如何在Makefile.posix中配置值以解决nRF52840 armgcc编译错误

执行make编译项目时出现如下错误：

su@su-desktop:~/nRF/nRF5_SDK_17.1.0_ddde560/examples/peripheral/template_project/pca10056/blank/armgcc$ make

修复步骤 #

• 打开SDK路径下的配置文件：/home/su/nRF/nRF5_SDK_17.1.0_ddde560/components/toolchain/gcc/Makefile.posix
• 修正以下三个核心变量：
  • GNU_INSTALL_ROOT：填写armgcc工具链的根目录（不要带末尾的bin/），比如你的工具链在/home/su/gcc-arm-none-eabi/，就设置为GNU_INSTALL_ROOT := /home/su/gcc-arm-none-eabi/
  • GNU_VERSION：执行arm-none-eabi-gcc --version查看版本号，填入对应值，比如GNU_VERSION := 10.3.1
  • GNU_PREFIX：保持arm-none-eabi不变，即GNU_PREFIX := arm-none-eabi
• 保存文件后重新运行make命令
