BQ20Z65-R1_BQEVSW-SW: BMS Firmware

Hi Adrian, 

Thanks for your response.  I provide some background for my problem in case you need.

We currently use BQ20Z655DBTR-R1 as the battery gauge and we have FW file golden_image_with_PETS_11A.dfi to program it.  Now the chip is switched to BQ20Z655DBTR.  The current .dfi file cannot be flashed to the chip.  So we need to update the .dfi file.  I don't know the .dfi is compiled in house or released by TI.  If you know how to build the dfi file, I very much like to learn.  If you have a pre-build dfi file, I would like to try to flash it to the new chip.

Thanks,

Hello Stuart,

I see, it is possible that the new file I can send to you will work. Accept my friend request and I can private message you that file.

I have not seen your friend request.  Could you send me the link?

Thanks.

Hello Stuart,

Can you hover you mouse over my name and press the "request friendship" button.

I just clicked the button "Accept friend request" when mouse over your name.  Sorry, I did not know the feature before.

Hi Adrian,

I have no experience to use TI tools to make dfi file.  Based on the document, BQEVSW should be used.  Could you walk me through the process to make the dfi file?

Thanks. 

Hello Stuart,

Please look over this link: https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/628479/bq20z655-r1-default-dfi

I am not familiar with BQEVSW but there should be a section in the GUI that can export the dfi file.

Regards,

Adrian
