I cannot get MCUBoot to create a image on external spi flash. Using the spi_flash sample I can read/write/erase fine with spi flash configuration in my device tree.
I am creating a child_image for mcuboot which contains mcuboot.conf and the board.overlay file.

Output:
I can't seem to understand why this configuration would work for the main program but mcuboot doesn't work.
I have tried almost every prj.conf, mcuboot.conf and pm_static.yml configurations I can think of with no luck.
Any ideas on what might be causing this? Changing CONFIG_BOOT_MAX_IMG_SECTORS doesn't seem to change anything.
Thanks for any help you can provide.
