My customer wants to use MDIO interface in ADuCM320.

And they already confirm the operation of MDIN interface in ADuCM320 using ADI EVM.

But they have some problem using MDIO interface of ADuCM320 in their test board.

They say that their code is operated normally using MDIO interface in ADI EVM, but it seems to have a problem in their test board.

So they request your confirmation about their configurations and schematic.


Please refer attached files with their schematic and GPIO configuration.

(Their configuration is difference from  a configuration of ADI EVM.)


1) Would you confirm their schematic and GPIO configuration in attached files?


2) Would you let me know any parts(configurations) of I/O (external) interfaces  affecting MDIO interface?


3) Would you suggest any opinions about this issue?


Please advise me ASAP.


If you have any questions, please let me know.
