MAC to MAC communication over RMII without PHY

Hi folks,

We have a need to connect an ESP32 to a companion system on the same PCB, using EMAC. As both systems support RMII, we'd like to connect them up without a PHY and do direct MAC to MAC communications.

Can a functional ethernet interface be initialised on ESP32 without requiring a PHY interface, is this supported by esp-idf?

If not, is this at all possible with some development? Any pointers appreciated.

Kind Regards,
Will.
