Problem with Custom FPGA using MMU

First of all, you have to build a system with mmu.

If you can, I suggest to put a flash into your system.

Change Nios.h step is very important.

Try to build you zImage use make

If show error, check do you have that component or not?

If you have, change (nios.h) to map you component name to his one.

If you don't have, use make menuconfig to unselect that component.

It is hard to show how to do thought this, you can show more detail than we can discuss together.

Good lucky you can do it.
