SWO ITM monitoring issue.

Hi , I build my .elf target by following Makefile. I monitor the ITM0 on my VSCODE and I receive nothing. [ using STLINK and OPENOCD] please make a clear tutorial on how to config the extension for on STM32 / openocd to view the graph or have an SWO terminal . here is my Launch.json configuration:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name":"Cortex Debug",
            "preLaunchTask": "Flash", 
            "preLaunchCommands": ["monitor arm semihosting enable"],
            "cwd": "${workspaceRoot}",
            "executable": "./build/RTK-DW1000.elf",
            "request": "launch",
            "type": "cortex-debug",
            "servertype": "openocd",
            "device": "STM32F103C8",
            "configFiles": [
                "interface/stlink.cfg",
                "target/stm32f1x.cfg"
            ],
            "svdFile": "./STM32F103.svd",
            "interface": "swd",
            "swoConfig":{
                "enabled":true,
                "source":"probe",
                "swoFrequency": 2000000,
                "cpuFrequency":72000000,
                "decoders": [
                    {
                        "port": 0,
                        "type": "console",
                        "label": "SWO output",
                        "encoding":"ascii"
                    }
                ]
            }
                
        }
    ]
}

Thanks

Yes, your printf’s will work just fine. You can even do getc() if you want.

You can try the new preview version of SWO support. It is available as a pre-release from the Market place.

You can customize how SWO works as well.
