本文详细记录了在MSYS2环境下配置ESP-IDF开发环境的过程，包括编译和烧录示例程序的步骤。作者从打开mingw32.exe开始，逐步进入ESP-IDF目录并编译hello_world示例，过程中遇到编译工具链版本不匹配及串口烧录失败的问题，并尝试解决。

首先编译demo

打开C:\msys32目录下的mingw32.exe然后执行下面的操作

出错了。。。。。

看了以下端口号

DZ0012+Administrator@DZ0012 MINGW32 ~
# cd dev
-bash: cd: dev: No such file or directory

DZ0012+Administrator@DZ0012 MINGW32 ~
# cd /dev

DZ0012+Administrator@DZ0012 MINGW32 /dev
# ls
clipboard dsp null random sda3 sda7 stdin urandom
conin fd ptmx sda sda4 sda8 stdout windows
conout full pty0 sda1 sda5 shm tty zero
console mqueue pty1 sda2 sda6 stderr ttyS12

DZ0012+Administrator@DZ0012 MINGW32 /dev
结果是 ttyS12

于是make menuconfig修改串口

选这个进去

然后

选第一个修改

改成自己的

然后再次make

make flash

看起来先装个gcc在windows上
