Re: The serial port is disconnected?
What hardware are you using? What software, what OS, do you use a VM?
Re: The serial port is disconnected?
The hardware is ESP32S3-Eye, no VIRTUAL machine is used, and the operating system is Windows. And I tried again later, there was a permission error, I found online that the serial port was occupied, may I ask how I should solve it?

Re: The serial port is disconnected?
That board uses the internal USB-serial-JTAG converter. You may have firmware loaded in there that is stuck in a bootloop, making it hard to reprogram it. The way around that is to manually put the board into download mode: hold the button labeled 'DOWNLOAD', press and release the button labeled 'RST', release the 'DOWNLOAD button and try uploading the program again.

Thank you very much. It's ready for normal use
