SDRAM problem in SOPC builder

Thanks!! my SDRAM finally works now.

I was using SDRAM to store .bss, .heap, .stack, and etc.. i found this when i navigate to the linker in the BSP editor.

Then i changed them to SRAM, and everything works now. Except the SDRAM passed the DMA test, which i find it very strange. I did not include any DMA core that involves SDRAM, so how can it passed the DMA test?

I used the memory test template code provided in Eclipse.
