    Ethercat on Teensy 4.1?

    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?

    I have an i.MX RT connected to a Microchip LAN9252 as an experimental EtherCAT slave. This has built-in Phys and handles all of the realtime EtherCAT comms. However, the LAN9252 is an absolute pig to talk to with its indirect addressing mode. Fortunately, Microchip have just released LAN9253 and LAN9254 which seems to allow direct addressing. I await my samples...
