Dear all,
I currently struggling with a task that I want to perform. I need to interconnect two microcontrollers through their ethernet mac interface through RMII without using a physical layer. After checking the whole Ethernet code available in the SDK, I am still not able to remove the physical layer initialization or at least fake a simple PHY layer.
Does anyone have some advice/clues about the possibility to perform this communication with the ESP32 ?
Thanks!

Re: ESP32 Ethernet mac2mac communication
FYI, you want to create a point-to-point link between two Ethernet MAC. There's a kind of interface call RevMII(Not RMII) which is aimed to this application.
For now, idf doesn't have support for this feature officially.
But we will eventually support it some day.

Thanks for your reply ESP_morris.
I was wondering if this could be done using the current configuration by simplify removing the auto-negotiation on the ESP32 the MDIO is discarded.

@DaViRiuS
did you got it work in the meantime to connect two ESP32 via its RMII interface?
i hope you are stil following this thread.
