Power Quicc 3 problem HW/SW ??

Hi all, Our MPC8548E is having problems loading the DDR2 memory (boot) from the driver burned on the flash. The DDR interface and flash interface (LBC) were tested stand alone and found to be working properly. Errors accour only when writing the DDR from the flash and it happens (the error) at the same data sequence every time. When we changed the code a little bit and this data shifted to another address we got the same error at the same 64 bits of data with the address shift in the DDR.

I will be happy to know if you guys have any ideas ... Thanks, Moti.

Loading thread data ...

By driver, I assume you mean the boot loader?

DDR SDRAM is "fun" to configure. You need to read the SPD EEPROM and configure the DDR-SDRAMs accordingly.

You really haven't given us much to go on.

Have you run any RAM tests after configuring the controller and DDR-SDRAM?

Is the RAM test failing?

What is the "code" supposed to do?

What did you change?

What boot-loader are you using? u-boot?

Has it ever worked before?
