Direct MAC to MAC connection

Question asked by rolfcrapp on Jul 10, 2018

We use an i.mx7D and an i.mx6UL in our system.

Together they communicate over Ethernet. Both are close to each other located (< 10cm)


Is there a way to connect both without the use of a switch or an PHY, to reduce parts and cost?

Maybe direct with RMII or MII interface? ( MAC to MAC)

We only found some answer, that it somehow should be possible, but it's actually not clear for us how.



how do the signals have to be connected?
