RE: Building MCUBoot in Segger IDE

I managed to program both the MCUboot and the application using SEGGER Embedded Studio (SES) Nordic Edition v4.52 (64-bit).

I added CONFIG_BOOTLOADER_MCUBOOT=y to ncs\zephyr\samples\basic\blinky\prj.conf and built it using SES: Build→Build zephyr/merged.hex. This will build both the mcuboot (ncs\zephyr\samples\basic\blinky\build_nrf52840dk_nrf52840\mcuboot\zephyr\zephyr.hex) and the blinky application (ncs\zephyr\samples\basic\blinky\build_nrf52840dk_nrf52840\zephyr\zephyr.hex) and merge the hex files into the file ncs\zephyr\samples\basic\blinky\build_nrf52840dk_nrf52840\zephyr\merged.hex.

If you've built the application as explained above, mcuboot and the application can be flashed in some different ways. Here are some options:

You can program the application and mcuboot separately by adding the files ncs\zephyr\samples\basic\blinky\build_nrf52840dk_nrf52840\zephyr\app_signed.hex and ncs\zephyr\samples\basic\blinky\build_nrf52840dk_nrf52840\mcuboot\zephyr\zephyr.hex to the nRF Connect for Desktop Programmer app and flashing it all to the chip
Flash merged.hex using the Programmer app
Flash merged.hex using SES
- In SES, click on Target→Download zephyr/merged.hex

Best regards,
