Hi, I'm using fxos8700 accelerometer/magnetometer and fxas2100x gyro with Android 7.1.2 (release android_N7.1.2_2.0.0 for iMX6QP).
All sensors are detected in kernel. FreescaleAccelerometer, FreescaleGyroscope and, FreescaleMagnetometer are available under /sys/class/misc. Android sensors module loads without any errors.
Reading Accelerometer data in Android works fine. However, when I try to read Gyro data from Android application (Sensor.TYPE_GYROSCOPE) the fsl_sensor_fusion library crashes:

fsl_sensor_fusion is proprietary NXP library. I do not have access to source code to debug the crash.
Any ideas what might be an issue?
