Only one MDIO bus is exposed for accessing PHY registers due to CV SoC development board feature in a single chip of dual channel Mii PHY. The management of these PHYs is based on the access and modification of their various registers. As its name suggests the individual bits, or cells, of this register are at the boundary of the device, between its functional core and the pins or balls by which it is connected to a board - very often JTAG testing is referred to as. Customers need to make sure that above mentioned link stability issue is not seen in their setup before making this change. The ML4030-DCO supports the MDIO interface specified in IEEE802. Regarding the devmem2 tool, it can read the DM814x Ethernet subsystem registers, but it seams can not read the PHY registers, as these are external for the DM814x device and have some complexity for the read/write operations (see TRM MDIO).
