Hello,
I am having an issue with uploading a project to my Arduino. I have tried my Nana, Pro Mini and Micro they all have the same issue. I have made sure that I am using the proper COM port and that the correct board is selected. I have tried changing USB cables and it is the same issue. It compiles the sketch then just hangs for a while at uploading then I get this error:
Arduino: 1.8.10 (Windows 10), Board: "Arduino Pro or Pro Mini, ATmega328P (5V, 16 MHz)"
Sketch uses 924 bytes (3%) of program storage space. Maximum is 30720 bytes.
Global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes for local variables. Maximum is 2048 bytes.

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.
How can I fix this issue?
Thanks!
