本文详细介绍了如何在Windows平台上使用Cygwin搭建嵌入式开发环境，包括安装Cygwin、Toolchain及SDK，解决编译错误，并生成可烧写的镜像文件。

Windows平台搭建

1. 安装Cygwin工具

从Cygwin官方网站下载Cygwin终端setup-x86.exe
运行setup-x86.exe安装Cygwin工具包（注意：安装路径不要包含中文路径或者空格）
在安装包选项选择想要安装的工具包（cmake, git, wget, binutils， python, python-pip， zip, unzip, vim等）

Cygwin官方网站:

https://www.cygwin.com/

下载 setup-x86_64.exe

重新安装

再三安装

安装教程请参考

https://blog.youkuaiyun.com/chunleixiahe/article/details/55666792

下载 Toolchain: gcc-arm-none-eabi-4_9-2015q2

Windows 版本
https://launchpad.net/gcc-arm-embedded/4.9/4.9-2015-q2-update/+download/gcc-arm-none-eabi-4_9-2015q2-2
0150609-win32.zip

将 “ gcc-arm-none-eabi-4_9-2015q2-20150609-win32.zip ” 解压至 Cygwin 的
“~/tools/gcc-arm-none-eabi-4_9-2015q2” 目录（若“tools” 目录不存在，则需先创建）。

我存放的地址是

C:\cygwin64\home\xradiotech\tools\gcc-arm-none-eabi-4_9-2015q2

以上操作完成 Windows 环境下 Toolchain 的安装，且 Toolchain 安装目录与“[sdk]/gcc.mk” 中的“CC_DIR”
变量一致（[sdk]表示 SDK 根目录）。
CC_DIR = ~/tools/gcc-arm-none-eabi-4_9-2015q2/bin

鉴于自己的安装目录，需要设置的环境变量如下图所示：

下载SDK

git clone https://github.com/XradioTech/xradio-skylark-sdk.git

我存放的地址是

C:\cygwin64\home\xradiotech\xradio-skylark-sdk

打开Cygwin64 Terminal

进入~/xradiotech/xradio-skylark-sdk/project/foo/gcc

输入 make config

进行芯片选择和晶振配置

make config

1) 执行 SDK 基础配置（根据提示，进行芯片型号、高频晶振等配置选择），该
配置对所有工程生效。如果需要更改 SDK 基础配置，可再次执行此命令。
2) 正确执行该命令后，将在 SDK 根目录下生成“.config” 文件。
3) 必须执行该命令后才可以执行其他编译命令。

编译和镜像创建的命令是：

make build

编译出错如下：

c:/cygwin64/home/tools/gcc-arm-none-eabi-4_9-2015q2/bin/../lib/gcc/arm-none-eabi/4.9.3/../../../../arm-none-eabi/lib/armv7e-m/softfp\libc_nano.a(lib_a-abort.o): In function `abort':

signalr.c:(.text._getpid_r+0x0): undefined reference to `_getpid'
collect2.exe: error: ld returned 1 exit status
make: *** [../../../project/project.mk:293：foo.axf] 错误 1

没有找到相关的函数，自己写一个头文件syscalls.h放到工程目录下(和main.c在同一个路径下)

#ifndef SYSCALLS_H
#define SYSCALLS_H

History:
28.03.2009 mifi First Version, based on the original syscall.c from
newlib version 1.17.0
03.06.2012 mifi Changed _write_r and _sbrk_r. Added __putchar and use
__HeapLimit to check end of heap.
02.02.2013 nifi Added _exit, _kill and _getpid.

需要在main.c里调用此头文件，最后编译通过！如下所示：
