检查一下是不是用错了COM口？

不知问题解决了没有？
我遇到了类似的问题：
我用的是ESP-WROVER-KIT V4.1板， ESP-IDF v4.2里的examples\get-started\blink.
在Device managermanager里显示COM3和COM4， 用idf.py -p COM3 -b 115200 flash 和idf.py -p COM4 -b 115200 flash命令烧录都失败。

log 看上去是串口没通。

1、你先用串口调试助手之类的打开 COM3 或 COM4，波特率 115200，reset 开发板，看是否有正常 log 输出；
2、你看下你的 ESP-WROVER-KIT，JP2 上 RXD/TXD 有没有跳上？https://docs.espressif.com/projects/esp ... up-options
