Hey,
I have implemented BT FOTA process for my zephyr based application. DFU over Bluetooth works fine.
But now I struggle to implement manual upload of image (it will be done via spi in future).
What I'm trying to do?
I want to generate .hex or .bin file shifted to slot1 address space and flash this file via west to trigger mcuboot swap.
As far as I know, west build does not generate .hex file with shifted addresses that can trigger DFU procedure.
There is app_update.bin - it is working fine when i upload via bluetooth with NCS application. But i would like to upload this file via west,
then reboot my MCU and see that mcu boot swaps images - but this didn't happen for now 
I tried with all .hex files generated by west, I also translated app_update.bin to .hex with this tool:
arm-none-eabi-objcopy --change-addresses 0x3E000 -I binary -O ihex build/zephyr/app_update.bin app_update.hex
But flashing this hex via west also does not trigger swap and always old image is booted.
Maybe you guys are able to point what I am missing here. Official BT DFU was warking excellent, but my app has to handle OTA over interfaces not supported by zephyr.
This is why I have to implement manual upload.
Thanks!
