Dear All,
We are using MPC8548E (Rev 2.1) with on-board ddr2 of 512Mbytes.
The DDR initialization hangs when the u-boot comes up. We see MSRCID [2] an input pin toggling.
The u-boot version is 2010.03 and DDR hangs by showing *** failed ***

The exact size is not printed by the u-boot. What could be the problem?
We went through the Register Configuration and also compared with register values of working board. Both match.
