BQ35100: FW update

Part Number:BQ35100

Hi Team,

There are some FW update questions. please kindly help.

1. Do we need input default FW in BQ35100 after mounting on board?
2. Could we Calibration the non-FW board firstly, and then burn the Calibration FW into BQ35100 after?
3. If the default FW is need, now we use BQ studio and EV2400 to burn the FW. Any other way to burn the FW?

Thanks
