W5500-EVB V1.0 external flash server

Hi, I’m developing a server project, and I need to store an HTML page in the external flash, because it exceeds the limit of the MCU, I have some sample programs but I couldn’t load the page and read it. I tested the HTTPServer_LPC11E36 program with a small page stored in the MCU, and it worked perfectly. I’m using the W5500-EVB V1.0 board and the MCUXpresso IDE. Via FTP I can write the page in memory but I can’t read the page. For now, thanks.
