please help... suspect broken imu?

Hi guys...

 

This was not working, was working and now isn't working

 

I'm using APM v1.0 beta

When I connect the board up I get the usual

 

Init ArduPilotMega 1.0-BETA

freeRAM: 4051
MSG: <startup_ground> GROUND START
MSG: Demo Servos!
<startup_IMU_ground> Warming up ADC...
MSG: Demo Servos!
MSG: Demo Servos!
<startup_IMU_ground> Beginning IMU calibration; do not move plane
  <startup_IMU_ground> Calibration complete.
MSG: <startup_ground> NO airspeed
MSG: reset_control_switch0

 

Now the telemetry the roll is all over the place

WHen I move the board I'm not getting sensible results

Also I've hooked this up to HappyKillmore and the planes is spinning in the picture as expected

 

This was behaving like this then seemed to come alright but now I can't get it to stop

 

Is there something up with my X-Y sensors?

 

thanks

    You can try to take the IMU off APM and replace. We've seen this resolve some sensor issues caused by a flaky connection between the headers...

  • another issue...

     

    when I do the dipswitch settings I'm having some issues with that too

     

    I get this...see attached

     

    very strange too...

    the dip switch is not moving

    Run the CLI tests to narrow down the issue and post anomalous results here. Also, I note you're using old software. Please use 1.0 (not beta)
