Having board esp32 devkit v1, to get started with arduino ide (installed recommended boards for esp32) I marked board as
DOIT ESP32 DEVKIT V1 (as no other options as like
ESP32 DEVKIT V1 ) so upload gets this error
esptool.py v2.6 Serial port COM3 Traceback (most recent call last): File "esptool.py", line 2959, in <module> File "esptool.py", line 2952, in _main File "esptool.py", line 2652, in main File "esptool.py", line 222, in __init__ File "site-packages\serial\__init__.py", line 88, in serial_for_url File "site-packages\serial\serialwin32.py", line 62, in open serial.serialutil.SerialException: could not open port 'COM3': WindowsError(31, 'A device attached to the system is not functioning.') Failed to execute script esptool the selected serial port Failed to execute script esptool does not exist or your board is not connected
so how do I upload my programs? I would be highly obliged if you could please help me solve this problem. Thank you.
