BQ27542-G1: Creating Golden Image for bq27542-g1 and how to dump the golden image file using BQ Studio

Part Number: BQ27542-G1
Other Parts Discussed in Thread: BQSTUDIO

Hi Team,

We are using BQ27542-G1 fuel gauge. After completing the learning cycle which files do we need to use for creating the Golden Image from Golden Image Section. We are having three output formats. SREQ Files, BQFS Files and DFFS files. Which output format do we need to select ?

Another question is how we can dump the generated golden Image file using BQ Studio in our Fuel Gauge for production. 

Please help us as this is very urgent ?

Regards,

Mahek

    Hi Mahek,

    All of them are golden images. They can be used for different purposes.

    If you want to use bqStudio to program a gauge device, you would normally use a srec file.

    BQFS and DFFS files are used for mass productions. The difference is that DFFS only contains configurations while BQFS has both firmware and configurations.

    Hi Andy, 

    Thanks for your response.

    So for dumping the golden image using BQ Studio, we need to select srec file ? If yes, how to dump this file ? Do we need to use Programming section or Goldenizing section for selecting the srec file to dump golden image using BQ Studio ?

    Another question is if we want to dump the golden image using the code, we need to use dfss file only. Correct me if I am wrong ?

    Please reply as soon as possible.

    Regards,

    Mahek

    Hi Mahek,

    Go to Golden Image Windows if you want to generate a golden image.  The SREC, BQFS and DFFS files are all genreated there.  

    Use the dffs or bqfs file you want to use other tools or your microcontroller to program the gauge devices.

    See the app note below.

    Hi Andy,

    We are dumping the golden image using the bqstudio. In the Programming Section, I selected the srec files and programmed it by clicking on the Program button. Then I clicked on Execute FW button, during which it throws me the error "No acknowledge from device". What could be wrong here ? Is it necessary to click on "Execute FW" button after successfully programming. I am attaching the screen shot for this.

    Hi Mahek,

    Power off and then power on the gauge device. Relaunch the bqStudio and see whether bqStudio is still able to communicate the device that has been programmed.
