nRF5 SDK v17.0.2: BLE Secure DFU Bootloader
This example requires one of the following SoftDevices: S112, S113, S132, S140 Important: Before you run this example, make sure to program the SoftDevice. The BLE Secure DFU Bootloader example uses the Bootloader and DFU modules to implement a bootloader

3-3> 앱 이미지 만들기 && 다운로드
: 만들어진 앱의 Hex 파일에 사인을 한후 dfu package를 생성합니다.
app_name.hex 및 private.key 를 가지고 있으면 nrfutil 을 사용해 zip 파일을 만들수 있습니다.
app_name.hex : 앱 빌드후 생성되는 hex 파일
private.key : secure bootloader 이미지 빌드시 사용한 dfu_public_key.c 파일의 짝이되는 private.key
>> nrfutil 명령어 예제
nrfutil pkg generate --hw-version 52 --application-version 2 ^
--application app_name.hex ^
--sd-req 0x101 --key-file private.key app_dfu_package.zip
3-4> app_dfu_package.zip 다운로드
▶ 디바이스 dfu 모드 진입시키기
:dfu 모드 버튼을 누르고 리셋
▶ 스마트폰 DFU 프로그램 실행
▶ 파일 선택하기
▶ DfuTarg 디바이스 스캔하기
▶ 업그레이드 시작및 상태 체킹하기
▶ "Completed " 메시지 확인하기
▶ 펌웨어 정상동작 확인
: 다운로드한 앱이 실행이 되는지 DFU 모드 재진입 등등 알아서 체킹
3-5> 통합 이미지 만들기
: 통합이미지를 만들어 nRF Programmer를 사용해 한번에 전부 Write 해 보겠습니다.

▶ 아래처럼 파일이 생성이 되면 OK
: sd_bl_app_settings.hex 만 nRF Programmer 로 Write 하면 됩니다.

E> button DFU 동작 테스트
: Button4 를 이용한 DFU 모드 진입 테스트를 위해 dfu_enter_check() 함수를 고쳐야 합니다.
#if 0 로 막힌부분은 앱이 존재하고 valid 한지 체킹하는 부분인데 button 테스트를 위해
잠시 막고 추후 릴리즈시 원상복귀 하시면 됩니다.
>> .\nRF5_SDK\components\libraries\bootloader\nrf_bootload.c
static bool dfu_enter_check(void)
{
#if 0
if (!app_is_valid(crc_on_valid_app_required()))
{
NRF_LOG_DEBUG("DFU mode because app is not valid.");
return true;
}
#endif
~~~~ 중략 ~~~~
}
▶ Button4 (P0.16) 에서 Button3 (P0.15) 으로 변경하기
sdk_config.h 파일만 다음처럼 변경하면 됩니다.
#define NRF_BL_DFU_ENTER_METHOD_BUTTON_PIN 15 //16
▶ Default LOW 일때 DFU 모드로 진입 했는데 HIGH 일때 DFU 진입하게 변경하기
static void dfu_enter_button_init(void)
{
nrf_gpio_cfg_sense_input(NRF_BL_DFU_ENTER_METHOD_BUTTON_PIN,
GPIO_PIN_CNF_PULL_Pulldown,
NRF_GPIO_PIN_SENSE_HIGH);

~~~~ 중략 ~~~~
if (NRF_BL_DFU_ENTER_METHOD_BUTTON &&

{
NRF_LOG_DEBUG("DFU mode requested via button.");
return true;
}
~~~~ 중략 ~~~~
}
그럼 수고하세요.
