Hi Fabio,

> Could this problem be the same one as reported at:

The problem you link to describes a permanent issue, our problem seems
to be sporadic as most of our tests work fine (at least for a while).

> Which Ethernet PHY do you use? Do you have pull-up in the MDIO line?

Our hardware has the KSZ9021RN PHY, so the MDIO line should be pull-up.

Do you know if there are debug options that could help us determine the
cause of the timeout?

Best regards,
Mattis Lorentzon
