Hi Chris,

you might still want to look at your scale. I have never seen a case where the scale from the calibration was wrong so far...
Also if you are working on MPU60x0 drivers, it would be cool if you do that with recent code and using the almost done (and hence totally untested) mpu60x0 peripheral in the mpu60x0 branch.

Cheers, Felix

It is ok now.
I made a subsystem for the drotek 10dof v2 imu with the magnetometer also operational not as a separate module.
The module method was not working because  the HMC5883L  is connected to the internal mpu6050 i2c  bus on the Drotek imu v2.
I also made the MPU6050 read the magnetometer it self and load the mag data to its registers  but sometimes it freezes so it needs some more work.
Right now i bypass the internal I2C bus (via mpu6050 configuration) and connect the mag to the main I2C bus.

i have a IMU similar to aspirin (mpu6050 + adxl345 + hmc58xx + ms5611) running on v4.2 .
2 months ago i tested the same IMU on master and it worked fine.
