EPCS flash problem @ DE0-Nano board

Hi Dave,

thank you for your well-meaning advice but I do not see any necessity

to verify this. Sorry, I have not enough time and in my view it will not

be purposeful. Maybe you have not read it yet, but I did open another

thread: http://www.alteraforum.com/forum/showthread.php?t=38687

I have attached a zip-file which contains the whole project to get the

problem reproduced and it will only take 3 min to do this. Open the project,

load the hardware, sof or jic down to the board via Quartus programmer.

In the folder "flash", you will find a script "myflash.sh". If you have

have a Spansion-EPC based board it will fail but it works fine on the

other boards. leon_heller also has verified it and a friend in germany

also today. Problem and symtom is always the same.

In my opinion, the DE0-Nano boards must be compatible and I hope to get

a solution from Terasic/Altera very soon.

Anyway , thank you very much for your effort and all the infos you have provided.

Cheers,

Reinhard

No problem. Just offering an option in case you were desperate :)

Cheers,

Reinhard,

Have you tried Quartus 12.1? You could just download the standalone programmer if you don't want to download the whole thing.

Leon

Leon,

I was in the opinion , you tried it on your DE0-Nano with version 12.1 already ?

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.

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.
