master - slave multi-core nios systems

Hi,

i am trying to design a system with 6 nios processor which runs with master - slave system. i want to run 5 nios at the same time with triggering these systems with master nios processor. I tried intel's multi-core example on youtube but i got these issues;

• i couldn't set master-slave connection. When i started slave nios for waiting control signals, it just run all codes without waiting master nios trigger.
• when it waited control signal and got it, slave nios C code didn't run properly.

how can i fix it?
