Nios II Verify Failed problem

Hi, I'm new on Nios II. Yesterday I made a led running project, and when I debugged, it didn't work well,and I found this:

Verifying 00001000 ( 0%)Verify failed between address 0x1000 and 0x18B3Leaving target processor paused

I don't know what is wrong and former page here says maybe something's wrong with the ram, so I check system.h,here are my onchip mem:

# define ONCHIP_MEM_NAME "/dev/onchip_mem"# define ONCHIP_MEM_TYPE "altera_avalon_onchip_memory2"# define ONCHIP_MEM_BASE 0x00001000# define ONCHIP_MEM_SPAN 4096# define ONCHIP_MEM_ALLOW_MRAM_SIM_CONTENTS_ONLY_FILE 0# define ONCHIP_MEM_RAM_BLOCK_TYPE "M4K"# define ONCHIP_MEM_INIT_CONTENTS_FILE "onchip_mem"# define ONCHIP_MEM_NON_DEFAULT_INIT_FILE_ENABLED 0# define ONCHIP_MEM_GUI_RAM_BLOCK_TYPE "Automatic"# define ONCHIP_MEM_WRITEABLE 1# define ONCHIP_MEM_DUAL_PORT 0# define ONCHIP_MEM_SIZE_VALUE 4096# define ONCHIP_MEM_SIZE_MULTIPLE 1# define ONCHIP_MEM_USE_SHALLOW_MEM_BLOCKS 0# define ONCHIP_MEM_INIT_MEM_CONTENT 1# define ONCHIP_MEM_ALLOW_IN_SYSTEM_MEMORY_CONTENT_EDITOR 0# define ONCHIP_MEM_INSTANCE_ID "NONE"# define ONCHIP_MEM_READ_DURING_WRITE_MODE "DONT_CARE"# define ONCHIP_MEM_IGNORE_AUTO_BLOCK_TYPE_ASSIGNMENT 1# define ONCHIP_MEM_CONTENTS_INFO ""# define ALT_MODULE_CLASS_onchip_mem altera_avalon_onchip_memory2

Can any one help me? Thank you!

    Only thing that comes to mind is that your design may not be meeting timing requirements. Have you properly constrained your Quartus design?

    I had a similar problem in a situation when I moved from sdram to sram the exception vector, which I think is made of those 0x8b4 bytes.

    Try opening sopc builder and change the setting in Nios processor properties.

    Anyway I couldn't investigate deeply the problem when it happened to me, so I hope some Guru will clarify this point, if this is really related to exception vector.

    Regards

    i used to have the same problem, but i used sram back then.

    it turned out that i forgot to update the block in Quartus, before i compiled it in the nios
