stm32g491 flash dual bank support

Hi,
I’m currently working on the STM32G491 series MCU. Our requirement is to support OTA firmware upgrades. In case the flashing process fails, the system should automatically revert to the previous firmware.

Does the STM32G491 support this feature by default, or do I need to implement a custom bootloader to handle the fallback mechanism?

You will need to implement your own solution. The system bootloader does not support a fallback mechanism.

You can also look at OpenBootloader to see if it meets your needs.
