main objective of our project is to test spi master that we have built on MAX 2 cpld with nios acting as slave and also a host for our master.

we are not able to figure out how to use nios 2 as spi slave.

can we use spi core available with avalon interface for our purpose.

we also need ide code for nios 2 slave.

thanks in advance
