Flash Programmer on DE2

Hi Everyone!

I've recently received the DE2 board. It's full of nice things but I want to be able to use it the same way I use the other Altera boards (meaning with the flahs programmer).

When I try to download a design with a read only file system to the device's flash I get an error. I've included the transcript for the flahs programming procedure:

Has anyone succssfully tried this before ?

On the same subject, does anyone know the reason why a read only filesystem can&#39;t reside in an epcs device ?
