hi,NXP thanks for your reply,I already have these two documents(and for imx8mm,it seems use fsl_sensor_fusion not magd to report sensor data).we are based in android 9 to develop our soft.and my understanding is that we need magd to report the Accelerometer data to framework and Application.but there is only Accelerometer sensor and there is no Magnetometer sensor in our board,so magd will exit ,because it can't read “FreescaleMagnetometer” poll input device. so my problem is how we can report the Accelerometer data to framework and Application,without Magnetometer sensor in our board. and we also found that it seems fsl_sensor_fusion still can't report Accelerometer data to framework.
