BQ40Z60:BQ40Z60 What data is recorded at 0010x0000...

Part Number: BQ40Z60
Other Parts Discussed in Thread: BQSTUDIO, BQ40Z50

Hi
We created *.srec file with the necessary settings.
How to write from the address 0000x4000 to 0x5FFF is understandable.
The file contains more data. Explain what is written and how to write data on the addresses 0010x0000…0010хDFFF (FFFF) and 0014х0000…0014x01FF

Thanks,

Anatoly

    I'm sorry, that's internal and we don't reveal that data.

    We want to record BQ40Z60 through the device microcontroller.
    How do we make a record in this case?

    The TRM describes the flash entry only at addresses 0x4000..0x5FFF.
    Is there really no need to write the rest of the software)?
    We need it for programming for Mass Production without EV2300.

    (If necessary I will send you our srec file and any other data)

    Hi Anatoly,

    Only the Data Flash needs to be programmed during production.

    The other areas are reserved for the firmware and device information, and it is recommended that those are left untouched.

    For programming the data flash, you can refer to the TRM section "0x4000-0x5FFF Data Flash Access()"

    One easy way to get the Data Flash data is using the Hex Dump feature in bqStudio (This is available when "Advanced mode" is enabled in bqStudio):

    Only the addresses exported in the hex dump are required for the programming, since some blocks at the end of the Data Flash address space are used by the firmware as a scratchpad.

    Also, the addresses exported by the hex dump are offset by the base address 0x4000.

    For further reference, this application note for bq40z50 is also applicable to bq40z60:

    Regards,

    Swami
