Hi Kelly,
thank you for the repsonse, but I had already been using elcipse installed the in the way you had mentioned.
I have managed to get further now by using a simple Quartus project a colleague had created for me. Currently I am not sure what he did differently to me, but I suspect it is down to him manually editing the address space, whereas I was letting the platform designer Auto Assign Addresses. This is just speculation however as I am currently happy working on software rather than fighting against Ecplise, I shall wait to see how I can break it later!
Many thanks
