I've found the Exploring Beaglebone book to be invaluable for getting
the PRU working.

https://www.amazon.com/Exploring-BeagleBone-Techniques-Building-Embedded/dp/1118935128/ref=sr_1_sc_1

It walks you through configuring the PRU and provides example code for it.

It has a great website and companion code too. Chapter 13 is about the PRU:

Hello Loo Chuan Yin!

Hi guys, I tried to access the PRU with a simple blink test on Beaglebone Black using libpruio library. But I get this error,

**
initialisation failed (out of memory)

Find descriptions for error codes in the documentation. In your case the constructor failed, check libpruio: Messages. libpruio failed to allocate a small amount of memory (< 4kB).

Segmentation fault

This second message I do not understand. Any further issue is on your system, not related to libpruio.

I checked your code more in detail. This message is because your code continues despite the error in the constructor. Better stop in that case (as in the original stepper.c example).
