[nrf52][SDK17] 如何使用官方BootLoader

所需檔案已經編譯完畢，直接放入指定目錄。

**\nRF5_SDK_17.0.2_d674dde\external\micro-ecc

​​micro-ecc.rar​​

BootLoader工程位置

xx\nRF5_SDK_17.0.2_d674dde\examples\dfu\secure_bootloader

使用keil編譯完成後，直接燒錄，是無法運作的，因為[mbr_nrf52_2.4.1_mbr.hex]引導檔案沒有燒錄。

xx\nRF5_SDK_17.0.2_d674dde\components\softdevice\mbr\hex\mbr_nrf52_2.4.1_mbr.hex

将檔案複制到工程根目錄

寫一個腳本，命名[program.bat]

@echo off

@echo eraseall
nrfjprog --eraseall

@echo program  boot.hex
nrfjprog --program .\out\nrf52_boot_usb_dfu.hex --verify

@echo program mbr_nrf52_2.4.1_mbr.hex
nrfjprog --program .\mbr_nrf52_2.4.1_mbr.hex --verify

@echo reset chip
nrfjprog --reset      

1. 生成settings檔案
2. 合并3個hex檔案(boot+settings+app)
3. 擦除晶片
4. 燒錄合并檔案
5. 燒錄mbr_nrf52_2.4.1_mbr.hex
6. 複位晶片

@echo off
set app_hex=%1
set nrf_tool_path=..\..\..\..\tool\nrf_tool\nrf-command-line-tools

@echo merge file

@echo eraseall
