I don't know your dev board: is that Spansion flash supposed to be used as a configuration device? Or it's rather intended only for storing user data. In the first case you need specific hw pin connections.

Thanks for the reply Cris. I'm pretty sure it's meant to be used as a configuration device, since it seems to be the only Flash memory on the board. The only other memory I can see is some 256 Mb SDRAM (K4S561632H-TC(L)75) and some a 512KB Static RAM (IS61LV5128)

I've attached the Dev kit schematic which might shed some light on the situation. Loading a program must be possible, because currently a demo program runs when the board is powered on. I'm somewhat of a newbie with FPGAs, so maybe there's another way to do this that I've missed?
