Hi there
I'm using Asset tracker v2 as a base for my application with AWS, however I wanted the FOTA to download to external flash, as the Asset tracker application is large, and leaves little room for any other application code.
I'm able to FOTA, to external SPI flash using MCUBoot, however once the download is complete I get an error
<err> dfu_target_mcuboot: boot_request_upgrade for image-0 error -14
Any help appreciated.
Here is the debug

The only files I had to add to the asset_tracker application were.
