STEVAL-MKI159V1 with STEVAL-MKI109V3 - Unico does not allow magnetometer configuration?

[peter.wrigley]

I have bought these two evaluation boards. The accelerometer and gyroscope work fine. The magnetometer settings in Unico do not change the magnetometer registers. Reading magnetometer registers returns ff at all times. If I have a logic grabber connected to the I/O pins of the sensor the board then Unico does not start properly (complains WHO_AM_I is wrong).

I cannot read anything out of the magnetometer. Is this a known issue?

Minor update, results identical on Windows 10 and Ubuntu 18.04. Using Unico 9.0.0 and ProfiMEMSTool 3.2.6, up to date as of yesterday.
