My APM2.5 just quit working while I was doing the final setup on my plane. It will no longer connect via Mavlink or 3DR telemetry to MP. At the time, I was mixing rudder control on my DX7-s to operate the FPV camera PAN servo with the GEAR switch. Everything seemed to work great, then the APM went completely dead. The rudder travel was set at 150% for the long rotation servo.
I had 3DR telemetry, FPV w/ MinimOSD, operating perfectly, Spektrum radio was calibrated and had 3 modes: MAN, STAB, RTL programmed. Aircraft surfaces responded to STAB correctly, then suddenly, nothing.
I disconnected everything including the GPS, and connected via USB to the MP. Connection fails at "Got param GND_ABS_PRESS" (62 of 183). I got access via Terminal and reset the EEPROM: no difference. I have since tried loading other older versions of Arduplane, but there is no accel, mag or GPS response.
Below is the schematic of my flight system. I can not see any reason for the failure due to my design. Please look it over and see if it is all correct. Also, I video recorded the functionality of the system prior to failure so that I could feature it on my website. I can post that video as well. Everything was working perfectly before the sudden failure.
Any help appreciated. I just went from "Ready For Maiden" to "Totally Discouraged".
