I got: https://www.unmannedtechshop.co.uk/apm-2-8-flight-controller-board/
I'm trying to load a new firmware onto it using APM planner (Initial Setup) but I get:
"Unable to gain access to bootloader"
I have tried: Windows 8, OSX, APM planner 1 and 2.0.20
Different USB cables
Is there something wrong with this device?
