Readback verify error with SDRAM

Hi all, I am working on an ARM board setup containing an ARM IM-LT3, IT1 and fou logic tiles, all used to emulate an ARM1176 based system. There is a external 128MB SDRAM connected to IM-LT3 board. All FPGAs are wel configured. After connecting to the setup through RealView ICE, when I tr to load any image at any SDRAM location (thru RVDebug), it gives followin error.

-----------

load/r 'C:\Peeyush1\Projects\MultiProcessing\Temp\vmlinux.elf'

Loading file C:\Peeyush1\Projects\MultiProcessing\Temp\vmlinux.elf... Error: Readback verify error in Program memory at S:0x26008000

-----------

SDRAM range is 0x20000000 to 0x2fffffff. The error remains same even afte removing SDRAM from its slot. Loading (and running) works fine if I try t load image in any other memory, for eg. 0x00008000 in internal ROM.

Any ideas? How to verify if this is a hardware problem or software one ?
