I recently bought a genuine Arduino Uno r3 .
As soon as I plugged it in it showed me the device name as 'ATmega16u2 DFU'.. but after a lot of google searches, I burned some hex files onto it and now the device is read in the COM ports in the computer as Communication Port 3, if I install specific drivers for it (.inf files) under the device manager it comes Arduino Uno r3..
The problem is when I try to uploadthe code it says (The RX Led flashes 3 times but then nothing happens..)
Binary sketch size: 444 bytes (of a 32,256 byte maximum)
Estimated used SRAM memory: 9 bytes (of a 2048 byte maximum)
avrdude.exe: stk500_getsync(): not in sync: resp=0x00
I already checked that I am selecting the correct COM and BOARD from the IDE. Installed the board with tons of diferent drivers... ( I have win7 x32).
Do you think this is some driver related issue, defective board or something else ?
The first step is to go into the Arduino IDE preferences and switch on "show verbose output during upload". This in turn allows for much more precise error analysis.

I cannot seem to upload the simple blink program to my Arduino Nano. I keep getting the message:
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x03
What I have tried already with a lot of suggestions on Google. I have tried it on both a Windows 7 & 8 machine and with 2 different Nano's:
Set my Board to Arduino Nano
Set my Processor to ATmega168
Set my port to COM1
On windows 8 turned off driver signature
Installed the FTDI Driver
Checked my drivers in control panel
USB controllers says USB Serial Converter
USB Serial port says USB Serial Port (COM1)
Rebooted a Lot!
When I plugin the nano to the USB it starts blinking the L led 180 times a minute. When I start uploading, L blinks at about 80-100 times a minute, blinks the rx and then start blinking the L led fast again.
As of 2018, if you have a genuine Nano (from Arduino), you could be getting this error because of an update to the bootloader on all Nanos shipped by Arduino after January 2018 (Read the note (highlighted in bold) here: https://www.arduino.cc/en/Guide/ArduinoNano#toc4). You will have to update your Arduino AVR Core to 1.6.21 in Boards Manager Under Tools -> Board in the ArduinoIDE to use your shiny new Nano.
Conversely, if you have an older Nano (older than Jan 2018), but recently updated your ArduinoIDE, you should make sure the Processor you selected is ATmega328P (Old Bootloader) under Tools -> Processor.
If your Nano is not genuine (i.e. a 3rd Party Nano), then you may have to manually install the bootloader required to work with it. (The 3rd party should have documentation about this)
I have a Boarduino Duemilanove w/Atmega 328. I want to upload my program to it. I have W8.1 on my laptop.
The power green led is running and the red led is blinking. When I put the serial cable, but before I upload my program, the arduino.exe gives me the message:
"Arduino: 1.6.5 (Windows 8.1), Board: "Arduino Duemilanove or
Diecimila, ATmega328"
and
Sketch uses 1,030 bytes (3%) of program storage space. Maximum is
30,720 bytes. Global variables use 9 bytes (0%) of dynamic memory,
leaving 2,039 bytes for local variables. Maximum is 2,048 bytes.
and then
avrdude: ser_open(): can't open device "\.\COM2": Access is denied.
Problem uploading to board. See
http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.
This report would have more information with "Show verbose output
during compilation" enabled in File > Preferences."
anyone can help me please?.
I know this one is old but i had the same problem and for me it ended up being the cable. I found a smaller one to do the upload and it worked.
In the IDE, go to tools > board, then select your board. After that, you go to tools > port, and select the serial port or USB port the Arduino is hooked up to. If you are using a mac, the port name should be long, so look for USB in the name. On windows, it should say either COM5// or COM6// or something similar. If not, just play around with different ports and boards (in the ide selection) and see if one of the combinations works. You shouldn't need to play around with the board selection too much, but try different ports. One is bound to work.
i am using arduino isp to program a ATtiny2313 avr microcontroller.
Here is the probelm,
when i was programming the avr chip using the default fuse values, everything worked just fine.
But then, i changed the fuse bytes as i wanted to use an external 16 MHz crystal.
When i changed the lfuse value from 0x64 to 0xff (as per the calculation of the fuse bits), the microcontroller stopped responding.
Now everytime i try to program the microcontroller using arduino uno isp, i get an error message :
avrdude: Yikes! Invalid device signature.
avrdude: Expected signature for ATtiny2313 is 1E 91 0A
and then the fuse bytes shown after verification, very strangely are all set to 0x00 :
avrdude: safemode: Fuses OK (H:00, E:00, L:00)
i dont understand what the hell is happening and i have spent hours trying to figure out the probelm.
should the 16Mhz crystal be connected to the microcontroller while programming ?
PLEASE HELP !
Yes. When you change the configuration bits to use the external oscillator, the internal oscillator is no longer utilised - including during programming. The chip is just stuck in reset until it is provided with an external clock signal. When the ISP attempts to read out a value it is just seeing the data line stuck in the reset state - which is where all the 0x00 values are coming from.
Hook up the crystal or a signal generator to the CLOCKIN pin and you should be able to talk to the chip again.
Had the same issue. If you do not have an external oscillator, you can use
Arduino ISP
On PIN9 you get an osciallator signal you can put on the target on PIN XTAL1.
Saved me two 328p.
My Arduino Uno was all set up and was working fine.
Project: Arduino controls a 9v motor depending on the command given. As the Arduino only provides 5v, I added a 9v battery to it through a transistor
I decided to add new code into the Arduino but when I tried it failed. I have uploaded code thousands of times before (successfully) all of a sudden the IDE keeps giving the following message
avrdude: ser_open(): can't open device ".\COM3": Access is denied.
