Hello Undrea,

sorry for replying late.

I was looking for the information you gave me.

In order to set the PHY registers, do I need to connect to a PC with a USB cable or other means to control the PHY?

Do you have a PC application available?

Sincerely,

Kodai Aoyama

Hi Kodai,

Apologies for the delay.

You can configure the PHY registers by connecting the EVM to a PC and using the USB-2-MDIO software to configure the PHY.

Thanks,

Drew

Hello Drew,

Thank you very much for your comments.

I installed the USB-2-MDIO software, but I can't know how to use.

If possible, Could you share the instruction for setting USB-2-MDIO?

Hi Kodai,

Please take a look a the USB-2-MDIO users guide. Since you already have an EVM, information starting at section "2.3.2 Connecting to USB-2-MDIO GUI" will be most relevant.
