about multicore system

I am recently working on multicore system on DE2 Board.

The structure like this: cpu0 with uclinux, cpu1 without system.

cpu0 delivers program to cpu1.

Here's the problem:

1. There's 8mb sdram on DE2 Board. I don't know how to partition it, when running the SOPCBuilder, it seems that only one sdram module is sufficient. Is that true?

2. I wanna connect the reset_n of cpu1 with PIO from cpu0. It seems that when creating a symbol of the system ,only one reset_n appears. How to create two reset_n within one system symbol?

Thank you to you all!

    Babysnow,

    Did you successfully build the multicore system on the DE2 board? I am trying to do that presently and since the Altera Documentation is for the 'Nios II development kit', not for the DE2 board, I am facing several issues. Would like to know what document you followed.

    Thanks.
