Power Fail during writing to flash

[surabi_k]

On the Traveo II (CYT2BL) which has the dual bank of code flash, during the flash write if power fails the code flash bank will be corrupt. 

Can this bank be used for future updates by erasing the contents

Hi @surabi_k 

Yes, the flash state will be unknown if reset or power-down occurs during program/erase operation, so it is recommended to erase the area because it may contain garbage data.
