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!

Unfortunately, tracing features are not supported at the moment. They are part of our roadmap.
