Yes, due the the difference between the EPCS and Spansion Flash, there would be a littler different on process the Flash programming.

Terasic has updated the steps with its Usermanual: before programming, there is a EPCS patch file nios-flash-override.txt added into the Nios II EDS folder,which file can be found in the online CD resource.The patch file is available in the folder Demonstation\EPCS_Patch of DE0-Nano System CD. It needs to copy this file to the folder[QuartusInstalledFolder]\nios2eds\bin > (e.g.C:\altera\11.1\nios2eds\bin), then execute the flash-programmer. Thanks.
