Hi Kuno,

By following the suggestions in this case you should be able to separate the building and flashing of the bootloader and application How to use a prebuilt (MCUBOOT)HEX file of the child image and include it with the parent image?

Let me know if the info in this case is enough to get you going, and if not I'll keep looking into it!

Kind regards,
Andreas

Thank you for your reply, Andreas.

I would like to control the version of the image for both the bootloader and application. When a product goes to production it will be flashed with a version of the bootloader and a version of the application.
But when a product is shipped, only the application should be needed to be upgraded and still work with the old bootloader.

Hi,

Could you expand a bit on your motivation for why you want to build the bootloader and application separately? Is it because you want to save time, flash only either the bootloader or the application or other?

I would recommend that you keep building the bootloader and application simultaneously as that ensures that signing of the images to proceed properly.

Kind regards,
Andreas
