What is this? I know that GSOC is google summer of code, but what is this helloworld.bin file? Why is it posted here? What does it do? Who might want it? How do you install and run this if you wanted to use it?

Many questions, little information.

It's a requirement of the beagleboard.org GSOC, the user just used the
wrong mailing list.

… talking about iio …

Here is something for you to debug on the beagle bone black:

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 
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

You should ask this question on the Linux-IIO mailing list.
