Thanks for getting back to me, I've tried going as low as 5MHz with no success, and all wires are identical lengths. Could this be an issue on the W5500-EVB side caused by varying firmware as my W5500 board is a development board?

Thanks again for your response. Even after connecting the CS0 pin, the error still persists. I've also tried configuring the PHY reset pin on the ESP32S3 and connect it to the W5500-EVB with no success. The W5500 board I have is a development board compared to your board which seems much more compac...

Thanks for the reply. I've connected the INTn pin on the W5500 to GPIO4 (as specified by the sdkconfig file) on the ESP32S3 devkit and the error has persisted. Here is a screenshot of my sdkconfig file > Example Configuration: Screenshot 2023-07-13 135027.png Please let me know if there are any othe...

Hi, I have been trying to run the Ethernet Basic example (https://github.com/espressif/esp-idf/tree/release/v4.4/examples/ethernet/basic) on my ESP32S3-WROOM-1 devkit connected through SPI to a W5500-EVB board (https://www.digikey.com/en/products/detail/wiznet/W5500-EVB/8789607) and have been unable...
