i'm just trying to download in a nios development board (with stratix ep1s10 device) just a really simple design, using the seven general purpose led diodes and also the four "general purpose" switches of that board. i just intend to switch on one led while pressing one general-purpose switch.
in appearance, the download from this code to the board is done without errors. i've assigned properly the stratix device pins related to the switches and leds, and the quartusii programmer while the download ends without errors... but in the board still remains the "safe configuration" (no change happens)...
are there any compulsory pins to be assigned?
thank you very much http://forum.niosforum.com/work2/style_emoticons/<#emo_dir#>/wink.gif
