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,但是结果是仍然
连接ESP32与SD卡时遇到"SD mount failed"错误可能是因为硬件连接问题、SD卡异常、库配置错误、电源供应不足等原因。解决方法包括检查硬件连接，确认SD卡正常，检查库的支持和配置，确保正确的电源供应，检查SD卡是否被格式化，查看串口输出以获取更多信息。尝试升级或更改SD卡库、检查初始化时序、设置适当的SPI时钟速率...
One of the ways to solve this is holding-down the “BOOT/FLASH” button in your ESP32 board while uploading a new sketch at the same time. But having to worry about this every time you want to upload new code can be tedious, specially when you’re testing and debugging your code....
Connecting...字样时候按住boot按钮即可,等到出现烧录的时候就可以松开了

I've tried to create a small breakout board for the ESP32-WROVER-E with (what I believe) only the most minimalistic logics. Unfortunately however, I do get the following error when trying to program the microcontroller: "A fatal error occurred: Failed to connect to ESP32: Timed out waiti...
