Are you using the Ethernet in your application now? Can you not pull data from an HTTP server, and write that into a section of Flash?
Check the ethernet IAP examples, and application notes, perhaps you can copy some code from there.

Thanks for reply
i am using Ethernet udp for communication.i read for udp connection it is unsecured so how can pull secure data for firmware up-gradation?

Sure, UDP is not secure (encrypted) and provides no data transfer guarantees. You've to use/design your own custom protocol on top (maybe not so easy - see RUDP)
Or ... use TCP ;)

Thank you for reply.
if have any document which provide step of firmware up-gradation using tcp,calculation required flash or eeprom this kind of pre request calculation in document please provide us.
