BQ78350-R1: Programming SREC File Using Custom Tools

Hello,

I'm developing a custom test system for programming and calibrating this fuel gauge. Can you provide documentation on how to write the SREC file? I'll need to know how to write the IF and DF portions, verify checksums, and use other commands while in ROM mode.

Thanks,
Jason

    Hi Jason,

    I can share a couple of options:

    - There is a firmware updater tool that will write an srec to the device.

    - I also have example code in Python I can share for writing an srec file to a device. This is an example only, not intended for production.

    I am sending both to you with some instructions in a private message.

    Best regards,

    Matt

    Hi Matt,

    Thanks for the files and example code. This will help a lot. I'll let you know I have any questions as I port this to my program.

    Thanks,
    Jason
