Greetings, I've had a couple of users report that they are getting occasional link drops when using IMX6 FEC on our boards which are using a Marvell 88E1510 PHY:
[ 9348.474418] fec 2188000.ethernet eth0: MDIO read timeout [ 9350.478804] fec 2188000.ethernet eth0: Link is Down If they bring the interface back up it works fine. The most recent version of Linux they have tested and seen this on is v4.9 with CONFIG_MARVELL_PHY=y Has anyone else run into this or know what the issue could be? Should there be any retries at the MDIO level or above? Regards, Tim
