BQ78350-R1: Bqstudio missing 'Golden Image' and 'Programming' tabs

Pranith Michael92

Part Number: BQ78350-R1
Other Parts Discussed in Thread: EV2400, BQ76940EVM, BQSTUDIO

Hello,

I am using the latest BQ studio (Ver 1.3.80) to configure BQ78350-R1(gas gauge) present on the BQ79640EVM.The EVM is interfaced via EV2400.

I am trying to program the gas gauge with new configuration of cells, cell chemistry, capacities etc and save the setting to a .srec file.

All related posts on the forum refer to 'Golden image' and 'programming' tabs (plugins) that I don't see in this build of BQ studio.

I am referring to this post: https://e2e.ti.com/support/power_management/battery_management/f/180/t/489947

Setting window>preferences>global preference to 'show advanced views' does not bring up these tabs.

The same was observed with BQ studio Ver1.3.54 build.

Are the tabs supposed to appear for specific gauging ICs or am I not using the right BQ studio version?

Any pointers would be helpful.

Thank you

    Hi Pranith,

    Please click on reset perspective under the window menu to see if they get enabled.

    Hi Batt,

    Thank you for your advise. I reset the perspective.

    Though it brought out many tabs that were previously missing, I still don't see the 'Golden image' option in the tool bar. Moreover the GUI goes blank.

     

    Clicking on other options such as to view registers or data memory does not display any data and the GUI remains blank. 

    I restored the previous perspective hoping the newer options(tabs) would stay, but unfortunately it does not reflect the changes.

    Hi Pranith,

    I checked internally. This gauge doesn't support going to production via that route. You have to use df import with an unsealed gauge and then seal it after importing the parameters on your production line.

    Hi Batt,

    As per the datasheet, TI usually ships the unsealed gauge, in this case, its the gauge mounted on the BQ76940EVM.

    I plan to use a an external host (controller) to program the data flash of the gas gauge with the configuration I have on the EVM.

    The procedure that I presently plan to follow is:

    1. Configure/program the gas gauge on the EVM as per my hardware architecture 

    2. Export the CSV file that encapsulates the entire configuration of the gas gauge from Bqstudio.

    3. Use the host to program the values read from the CSV via SMBus commands and configure the gauge on my hardware.

    Is there a easier way to program the gauge using an external host?

    Are DF import and CSV file the same? If not, Could you please let me know of how I can go about exporting this file on Bqstudio.

    Thanks

    Hi Pranith,

    df import imports from a .gg.csv file. That is the default format of all exports of a gauge's dataflash storage. You can also do a hex file export which basically gives you addr: data format. That format is called a .gg file. For production purposes, you can choose to do either.
