TCP/IP Examples
PostPosted: Mon Nov 18, 2013 12:30 pm     Reply with quote
I bought the CCS Ethernet Development Kit and am going through the examples per the Exercise Book.

The second example, ex7b.c, wasn't working, so after some research and testing, I replaced function call MACGetHeader() with MACPutHeader(). With that change the program started sending UDP broadcast datagrams.

The next issue is that Wireshark is reporting that the datagrams have an incorrect Frame Check Sequence. I'm looking for ideas on what to do to correct this. I think the FCS is calculated in the Ethernet controller, so I'm not sure what to do.
