Hy.

Has anyone worked with 5475 (or similar) MMU?

I am trying to program with Reference manual, but there is not any example.

Thank you

Oscar

Is there a specific question that you have?

You can look at the Linux BSP to see an example (though complicated).

The MMU will allow you to "partition" the memory of the part, you can also make 2 "partitions" look like the same address and switch between them on the fly. I have yet to figure out how to do this but working on it. What is your specfic questions about teh MMU? If you just need a basic setup for it, that is easy and the compiler startup code should ahve done it for you, if not let me know and I will give you a basic setup.
