BQ34110: Flash programming robustness

$

Part Number:BQ34110

I'm designing a system with BQ34110 and external flash.

Update of firmware (*.bq.fs file) and data (*.df.fs file) is planned to be made with FlashStream Parser from a onboard IC.

Q1: What will happen if power interrupt occur during flash writing?

Will the BQ34110 restart in a boot-state, waiting to continue the programing session? How to detect?

Q2: What if transferred data is corrupted? I.e. one (or several) data block(s) transferred with NOK CRC.

How to detect and how to recover from a transfer of an corrupted file?
