CC1314R10: CAN I reflash without flashing the ccfg area?

Gullik Webjorn

Part Number: CC1314R10

Tool/software:

If i flash using jtag from CCS I get both code and ccfg.

If I reflash with a subsequent image, that has identical CCFG parameters, can I ommit flashing the CCFG, or is there something that prevents this?

I understand the image start of vector adresses is stored in ccfg, but not the start address itself, so if that is not

modified with a firmware upgrade that should work ???

Bulk erase should of course be avoided, since that erases CCFG as well, right??

Is there a serial programmer that can be customer installed and used to flash CC1314 ( via its serial porrt)?

    Hi Gullik,

    yes, you can use the ROM Bootloader to write a new image using UART.
    The procedure is explained here: https://www.ti.com/lit/swra466 and you'll also find a download link for an example.

    Kind regards,
    Theo

    Thanks Theo,

    My understanding is then as follows....

    1) produce binary file from the "flash" section of the compiled image.

       (the CCFG part can be discarded if I did not change anything with syscfg )

    2) programming each flash sector by erasing / programming (similar to existing tools)

      using only the "flash" section.

    3) computing checksum to verify programming

    This would boot properly, IF the CCFG paramerters were not changed for this version / firmware update.

    Regards,

    Gullik
