correctly connected and configured. I compare my design with the design under my install directory,but i can find anything different. what is the reason?how to solve it? I have just bought this new development board . So i don't familiar with the board at all.Link Copied

Make sure it works then compare this design with yours. regards Pavan http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/unsure.gif
