I've got an AQ board here which I was running the AIMU on with r224 successfully for a while, and yesterday got around to installing the DIMU and flashed r380 onto it. I installed it in the copter, connected to it and configured the radio and mixer etc, and everything was looking good, but after arming it and raising the throttle above 0, the motors would start, but there was no response to the throttle above the starting speed, and tilting the copter didn't produce any speed changes on the motors.
I reconnected the battery to investigate, and now the board just powers up with the red power light on, but doesn't progress further than that. I am able to reflash the firmware, but am unable to connect via FTDI cable or 3DR radio.
I'm really hoping the board hasn't died. I checked my DIMU soldering, and it's all clean with no solder bridges or anything, and I have ground wires on the connections for my LEDs and gimbal tilt. Nothing was connected or disconnected while it was powered on, so I thought I would be safe from any voltage spike issues on the MCU. I have the recommended resistor on the telemetry signal line.
Has anyone seen this before and know how to proceed from here?
