All peripherals are uplugged (note: when I had the peripherals plugged into the Pixhawk, all i got was the “no response from board” error. Unplugging the peripherals seems to have improved the situation somewhat). Have tried with both LiPo battery plugged in and unplugged.
My problem is Navio connecting to Mission Planner giving the error of “Access denied”, and in QGround “Could not create port. Access is denied” error is given.
