EPCS flash problem @ DE0-Nano board

Hallo,

very positive news: I got a solution from terasic support.

Here is the solution message:

>Yes, we do replace the EPCS chip with Spansion Flash, and the steps

>to process the EPCS programming should be a little different.

>Before programming the EPCS via nios-2-flash-programmer, users must

>add an EPCS patch file nios-flash-override.txt into the Nios II EDS

>folder. 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.

The override file was only included within the last shipment, 3 days ago,

so I have attached this file. I also have tested it and now it is working

fine.

many thanks to terasic support ! "The service makes the difference"

Also thanks to all other people here provided me with a lot of infos.
