ESP32S3 does not have internal EMAC. Therefore you cannot connect Ethernet PHY to it. You have to use SPI Ethernet module which has the EMAC integrated. Or you can switch to ESP32 or ESP32P4 if it satisfies to your needs. BTW, regarding documentation. I'll fix that introductory section to make it m...

I am doing a project where I want an dedicated RGB8 interface and intergrated EMAC for ethernet in the MCU. I read the ESP-IDF of esp32s3, it said '' ESP-IDF provides a set of consistent and flexible APIs to support both internal Ethernet MAC (EMAC) controller and external SPI-Ethernet modules .'' h...
