]
    }
