You will have to whip up a set of UPM words specific for you SDRAM. Wolfgang told me this a million times before I finally got my SDRAM working. Look at your SDRAM datasheet and you should be able to figure out the timing.
Also, there is utility from Motorola `MCUinit 3.1` that has a GUI interface to whip out all the timing for you memory controller. Search for it in google and you should be able to download it. Navin.

But this UPM table dosen't seem to work with my DIMM. Probably not. The whole initialization depends on the actual chip types; it's Micron SDRAM in our case.
