Re: [Paparazzi-devel] IMU Failure/Freezing

[paparazzi_guy]

All right. I just did another test and compiled some new data and logs when
the error occurred. How I tested this was I had the plane inside our
building and then stuck the body of the plane out the window. The PFD was
working fine when it was inside, but when the plane was outside it started
slowly moving in a random direction and was not responding when I moved the
autopilot board. After about 1000s I moved the plane back inside and the
elevator started responding again when I gave the IMU more and less pitch.
However, it seemed like the gyro values in Messages were still stuck and the
PFD still wasn't moving. So the problem is still inconsistent with what it
affects. Also, the RAW data was not moving during the test and the values
for x, y, or z were stuck at 1 or -1. Someone else was responsible for
testing the RAW data last time so I can not say with my own eyes that they
were ever moving when this error occurred.

Please feel free to brainstorm any ideas because many of us are perplexed by
this problem. Thanks.

Matthew
