    I am using VisualGDB Custom Edition version 5.5R5 (build 4124) with a current license in Visual Studio Community 2019 v16.9.4.

    Your page https://visualgdb.com/tutorials/arm/livevars/ says that you can use Live Variables with OpenOCD. I am using the ESP32 with an Omilex ARM-USB-OCD-H.

    The VisualGDB properties say that the selected debug method supports live variables; but the menu item Debug->Windows->Live variables is not present.

    Is there something I have to do to enable the menu item?

    Hi,

    The Live Variables (renamed to Live Watch in v5.4) and other live functionality only works for targets that support reading the memory without stopping the CPU. This includes most new ARM devices and RISC-V devices, but not ESP32 or ESP8266.

    Is there anyway to debug the FreeRTOS heap within VisualGDB? Even if only when pausing debugging.

    Sorry, this is only officially supported for the ARM devices.

    You could try extracting the heap parsing logic from our FreeRTOS plugin and creating a custom expression visualizer based on it, but it will involve non-trivial coding.
