BQ40Z50-R2: bq40z50-R2 Gauging Embedded Firmware v2.08 - wrong ZIP file contents

Part Number: BQ40Z50-R2
Other Parts Discussed in Thread: BQSTUDIO, BQ40Z50

Hi,
We're making prototypes of new project, that have bq40z50-R2 onboard. bqStudio says, that Device ID is 4500_2_08. I suppose, that it's about 2.08 Firmware;

When I go to www.ti.com/.../toolssoftware , download bq40z50-R2 Gauging Embedded Firmware v2.08  (ZIP 4249 KB )   - and unZIP it, I find, that it contains 2.11 version of firmware.

Could you fix it, so that archive contains correct firmware, ASAP, please?

    Hi,

    Yes, there is an update to the firmware available and the next release of bqStudio will contain the updated version 2.11 file. For now, you can run the bq40z50 firmware updater which will update you to the latest firmware and populate the bqStudio config folder with the new bqz file.

    Best regards,
    Matt

    Hi,
    Thank you for fast answer.
    Unfortunately, after updating bqStudio with that file, IC auto-detection is working, however, GUI is not launching, and proposing to select device manually... is it ok? because on EVM, where there is -R1 version device, software automatically detects IC and launches GUI, where registers are visible.

    Hi Guy,
    After you run the bq40z50-R2 v2.11 installer, you will have a .srec file and a .bqz file. You need to put that .bqz file in this directory and relaunch bqStudio: C:\ti\BatteryManagementStudio\config
    Then you need to use the Firmware plugin in bqStudio to program the .srec file to your IC, which will upgrade it to v2.11 FW.
    Then when you relaunch bqStudio it should autodetect v2.11 is on your IC and launch with the right .bqz file automatically.

    Thank you, dMax - this helped to make GUI automatically detect device and open GUI!. :)
