Using nrfutil to generate a package from a merged hex

[nrbrook]

When using `nrfutil settings generate` to generate bootloader settings and merging with soft device and App, how do you then use `nrfutil pkg generate` to generate a package – what option do you use to pass the merged hex? Do you need to pass all the same options again as when using settings generate, or does it pull the settings out the bootloader settings?

nrfutil does not support "package generate" with merged images so you need to provide a separate hex file for the app, Softdevice, and bootloader.  Also, as you may know, the settings page is only needed when you program sd+bl+app through the debug interface as a way to manually validate the app for bootloader. The settings page cannot be included in a DFU image.

The options are similar, but not identical. You should also make sure to bump the version number as the bootloader will reject downgrades by default.
