Hello! I made a custom board with LSM9DS1 module on it. Pins SDO_M and SDO_A/G is tied together. I use SPI to communicate with module. When i write/read to/from accelerometer/gyroscope registers all works fine but when i am trying to read from magnetometer WHO_AM_I register or any other i get only 0xFF. I use separate CS pins for A/G and magnetometer.What may be wrong? As i understand it is not necessary to set up magnetometer registers to be able read from WHO_AM_I register. Don't understand what is the problem.
