bq27510 Firmware version check and programming using dffs

Hi All,

We are currently in production and the latter part of the production phase will have a mixture of bq27510-G2 and bq27510-G3 fuel gauges. We had generated golden file, bqfs and dffs for both the G2 and G3. We will be using dffs vis our custom USB to I2C kit

We have the basic algorithm for the Fuel Gauge Programming:

Enter ROM Mode -> check firmware version ->select correct dffs(G2 or G3) ->program FG (up to 10 attempts)->Exit ROM mode

Basically, these are my questions:

1. Are there any commands we need to insert before programming the FG with dffs?
2. How can we check the FW version if it is G2 or G3?

I can't find G2-G3 Change List in the website.

Thanks,

Kat
