+1. Pass `USE_EXTERNAL_FLASH=1` flag to `make` command when building MCUBootApp.
 2. Navigate to `cy_flash_map.c` and check if secondary slot start address and size meet the application's needs.
 3. Define which slave select is used for external memory on a board by setting `smif_id` value in `main.c`.
 4. Build MCUBootApp as described in `Readme.md`.
