MAC to MAC communication over RMII without PHY
Posted: Tue Oct 15, 2019 3:29 am
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.
