Dears

I am using the BQ27426 EVM, after some change, I would like to reset the firmware as the initial one. I am tried to find the firmware on TI.com, but seemed there do not have.

So is there some suggestion how could me reset the firmware, or where could me find a initial firmware?

Thanks for the help

    Hello Jun

    The bq27426 firmware is not progammable. It has OTP memory for settings only. Before programming OTP , you can write the same values to RAM and test.

    "Import default" in bqStudio Data Memory is useful to restore to default settings.

    A power cycle will also erase any values written to RAM and cause initialization from default unless OTP was already programmed.
