esp32 win7开发环境搭建

环境

系统:win7
hw target:esp32c3

注意:很多问题都跟git的网络有关,要仔细看错误提示。很多错误需要尝试多遍,才有可能成功。

安装包

离线包安装 https://dl.espressif.com/dl/esp-idf/?idf=4.4

更新最新代码

将安装的IDF_PATH更新成最新的git版本 https://github.com/espressif/esp-idf

更新submodule

git submodule update --init --recursive

安装python virtual environment

install.bat

设置环境变量

export.bat

编译工程

设置hw 平台类型

idf.py set-target esp32c3

错误1:

Unable to checkout '4f5e89fa84ce1d178a6765b8b46f2b6f91216677' in submodule path 'components/libsodium/libsodium'

解决1:
看日志是git无法成功,我们改为手动git pull,如果提示 openssl 10054错误。则

git config --global http.sslVerify "false"

其后还有很多的失败,基本需要逐个确认,多次执行

git submodule update --init --recursive

配置成功
