Hello Nordicsemi community,
1) manual build of mcuboot - When trying to build the mcuboot for nrf5340 via the mcuboot/samples/zephyr via the west build command, the build fails with a missing header file pm_config.h.
It seems related to the pcd dfu.

ninja: build stopped: subcommand failed.
2) config enabled mcuboot - If I do not build the mcuboot manually and just enable the CONFIG_BOOTLOADER_MCUBOOT=y in a sample projects prj.conf, the child image for mcuboot seems to build fine. After the flash, the app crashes, I either suspect the app image is not signed with the mcuboot root key, or the mcuboot image itself is incorrect.

Ideally I would like to be able to build the mcuboot manually and flash it onto the board prior to the primary image being flashed. (only building the mcuboot once)
Thank you for your support
