Program is slow in SDRAM

Started by Saeed Shahhoseiny April 16, 2008
Hi all

I am using a DM640 based board.
when I run my simple program(LED Blink) in SDRAM(MT48LC4M32B2 16Mbyte) it is around 100 times slower than when in internal SRAM(l2 cache).
(the amount 100 is gathered with the aid of oscilloscope)

can anyone guide me where is the fault? some parts of my real program(ndk_1_92_eval) need to run in SDRAM.

thanks in advance.
regards
