Weird APM IMU output

Posted by jaron on November 7, 2010 at 3:47am
I'm trying to get the ArduPilot Mega running but I've got this weird IMU output:

3690848062?profile=original


What I've done

- uploaded the ArduPilotMega Beta 1.0 firmware

- switched the protocol to GCS_PROTOCOL_IMU
- modified the protocol so that it shows Euler angles only
- didn't touch APM + IMU and opened the serial monitor

My questions
- Shouldn't the values for roll, pitch and yaw bet 0 at startup?
- Why are roll, pitch and yaw jumping (IMU stationary)?
- What else can I do to test the IMU?

    Yes I did. When I turn the APM + IMU on the A LED is green. When I run the test the A LED is out. I have no RC equipment or GPS hooked to the APM. The test looks like this:

    Did you do the CLI tests (including IMU) as instructed in the manual?
