I managed to setup a Demo App on the base on zephyr that uses MCUBoot as bootloader in multi image build, using the nRF Connect SDK.
Upload via SMP DFU with mcumgr is working.
But I would like to use nrfutil dfu protocol via serial/uart. I found several CONFIG flags but none worked for me.
Any suggestions what CONFIG is missing or did I need to choose a other bootloader, the open_bootloader?
I'm using the nRF52 DK (PCA10040), nrf52dk_nrf52832.
I used this MCUBoot config child_image/mcuboot.conf
Kind regards,
Matthias
