Dears,

I am using u-boot 1.2.0 for mpc8315e processor with BDI2000 debugger in a new design based on MPC8315ERDB. Our board has a different DDR2 and Flash memory. The flash memory works fine. The problem could be DDR2.

We are using Samsung K4T1G164QE DDR2 Memory. I can read/write DDR2 memory with BDI2000, but I have problems when u-boot try to write the first information in DDR2 memory (lib_ppc/board.c line 493 => *s-- = 0). After that, the program does not work.

There is a breakpoint in this line. After the breakpoint accours, I do a step command and I receive this message from gdb:

Program received signal SIGSTOP, Stopped (signal). 0x00001200 in ?? ()

It could be a problem with DDR2 configuration registers?

Thanks in advance,
