Hi!
I’m trying to run PX4 fmu-v3 on a pixhawk 1 with 2gb flash. I also need to build it from source from my project. We have previously ran ardusub on this setup but are changing to PX4 now. I have built and flashed PX4 onto the pixhawk without issues. The pixhawk is ran with a Jetson through mavlink and the control is done via ethernet and a joystick. The issue is that there seems to be something weird going on with the control of the motors. As soon as I disarm the drone three of the eight motors start spinning slowly, and when I’m in manual control the joystick seems to randomly control some of the motors. And the motors are all spinning very slowly.
As far as I can see I have set up everything I should in QGroundControl. I have chosen the correct airframe and set the PWM main signals to the motors and specified the correct min, max, and disarmed values. I have also configured the joystick. Again, the control of the drone was running perfectly with ardusub, so there shouldn’t be any hardware issues.
