i connected the ultrasonic sensor to the 3.3 vcc and ground and the trig and echo pins to GPIO22,1 when i connect the sensor i get MD5 error:"A fatal error occurred: MD5 of file does not match data in flash!" any help will be greatly appriciated...
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...
4. **检查串口设置**：在烧录软件中，确保你选择了正确的串口和波特率。ESP32-C3通常使用115200波特率...

看了一下显示的log信息，貌似题主已经上传成功了，通常来说烧录之前要先保证你的硬件下载电路以及驱动没有问题，把你的板子连接到电脑上面然后打开设备管理器查看串行设备有没有具体设备型号显示，确保这一步没问题之后，检查自动下载电路是否有问题，esp32烧录时需要对IO0进行上下拉操作，做好这些一般来说就都没问题...
针对您遇到的“a fatal error occurred: failed to connect to esp32-s3: no serial data received”问题,以下是一些可能的解决步骤,您可以按照这些步骤逐一排查: 1. 检查ESP32-S3与电脑的连接 确保物理连接稳定:检查USB线是否牢固连接在ESP32-S3开发板和电脑的USB端口上。 更换USB线:有时USB线本身可能存在问题...
