Hi Expert,

I am a newbie for Ethernet RGMII protocol. Currently using custom board of AM2434 controller. I want to establish RGMII interface with PHY IC(microchip KSZ9031RNX). I don't know which register i have to link with PHY.

I also have AM5749 EVM kit, in that same PHY IC is used. But unable to get the flow.

Please guide me to link AM2434 with PHY IC.

Thanks & Regards,

Hi Prasad,

I have created myphy.c and myphy.h files, but i have few query.

What is the difference between myphy.h and myphy_priv.h?
Is it compulsory to create myphy.h and myphy_priv.h?

Waiting for your feedback.

Thanks & Regards,

Hi Divyesh,

No significant difference. myphy.h is PHY interface header file which application should include while using the PHY.

_priv is driver internal file and not available for application to include it.

It's not mandatory to create separate files.
