Hello
Now and then when booting my image based on torizon-core-docker.bb and the latest toradex_4.20.y branch i get an error that the on-module phy could not be found.
I also experience this behavior on the latest torizon-core from tezi.toradex.com:

I really didn’t pay attention when this happens but i do now - most of the time i am pressing the reset button on the eval board.
Can this be related to 50890_U-boot: “Could not initialize PHY FEC” Issue After Software Reboot when uboot doesen’t get to do its things?
