Chances are that the MPC8343 DDR controller is much the same as the MPC8349EA controller. Here's a couple of annotated BDI2000 configuration files for the MPC8349E-MDS-PB loaded with 2.5V DDR1, and the MPC8349EA-MDS-PB board loaded with 1.8V DDR2 ftp://www.denx.de/pub/BDI2000/mpc8349e_mds_pb.cfg ftp://www.denx.de/pub/BDI2000/mpc8349ea_mds_pb.cfg I'm not sure if it'll be of use, just wanted to mention it. The U-Boot code for the MPC8349 handles both board types transparently. I haven't delved into the code in too much detail, but I think the code is using the SPD EEPROM information to configure the controller appropriately for DDR1 or DDR2 operation. You can probably use that code as a reference to any changes required for your MPC8343 code. Regards, Dave
