  • Hi,

    To extract the .df.fs file please navigate to the programming tab in BQstudio. 

    You will see 2 sections divided by gap, we are only concerned with the bottom section (3 boxes).

    In the bottom box, please select the path to original bq.fs file provided by TI that was flashed on to your device.

    In the top box please select the path where you want the DATAFLASH ONLY file to save and name the file accordingly.

    In the top box please select the path where you want the bq.fs that contains BOTH the DATAFLASH AND FIRMWARE to save and name the file accordingly.

  • Hello Diego,

    I am working on BQ41z50, which is also using .bq.fs file. Can I convert that file into. SREC format so, I can use my LabVIEW program for programming?

  • Hi,

    Our newer devices (BQ41z50) do not use .SRECs anymore. The equivalent file would be the bq.fs with the FW and Dataflash.
