Hello,

    Sourabh,

    Have you programmed the passwords on this device? Instead of launching the project, launch the target configuration file and connect to CCS. After connecting, view the flash content via CCS memory watch window. If it's all 0x0 then device is locked and need to be unlocked to access it.

    Regards,

    Sourabh,

    After you connect to the device in CCS, go to View->Memory Browser.  Once this comes up you want to look type in address 0x3F7FF8 in the address box.  This will bring up the password locations on the device.  Click 'refresh in the toolbar", if these locations 0x3F7FF8-0x3F7FFF are all 0x0000 the the device has been locked.

    Let us know what you find.

    Best,
    Matthew