I have looked up for a lot of solutions on this forum and elsewhere. Here are the things I have tried so far:
Changing the COM port
Disabling all the other devices CONNECTED to COM
Tightening the CONNECTIONS
Re installing all the drivers and the IDE
Rebooting the system
Using another laptop to upload code
All the above have given me the same output for some reason. The built in LED light and the power LED switch on when the board is connected to a power source (my laptop). Could the board have been damaged by any chance? How can I check if the board is spoilt? Should I buy a new board?
this may help;
remove the mcu from the board and connect the board to your PC.
try to open the com port.
if it opens, short TX pin to RX pin.
send some data and check if you are getting the data back. this way you can make sure your usb-ttl is not damaged.
With my verry limited experience with Arduino I've seen that the IDE sometimes resets the saved arduino on startup. Press extra -> Board -> yourboard and try again.
make sure you have the right ports COM1 and COM1
activate it too in arduino
Once it happened to me that a defective USB cable was the culprit. For one board it gave messages like
avrdude: stk500v2_ReceiveMessage(): timeout
But for another board I also got these messages "can't open device - access denied". It's always worth to try another cable.
I am trying to upload this firmware sck_beta_v0_8_6 via Arduino 1.0.5-r2.
I have chosen LilyPad Arduino USB as the board. The device is a Smart Citizen Kit Urban Shield v.1.1.
The upload fails with the following error message:
Found programmer: Id = "BÛR"; type =
Software Version = . ; Hardware Version = .
avrdude: error: buffered memory access not supported. Maybe it isn't
a butterfly/AVR109 but a AVR910 device?
What am I doing wrong?
Sometimes, a different USB cable will make all the difference. There is a wide range in the quality of cables on the market, and sometimes, you get one on the ragged edge of acceptable.
The Arduino lilypad seems to be particularly susceptible to this. Glad this helped.
Press the Reset Button before upload the code, until you hear the "unplug" sound (in windows). Open the IDE and try it again
I had the same error message trying to upload a sketch to an Arduino Leonardo board from a Levovo laptop using Arduino ver 1.0.6. Both Device Manager and Arduino showed the board connected on COM3. Arduino also gave an error message that COM3 was being used by another App. I tried changing USB cables but got the same message. What worked was changing the USB outlet from the top right rear on the Lenovo to the bottom right rear outlet. It connected on COM8 and I was able to upload the sketch. Understand there are speed differences between the two outlets. Now all I need to do is figure out why I cannot upload sketches to the same Leonardo board on my HP laptop with Windows 10 and the most recent Arduino version. Connects on COM6 but hangs up when uploading. (Note: Also had to edit some Arduino library files that worked on ver 1.0.6 but showed compile errors in the latest version.)
I had the same error, but I later found that I had the wrong Arduino type selected, instead of Nano I had Yun.
I had the same issue when trying to upload code into Arduino Micro ( Chinese clone ). Spending hours on Google, flashing new bootloader - still nothing. Physical reset and opening COM port with boundrate 1200 doesn't work. Why?
I HAVE ATMEGA168 INSTEAD OF ATMEGA32u4!
Google is telling, that Arduino Micro got Atmega32u4, but my clone got Atmega168! First of all, check what atmega type do you have by lookup on black soldered chip on Arduino.
So instead of choose "Arduino Micro" on "Board" menu, i choose Arduino Nano and everything works!
I get this same error, avrdude: error: buffered memory access not supported also with garbage-looking output with programmer id # with versions ., when I point avrdude at the serial port of the stock main firmware of my Leonardo-compatible breakout board instead of the serial port offered during the bootloader; it seems that the latter is what avrdude can program?
The normal initial output when actually connecting to the bootloader would be something like:
Connecting to programmer: .
Found programmer: Id = "CATERIN"; type = S
Software Version = 1.0; No Hardware Version given.
To get to the bootloader you can either
press the reset button (if you don't have a reset button, connecting reset to ground), or
briefly connect to the main firmware's serial port at 1200 bps and disconnect
The bootloader will present a different serial USB device than the main firmware's serial USB device, so it may get assigned a different serial port number in your OS, usually the next available one. For instance in Windows my Leonardo-compatible main firmware was assigned COM3 and the bootloader was assigned COM4.
A python script, courtesy of https://nicholaskell.wordpress.com/tag/leonardo/, for doing this serial 'knock':
reset.py:
#!/usr/bin/env python
import serial, sys
serialPort = sys.argv[1]
ser = serial.Serial(
port=serialPort,
baudrate=1200,
parity=serial.PARITY_NONE,
stopbits=serial.STOPBITS_ONE,
bytesize=serial.EIGHTBITS
)
ser.isOpen()
ser.close() # always close port
In Windows land, I have a cmd script for using this in a virtualenv
reset.cmd:
"C:\Program Files (x86)\Python37-32\Scripts\virtualenv.exe" pyreset_virtualenv
pyreset_virtualenv\Scripts\pip.exe install pyserial
pyreset_virtualenv\Scripts\python reset.py COM3
pause
adjust to suit your serial port and python path.
Either way, after getting the bootloader connected, you have a brief window of a couple of seconds where avrdude can connect to the new serial port to start programming before the bootloader will go into the main firmware again, at which point you'll have to do the reset again. So, once you figure out the bootloader serial port, you'll want to prepare the avrdude command line to run in advance, so you can launch it without delay after the reset.
While this answer isn't specific to the lilypad, you need to reset the board to write or read from/to the memory. However, If you are using avrdude in the terminal you must send a specific baudrate(1200 for the Leonardo) then close, wait 2 seconds, and open the port. At that point you can read and write to and from your Arduino. I achieved this using python.
Along the lines of:
Import serial
Import time
Import os
Seri=serial.Serial(yourConnectedPort, specificBaudRate)
Seria.close()
time.sleep(2)
Seri.open()
os.system(your avrdude command)
