Unable to upload anything

Development Tools IDE 1.x
1

Hey all,

Not sure whether this specific problem has been encountered before, but my Seeeduino (imitation Arduino) is not accepting uploads.

What is happening is that when I plug the board in, it starts spamming the serial output with seemingly random values, and will not accept serial input from USB. If I press the reset button, it stops uploading with the error that it cannot synchronize, as I'd expect from resetting the serial connection.

Why would it refuse to accept an upload, and insist on spamming the serial port?

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.
