我对这类事情很陌生，所以任何帮助都会受到赞赏。我花了2天时间试图纠正我得到的错误，但我仍然没有运气。我在这里按照本教程http://www.themakersworkbench.com/tutorial/how-use-amazon-alexa-control-linknode-r4-esp8266-4-channel-relay-board。我使用他在教程中链接的相同电缆（：//amzn.to/2h7PdEz）（usb到uart电缆）（：//amzn.to/2h7RDDf）（5v 2a电源）。我从提供的链接中收集了代码并使用相关信息更新它以连接到我的wifi，除此之外我没有对代码进行任何更改。 （他们不会让我把链接放入，因为这是我的第一篇文章，只需将http添加到链接的前面）
我遇到的问题是，当我尝试将我的代码上传到主板上时，代码编译得很好，然后遇到下面列出的错误。我确信这很简单，我到处搜索确保正确的设置，但我仍然无法上传代码。我甚至尝试在115200进入“AT”并获得输出`UC的串行监视器。只是为了涵盖一些基础知识，我将tx连接到电路板上的rx，将rx连接到电路板上的tx，并接地。电源打开，我可以看到电源指示灯点亮，直接插入墙壁。我下载了1.8.3 arduino ide并安装了ESP8266板卡管理器，我使用通用版闪存模式QIO，波特率为115200。
感谢您抽出时间来看看这个，我又很新，所以如果这个问题已经得到解答，请指导我正确的方向（我自己搜索了很多）。
