library problem?

[kangz543g]

Before ETH.begin()
E (5010) enc28j60: enc28j60_verify_id(549): wrong chip ID
E (5011) enc28j60: emac_enc28j60_init(1028): vefiry chip ID failed
E (5015) esp_eth: esp_eth_driver_install(250): init mac failed
After ETH.begin()

bad wiring ?

[kangz543g]

void WiFiEvent(WiFiEvent_t event)
{
switch (event) {
case ARDUINO_EVENT_ETH_START:
Serial.println("ETH Started");
//set eth hostname here
ETH.setHostname("esp32-ethernet");
break;
case ARDUINO_EVENT_ETH_CONNECTED:
Serial.println("ETH Connected");
break;
case ARDUINO_EVENT_ETH_GOT_IP:
Serial.print("ETH MAC: ");
Serial.print(ETH.macAddress());
Serial.print(", IPv4: ");
Serial.print(ETH.localIP());
if (ETH.fullDuplex()) {
Serial.print(", FULL_DUPLEX");
}
Serial.print(", ");
Serial.print(ETH.linkSpeed());
Serial.println("Mbps");
eth_connected = true;
break;
case ARDUINO_EVENT_ETH_DISCONNECTED:
Serial.println("ETH Disconnected");
eth_connected = false;
break;
case ARDUINO_EVENT_ETH_STOP:
Serial.println("ETH Stopped");
eth_connected = false;
break;
default:
break;
}
}
USE W5500,DO NOT USE ENC28J60???
