Hi,

Hi Ravi,

As per MPC8555ERM.pdf document TX_CLK for the PHY will be supplied by the powerPC in RGMII mode . In our case we are not getting this clock. We are not able to ping our board.

Be aware that u-boot has a "ping" command that you can use to ping *other* computers. U-boot does *NOT* respond to a ping from another computer (short explanation: u-boot is a simple polled mode program).

we want to know what all changes are required in the U-Boot code to initialize the PowerPC for RGMII operation.
