Finding registers of PHY

Are you sure 88E1111 has internal registers? This document:

http://smartdata.usbid.com/datasheets/usbid/2008/2008-q4/88e1111.pdf

show a block diagram and there are no internal registers. The external signals controls the operation of the PHY.

Thank you my dear friend for your answer,

Yes I'm sure.

but if you look at it exactly,you'll find it.

The registers are described in the data sheet, however, access to the 88E1111 data sheet requires an NDA with Marvell.

Cheers,

Yes i know that,

I wanna know what if someone hadn't that NDA.

I mean isn't there any other source?

what Should "I" do? :D

NDA = non-disclosure, which means that you're not meant to share. You need to get your own version, i.e., contact Marvell.

You could probably also look in the Linux source for the Marvell device driver. That will tell you most of the register settings. I believe a lot of them are generic between 1GbE PHYs.

Thanks dear Dave,

I checked it. But Unfortunately Marvell doesn't support in my country.

What are Linux sources for Marvell?Can you explain a bit more?

Many of the Terasic boards contain 1GbE PHYs. Look at their NIOS II Linux source code. The code may not explicitly look like its talking to a Marvell PHY, however, whatever code is talking to the PHY via the MDIO bus must be accessing registers that you can also use.

Thank you dear fpgaengineerfrankfurt ,

I found the datasheet and I wrote a code which is able to write/read to/from the PHY.

I needed to change the MAC speed in register 20.6:4 to 100 Mb/s.
