HI Inon

I checked, there is no appnote that shows this support. There is no phy driver in c2000(f2838x) device. There is MDIO read and write APIs provided by Ethernet driver to read and write into PHY registers directly. This driver is in the C2000Ware SDK. You can follow the PHY Datasheet and read/write registers directly.

So if I'm using the SDK as is it will not work?

I will have to change using the MDIO, the content of the PHY register to meet

the SDK?

Hi Inon,

You can refer the C2000Ware SDK, which has APIs to use MDIO for phy reg modification. You can refer PHY datasheet to understand which registers are to be configured with which values, and accordingly use the SDK APIs.

The F2838x eval kit that you might have has different PHYs, so the SDK examples might not directly work with DP83TC814R PHY.
