I have two system having different kernel version and drivers(IIO) on which i can run the generic_buffer.c application .On one system it works fine but on the other it does not give the input reports data. I have checked that the system on which it is working has the following sysfs under /sys/bus/iio/devices/iio:deviceX (where X is 1,2,3...) buffer dev in_accel_hysteresis in_accel_offset in_accel_sampling_frequency in_accel_scale *in_accel_x_raw* *in_accel_y_raw* *in_accel_z_raw* name power scan_elements subsystem trigger uevent This is for accelerometer similiarly for magnetometer (in_magn_x_raw,_y_raw,z_raw etc) and for Gyrometer ( in_anglvel_x_raw,in_anglvel_y_raw,in_anglvel_z_raw ) and the one on which it is not working has the below sysfs under /sys/bus/iio/devices/iio:deviceX (where X is 1,2,3...) : buffer dev in_accel_hysteresis in_accel_offset in_accel_sampling_frequency in_accel_scale name power scan_elements subsystem trigger uevent Is the missing _x_raw,_y_raw and _z_raw component main reason for not working of the app,.Where I can enable them in the driver?
