printf over SWO with STLink GDB in launch.json

[gjepali]

Hi,

I'm trying to set launch.json to use SWO. I can do it with cortex-debug, but what about the stlinkgdbtarget?

    "version": "0.2.0",
    "configurations": [
        
        {
            "type": "stlinkgdbtarget",
            "request": "launch",
            "name": "STM32Cube: STM32 Launch ST-Link GDB Server",
            "origin": "snippet",
            "cwd": "${workspaceFolder}",
            "preBuild": "${command:st-stm32-ide-debug-launch.build}",
            "runEntry": "main",
            "imagesAndSymbols": [
                {
                    "imageFileName": "${command:st-stm32-ide-debug-launch.get-projects-binary-from-context1}"
                }
            ],
            "swoConfig": {
                "enabled": true,
                "cpuFrequency": 170000000, 
                "swoFrequency": 2000000, 
                "source": "probe",
                "decoders": [
                    {
                        "label": "ITM Port 0",
                        "type": "console",
                        "port": 0,
                        "encoding": "ascii"
                    }
                ]
            },
        }
    ]
}

But it shows syntax error:

"Property swoConfig is not allowed."

because this is defined for cortex-debug (OpenOCD debugger), not for stlinkgdbtarget. I have no problem with OpenOCD, but starm-clang should be all in one solution and it's more elegant to use.

Does stlinkgdbtarget  have configuration to listen SWO?

Thanks!
