i am struggling to find right solution for pass this file into fuel gauge ic. because

i not get specific answer. i know my ic is flash based. i need to pass this file without bqstudio so i have to not use .srec fomat file.

so from bq,fs, gm.fs and df.fs  which file i need to choose for my flash based ic so that my ic not go into unrecoverable state due to enter into rom mode ?

i want to know exactly where this file get stored inside fuel gauge ic ?

    Hello,

    You will need to use the bq.fs or df.fs depending on if your gauge arrives with the correct firmware. bq.fs contains firmware and dataflash.

    ROM mode is recoverable, you can check other E2E threads.

    You should follow the SLUA801 for code examples to upload flash stream files with your own MCU.

    Sincerely,
