Hi,

Real-time watch is only supported for microcontrollers that allow reading the target’s memory without stopping the target. Currently only ARM devices support that feature.

Although it is technically possible on Linux-based devices like Raspberry Pi, VisualGDB doesn’t support it as the real-time view will not be accurate and would not cover library functions. Instead, for Linux-based devices (including Raspberry Pi), VisualGDB supports the valgrind profiler that can precisely measure the time spent in each function.
