Finding PHY registers map

Hello friends,

I'm currently working with ALTERA DE2-115 board.
I need to know the internal registers of this board's PHY. The PHY is Marvell 88E1111.
After searching, I found a product brief. But it hasn't mentioned the map of the registers.
Has anyone experienced this?

Thanks in advance

Customer support for Marvell products and services requires an approved Non-Disclosure Agreement (NDA). Marvell Technical Representatives will not be able to respond to your technical questions without an approved NDA on file. If you do not have a Marvell NDA on file, please contact your local Sales Representative.

Access to NDA product documentation requires an Marvell Extranet account.

This is why you can't find any information on the registers internal to the part, or any user guides for the device. I'd try and contact someone in support at Marvell and see if you can't get an NDA with them. Otherwise go through Altera's documentation and see if they have a Nios driver for the PHY and reverse engineer the register map from that.

the best free source for things like this is often the linux kernel drivers. the drivers have mostly just the useful information, so some of the less used extras would be left out.

I have no idea why marvell hasn't released an open datasheet for the M8E1111, as it has been out for a very long time at this point.

here are some examples:

Thanks my friend.

I checked the Altera's documentation, there is a Nios driver for the PHY, but it doesn't mention PHY's registers at all.So I can not do reverse engineering.

Thank you my dear friend.But it is really difficult to extract the required information from it.
