With my recent port for the 8560 for our custom board we found that the
8560 does not work properly with some makes of DDR modules. Have you
tried some different RAM with your board?

Tell us a bit more about your RAM

Looks like the RAM is not set-up correctly at all - you will need to go
through the settings using the RAM data sheet and the 8560RM book. Make
sure the settings being derived by "spd_eeprom" are what you expect.

Also when you get it working with your RAM test you may still get
problems with your OS. We ended up having to hand pick RAM for this
processor with our board. I would be interested in seeing how you get on.

We have moved on to the the 8548 for our B-Model and I have had to make
changes to "spd_eeprom.c" to accommodate our RAM. I am hoping to provide
this back as a patch when I am sure it works OK with our OS (QNX).
