razor_imu_9dof quaternion fault

hi,

I am working with the 9dof razor imu on the jetson tx1. I have installed the ros package ros-kinetic-razor-imu-9dof and calibrate the sensor. I ran razor-pub-and-display and everything seems good. When I look in rviz the sensor turns but at the south the boat jump 45 degrees. At the same moment the rostopic /imu values change form z: 0.99, w: 0.00 to z: -0.99, w: 0.00. It looks to me this is a Math problem. Has anyone encountered the same problem. How to solve this?

This happens if you run both programs.

I think something didn't work when you attached the image. It still links to postimg.org.

Seems that is indeed not allowed. Embedding is apparently also doesn't work. @tfoote?

Have not seen this, does this also happen without calibration? Did you try a new calibration?

Yes I have calibrate the sensor two times but still the same problem occurs and if I use the factory setting it's exactly the same...
