No MDIO

Hi,

I am trying to send data from Cyclone III development board to another (same) board using Ethernet connection.

Data is transmitted successfully from the sending board to the receiving one.

My question is:

Is it possible to connect the two boards without enabling the MDIO option in the TSE MAC?

Thanks in advance

Best Regards

    Theorically yes, so You would control the PHY by Yourself. But why do You want to disable it? The core won't be able to communicate with the PHY, e.g. set required registers, reset the PHY, etc...

    Hi,

    Thank you for your reply.

    Actually I am trying to send data from a transmitting board to 2 receiving board -at the same time- via an Ethernet connection.

    Best Regards

    Well yes, but still You have to control the PHY. MDIO has nothing to do with the transmission itself.

    why do you want to remove mdio?

    To get rid off connecting the mdio to both PHY devices; as I am using single port TSE.
