New Uno board powers up but will not take any programing

Development Tools IDE 1.x
1

I was attempting to troubleshoot board #1 (first Arduino Uno R3) by opening a new package containing another Arduino Uno R3 board (Board #2). Board #1 will accept programming, but board #2 will not accept programing, even the same program Board #1 accepted ("problem uploading board, see Arduino.cc....troubleshooting").

I have reviewed the trouble shooting guide, but did not find anything applicable. Again, when I plug in (usb) to board #1 everything works fine (for the most part). Not on board #2. Will not accept programming (simple programing) and gives an orange error message. Board #2 was in a sealed ESD package.

Any ideas?

OS Win 10
Arduino 1.8.10

Are both boards IDENTICAL in every way ?

Maybe take a few minutes to READ THIS and add any additional information you can.

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.

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.

Neither option "upload" or " compilation" was checked when I first opened it. I checked "upload". Both boards appear to be identicial. Both were ordered from the same seller at the same time. Also, Port shows 'Com 3' while connected to Board #2, and 'Com 4' while connected to board #1, on the IDE drop down menu

Maybe I should use separate USB ports for each Arduino?

There's your problem. You need to select the correct port from your board from the Arduino IDE's Tools > Port menu before uploading.

Thank you!!!

You're welcome. I'm glad if I was able to be of assistance. Enjoy!
