Hi,
I am using a Custom processor board to run DP83865 and the board is working fine right now. Now I am working on the new revision of the board in which I plan to have old board + PHY on motherboard and planning to have a daughter card with another processor on it and I would like to see if I can share the RGMII interface between two processor to the single PHY chip with 0 ohms DNI between the old processor and PHY chip. If it is not possible then can I have the branching on the analog side of the PHY chip. i.e. Twisted pair of the signals between PHY chip and the RJ45 connector. The whole idea is to able to test the another processor and related circuit with out having much to change in the design.
