Hoverfly What am I missing? HFP Board won't initialize with GPS installed

[APVXtreme]

I've got the HF Erista with HVP black board (new) and GPS with compass and external magnometer. We just replaced the HFP and HFGPS. Without the GPS board HFP fires proper no problems, everything is calibrated. When I install the GPS board all I get is an intermittent beep out of the ESC's. It won't even go though initialization.

Everything is connected properly, I've been drone tech for almost a year so it's not user error. I do think I am missing something though. I find the manuals very vague and not very technical.

Any ideas or thoughts would be appreciated.

Have you been through the HF zendesk help pages. On there are some more detailed setup processes which if you havent read might help. Sorry wish I could give you more but I havent yet used the GPS board.

Have you made sure to flash both boards with the same version firmware? Is your antenna properly attached? I have had issues initializing with GPS installed with faulty GPS antenna wires. I would try to re-flash your boards first.
