Hi,
VisualGDB currently only supports kernel event tracing for FreeRTOS: https://visualgdb.com/tutorials/profiler/realtime/freertos/
We are planning to support other OSes in the next releases, although we would not name specific deadlines currently. The only workaround until we support it officially would be to look into our FreeRTOS tracing implementation that is automatically added to the projects when the tracing is enabled (it provides hooks for FreeRTOS functions and sends structured events to VisualGDB using our semihosting API) and making a quick-and-dirty equivalent of this for your configuration.
