Not able to upload arduino code to A16v3 board

[ematicenergies]

here is ethernet arduino source code for KC868-A16v3:

i have tried this. it shows the IP address: 0.0.0.0 . Eventhough the lan is connected.

#include <ETH.h>
#include <SPI.h>
#include <Ethernet.h>

// SPI pin configuration
#define ETH_SPI_SCK  42
#define ETH_SPI_MISO  44
#define ETH_SPI_MOSI  43

// W5500 control pins
#define ETH_CS        41
#define ETH_RST      1
#define ETH_INT      2

// Static IP configuration
byte mac[]      = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
IPAddress ip    = IPAddress(192, 168, 3, 55);
IPAddress dns    = IPAddress(192, 168, 3, 1);
IPAddress gateway= IPAddress(192, 168, 3, 1);
IPAddress subnet = IPAddress(255, 255, 255, 0);

void resetW5500() {
  pinMode(ETH_RST, OUTPUT);
  digitalWrite(ETH_RST, LOW);
  delay(100);
  digitalWrite(ETH_RST, HIGH);
  delay(100);
}

void setup() {
  Serial.begin(115200);
  delay(1000);
  Serial.println("W5500 Ethernet setup with ESP32-S3...");

  // Set up SPI
  SPI.begin(ETH_SPI_SCK, ETH_SPI_MISO, ETH_SPI_MOSI, ETH_CS);

  // Reset the W5500
  resetW5500();

  // Initialize Ethernet library
  Ethernet.init(ETH_CS); // Set CS pin
  Ethernet.begin(mac, ip, dns, gateway, subnet);

  delay(1000);

  if (Ethernet.hardwareStatus() == EthernetNoHardware) {
    Serial.println("W5500 Ethernet shield not found. Check wiring!");
    while (true);
  }

  if (Ethernet.linkStatus() == LinkOFF) {
    Serial.println("Ethernet cable not connected.");
  } else {
    Serial.print("Ethernet Connected! IP Address: ");
    Serial.println(Ethernet.localIP());
  }
}

void loop() {
  Serial.print("Current IP: ");
  Serial.println(Ethernet.localIP());
  delay(10000);
}



this is my updated code. check if the pin connections are correct or provide me some leads ASAP
