MCF5282 - Fast Ethernet Controller

venki_02 — Thu, 13 Sep 2007 12:42:50 GMT

HI,
               I am a basic level programer in MCF5282. I have been getting confusion about the functionalities of FEC(Fast Ethernet Controller).
              My confusion is that whether FEC generate IP address or not. If anybody knows about the
functionalities of FEC and IP address generation or any related programs. Please suggest me
in this regard would be helpful for My project requirement.

Venkat,

The FEC is the Ethernet controller and has no knowledge of addressing at the higher (TCP/IP) layers. The FEC has a physical address that is globally unique, as assigned by the IEEE Registration Authority.

You must program the Ethernet address (the physical address) by writing the PALR and PAUR registers in the FEC.

IP address can be generated automatically, if your application supports DHCP. DHCP is an Application Layer protocol in the TCP/IP suite, the FEC does not interpret these messages.

For more info search "TCP/IP" on wikipedia.org

Regards,
Joel.
