Hi, After prog u-boot image to 8560. We get output as follows:
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
then it can't go on running. we checked ,found it falled in "relocate_code" ,then we write a progam to test memory, we found test failed(say write some thing to 0-0x8000000 then read)
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).
