4 years ago There's not much Cyclone IV specific code, PLL configuration is probably the only notable thing that would need some porting work. However, I wouldn't recommend starting from OSSC code here but to look into DExx-vd_isl repository which has much of the core code rewritten and targeted for a couple Cyclone IV/V development boards. That project is still very much in progress but it should be much better starting point.
Since I would like to start using a OSSC but also want the OSSC Pro, Quartus Prime Lite Edition is compatible, but is the current OSSC software capable of running compatible on a Cyclone V?
Perchance there is already a OSSC Pro development image out there to try, but I haven't seen it myself.
