Hello,
At first thank you for your response.
Well, I was able to run Linux on the board, when I used the sof and ptf original files from the demonstrations, but when I generated new ptf and sof using the web edition quarterus software, Linux isnt booting, or I cannot download the Linux Image into de2-70 borad (If I only generated new time limited sof and ptf and didnt change anything in the demostration project). I of course keep the window with sof configuration running.
So thats, why I think the Linux Image isnt possible to use with time limited sof file for some reason.
