Pololu 3pi downloading programs

My Pololu 3pi will not download any code from USB or programmer, sure there's a simple fix, involving the reset button, but just can't remember it..

Any help would be realy useful.

I moved your topic to an appropriate forum category @cactusme.

In the future, please take some time to pick the forum category that best suits the subject of your topic. There is an "About the _____ category" topic at the top of each category that explains its purpose.

This is an important part of responsible forum usage, as explained in the "How to get the best out of this forum" guide. The guide contains a lot of other useful information. Please read it.

Thanks in advance for your cooperation.

Hi @cactusme. I'm going to ask you to provide the full verbose output from an upload attempt.


:exclamation: This procedure is not intended to solve the problem. The purpose is to gather more information.


Please do this:

  1. Select File > Preferences... (or Arduino IDE > Settings... for macOS users) from the Arduino IDE menus.
    The "Preferences" dialog will open.
  2. Uncheck the box next to Show verbose output during: compile in the "Preferences" dialog.
  3. Check the box next to Show verbose output during: ☐ upload.
  4. Click the "OK" button.
    The "Preferences" dialog will close.
  5. Attempt an upload, as you did before.
  6. Wait for the upload to fail.
  7. You will see an "Upload error: ..." notification at the bottom right corner of the Arduino IDE window. Click the "COPY ERROR MESSAGES" button on that notification.
  8. Open a forum reply here by clicking the "Reply" button.
  9. Click the <CODE/> icon on the post composer toolbar.
    This will add the forum's code block markup (```) to your reply to make sure the error messages are correctly formatted.
    Code block icon on toolbar
  10. Press the Ctrl+V keyboard shortcut (Command+V for macOS users).
    This will paste the error output from the upload into the code block.
  11. Move the cursor outside of the code block markup before you add any additional text to your reply.
  12. Click the "Reply" button to post the output.
