如果ESP32是通过编程运行的,检查编写的代码是否有语法错误、逻辑错误或其他问题。 尝试简化代码并逐个功能进行测试,以确定问题所在。 ESP32进入下载模式: 对于某些ESP32开发板,需要将其置于下载模式才能连接。通常,这需要将GPIO0引脚接地(GND),并在上电时保持该状态。 确保在连接和上传代码时,GPIO0引脚已正确接地。
ESP32 无法烧录程序,报错:Failed to connect to ESP32: No serial data received.且开发板上电EN脚不是高电平的解决方法。 参考:【ESP32烧录异常解决办法-哔哩哔哩】 https://b23.tv/wH0FULt 结论:拉高EN脚电平,上电,拉低BOOT脚电平,开始烧录,拉低EN脚电平,烧录结束 原因分析:由于近期看到了很多使用ESP32...
