Subject: iio on beagle bone black 3.13.6 kernel
Date: Sat, 22 Mar 2014 12:19:44 -0500	[thread overview]
Message-ID: <be30164b26d247c2576ba7369032bc23@reliableembeddedsystems.com> (raw)

Hi,

I use a beagle bone black with a 3.13.6 kernel and would like to get 
the
./generic_buffer test which comes with the kernel to work.

This is what I do:

echo 1 > /sys/bus/iio/devices/iio_sysfs_trigger/add_trigger

ls /sys/bus/iio/devices/
iio:device0  iio_sysfs_trigger  trigger0

cat /sys/bus/iio/devices/trigger0/name
sysfstrig1

echo 1 > /sys/bus/iio/devices/iio:device0/scan_elements/in_voltage5_en


./generic_buffer.out -n TI-am335x-adc -t sysfstrig1 -l 128
iio device number being used is 0
iio trigger number being used is 0
  sysfstrig1
---> Could not open /trigger/current_trigger
Failed to write current_trigger file

How can I get rid of this?

Is this a problem with my driver, or should I just create this magic
file somewhere?

Regards,

Robert
