Hi,

I have a problem with the CFI Flash IP when I add MMU to my Nios II processor.

Without MMU, I'm able to the CFI table of my NOR Flash (Nios EP2C35 kit) with nios2-programmer --debug.

However when I add MMU, "No CFI table found".

What kind of problem do I have? It can't be an hardware problem, I can access to my flash with a NiosII configuration processor without MMU.

Someone can help me?
