Arduino Nano board uploading problem

Arduino: 1.8.9 (Windows 7), Board: “Arduino Nano, ATmega328P”

Sketch uses 3708 bytes (12%) of program storage space. Maximum is 30720 bytes.
Global variables use 362 bytes (17%) of dynamic memory, leaving 1686 bytes for local variables. Maximum is 2048 bytes.

This report would have more information with
“Show verbose output during compilation”
option enabled in File → Preferences.

Please do this:

  • (In the Arduino IDE) File > Preferences
  • Uncheck the checkbox next to “Show verbose output during: compilation”
  • Check the checkbox next to "Show verbose output during: upload
  • Click “OK”
  • Sketch > Upload
  • After the upload fails, you’ll see a button on the right side of the orange bar “Copy error messages” (or the icon that looks like two pieces of paper at the top right corner of the black console window in the Arduino Web Editor). Click that button.
  • In a forum reply here, click on the reply field.
  • Click the </> button on the forum toolbar. This will add the forum’s code tags markup to your reply.
  • Press “Ctrl + V”. This will paste the upload output between the code tags.
  • Move the cursor outside of the code tags before you add any additional text to your reply.

avrdude done.  Thank you.
