Hello! I've tried really hard to do my homework on this issue, and while I found a lot of similar issues I haven't been able to figure out just how it applies to my configuration and project.
I am starting from a point where I have MCUBoot + SMP DFU working (with two images slots), along with a static NVS partition set up in `pm_static.yml'. I believe the partition manager handles allocating the rest of the space. I have a `child_image/mcuboot.conf' that is being recognized as well. I am using an NRF52 DK / nrf52832.
I added the following to child_image/mcuboot.conf to attempt to enable image signing (the partition size was there already and working fine).
# Set minimum 0x1000 aligned size CONFIG_PM_PARTITION_SIZE_MCUBOOT=0x8000 # Enable bootloader signature CONFIG_BOOT_SIGNATURE_TYPE_ECDSA_P256=y CONFIG_PCD=y
Based on this ticket ( CMake warning: Using default MCUBoot key, it should not be used for production.) I added the following to my app CMakeLists
# Configure MCUBOOT key location
set(mcuboot_key_file ${CMAKE_CURRENT_LIST_DIR}/ssum_sign.pem)
set(mcuboot_CONFIG_BOOT_SIGNATURE_KEY_FILE "\"${mcuboot_key_file}\"")
The above appears to work, since this appears in my build output:
MCUBoot bootloader key file: /*******************************/app/ssum_sign.pem -- Configuring done -- Generating done -- Build files have been written to: /*******************************/app/build_release/mcuboot === child image mcuboot - end ===
When I run a build after adding the above, I get the following error:
=== child image mcuboot - end ===

I have read through a lot of other tickets. These in particular seemed relevant but I wasn't able to resolve my issue with any of them
Exact error -> nRF Connect SDK 2.3.0: Partition Manager Fails with thingy91_nrf9160_ns board but they were using TFM, which is not applicable to my build
Related to application - MCUBoot private key on nrf5340dk
For kicks, I did take the partition.yml file generated before making these changes and try to stick it in pm_static.yml, but I ended up with the same error.
Thank you!
