I've never done this myself, but it seems that the simplest way to do this is to write a UIO driver.

I'll take a look when I get home and see if I can implement a small examples using the SoCKit board.
Hey Howard, I tried doing the "Sending and Handling Interrupts" tutorial that you posted. I followed it exactly, but I am getting these warnings from the Qsys console. I have the exact same system that you have put on your forum..
If you could provide some insight into solving these issues it would be of great help to me :)
Cheers
Yeah, I was confused by those warnings too, but it turned out to not be an issue. The example will still work. I will add some stuff to the post to tell everyone to ignore the warnings.

Hi,
I would like to thank you for this tutorial. It has proven to be very useful in getting familiarized with the Cyclone V SoC system. :) Really appreciate it :)
Now, I have instantiated an avalon memory mapped slave in the FPGA fabric and I am trying to read from it using the HPS. I have enabled interrupts for it. I have attached a picture of the Qsys system. I have enabled FPGA-HPS interrupts, by checking this setting while instantiating my HPS module in Qsys.
I am able to read from this slave using polling in my C application. However, I would like to have interrupts when I receive any data from this slave.
Would you be able to give me any suggestions as to how I can do this?
Any help will be greatly appreciated :)
Cheers
