How did you get past the Invalid DFU Suffix Signature?

Hi @mcriasia. Are you referring to this warning that is show in the upload output?:

Warning: Invalid DFU suffix signature
A valid DFU suffix will be required in a future dfu-util release

If so, you "get past" it by simply ignoring it. It is only a warning. It is not anything you need to worry about.

A tool named dfu-util is used to upload sketched to the GIGA R1 WiFi board. The current version of the tool has an optional feature by which you can specify a "DFU suffix signature" in the dfu-util command. The developers of dfu-util plan to make that mandatory in a future version of dfu-util. So they added this warning to let the users of their tool know that the completely valid command they are using now will become invalid at some hypothetical point in the future after they update to a new version of dfu-util.

This isn't a concern for Arduino users because the exact version of dfu-util in use is completely controlled by Arduino IDE. Likewise, the dfu-util command used to upload is completely controlled by Arduino IDE. At the time when the Arduino developers decide to update to the hypothetical new incompatible version of dfu-util, they will simply update the code that defines the upload command at the same time.

Thank you. That info was very helpful. The odd thing is that with the warning it also says No DFU usb sevuxe available. There are 2 usb ports on the laptop. They are identifies as com 9 and com 12. I swlext the xorrect port through the Tools tab on IDE but when I run the sketch it fails. I go baxk into the tools tab ans it sqitxhes the port. Run the sketch with rhe new port and it still fails and switches the port.

Please take a little time to proof-read your posts before publishing them. An occasional minor typo is fine (I certainly make them myself), but there are so many in your post that it makes it very difficult to understand.

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.

  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.
