    Hi Ajith Kumar,

    The HALCoGen used to generate the driver layer will not support LAN9354

    It can only support DP83640 and TK111 and it doesn't generate LAN9354 by default. And i also searched for old threads on this driver but i don't find any thing useful.

    So, for this PHY you should need to create your own driver and should need to be integrated into the application code.

    Hi Ajith,

    Please verify the important API's used in the existing driver of DP83640.

    They are, 

    Dp83640AutoNegotiate, Dp83640PartnerAbilityGet, Dp83640IDGet and Dp83640LinkStatusGet.

    Try to create those API's for LAN9354 as well.

    If possible, first try to discuss with Microchip and verify whether they are providing any driver code for LAN9354 or not. If they are providing driver, then please verify their driver API's with ours and make necessary changes in according to our driver.

    If they are not providing any driver then you have to verify the datasheet of LAN9354 and should need to create those API's by understanding corresponding registers.
