【首发？】Mac M1 编译原生toolchain以及配置烧录支持

（说明：按流程Intel Mac应该同理，因为烧录的binary是x86架构）
前提：
你已经按Linux的新手教程准备好了AiPi-Open-Kits目录，步骤到 ". install.sh", 不要执行 ". export.sh"，

游客，如果您要查看本帖隐藏内容请回复

首先按照Mac toolchain编译教程编译好toolchain，需要拉取7-8G的代码，编译比较快，总共耗时大概数小时，教程地址：

1. https://github.com/p4ddy1/pine_ox64/blob/main/build_toolchain_macos.md

复制代码

编译完成后，你将得到 /opt/riscv-toolchain/xuantie 下 890MB左右的toolchain，此时还不能直接编译，切换到 "AiPi-Open-Kits" 目录下

修改1:

1. # 文件 aithinker_Ai-M6X_SDK/cmake/bflb_flash.cmake 替换ubuntu为macos
   

复制代码

if(MINGW OR CYGWIN OR WIN32)
set(TOOL_SUFFIX ".exe")
elseif(UNIX)
set(TOOL_SUFFIX "-macos")
endif()

修改2:

1. # aithinker_Ai-M6X_SDK/export.sh 全部替换

复制代码

export PATH=$PATH:/opt/riscv-toolchain/xuantie/bin
export PATH=$(brew --prefix)/opt/coreutils/libexec/gnubinPATH

export PATH=$PATHPWD/toolchain/bin
echo $PATH
riscv64-unknown-elf-gcc -v
chmod 755 $PWD/tools/cmake/bin/cmake
chmod 755 $PWD/tools/bflb_tools/bouffalo_flash_cube/BLFlashCommand-macos
chmod 755 $PWD/tools/bflb_tools/bflb_fw_post_proc/bflb_fw_post_proc-macos

笑脸表情是 : $ 去掉空格
最后，执行 ". export.sh" 你的编译环境已经就绪，此时切换到helloworld, 执行下面命令即可编译&烧录

1. make flash COMX=/dev/tty.usbserial-2130
   

复制代码

11.22 更新：
上传了预编译版本,因为整体超过100M不支持上传，拆分2个包，解压后自行合并，目录结构参考

bflb_flash.cmake  bin  export.sh  include  lib        libexec  riscv64-unknown-elf  share

需要额外编辑的2个文件（bflb_flash.cmake 、export.sh）也放在这个包里，自行替换AiPi-Open-Kits里的同名文件即可

这个toolchain默认需要放在 /opt/riscv-toolchain/xuantie 下（因为export.sh里是指向这个路径），理论也可以替换AiPi-Open-Kits/aithinker_Ai-M6X_SDK/toolchain 目录，这样export.sh 手工编辑时就不用修改PATH相关信息，自行决定

学习

我的是编译环境是刷了linux的小米手机，架构是aarch64，试试看看能不能用

学习一下

export PATH=$(brew --prefix)/opt/coreutils/libexec/gnubinPATH
这个是安装什么？

在helloword 里执行报错：
CMake Error at /Users/master/Documents/Electronic_Fever/MCU/aipi/AiPi-Open-Kits/aithinker_Ai-M6X_SDK/cmake/bouffalo_sdk-config.cmake:31 (enable_language):
  The CMAKE_C_COMPILER:

    riscv64-unknown-elf-gcc

  is not a full path and was not found in the PATH.

  Tell CMake where to find the compiler by setting either the environment
  variable "CC" or the CMake cache entry CMAKE_C_COMPILER to the full path to
  the compiler, or to the compiler name if it is in the PATH.
Call Stack (most recent call first):
  CMakeLists.txt:5 (find_package)

编译toolchain报错日志很长，我截取最后的几行，大佬看看：

/bin/sh: line 4: riscv64-unknown-elf-ar: co ...

你这个大概率代码没拉完整，我前面全新环境重新编译了一下，代码目录含.git共有9G多，或者你用我编译好的吧，我编辑到主贴里

秀儿，编译结果发蓝奏云，懒得编译

等我脱敏重新编译一份吧
