WIZ550web External Flash Memory

Hi
I have a WIZ550web V1.1
I want to use External Flash Memory ‘AT45DB081D’ to store Webpages without TF card.
what should I do?
Thanks

Hi.
WIZ550web is already used to external flash memory.
WIZ550web is used to SD card and external flash memory together.
refer to below WIZ550web source code.

Thank you
