Kindly assist. Im getting this error message when i try to upload to my esp8266 board. I have tried reinstalling arduino ide and libraries. Have also replaced my previous board with a new one.
" fatal esptool.py error occurred: Cannot configure port, something went wrong. Original message: PermissionError(13, 'A device attached to the system is not functioning.', None, 31)esptool.py v3.0
Serial port COM9"

This could occur if your device has bad firmware loaded on it (so its crash looping and not available to be spoken to). Placing in program mode as desribed badly below will help.
It may also mean your device is not connected correctly - you did not say if your board has a builtin programmer or not.
I would double check the connection if there is an external programmer and then make sure you are in program mode (usually its boot and reset buttons, hold one and press the other, the internet will know)
Hope that helps.
Thank you Christopher. Let me try uploading code while holding one button and pressing the other to see what happens
