So I just got a pixhawk upgrading from a multiwii running APM via megapirateng. But now I’m confused about the firmware it’s running.
Correct me if I’m wrong: the pixhawk is based on the PX4 project. It’s running the NuttX Operating System but which flight controller firmware does it use? Does it still use APM? free netflix APM are the flight controllers right, so I guess it uses ArduCopter/ArduPilot firmware? What is PX4 autopilot then? As in the firmware I get from pixhawk.org, is it the same as the APM firmware? As in, does it make any difference if I use QGroundControl or android 9 the Mission Planner to load the firmware? QGroundControl and Mission planner are just ground control stations that communicate using MAVLink right, how can they upgrade the firmware on the Pixhawk? Shouldn’t I do that myself. And I’m guessing the firmware runs on NuttX?
