CFI Flash and MMU

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 see the CFI Tableof 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 or pinmap problem, I can access to my flash with a NiosII configuration processor without MMU.

Someone have met this problem before?

Thanks in advance.
