How did you create the trigger here? The trigger must be created according to its type. So far we have only hrtimer trigger type, so creating a trigger implies creating a directory in: /config/iio/triggers/hrtimer See: http://lxr.free-electrons.com/source/Documentation/iio/iio_configfs.txt#L83 > > $./iio_generic_buffer -N iio_dummy_part_no > iio device number being used is 0 > Failed to find the trigger my_dummy_device-trigger > > Its giving me ^ this error: > > What wrong I am doing? > > I have loaded all the modules including iio_dummy_evgen, iio_dummy. > > How I will be pass trig-sample as an argument to it? > and one more question how can I find Trigger-number of a trigger. > > I am facing same problem with iio_event_monitor:- > > $ ./iio_event_monitor /sys/bus/iio/devices/iio_evgen/poke_ev0 > Here you should use the device node. It is usually /dev/iio:device0. If there is not already created by a daemon there, create it using mknod /dev/iio:device0 c major minor. The major and minor can be found in /sys/bus/iio/devices/iio:device0/dev file/ > getting following error:- > Failed to retrieve event fd > > Same with all other events. > > This is working fine for me: > echo 1 > /sys/bus/iio/devices/iio_evgen/poke_ev0 thanks, Daniel. _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
