Accessing External Memory Devices

Hey all,

I am using uVision 3 and a Phytec 2294 board.

I have an external memory device connected to the phytec expansion board. The external device is using /CS0, although from talking to phytec, I am not sure if that is quite right.

I have set up the external memory space in the project options like so:
Start: 0x80000000 Size: 0x4

When I define a variable like :

#define volatile var x __at 0x8000000

and step through my code, any write/read to that variable doesnt seem to take place at the right addresses.

Can anyone give a clue as to what I may have missed?
Thanks

Doug
