Just trying to build and run / debug the default, unedited STM32 project you get when you open STM32CubeIDE. After telling me I needed the download the ST-Link server for it to work, I did, then updated the board when prompted. It now gives me 'Info : stlinkserver already running, exit' and the program times out.
If it's already running, how can I turn it off? Or have I configured something incorrectly?
