Nios II won't work after uploaded to the board

It finally worked!

I used TimeQuest Wizard to add the lines that Thormodo cited and added the reset pin to the PLL. It worked like a charm :)

As for the questions I asked, I found that the address is defined in the image generated. I believe that it is a logical address rather than a physical one, but not sure yet.

It didn't uncompress the linux image, but I was expecting it due to low memory availability. Now I'll fight the uClinux-dist rather than the Quartus II.

Thank you all again for your patience. As soon as I get everything to work, I will write a short tutorial and maybe an entry to the wiki.

Best regards

Bruno
