Arduino Nano Upload Fail

skj_2002 · December 28, 2025, 10:59pm

Hi,
I am new to electronics and Arduino. I am currently using Arduino Nano CH340P and keep failing to upload the sketch.

Does anyone have suggestions on what else I could check or try?

Thank you.

Hi @skj_2002. A program called a "bootloader" is stored in a special area of memory in the Nano board's microcontroller. The classic Nano (as well as its 3rd party derivatives) have been manufactured with two different types of bootloader installed.

You must configure the Tools > Processor menu in Arduino IDE according to which bootloader is installed on your Nano. Having the incorrect configuration selected in this menu is one of the potential causes of uploads failing with the "avrdude: stk500_recv(): programmer is not responding" error.

The multiple blinks on reset tell us that your Nano board has the modern bootloader installed.

I can see from the verbose upload output that you have Arduino IDE incorrectly configured for use with the Nano boards with the "old bootloader".

Select Tools > Processor > ATmega328P from the Arduino IDE menus to configure it for use with the modern bootloader and then try uploading again.

Hopefully this time the upload will finish successfully.

skj_2002 · December 28, 2025, 11:37pm

Thank you @ptillisch for the reply.

I see a single blink after reset. After I select Tools > Processor > ATmega328P and got a new error.

It's really weird that both processors are failing to respond.

The global variable uses 9 bytes of dynamic memory (0%), leaving 2039 bytes of local variables. The maximum is 2048 bytes.

It compiles correctly.

Verify IDE >> TOOLS >> PROCESSOR >> ATmega328P (Old bootloader)

Is your USB cable for power-only (a phone charger) , or data?

ptillisch · December 29, 2025, 1:15am

Good point. This does indicate that your board has the "old bootloader" and thus the previous Tools > Processor > ATmega328P (Old bootloader) configuration was the correct one.

skj_2002 · December 29, 2025, 1:19am

Thank you @xfpd.

I am not sure what type of USB cable I have with me. If I see USB-SERIAL CH340 (COM2) in device manager, am i using a USB cable for data?

xfpd · December 29, 2025, 1:55am

That is a good data cable.

robot_tech5443 · December 29, 2025, 1:37pm

this kept happening me as well. Try pressing the white button while removing the cable it resets the arduino or the arduino might be damaged

dilberto · December 29, 2025, 1:50pm

Hi @skj_2002 !

From Google Gemini AI:

AI Overview

The STK500 is an older Atmel AVR programmer, often seen in Arduino contexts as an error source (avrdude: stk500_recv(): programmer is not responding) or a hardware tool for burning bootloaders, requiring specific setup (like programmers.txt edits or using it as an ISP) to work with the Arduino IDE, but typically, modern Arduinos use simpler USB-to-Serial chips, making direct STK500 use for simple sketches less common than fixing general upload errors by checking COM ports, cables, and board selections.

xfpd · December 29, 2025, 2:15pm

Close the Serial Monitor window, verify board, port, and processor... and try to upload again.

skj_2002 · December 29, 2025, 11:23pm

I tried to upload with same board and same cable but with different computer. Then, I could successfully upload.

I'm not sure why Arduino Nano was not happy with my labtop yesterday. My labtop is still failing to upload. Is there any drivers to be updated or downloaded for clone board?

xfpd · December 30, 2025, 12:37am

No other drivers are needed.

You've proven your cable and Arduino work. It's your computer you need to examine.

Is your laptop USB port clean and reliable?

Did you do any projects with motors or solenoids or anything requiring high-current?
