Hello ted,

I contacted Terasic. Today they informed me that they tried to do the flash programmer to load my project onto their DE0 Nano board as I requested.

And they can do it without any problem. I don't understand that why I cannot do it. I have tried with two of my boards.

Another method is to try to create a jic file then program it onto the board. I also have done it.

At last the software became bootable. BUT WHY IT NEEDS TWO MINUTES???
