We have some example C code to program gm.fs file.

See the app note below.

In the provided document, there is an example to update one data class at a time but i want to dump the whole golden file .gm.fs means i want to update the whole data memory at a time by dumping the golden file from my MCU to BQ27441. Is there any other example if you can share with me?

You can make use of the function gauge_execute_fs() to download a gm.fs file to a gauge device. Make sure you read through the entire app note.

golden file dumping is done. now i want to change the CC Gain because golden don't contains this parameter. In data sheet it is mentioned that calibration parameters don't require any customer changes. So can i change CC Gain?

You can add CC_Gain to the .gm.fs from bqStudio by opening Window->Preferences->Golden Image and removing the Calibration class from "Class Names to be Preserved in GMFS File".
