Taking screenshots of sure configuration pages could be very helpful for reference, particularly the Ports tab. This ensures you realize which port is assigned to every peripheral, which could be unclear from CLI strains alone.
Downloading Processor Flash
As a complicated technique, you may clone all the processor reminiscence, packaging the firmware and configurations right into a single file. This technique is helpful as you gained’t have to fret about firmware variations. Nevertheless, it requires extra software program like STM32CubeProgrammer.

I exploit this technique continuously, because it permits me to modify between totally different Betaflight variations rapidly and even change between iNav and Betaflight for testing functions.
