All,
We are proceeding with the manufacturing of our product and initially, we had bq27510-G2 however, due to the time schedule and the availability of G2(out of stock) from our supplier, we had decided to procure G3 to avoid any delay. Our DFI file is based on G2.
In addition, we had created our own FG programming software using bqfs. However, the client would want to program using dffs if the firmware version is already correct in order to reduce tack time.
These are my main concerns:
1. How will we be able to check the firmware of the FG? Can we check the FG firmware without EV2300 and not using the bq evsw? Can we check the firmware by Write-Read-Compare (USB to I2C) to specific registers? If so, can anyone please provide us as to what App note we need to refer to or if anyone could give us direct assistance?
2. Can bq27510-G3 be downgraded to bq27510-G2 firmware? we had encountered issues before using G1 hardware upgraded to G2.. If G3 could be downgraded to G2, can we use bqfs file? what are the other parameters/checksums that we need to check?
Thanks,
Kat
