Yes, MDIO and MDC can be assigned to any GPIO which is output capable (check ESP32 TRM) via GPIO matrix. Also be careful with pins which are used as bootstrap pins (check datasheet).

What Ethernet module do you use? If auto-negotiation is enabled it should work out of the box.

Please see https://docs.espressif.com/projects/esp ... ac-and-phy and https://github.com/espressif/esp-idf/tr ... s/ethernet to find answer to your question.

Check examples at https://github.com/espressif/esp-idf/tr ... es/network if any suits your needs.

There probably is some issue with SPI as @DrMickeyLauer mentioned. 1) Check the GPIO configuration once again. Ensure INT pin is connected too. 2) If custom board is not used and just wires are used, use wires as short as possible and with matching length. 3) Decrease SPI frequency to e.g. 4 MHz. No...

If I understand it correctly you want to have both Ethernet interfaces to be bridged but, at the same time, to the Ethernet interface has its own IP address. Am I right? You cannot attach multiple netifs to single network interface. The correct way is to create netif for each interface and then add ...

Regarding release date of ESP32P4, please wait for and follow official statements on our web pages.

ESP32S3 does not have internal EMAC. Therefore you cannot connect Ethernet PHY to it. You have to use SPI Ethernet module which has the EMAC integrated. Or you can switch to ESP32 or ESP32P4 if it satisfies to your needs. BTW, regarding documentation. I'll fix that introductory section to make it mo...

Fuu, it was very long day today but I now fully recall why I didn't implement the SMI in KSZ8863 driver. It is not possible on ESP32! It's not fault of the ESP32 though. I'll try to explain. In terms of KSZ8863 terminology, SMI is non-standard version of IEEE 802.3 MII Management Interface (MIIM), s...

Once I have time I'll have a look at it in more details. I created https://github.com/espressif/esp-eth-drivers/issues/20
