DHCP not working on NE64! Please Help!

chinniwhites — Tue, 13 Jul 2010 21:28:15 GMT

I just bought an NE64 dev board and am currently in the process of trying to get to accept a dhcp address. I hacked apart the connecterapp and NE64_Vend_OpenTcp to try to make my own project. Please let me know what i am doing wrong here. Here is what i got so far:

* Description    : This file contains main() for the Connector_App demo
*                    code for the MC9S12NE64.
*                  It does initializations and calls functions in the

*             stack is also included in the MC9S12NE64 Resource CD.

I hooked up wireshark and noticed the NE64 sends out a discover message but nothing else. I used wireshark to see how the computer handles dhcp, and it sends about five different DHCP related messages. So my question is why am i not getting past the DHCP Discover message?
