Arduino uno upload forever and forever

Using Arduino Avrdude, stk500, Bootloader issues
1

hey guys, I'm with a issue to upload my Arduino code to my Arduino UNO...

I've already showed verbose output during the upload process, but I still with one problem that idk how to resolve.

when I try to upload the code, appears this following message:

     Using Port                    : COM3
     Using Programmer              : arduino
     Overriding Baud Rate          : 115200

avrdude done. Thank you.

Failed uploading: uploading error: exit status 1

I think is a programmer problem, but idk how to fix it. can someone help me please?

Something connected to pins 0,1?
Did it work previously?

yes, I've an 4-channel relay with esp8266 plugged in 0 and 1 pins, and yesterday was working normally

Hi @rbarbaroto. Please try this:

  1. Disconnect the USB cable of the Arduino board from your computer.
  2. Disconnect any shields, modules, external circuitry, etc. from your board.
  3. Connect the Arduino board to your computer with a USB cable.

Now try uploading a sketch to the board again. Does the upload succeed?

This experiment will determine whether the upload error was caused by interference from your external circuitry. If so, you can then focus your attention on identifying the specific problem with the circuit and resolving it.

hey @ptillisch, thank u so much! idk what was wrong but when I separated all the external circuitry from my board I became able to upload my code! thanks!!

Arduino is using pins 0,1 for uploading so they have to be unused while the uploading process is in progress.
You have to disconnect other device every time you want to upload the sketch.
