Using Altera's reference design


I am new with Altera’s SOC.

I try to understand how to use/extract reference design from Altera’s web site:

I actually need to use RapidIO, but couldn’t seem to find a Linux driver for it - probably there isn’t any :frowning:
But I did find a reference design .I’m not sure if it fits Arria V, Yet it might still be a good start, Right ?

The problem is that I find it hard to understand how to use this reference design because it seems to contains only software, but not hardware (?) - for example I can’t find symbols such as TX_DATA_BASE, RX_DATA_BASE , even when I searched all files (*) after extracting .

Thanks for any advice,
