I do see this event fire in my logs so it appears this is working. Just for my own edification, what does this event specifically signify? It signify that link between KSZ8081 and your PC was negotiated and is up, i.e. PHY MDI link status, check details here . In any case, this tells you that the P...

Try to reduce SPI frequency and use wires as short as possible with matching length.

For further debugging, try to switch PHY to loopback mode. You need to write simple application. The best approach is to not use LwIP for this. Just initialize Ethernet without ESP-NETIF init and register your own Rx callback function using `esp_eth_update_input_path`. Then check with oscilloscope i...

I checked the internal documentation and this EMACCSTATUS_REG register is optional and is present only when the MAC is configured for the SGMII, RGMII, or SMII PHY interface. Therefore you cannot get correct data from it when in RMII mode. If you need to know PHY speed or duplex, use: esp_eth_ioctl(...

Do you implemented some custom application or you just run the Ethernet? If you have your application, please check that you properly handle memory, i.e. you free heap when you no more need it.

What IDF version do you use? Could you please provide logs?

I see that you've mentioned the CS is pulled low on the board. However, would it be possible to connect CS to the GPIO? I have this type https://www.amazon.de/-/en/TECNOIOT-USR-ES1-W5500-Ethernet-Converter/dp/B07RGLN436 of W5500 module and when I connect the CS to GND it does not work.... It theoret...

Please make sure you also connected the W5500 interrupt output to your ESP32.

Try this one https://github.com/espressif/esp-idf/tr ... ork/bridge. I merged the update to support WiFi just yesterday so please wait few days to be synchronized to GitHub. Here you could find more info and work in progress version: https://github.com/espressif/esp-idf/issues/5697

I'm glad to hear you were able to resolve your issue. However, I'm bit sad about your negative experience. Therefore, I would like to provide clarification to some topics. that code doesn't appear anywhere in any example within any version of the IDF that I could find. Of course it doesn't appear an...
