How to make LED blink when OTA upgrade

Dongdong Song

Hi, Team:

I want to make an LED blink during OTA upgrade and stop blinking after upgrade.

How do I configure prj.conf, sysbuild.conf, or provide some demos

Thank you.

    The CONFIG_MCUBOOT_INDICATION_LED option only light up an LED but won't blink.

    Blinking would require adding code to mcuboot. Can done with a module. That code can be triggered using CONFIG_MCUBOOT_ACTION_HOOKS calling mcuboot_status_change(mcuboot_status_type_t status) function that your module will need to implement.

    No idea if the default flash layout leaves enough room for this modification in the mcuboot partition.
