I have a custom board I am trying to bring up that is a pretty close architecture to the Luan2 board. I have an unregistered 2GB DDR2 module in the DIMM slot, and it works fine using the BDI2000.
Did you ever try a smaller module. I would start with something like 256MB. Are you aware that the MMU has to be setup for this big memory module?
However, using the same DDR2 configuration in U-Boot doesn't work. It boots up until the point it transfers over to memory. I have enabled the memory test and it fails at the first address. I have verified all of the memory configuration registers, and all seem to be set correctly. I know there is something in the configuration I am missing, but I can't seem to figure it out. Please help. I would greatly appreciate it.
First try smaller modules. If they also don't work, you most likely have a problem with your DDR2 setup.
Best regards, Stefan
