I know there were a lot of topic here with this issue, but since this error represents a lot of issues related with the Arduino, I need to create a topic for my own case. So when I try to upload example sketch of blinking built in led (or whatever) I get this: avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00 avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x00 avrdude: stk500_getsync() attempt 3 of 10: not in sync: resp=0x00 avrdude: stk500_getsync() attempt 4 of 10: not in sync: resp=0x00 avrdude: stk500_getsync() attempt 5 of 10: not in sync: resp=0x00 avrdude: stk500_getsync() attempt 6 of 10: not in sync: resp=0x00 avrdude: stk500_getsync() attempt 7 of 10: not in sync: resp=0x00 avrdude: stk500_getsync() attempt 8 of 10: not in sync: resp=0x00 avrdude: stk500_getsync() attempt 9 of 10: not in sync: resp=0x00 avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x00 My Arduino was working some days ago, and it "was broken" about 4-5 days ago. And i spent about a week to find the problem by myself, but false. I tried to burn a new bootloader using these programmers, but got different errors for different programmers (sorry, couldn't take a screenshot when this menu is opened): [image] Important note: I can use my Arduino to upload a sketch to my ESP32 cam and it works as needed when I change the board to ESP32. The L led is blinking as expected. Reset button and reseting via pins are working as expected. So my Arduino IS NOT BURNED. MY ARDUINO STILL OUTPUTS TO SERIAL THE DATA FROM OLD SKETCH! Characteristics: Board: Arduino Uno with ATMEGA328P microcontroller Port: /dev/ttyACM0 (successfully connected) VID: 0x2341 PID: 0x0043 SN: some_long_number_which_I_couldnt_copy Programmer: Not sure, just connected the Arduino to my PC via USB.

Look, if do not pull out the 328P (another option is keep it down by grounding the RESET pin, the best with small resistor ~1k or smaller) you can use it as transceiver for another device only with some lucky circumstances.

Oh, finally I could get some kind of debug thing. Here is the output.

Thank you. Failed uploading: uploading error: exit status 1 Hm, however, looks like there is nothing in this log

[image] alkhachatryan: looks like there is nothing in this log It is true that it doesn't result in any more information about the errors. However, it is useful to verify that the IDE was correctly configured (e.g., correct board selected from the Tools > Board menu, correct port selected from the Tools > Port menu). I see that you do have everything correctly configured so we can eliminate those possible causes of the upload failure. 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. Connect the Arduino board to your computer with a USB cable. 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? I see that you already mentioned the LED: [image] alkhachatryan: The L led is blinking as expected. However, it is not clear whether you are referring to the LED blinking as the result of the sketch that happens to be running on the board, or this short sequence of quick blinks after a reset that is independent from the sketch (it is done by the bootloader program). I am asking whether the latter occurs.

Check the video video_2024-01-16_12-41-24.mp4 Google Drive file.

It looks like the bootloader is still there - fast 3 blinks immediately after reset is entry point to the bootloader.

Thanks. The video makes it clear that the bootloader program is present and at least functional enough to make the blink. Even though this doesn't provide evidence of a problem with the bootloader, I am left with two possible causes of the upload failure: The bootloader program is partly corrupted There is physical damage to the hardware In the case of your specific UNO board, which has the socketed ATmega328P microcontroller chip, it might be possible to recover the board from physical damage by replacing the ATmega328P. However, that requires acquiring a replacement chip (unless you happen to have one on hand) and burning the bootloader to the new chip (unless the seller of the one you acquire installed the bootloader on the chip in advance, which is less common). On the other hand, it might be possible for you to attempt to restore a corrupted bootloader right away by performing a "Burn Bootloader" operation. As I mentioned above, even if that doesn't recover the board, the experience might still be useful to you later if you attempt to replace the ATmega328P. I should warn you though that there is no guarantee that the "Burn Bootloader" operation will restore your board. If you have the necessary hardware on hand and are up for a challenge it is worth a try at least: 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". Disconnect the USB cable of the Arduino boards from your computer. 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 Connect the "programmer board" to your computer with a USB cable. Select File > Examples > 11.ArduinoISP > ArduinoISP from the Arduino IDE menus. The "ArduinoISP" sketch will open in Arduino IDE. Select your "programmer board" from Arduino IDE's Tools > Board menu. Select the port of your "programmer board" from Arduino IDE's Tools > Port menu. Select Sketch > Upload from the Arduino IDE menus. 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: 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. Select the target board from the Tools > Board menu and any other custom Tools menus (e.g., Tools > Processor). Select the appropriate programmer from the Tools > Programmer menu. Tools > Burn Bootloader Wait for the process to finish successfully. Disconnect the USB cable of the programmer from your computer. Disconnect the programmer from the "target board". Conclusion Now connect the "target board" to your computer with a USB cable and try uploading again. Does the upload succeed now?

Is it possible to burn it through esp? I have only 1 uno and 1 esp32 cam

Maybe this help: [image] Programming AVR with an ESP32 with arduino as ISP Avrdude, stk500, Bootloader issues I loaded the arduino as ISP code into an ESP32 to program a atmega328PB over SPI connection.
