I had a crash a couple of weeks ago that damaged the IMU. It would spin up but would not auto stabilize. After replacing the IMU I got it running again but as long as I have the magnetometer plugged in, the boards will not light up at all. All I get is the ESC boot sounds and no lights at all on the IMU or APM board.
Unplug it and it's fine. I did have one of the wires come off the magnetometer from strain so I soldered it back on. Maybe I should just solder it on the IMU but would like to figure out what the problem is that would cause this.

I've stopped using hte configurator except for viewing. I only use arduino 0021 serial monitor to do the setup via CLI.
What about the calibrate transmitter screen in the configurator? Does that need to be done or is doing all the setup in CLI sufficient?
Yes it was a bad cable. Had to get the loupe out but it looked like the molex connector had a problem with one of the pins so now I have the magnetometer soldered on. I updated the code for comp down pins fwd but I'm having a problem.
When I go to CLI and enter c to do the compass offsets it says the normal message
2 secs.
1 secs.
starting now…
But it doesn't go any farther.
Also when I take the board out of CLI and boot up I don't get a green solid light on the IMU. I was getting it before I soldered the mm on so I'm wondering if there is some defect in the mm board?
Also I'm having an unrelated(?) problem. I'm using xbees instead of USB and when I enter CLI mode I get a partial menu that ends with:
r - Reset to fa
All the commands work except compass offsets. Is it possible the xbee is bricked? I've had that happen before but I would think that would cause NO communication. I also tried uploading to the board via arduino 0021 but it would end up giving an error. The only way I can upload software is via USB. I'm wondering if this is causing the communication problem with setting the compass offsets.
