Hi MSchmitt and Frank

Finally I found the error origin. As I suspected the configuration load failed because the soldering of the cycloneIII. As a last desperate resource I push down the component against the board and try to program and.. surprise!! it works..

I resolder again the component and now is fine. The surprissing part is that before of that, I checked pin to pin the continuity connection (without apply a big force) and it seemed OK, but not.

Well, I´m more tranquil now. Thanks for your answers, I will use all your advices in the final design of my board

Best regards
