There are two 16M x 16 SDRAM connect to the LPC3250 as a 32bit wide SDRAM.

I get some problems when accessing the SDRAM.

When write:

UNS_32 *p = (UNS_32 *)0x83FC0000;

*p = 0xE59F002C;

Then read from p and p+4, and the result is 0xE59FE59F, 0x002C002C respectively.

I cannot figure out what is wrong.
