Part Number:BQ27421-G1
We used the TI BQ27421-G1A gauge ICs in our product.
And there are 2 F/W versions (0x0108 and 0x0109) of gauge ICs on the PCB.As now.
Q-1) If we remove the checking of F/W version in the line-6 and line-7 of the golden image (*.dffs file) directly,
could this modified golden image (*.dffs file) work on F/W versions (0x108 and 0x109) of gauge ICs?
1-1) About the line-6 and line-7 of the golden image (*.dffs file), please refer as follows:

Q1-2) Should we modify any other lines in the golden image to remove the checking of F/W version, like checksum and etc.?
2) About the content of the golden image (*.dffs file), please refer as follows:
