Seeing that the new Teensy 4.1 Board includes a RMII PHY i wonder if it's possible and what steps would be necessary to get the Teensy running as EtherCAT Slave. While RMII is not recommend by Beckhoff it is principally supported[1]. Has anyone ever tried this on a Teensy before or had any experience with it in principle?
