BQ27425-G2B: BQ27425-G2B / .gm.fs file programming error

Part Number: BQ27425-G2B
Other Parts Discussed in Thread: BQSTUDIO

Hi,

The customer is programming attached .gm.fs file at production line but they sometimes see programming error so I'd like to request you to check if there is issue in attached .gm.fs file. It's just exported from bqStudio so I think it should be no issue, but please check it just in case.

    Hi Satoshi,
    I would suggest using bqstudio to break up those long bytes. Make sure it line of commands is less than 32 bytes as this has been known to cause issues.
    thanks

    Hi Onyx,

    I'm creating golden image by using bqStudio. I can't find the setting to break up the bytes, but I understand that the red font below is the information of register and it's less than 32 bytes. So I think this golden image has no issue. Is my understanding correct?

    Hi Satoshi,

    Does your bqstudio have the options button as shown below when trying to extract your gmfs.? if it doesn't then it means it is the tool doesn't have that option included for the bq27425.

    The entire byte including the the commands should be less than 32. If bqstudio doesn't have that functionality, then  you would want to try doing it manually.

    thanks
