[Paparazzi-devel] Lisa M v2.0, aspirin v2.1 IMU freeze

Hi,

I have a lisa m 2.0, with imu aspirin 2.1. The IMU raw values (ACCEL, GYRO and MAG) all become equal to -1 when the baro MS5611 is exposed to the light!
It looks like the baro is not only sensitive to the light (as BMP085), but also perturbate the other sensors...
The most surprising is: that only happens using Fixedwing firmware. I couldn't get the same error using rotorcraft firmware.

What could be different between fixedwing and rotorcraft firmwares when using:
<target name="ap" board="lisa_m_2.0">
<subsystem name="imu" type="aspirin_v2.1"/>
 <configure name="LISA_M_BARO" value="BARO_MS5611_SPI"/>

Any ideas?

Regards
