did you check the design guide or layout guide of dm9000a?

I&#39;m having a very similar problem with my DE2 board.. it sends ARP packets, and my host pc responds to them, but I don&#39;t think the board understands the response because it sends another broadcast right away. This happens three times after every ping command given to the DE2 board. It has a static IP and is connected by crossover cable to the host pc and uses the DE2_NET example.

How else can I test it? Thanks in advance http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/smile.gif
