Hello Team Toradex,
I have som-IMX8QM with Android OS. I am currently working on to bring up 2nd ethernet (fec2). I am not able to connect to internet and unknown with its working. Second Ethernet phy is KSZ9131RNXI, with is same used on som for ethernet 1. We have directly given the supply to KSZ9131RNXI and put the reset pin in pullup state with external resistor shown in schemetic.
