Hi, I'm runnig 3.5-rc2 kernel on my board with hmc5883 magnetometer. I've check iio documentation but cannot figure out how to read data from device. Node /dev/iio:device0 is properly created. I try both test programs: generic_buffer and iio_event_monitor but both gives me an error: iio_event_monitor: ./iio_monitor hmc5883 Found IIO device with name hmc5883 with device number 0 Failed to read event from device: Bad file descriptor IMO this is because hmc5883 don't have event_attrs set and then this fail. generic_buffer: ./generic -n hmc5883 iio device number being used is 0 Failed to find the trigger hmc5883-dev0 Not sure about that one but seems trigger is missing (hmc5883 use INDIO_DIRECT_MODE) Is there other way how to read data from device or only possibility is by reading sysfs (no polling ?) ? Or it is just simple open device -> sleep on poll and when wake -> read data?
