    Hi Gayathri,

    have you already checked http://processors.wiki.ti.com/index.php/Troubleshooting_CCS_-_Data_Verification_Errors ?

    Hope it helps,

    Does your program use the information memory locations? Have you checked the CCS download options (default is erasing main memory location only)? You have to erase the information memory too, before flashing new values.
