Motor output on pixhawk not working

Hi, I got a new Pixhawk and i plugged all wires from the old into the new but one motor does not spin. I swapped one motor with the one wich did not turn and now the other motor is not turning wich means that it needs to be the output of the Pixhawk which makes the problem. So i wanted a refund which i got and i ordered the same model (Happymodel 2.4.8). But on the new Model i have the same problem what can i do? Can it be the firmware and i had flashed it wrong?..

Post your parameter file.

Nothing obvious in the parameter file. Post a .bin log after arming and throttling the motors up. You could also post a screen shot of Mission Planners Messages screen after after arming.
