ESP32-S3 USB自动下载问题

Postby Leslie-Yuan » Thu May 30, 2024 8:20 am

使用TypeC直接用USB连接芯片GPIO19、20来自动下载失败,电脑可以识别到芯片,但是自动下载就是烧录不行,
必须要下拉BOOT0才能正常操作,但是在买的开发板是可以自动下载的,原理图也是一样的。有哪些地方要注意?
=================================================================================================
esptool.py v4.5.1
Serial port COM11
Connecting....

A serial exception error occurred: Write timeout
Note: This error originates from pySerial. It is likely not a problem with esptool, but with the hardware connection or drivers.

已解决:是COM口的问题,如有遇到同样情况的,可以试一下打开设备管理器>查看>显示隐藏的设备>端口,把端口里的全部卸载掉然后重新插入ESP32-S3,就可以自动下载了,就是COM驱动的问题。
