Custom W5500 with ESP32 S3 ,SPI Working but "Link: DOWN" – No Ethernet Connection Detected

I am designed my schematic by referring this schematic ,here the RXN and RXP resistor values are 49R and cap c36-c41 is 0.1uf

cannot and should not use INTn to reset the W5500.

  • INTn is an output pin, not an input.
  • It is used by the W5500 to signal an interrupt to the host MCU (e.g. packet received, socket closed).
  • Driving INTn low externally can damage the chip or prevent it from functioning correctly.
