Custom PCB keep solid link LED

Hi! every one

We are working with Verdin imx8mm, dev board.

In our last custom PCB, we discovered that the ACT/LINK LED of the Ethernet Interface keep green when we unplug the ethernet cable; the PCB reference of the design it comes from:

Everything works fine for now,

Do you have any idea what could be wrong?


Please measure the resistance between Pin 10 of your Ethernet jack and the ground when the Verdin module is not inserted into your carrier board

Do you have a Toradex carrier board for Verdin modules, such as Dahlia or the Verdin Development Board? If so - do you observe the same behavior?
