偶尔遇到，多刷几次就可以了

Note
If you’re just seeing Connecting....____.... on the screen and the flashing fails, that might be a sign that the ESP is defect or cannot be programmed. Please double check the UART wires are connected correctly if flashing using a USB to UART bridge. For some devices you need to keep pressing the BOOT button until flashing has begun (ie. Geekcreit DOIT ESP32 DEVKIT V1).

看上去是数据线的问题，因为前面的都是正常的，开始刷机才出现连接异常

不稳定，多试试就好了

Mac试了好几回，居然成功了，感觉是Mac旧驱动不大稳定的问题。
