Am335x with Marvell Ethernet Gigabit PHY

For anyone looking for an alternative PHY to the Atheros on the EVM. Elsewhere people seem to have got the Micrel part working.

We have successfully used the Marvell 88E1310 (88E1310-A0-NNB2C000) PHY with Halo Fastjack (HFJ11-1G01E-L12RL) Magnetics.

Route the GMII_TX and GMII_TXCLK the same length.

Route the GMII_RX and GMII_RXCLK the same length.

Adjust the timing in the PHY :-

In UBoot :-
 
mii write 0 16 3    ........ set page address to 3
mii write 0 10 1512 ........ set LEDs to board=TX, yellow=activity, green=link speed (3 flashes = 1000Mb/s)
mii write 0 16 2    ........ set page address to 2
mii write 0 15 1060 ........ turn off TX delay
mii write 0 16 0    ........ set page address to 0
mii write 0 0 9140  ........ apply software reset
boot                ........ boot over ethernet (must be connected to development PC)
