data verification failed at 0x80000000.unable to access sdram

Hi all,

when iam trying to load a program on dsp processor,it is showing some error message " Data verification failed at 0x80000000". we suspect this problem is due to access to the SDRAM . Please let me know if we need to do something to make the external memories accessible(For example running GEL FILES).

In .cmd file i gave

MEMORY
{
        ON_CHIP   :      origin = 40200000h   length = 00010000h
        SDRAM      :      origin = 80000000h   length = 20000000h

}

SECTIONS
{
    .text       >       SDRAM      
    .stack      >       SDRAM      
    .bss        >       SDRAM      
    .cinit      >       SDRAM      
    .cio        >       SDRAM      
    .const      >       SDRAM      
    .data       >       SDRAM      
    .switch     >       SDRAM      
    .sysmem     >       SDRAM      
    .far        >       SDRAM     
}

after this i loaded the project the it is showing the following error message " DATA VERIFICATION FAILED AT 0X80000000".

please can anyone help me in this issue.

Thanks in advance

With regards

Pratap
