In the existing ls1021atwr board , we were adding a marvel switch 88E6161 with the phy addr 0x4 in the MDC/MDIO
path. But it is not reading it..
we are using the default mdio command in the u-boot , which is used to read the existing marvell phys 88e1111.
when we probe through CRO , while reading the switch , Turn around (TA) sequence is not appearing in . whereas as
per the switch timing diagram(SMI) it is must.
Is there any way to create TA in the in-built mdc/mdio? .
will the Switch 88E6161 work with in-built mdc/mdio ..? or should we do gpio based mdc/mdio?
How to go ahead with this?

Sorry I didn’t get you.. what do you mean by traces..? CRO trace?
With regard to documentation I sent you the Timing details of the SWITCH WHICH WE USE..
W.r.t to the connectivity I explained you that MDC/MDIO OF ls102a is connected to the MDC/MDIO of switch (phy addr of this is 0x4).
If You need the complete datasheet of switch we use or anything else let me know ..

Please provide all necessary additional information (including traces and documentation) to make complete technical description of the issue.
