I’m using VisualGDB 5.4 on ESP32. I can’t use correctly the Live variables, while I was able to use it in an STM32F3 microcontroller. I can add variables, see the value, but can’t plot it.
Sorry, live variables require the target to support reading memory without stopping. This is supported by ARM Cortex-M and some Cortex-A targets, but not on ESP8266 or ESP32 targets.
