Yup, thought so. ;-) > My SDRAM is a Micron MT48LC16M16A2.

The SDRAM init sequence is odd, but hard to get wrong because it is invariant and there are plenty of working examples. > My PSDMR values have been given by another product using exactly the same > board and same HWCR configuration (PLD). But I will check them again. That is the critical issue: the PSDMR values. If all else fails, read the part number off a chip that is on your board and download the datasheet for *that* *exact* part number. Sometimes manufacturers upgrade their parts or hardware makes a "compatible" substitution and the timing is different.
