Production programming of buttonless DFU images

[frankdunn]

We are upgrading some products to SDK 14.2 and creating some new ones.

We need to start production programming of boards.  I can't find the information on how to do this with regards to tricking the bootloader into accepting the preprogrammed image.

Prior SDK's had some trick.

Hi,

The secure bootloader requires more information to validate the app on startup compared to the legacy bootloader, so we've added an option in nrfutil to generate the settings page to simplify the process, see Generating and displaying bootloader settings.

After generating the settings page you can merge it with the bootloader, app and softdevice image to get a single .hex file (merge tool). 

Best regards,

Vidar

Thanks.  I must have looked there multiple times and missed it.
