Example FXOS8700CQ Driver Code in Datasheet gives 0,0,256 for magnetometer x,y,z values

The FXOS8700 is connected to Beaglebone Black via i2c.    The example code from the Datasheet is copied - print statements were added.   The accelerometer data seems fine but the magnetometer data is consistently 0,0,256.

 

The magnetometer control register 2,  FXOS8700CQ_M_CTRL_REG2, is being set to 0x20 for a burst read but it does not seem to work.

 

Not sure if this is being posted in the correct location....#
