Nios II 3C120 Embedded Developement Kit, Cyclone III Partner Page

Hi, I've met a similar problem, but I'm using DE2-70. This is because Pin_P28 has been assigned to nCE0 by the default setting in Quartus II. To solve, select assignments -> device... -> device and pin options... -> dual-purpose pins, and change the value of nCE0 to use as regular i/o, I think this should work :)
