Hello Nordic Team,
Over the course of development I have had to reverse engineer and pick apart various sources (DevZone, Google, Zephyr documentation, etc) in order to figure out how to properly generate and utilize a custom, private signing key for our FOTA images. I currently have a working solution but it feels more like a hack and as I frequently test on the master branch to prepare for upcoming changes, it appears that the method I am using is generating warnings.
My question is: is there any official documentation and/or guide on how to properly generate and sign images using a custom signing key and how that is integrated into a project (ie asset_tracker)?
I want to make sure that I am doing it right and that it is properly integrated into my project and build system.
Thanks,
Cody
