Hi @jinyuanqing Thank you for the error report.
I suspect that COM3 is not the port related to the ESP device. Please open Device Manager and double check whether device is recognized correctly and it's attached to the port.
com3 is Normal and usable."serial.serialutil.SerialException: could not open port 'COM3': PermissionError(13, '拒绝访问。', None, 5)" this is a question.
@jinyuanqing We recommend taking the following steps:
mode
mode
If failure still happens, please open Device Manager and check for any signs of a misconfigured device. If you discover one, remove it from Device Manager, including drivers. Run idf-installer to reinstall drivers https://github.com/espressif/idf-installer#manual-installation-of-drivers. Plug in the device.
If the problem persists, use UsbTool to switch driver.
If the problem persists, use a different USB cable and a different USB port.
If the problem persists, use a different ESP32 board, ideally from a different batch.
If the problem persists, use a different computer.
