esp8266 window7开发环境搭建

安装toolchain

下载msys32

在windows环境下我们需要msys32，在linux不需要

https://dl.espressif.com/dl/esp32_win32_msys2_environment_and_toolchain-20181001.zip

下载8266对应的toolchain

在默认的msys下是没有8266的toolchain的，我们需要下载：

https://dl.espressif.com/dl/xtensa-lx106-elf-gcc8_4_0-esp-2020r3-win32.zip

将解压后的xtensa-lx106-elf放到/msys32/opt/下

安装python环境

编译工程

设置环境变量

因为我们使用的是msys32的虚拟环境，所以我们只要设置msys32的虚拟环境变量即可，不需要设置windows的环境变量。这样正好可以让我们在window系统下同时兼容esp32和esp8266的开发环境。
修改/home/xxx[用户]/.bashrc

新增：

export IDF_PATH=~/esp/ESP8266_RTOS_SDK
export PATH=/opt/xtensa-lx106-elf/bin:$PATH

检验环境变量：
重新打开mingw32.exe，执行

xtensa-lx106-elf-gcc -v

# xtensa-lx106-elf-gcc -v
Using built-in specs.
COLLECT_GCC=G:\msys32\opt\xtensa-lx106-elf\bin\xtensa-lx106-elf-gcc.exe

下载最新代码

务必git pull，不要zip解压，windows下很多隐藏文件容易出问题

git pull https://github.com/espressif/ESP8266_RTOS_SDK.git

menuconfig

进入需要编译的工程例子目录

make menuconfig

进行必要的配置。为了接下来的下载，我们需要配置串口：Serial flasher config > Default serial port，根据实际的串口来配置。

On Windows, serial ports have names like COM1. On MacOS, they start with /dev/cu.. On Linux, they start with /dev/tty

编译

make
