W5500-EVB-Pico MAc address

I have been working on a project using a W5500-EVB-Pico-POE board and most of what I am trying to do is working. This is interface to a GPS module and display time on a 7-segment and LCD displays. However what I would like to do is also use this as a NTP server. But this is where my issues start. I have configured an IP address and port and the code says it is listening, but never sees any incoming packets. After digging deeper I have found that the software always returns a MAC address of 00:00:00:00:00:00. But for network comms to occur i am sure the hardware needs a valid MAC address. So do I have faulty hardware? or is it something that is software configured? If it is the later than how do I do this? I have tried the code below, where MAC_ADDRESS = b''\xDE\xAD\xBE\xEF\x00\x01'' But the MAC address is always returned as 00's. Can anyone help? Thanks Simon def setup_ethernet(): debug_print("[Ethernet] Initializing WIZNET5K Ethernet module...") nic = network.WIZNET5K() print(nic.config("mac")) # Set MAC address from config nic.config(mac=config.MAC_ADDRESS) mac_bytes_set = nic.config(''mac'') mac_str_set = '':''.join(''{:02X}''.format(b) for b in mac_bytes_set) debug_print(f"[DEBUG] MAC after set: {mac_str_set}") nic.ifconfig((config.ETHERNET_IP, config.ETHERNET_SUBNET, config.ETHERNET_GATEWAY, config.ETHERNET_DNS)) mac_bytes = nic.config(''mac'') mac_str = '':''.join(''{:02X}''.format(b) for b in mac_bytes) debug_print(f"Ethernet MAC: {mac_str}") debug_print(f"[Ethernet] IP: {nic.ifconfig()}") return nic
