Hi,
ESP32 projects generally have 2 output channels: serial port (typically wired to the onboard USB-to-COM chip) and the application trace. VisualGDB supports viewing both:
- The serial port output can viewed via the Raw Terminal (activated via VisualGDB Project Properties -> Raw Terminal).
- Application trace can be viewed via the semihosting GUI (activated via VisualGDB Project Properties -> Embedded Debug Tweaking).
That said, the ESP-IDF has a relatively complex system of configuration parameters, so you would need to check them to see where the output of a particular project goes.
