MMU support status

HI all

I have seen Hippo has placed a MMU system in the Wiki. Just for playing, I have tried to compile a kernel for it.

When including MMU support, compilation barfs at fork.c (as it did in the past).

When not including MMU support, kernel image doesn't boot.

I don't need MMU support in my design but I would like to know what is its current status

TIA

    The MMU-enabled NIOS needs a new gcc (which is a gcc4) and thus a new toolchain. Same has been created by WindRiver on account of Altera and is not publicly launched to Open Source yet. Unless you have an NDA with Altera, you will not be able to compile anything for a NIOS-MMU CPU.
