前言:
下述均为USB TYPEC 数据线正常的情况下的报错,如果数据线或串口有问题
原因1:无法连接到ESP32:串行数据流停止:可能存在串行噪音或损坏
解决方法:ESP32电路板是否供电?电压是否正常?给电路板重新上电。

上传失败:上传错误:退出状态 2
原因2:无法打开 COM9,端口不存在
COM9为任意端口
解决方法:ARDUINO IDE是否打开了多个窗口,并在其它窗口或其它软件打开了串口导致串口被占用?检查其它窗口,关闭该窗口的串口监视功能。

原因3:此芯片是 ESP32 而不是 ESP32-S3。错误的 --chip 参数
ARDUINO IDE 开发板选择错误
解决方法:重新选择正确的开发板,如将开发板更换为ESP32 Dev Module及正确的串口号。
