BQ34Z100-G1: Is it possible to flash the Golden image via I2C using a host Micro controller, without the need to use BQStudio?

Part Number: BQ34Z100-G1
Other Parts Discussed in Thread: BQSTUDIO, EV2400

Is it possible to flash the .srec "Golden Image" file  to the BQ34Z100-G1 using a host Microntroller via the I2C connection?

At present we are required to connect to the BQ34Z100-G1 via an EV2400 tool using Battery Management Studio/BQStudio software in order to flash the image.

We would like to simplify the production process of our BMS and get the Microcontroller to flash the BQ34Z100-G1.

Is this possible, or is the BQStudio software a fundamental requirement of the process?

    hI Dan,
    Yes it is possible. You will need to use the flashstream format. Go to the golden image tab of bqstudio and you will see the option to extract a dffs or bqfs file. The bqfs contains the instruction flash and data flash. The dffs contains only the data flash. You can use either or, but the dffs will save you time as it contains less data.

    To program the flashstream files using your host uC, pls reference attached app note.
