I am not sure how you use GDB to debug — the firmware runs on the microcontroller and it’s not a process running on your computer, so I am not sure how to use GDB to, say, set breakpoints and step over the firmware code. There are way to debug a microcontroller such as JTAG. That requires hardware support, and I’ve never used JTAG myself. For the moment serial printf is the best way probably.
