Since yesterday i hooked up COM1 of my G120 board to my desktop computer in order to monitor debug messages without the need of USB. I am not using Debug.Print but a method to write directly to COM1. My application was running and suddenly stopped. MCU exceptions were outputted to COM1: Below are a few exceptions that i copied from the Teraterm window. I had to flash the firmware in order to get the device running again.
