mcuboot customer config

Question

Hi, 
 I want to disable the UART of MCUBOOT to reduce power consumption. I searched in the DevZone and got the answer as below. 
 
 I followed the answer above, and created a test project based on the sample that zephyr/samples/hello_world. 
 The modification as below. 
 prj,conf 
 CONFIG_USE_SEGGER_RTT=y
CONFIG_RTT_CONSOLE=y
CONFIG_UART_CONSOLE=n
CONFIG_SERIAL=n

CONFIG_BOOTLOADER_MCUBOOT=y 
 CMakeLists.txt 
 # SPDX-License-Identifier: Apache-2.0

cmake_minimum_required(VERSION 3.20.0)

set(mcuboot_CONF_FILE prj.conf ${CMAKE_CURRENT_LIST_DIR}/mcuboot.conf)
find_package(Zephyr REQUIRED HINTS $ENV{ZEPHYR_BASE})
project(hello_world)

target_sources(app PRIVATE src/main.c)
 
 nrf5340dk_nrf5340_cpuapp.overlay 
 &uart0 {
 status = "disabled"; 
};
 
 mcuboot.conf 
 CONFIG_SERIAL=n
CONFIG_UART_CONSOLE=n 
 project directory

But I got a build error. According to the build log, "file STRINGS file "D:/NCS/v1.7.1/nrf/modules/mcuboot/prj.conf" cannot be read." 
 There is not any prj.conf file in "NCS/v1.7.1/nrf/modules/mcuboot/" actually. 
 Am I missing something?

Hi Simon, 
 Simon said: Could you try the following in the meantime: 
 Fullscreen 1 set(mcuboot_CONFIG_SERIAL n) XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX set(mcuboot_CONFIG_SERIAL n)

Thanks, It works.

rf\modules\mcuboot\CMakeLists.txt:187 (file): file STRINGS file "D:/NCS/v1.7.1/nrf/modules/mcuboot/prj.conf" cannot be read. 
 I found a workaround that create an empty pri.conf file in " v1.7.1/nrf/modules/mcuboot/".
