尝试重新设置ESP32-C3为正确的启动模式: 如果ESP32-C3开发板上有BOOT和EN按钮,可以尝试按住BOOT按钮(或连接BOOT引脚到地),然后按下RST按钮(或连接RST引脚到地)来重置设备,并强制其进入下载模式。 释放按钮后,设备应该能够进入下载模式,并允许你通过串口连接和下载程序。 尝试重新连接ESP32-C3设备:
按照UP主文中所说的话:ESP32自动下载电路时序有微小的不同步,导致复位后BOOT没有拉低。解决办法是先拉低IO0(按下开发板的BOOT键),然后再拉低ESP32上电使能EN脚(按下开发板的EN键),上电时先给EN脚高电平,再给IO0高电平,也就是让设备上电时准确进入BOOT状态。 于是我就按照UP主所教的方法去试了,但是结果...
