Recently I purchased a arduino uno and whenever I try to upload code to it it shows me this :

avrdude done.  Thank you.

Failed uploading: uploading error: exit status 1

I am using Arduino IDE 2.3.2

Hi @apassie. You described the Arduino board you are uploading to as "Uno". Something that can be confusing is there are multiple boards with "UNO" in their name. We need to be certain of exactly which one you have. The reason is that the problem might be caused by the IDE not being correctly configured for your specific board.

Please tell us which of the following boards you are attempting to upload to:

If you aren't sure which one you have, you can provide a picture of the board or a link to the place you bought it from and we'll see if we can identify it.

It's Arduino Uno R3
I purchased it from here : https://www.flyrobo.in/arduino-uno-r3-compatible-board-plus-cable-for-arduino-uno-1?search=arduino&description=true

OK, thanks for the clarification. Please try this experiment and then report back with the results:

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

  1. Connect the Arduino board to your computer with a USB cable.
  2. Press and release the button on the Arduino board that is marked "RESET".

Now please reply here on the forum thread with the answer to the following question:

  • Did you see the "L" LED blink multiple times quickly immediately after you released the "RESET" button?
5

Yes the "L" led blinks 2-3 times quickly then turns off for few seconds then again turns ON

6

OK, that is good. The blink after reset eliminates some possible causes of the upload error. We now know two things:

  • The primary microcontroller on the board is running
  • The bootloader program that handles sketch uploads is present on the microcontroller.

Now we move on to investigating other possible causes of the error.

This error might be caused by having the wrong port selected from the Tools > Port menu in Arduino IDE.

Please perform this experiment to verify that the port you have selected is your Arduino board:

  1. Connect the Arduino board to your computer with a USB cable (if it is not already).
  2. Select Tools > Port from the Arduino IDE menus.

If one of the ports in the menu is labeled with the board name (e.g., "COM42 (Arduino Uno)"), that is the port of your Arduino board.

Select that port from the menu and try uploading again.

If the upload still fails, or if none of the ports in the menu are labeled with the name of your board, add a reply here to let us know and we'll investigate the problem further.

It failed again
didn't work
same error

It is possible for a short or external circuitry connected to the Arduino board to interfere with the upload process, causing this type of upload error.

Make sure the board is not sitting on anything conductive that could short the contacts on the bottom of the board. Make sure there isn't any conductive debris (e.g., strands of wire or component leads) on the board or on the surface the board is sitting on.

If you have a shield or any external circuitry or components connected to your Arduino board, try this experiment:

  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.

didn't work
same error

Given the information gathered so far, I am left with only two possible causes for the upload failure:

  • The bootloader was somehow corrupted.
  • There is physical damage to the microcontroller or its support circuitry.

Even though the blinking LED after you press the reset button does indicate the bootloader is at least somewhat functional, there is still a possibility that it was corrupted in a way that leaves it able to blink the LED, but not to perform an upload. If so, the board might be recoverable by performing a "Burn Bootloader" operation.

I have to warn you there is no guarantee that this somewhat complex procedure which requires additional hardware will recover your board. But if you have the necessary hardware and are up for a challenge and an interesting project then I think it is worth a try.

Prepare ISP programmer

You will need an ISP programmer. If you don't have a programmer, you can use a spare Arduino board as an "Arduino as ISP" programmer.

Arduino as ISP

The following instructions are for using an Arduino board as an "Arduino as ISP" programmer. If you have a dedicated programmer, you can skip to the next set of instructions.

Although the "Arduino as ISP" only works for programming targets of the AVR architecture, you can also use boards of a variety of architectures (e.g., "AVR", "SAMD", "megaAVR") as an "Arduino as ISP" programmer.

ⓘ In the instructions below, the board used as an "Arduino as ISP" is referred to as the "programmer board". The board the bootloader is being burned on is referred to as the "target board".

  1. Disconnect the USB cable of the Arduino boards from your computer.

  2. Make the following connections between the "programmer board" and the "target board".
    ⓘ Refer to the "Connections" table on the SPI library reference page to determine the pin numbers.

    Programmer Target
    CIPO (AKA "MISO") CIPO
    VCC 5V (VCC on 3.3 V boards)
    SCK SCK
    COPI (AKA "MOSI") COPI
    10 RESET
    GND GND

  3. Connect the "programmer board" to your computer with a USB cable.

  4. Select File > Examples > 11.ArduinoISP > ArduinoISP from the Arduino IDE menus.
    The "ArduinoISP" sketch will open in Arduino IDE.

  5. Select your "programmer board" from Arduino IDE's Tools > Board menu.

  6. Select the port of your "programmer board" from Arduino IDE's Tools > Port menu.

  7. Select Sketch > Upload from the Arduino IDE menus.

  8. Wait for the upload to finish.

You are now ready to burn the bootloader using your "Arduino as ISP" programmer.

Burn Bootloader

Instructions for burning the bootloader:

ⓘ It is not possible to do this via Arduino Cloud Editor. You will need to use Arduino IDE or Arduino CLI.

  1. Connect an ISP programmer to your Arduino board.
    If you are using an "Arduino as ISP", then you have already connected it according to the previous instructions.
  2. Select the target board from the Tools > Board menu and any other custom Tools menus (e.g., Tools > Processor).
  3. Select the appropriate programmer from the Tools > Programmer menu.
  4. Tools > Burn Bootloader
  5. Wait for the process to finish successfully.
  6. Disconnect the USB cable of the programmer from your computer.
  7. Disconnect the programmer from the "target board".

Now connect the "target board" to your computer with a USB cable, select its port from the Tools > Port menu, and try uploading a sketch as usual.

Conclusion

Now connect the "target board" to your computer with a USB cable and try uploading again. Does the upload succeed now?

I don't have another arduino
any other fix ?
I tried getting it into DFU mode but when I short reset and GND pin, the RX led lights up and stays on and when I remove the short, RX led turns off but in Device manager it is shown as normal arduino

The problem is probably caused by the Arduino board having suffered permanent physical damage. I recommend you carefully review what you were doing with the board the last time it was in a working state. You may be able to identify the cause of the damage and in this way profit from the mishap by gaining knowledge that will allow you to avoid subjecting boards to the same conditions in the future.

Unless you have the right tools on hand and the skills to use those tools, repair of the board will not be feasible. I suggest you attach a note to the damaged board describing what is wrong with it and put it in your electronics salvage bin. Then purchase a replacement board.

You can support the work Arduino does to provide free open source software, documentation, and hardware designs to the community by purchasing official hardware. It is available from these sources:
