When I try to connect via USB, it hangs on "got param ...". No errors, just sits there. Orange light blinks slower on the APM. CLI factory reset works, firmware update works, but can't connect.
Arduplane 2.76 freezes on got param PTCH2SRV_P
Arduplane 2.67 freezes on got param RLL2SRV_IMAX
Arduplane 2.50 freezes on got param FLAP_1_SPEED
If I just try to boot it, the B and C are solid (GPS lock?). I don't have a GPS plugged in...
