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 😉
