question about sdram on nios II

After I finished my project and built it ,there is no any error or warning.But when I run my C project,it said :

"Using cable "ByteBlasterII [LPT1]", device 1, instance 0x00

Processor is already paused

Reading System ID at address 0x00000010: verified

Initializing CPU cache (if present)

OK

Downloading 02000000 ( 0%)

Downloaded 8KB in 0.2s (40.0KB/s)

Verifying 02000000 ( 0%)

Verify failed between address 0x2000000 and 0x2001EEB

Leaving target processor paused."

I use sdram as my only storage.Is it my project so large?I hope somebody help me to solve this problem.Thanks!!

    have you checked the phase settings of your sdram clock ?

    there are plenty of threads on the nios forum about the sdram and nios II, what you could check.

    quartus will never give you a warning if your phase settings are not correct for your design. only if it can't archieve your timing settings ...
