Installing the extension
- Install ESP Debug Extension on Visual Studio Code.
- Click on the "Install" button.
Prerequisites
- Make sure to use ESP-IDF and have GDB Stub enabled:
  - Component Config -> GDB Stub -> GDBStub on runtime.
- Build and flash your code to the board.
Configuration
- In Visual Studio Code, go to Run > Add Configuration... > ESP Debug to add launch.json with default configuration. Or you can create it manually with the following content:
```
{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "esp-debug",
            "request": "launch",
            "name": "ESP Program",
            "program": "build/your_app.elf",
            "port": "COMx"
        }
    ]
}
```
- Change the default properties in launch.json to match your project.
NOTE: If you want to synchronize the selected COM port with ESP-IDF extension you can do as following example:
```
"port": "${config:idf.portWin}"
```
Start debugging
- Press F5 and now you can start debugging your project.
NOTE: This extension does not support flashing your code to the board yet. So make sure you flash it before you start debugging.
