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?
