SDRAM read out of sync

I am testing SDRAM read and write using nios. I wrote a simple function with loops to write to 15 memory locations and read them back. for(i=min; i<max; i++) { IOWR(SDRAM_BASE,0,i...

pbase is a pointer to the DRAM base address and gets incremented every time to the next memory location in the loop.

# define SDRAM_BASE 0x00000000

void test()

{

pbase=(alt_u32 *) mem_base;

.

}

void main()

{

test(SDRAM_BASE, 0, 0x000000ff); //just testing the first ff memory locations

}
