nRF Command Line Tools

用于对 nRF51, nRF52, nRF53 和 nRF91 系列芯片进行开发、编程和调试的工具。

安装过程中，不要去更改默认选项，直接按照默认选项去安装即可。 在安装完成后，可以打开命令行，键入如下命令，可以看到对 nrfjprog 和 mergehex 的相关使用说明

 nrfjprog --help 
 or mergehex --help

编译 & 烧录

解压 SDK 并编辑打开

GNU_INSTALL_ROOT := C:/Program Files (x86)/GNU Arm Embedded Toolchain/10
2021.10/bin/
GNU_VERSION := 10.3.1
GNU_PREFIX := arm-none-eabi

GNU_INSTALL_ROOT 将当前电脑交叉编译环境中的路径填充至此处 可在命令行中键入如下内容查看交叉编译环境的版本信息

arm-none-eabi-gcc --version

选择 examples/peripheral/blinky/pca10040/blank/armgcc ->在集成终端中打开

在终端中键入 make -j6，对 blinky 例程进行编译

在终端中键入 make erase，擦除芯片

makefile 实际执行

erase:
  nrfjprog -f nrf52 --eraseall

命令解释

 -e  --eraseall
Erases all user available program flash memory and
the UICR page. Can be combined with the --qspieraseall operation.
Limi tations:
For nRF51 devices, if the devicetcame from Nordic with a pre-programmed SoftDevice,
nonly the user available code flash and UICR wi11 beserased.

在终端中键入 make flash，将编译产生的 hex 文件烧录到 nRF5 开发板

makefile 实际执行

# Flash the program

flash: default

  @echo Flashing: $(OUTPUT_DIRECTORY)/nrf52832_xxaa.hex

  nrfjprog -f nrf52 --program $(OUTPUT_DIRECTORY)/nrf52832_xxaa.hex --sectorerase

  nrfjprog -f nrf52 --reset

命令解释：

-f  --family <family>       
Selects the device family for the operation.Valid
argument optionS are NRF51，NRF52,NRF53，NRF91，
and UNKNOWN.
If UNKNOwN familyis given,an automatic family
detection of the device is performed.Note that
providing the actual family is faster than
performingtheautomaticfamilydetection.If
-family option is not given, the default is taken
from nrfjprog.ini.Must becombined with another
command.

 --program <hex_file>
Programs the specified image_file into the device.
Supported file formats ares.hex,N.ihex,L.elf,
,axf，and.bin.
A valid format_must_be specified
by the filename extension.

--sectorerase is given, only the targeted
non-volatile memory pages excluding UICR wi11
be erased

nRF5 SDK有一个非常重要的配置文件：sdk_config.h ，可以通过 sdk_config.h文件对整个芯片软件架构配置， 使用make sdk_config命令，这个命令可以打开图形配置界面，需要有 java 运行环境
