TMS320F28388D: Run Ethernet Demo with a different PHY device

Part Number: TMS320F28388D
Other Parts Discussed in Thread: C2000WARE, TMDSCNCD28388D

Hi team,

I am supporting my customer who is trying to use F28388 but with a non-TI phy. 

With the follow schematic, customer tried to do a ping test but cannot succeed. Could you kindly help to check where requires modification(H/W and S/W)?

    Brian,

    There is a lot of intricate knowledge that will be specific to that Phy. The register locations, bootstrapping configuration, default address, even the data rate may all be different or need to be configured. All of these could keep the PHY from communicating.

    From a C2000 perspective, MII, RMII, and RevMII are supported,  by the look of the schematic MII is intended to be used. Please make sure the device is configured as such. The best schematic reference we have the TMDSCNCD28388D which the schematic files can be found in C2000Ware. This shows off how to connect a c2000 device to a TI PHY using an MII interface, so it should be quite similar to the connections needing to be made here.

    Regards,
    Cody
