SK-AM64: MCU+ SDK for AM64x - ICSSG0 SMI not recognized

Part Number: SK-AM64

Hi,

For this example project, is there any additional configuration required to have ICSSG0 MDC/MDIO connect to external PHYs?

https://github.com/TexasInstruments/mcupsdk-core/tree/next/examples/networking/lwip/enet_lwip_icssg

I am using a daughter board with the MAC interface of DP83TG720 connected on J2 of TMDS64GPEVM.

After configuring sysconfig with the 720 PHY address and enabling ICSSG0, the project does not return any information about the PHY over MDC/MDIO:

When running the project with default settings on ICSSG1, the DP83869's model / PHY ID information is returned on the terminal.

I have verified SMI functionality is working on a separate project with the same HW, where the 720 registers are accessible.

Is it possible to have PHY information logged through MDIO/MDC on ICSSG0, similar to how the generic PHY driver is able to bind to DP83869 for ICSSG1 out-of-box?

Thank you,

Evan
