    Have you tried with the bq2085 EVSW?

    There is no need to program the whole senc file. Just a .dfi or .rom file is sufficient. Is there a specific reason to program the whole senc file?

    Hi Shirish,

    thanks for your answer.

    How can I generate a *.dfi or a *.rom. I know these files only from bq20z95 or 20z65 with
    the the bq Evaluation Software (http://www.ti.com/tool/BQ20Z65-R1_BQEVSW-SW).
    For the bq2085 I have to use the bqEVSW, isn´t it? Where can I read back a *.dfi?

    Is there a other EVSW for the bq2085?

    The reason why I do this is because I want to understand the bq2085 better. We have some old products that may need a cell change.

    Thanks for helping us.

    Hello Klaus,

    I think there is a flashstream app note on ti.com you can use for this part to convert senc to dfi or rom.

    Hi Klaus,

    The bq2083 evaluation software does not support *.dfi or *.rom

    It may also not support *.senc, but i am not sure.

    srec/senc files are normally used to program memory. The bq2085 srec/senc file is not referenced in any document or guide that TI provided for the bq2085. The other thread where the senc was posted for bq2085 was probably for a specific use case, is of unknown origin, and we discourage its use.

    The bq2085 comes preprogrammed with default data. Refer page 38 and 39 of the Datasheet (Memory map section)for information related to the programmable memory.  The Data Flash screen of the evaluation software has all the functions to modify this memory.
