Seeking for help with W5500 Chip integration with Atmega chips. I have integrated the W5500 with ATMEGA64 over SPI and attached the minimalistic schematic for your reference. The Ethernet is working completely fine most of the times but I am facing some issues with the link status randomly.
Sometimes, the LINK Led on the LAN Connector side starts blinking and it doesn’t connect to the internet then. I have to power reset the complete system to make it work. Ethernet cable unplug/plug doesn’t work at that time.
Can you please let me know what could be the reason if the link status led continuous blink at a period of 1 sec roughly??
I would appreciate for the help. I am stuck with my complete development. Let me know if you need any other details from my side.
