Hi,
I have a question about the enumeration of MDIO buses.
We have a devkit that we want to use to program a boot flash of a PHY on a secondary card.
We tested the flashing of the PHY on the devkit and it worked.
Then we removed the MDIO lines (Clock and Data by removing the resistors) from the PHY on the devkit and wired the MDIO lines to the secondary card.
The PHY on the secondary card is exactly the same as the devkit.
When the PHY is in this configuration on the devkit, we don’t get an MDIO bus enumerated. We thought that removing the MDIO clock and data from the devkit PHY and attach them to the exact same PHY on the secondary card would still allow setup and communication to the PHY on the secondary board.
But that doesn’t occur. There is no MDIO bus when I list them using mdio.
Any suggestions how to make the enumeration work with this configuration?
Thanks
Malcolm
