Can MDIO be configured as open drain output?

Our customer wants to connect AM335x MDIO to 2.5V IO of other devices.

Best regards,

Daisuke

Hi Daisuke-san,

This is not possible. MDIO_DATA is not a true open-drain output. It can be connected only to 3.3V or 1.8V signal, depending on VDDSHV5 voltage.
