Nice work Michal! I think these modifications are important to add support to other chips.
This ADIN1110 module (10Base-T1L) from Sparkfun is a good candidate: https://www.sparkfun.com/sparkfun-micromod-single-pair-ethernet-function-board-adin1110.html BR, Alan On Mon, Aug 25, 2025 at 3:59 AM <mich4l.mat...@gmail.com> wrote: > Hello! > > During summer I've been working on the driver for "OPEN Alliance 10BASE-T1x > MAC-PHY Serial Interface" compatible SPI MAC-PHYs.
