Been trying to update the firmware of my brand new apm 2.6 unit. I keep getting a no connection error after reading the hex while trying to update my firmware. I tried using flip to update the chip firmware and that seemed successful. Any ideas why I keep getting the no connection error? I have tried multiple machines, apm planner and mission planner, multiple usb cables, always get the same result.

After failing to upload firmware it goes on to install mavlink and then run through the initial setup. When it comes to calibrating the gyro/accels it skips through all the different quad position pictures very fast then says calibration failed. Does this make sense with the firmware issue? When I go to terminal and press connect it just displays a string of random looking text/characters. Which also doesn't seem correct. Thoughts?
