Nordic nRF5 SDK编译micro-ecc时报错处理

1. 运行build_all.bat提示路径不对。

D:\Download\tools\Nordic\52840\nRF5_SDK_16.0.0_98a08e2\external\micro-ecc>build_all.bat
process_begin: CreateProcess(NULL, "C:/Program Files (x86)/GNU Tools ARM Embedded/7 2018-q2-update/bin/arm-none-eabi-gcc" --version, ...) failed.
Cannot find: 'C:/Program Files (x86)/GNU Tools ARM Embedded/7 2018-q2-update/bin/arm-none-eabi-gcc'.
Please set values in: "D:/Download/tools/Nordic/52840/nRF5_SDK_16.0.0_98a08e2/components/toolchain/gcc/Makefile.windows"
according to the actual configuration of your system.

2. 一般是GNU Toolchain版本不同，确认下具体路径，如图是C:\Program Files (x86)\GNU Arm Embedded Toolchain\10 2021.07。
   
3. 修改./components/toolchain/gcc/下的Makefile.windows文件里的GNU_INSTALL_ROOT，如下。

GNU_INSTALL_ROOT := C:/Program Files (x86)/GNU Arm Embedded Toolchain/10 2021.07/bin/
GNU_VERSION := 10.3
GNU_PREFIX := arm-none-eabi

4. 重新运行build_all.bat。
