Hi All,
This is my first post here so I should start with a short introduction. I live in the Netherlands and have been playing around with RC stuff since I was 12. Now 30 years later still very active with all kinds of flying stuff.
I am relatively new to multicopters. I have a 250 quad with NAZE32 and fly that FPV a lot.
I wanted a larger quad for filming and built an Alien 560 frame with APM2.5 controller and GPS.
Untill this morning I could change settings and fly the quad. Mission planner had a new firmware for me so I upgraded to 3.2 Now it will no longer connect via USB to MAVLINK. On the board the ABC leds will only flash very faintly after power on.
I tried uploading older firmware but run into the exact same problem. When I flash the HIL quad firmware my ABC leds come back to life and MAVLINK via USB works again.
What did I do wrong? How can I fix my APM board?
Thanks!!
