BQ78350: Programming SREC from microcontroller or similar

Sam Bain

Part Number: BQ78350
Other Parts Discussed in Thread: BQSTUDIO

Hi there,

I am currently trying to find a way to program the BQ78350-R1A devices from an onboard companion microcontroller using the data gathered in an SREC file.

Any tools and examples shared would be extremely helpful.

Regards,

Sam

Hey Sam,

Please refer to this document regarding gauge communication. https://www.ti.com/lit/an/slua801/slua801.pdf

Hi Nick,

Thanks for sending that through. Unfortunately that document only specifies uploading firmware in the FlashStream format, which I believe isn't an option for exporting from this device (can only export srec file).

Other people have had similar issues in the past, like this one, and to solve the issue, Matt sent Phil a python file to write the srec file to the device. If I could get access to this python file, or if there is someway to output the firmware from bqstudio in the .bq.fs (FlashStream) format that would be great.

Cheers,

Sam

Hello,

Unfortunately, Matt does not work in this group anymore and we do not have his python program anymore.
