    Hi Arun,

    have you tried the nor_writer from Spectrum Digital?

    I tried that one to write to write  a program, where at the beginning it erases the memory first.

    http://support.spectrumdigital.com/boards/usbstk5515/reva/

    you can find under the Demo section. everything you need is inside the zip folder.

    Regards,

    Thanks to Vava for helping.

    Yes. Writing to NOR flash requires checking the device ID. C5515EVM and C5515 ezDSP use different kind of NOR flash. Refer to their schematic for details. What board are you using?

    Regards.
