How could I complie more Pins than free I/O Piins that Devices Provided

Hello Everbody,

I am trying to communicate between the cyclone 2 EP2C5Q208C8N and the SDRAM, (Model: IS45S16400F , 1 Meg Bits x 16 Bits x 4 Banks (64-MBIT),SYNCHRONOUS DYNAMIC RAM).

(I use Quartus 8.1) But to understand how it works I tried the Tutorial, but in this tutorial they use the NIOS 2 Processor, so I need to understand this processor. So I began the tutorial “My first NIOS 2 processor Getting started”. Problem: The examples are only for the cyclone 3 or other fpga`s. So I chose another tutorial:

“Nios 2 Development Kit Getting started”

Problem: I have the same problem like senlin.

But I don`t know which signals/pins I have to change in the assignment editor that the software don’t give me the error message again.

Somebody can help me, please?
