Hi,
We have designed a MPC8541 based card taking MPC8541CDS card as reference .
In our card we have provided marvell Gigabit Dual PHY chip "MV88E1121" on the
Tsec RGMII interface. We are using U-Boot as firmware . We have changed the
value of first two elements of structure "phy_info " from 0x01410c6 & "Marvell
88E1011S" to 0x01410cb & "Marvell 88E1121S"respectively in in tsec.c file.
These changes we have made as per the PHY identifier 1 & PHY identifier 2 from
the 88E1121 datasheet . With these changes U-boot is able to recognize our
Phy chip .
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.
we want to know what all changes are required in the U-Boot code to
initialize the PowerPC for RGMII operation.
Thanks & regards
M Ravi
