由于IDF使用的是FREERTOS需要修改一些文件，将`0001-add-fixed-of-rtthread.patch` 这个文件拷贝到安装的时候的IDF的代码目录，执行命令 `git apply 0001-add-fixed-of-rtthread.patch` 打上patch

```
cd esp/esp-idf
git checkout v4.4
git am 0001-add-the-config-of-RTTHREAD.patch

如果不想用patch文件，我已经将代码上传到github上面，可以进入[supperthomas/esp-idf](https://github.com/supperthomas/esp-idf) 下载最新的master分支。修改之后的IDF，原来的IDF的example还是正常使用，互不干扰。
