Avalon bus addressing wrong

Any idea why in my C code I poll address 0x8000 but actually see 0x0c00 (divide by 2) on Avalon address signals utilizing SignalTap? I would expect to see 0x2000 (divide by 4).

It's odd, I've never seen a problem like that before...

Could you also monitor the CPU's data master to see what it is doing and what address it is using? You can still trigger on your slave's read signal to be sure you get the right transaction.
