安装gcc-arm-none-eabi-10-2020-q4-major-win32工具(NRF52编译ECC加密文件用）

• gcc-arm-none-eabi-10-2020-q4-major-win32安装包下载

• 安装后环境变量配置

C:\Program Files (x86)\GNU Arm Embedded Toolchain\10 2020-q4-major\bin

• nrf52 SDK包工具链make文件修改（以SDK17.02为例，其它SDK方法一样)

1.  进入components\toolchain\gcc\目录下，右键Makefile.windows文件，选择打开方式使用记事本，将原来的内容

GNU_INSTALL_ROOT := C:/Program Files (x86)/GNU Tools ARM Embedded/9 2019-q4-major/bin/
GNU_VERSION := 9.2.1
GNU_PREFIX := arm-none-eabi

修改成如下

GNU_INSTALL_ROOT := C:/Program Files (x86)/GNU Arm Embedded Toolchain/10 2020-q4-major/bin/
GNU_VERSION := 10.2.1
GNU_PREFIX := arm-none-eabi

2. 保存并关闭，然后进入external\micro-ecc目录下，使用记事本打开build_all.bat,在最后面增加pause，保存关闭

@ECHO OFF

:: This script will use git (must be in %PATH%) and arm-none-eabi tools in combination with GNU Make
:: to both fetch and compile all variants of micro-ecc for the nRF5 families

WHERE >nul 2>nul git
IF %ERRORLEVEL% NEQ 0 (
    ECHO "git is not installed. Please install and append to PATH."
)

IF NOT EXIST micro-ecc/uECC.c (
    ECHO "micro-ecc not found! Let's pull it from HEAD."
    git clone https://github.com/kmackay/micro-ecc.git
)

make -C nrf51_armgcc/armgcc
make -C nrf51_iar/armgcc
make -C nrf51_keil/armgcc
make -C nrf52hf_armgcc/armgcc
make -C nrf52hf_iar/armgcc
make -C nrf52hf_keil/armgcc
make -C nrf52nf_armgcc/armgcc
make -C nrf52nf_iar/armgcc
make -C nrf52nf_keil/armgcc

pause

3.双击运行build_all.bat批处理(运行此文件前需要保持网络良好)

"micro-ecc not found! Let's pull it from HEAD."

请按任意键继续. . .

4.external\micro-ecc\nrf52nf_keil\armgcc目录生成了加密库，这个库给DFU工程用
