2] in production which communication i need to use  to write this golden image file in other bq27z561 ics ?

3] Is there any reference code is there for flash based gauge ic bq27z561 for write golden image file for production?

    Hello Mangal,

    There are multiple files you can use to program the gauge depending on your needs, the differences are explained in other posts on this forum.

    You can use your own MCU and programming system using the flash stream or EV2400 and bqStudio.

    You can reference our gauge communication app note: www.ti.com/.../slua801.pdf

    In above mentioned document at section 4 they told that

    " TI provides production tools (bqStudio and SmartFlash) to program flash or OTP memory during production. After the gauge configuration is completed during development using bqStudio and a gaugeEVM , bqStudio generates a Golden Image with the gauge configuration.TI production tools use this Golden Image file to program flash or OTP memory."

    what steps i need to follow  of bqstudio to program golden image file into  flash memory?

    Hello Mangal,

    That section is regarding OTP (One Time Programming) gauges, the bq27z561 is a flash based gauge, meaning it can be programmed many times.

    The bq.fs file and .srec files will contain the Instruction Flash (IF) and Data Flash (DF) so they are usually recommended. IF is the firmware.

    I can't specify for you, it depends on your capabilities and system. If all your gauges are already on the firmware you want, then the df.fs file might be faster for production. 

    Sincerely,
