Hello,
I've been having issues trying to add MCUBoot to our application. The app is based on the Common Application Framework (CAF) with a structure based on the nrf_desktop application.

So, following https://devzone.nordicsemi.com/guides/nrf-connect-sdk-guides/b/software/posts/device-firmware-update-dfu-with-mcuboot-bootloader and the documentation in https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/ug_multi_image.html#image-specific-variables I added a mcuboot.conf file in the child_image directory with
CMake Error at C:\ncs\v1.8.0\zephyr\cmake\extensions.cmake:2035 (if):
if given arguments:
"NOT" "EXISTS" "C:/ncs/v1.8.0/nrf/subsys/partition_manager/partition_manager_enabled.conf" "C:/Users/Mark/Documents/Projects/foobar/app/configuration/nrf52dk_nrf52832/child_image/mcuboot.conf"
Unknown arguments specified
Call Stack (most recent call first):
c:\Users\Mark\Documents\Projects\foobar\app\build_dk_mech_dbg\CMakeLists.txt:52 (assert_exists)
This is the build command:
west build --build-dir app/build_dk_dbg --board nrf52dk_nrf52832 --pristine --cmake-only app -- -DOVERLAY_CONFIG='C:/Users/User/Documents/Projects/foobar/app/configuration/_common/debug.conf' -DCONF_FILE='C:/Users/User/Documents/Projects/foobar/app/configuration/nrf52dk_nrf52832/prj_a.conf
I must say that I find the combination of the partition manager and configuration in child_image .conf files quite confusing. Any help is appreciated!
