avrdude stk500v2 ReceiveMessage timeout

Question

This is the main error that I get when I try to run my ARDUINO program  The full list of errors is as follows   avrdude  stk500v2 ReceiveMessage    timeout avrdude  stk500v2 ReceiveMessage    timeout avrdude  stk500v2 ReceiveMessage    timeout avrdude  stk500v2 ReceiveMessage    timeout avrdude  stk500v2 ReceiveMessage    timeout avrdude  stk500v2 ReceiveMessage    timeout avrdude  stk500v2 getsync    timeout communicating with programmer   My code is as follows   int led 13  void setup         pinMode 13 OUTPUT      void loop         digitalWrite 13 HIGH       delay 1000       digitalWrite 13 LOW       delay 1000       I have tried updating the drivers  they are fully updated  and downloading some programs  I have Windows 7 and my arduino is a MEGA 2560  It shows up in the Device Manager and all of my connections are correct  The green PWR light is on and so is the flashing L light  The RX and TX lights flash when I update  I have tried almost everything on the web  What is the problem

The error message basically means that the programmer is unable to contact the bootloader on the device; the code you're trying to upload has no bearing on the problem.

What causes this can be numerous and varied, some possible issues:

UART communications
- Blinking is happening, so hopefully you aren't using the wrong port. It might be worth checking again though, sometimes USB COM devices install on strange port numbers.
- Connect TX to RX (and disconnect them from the AVR if possible) then open a terminal on the COM port, you should see characters echoed if you type them. If you don't, something is wrong up-stream of the chip, it could be the communications chip (I think the Arduino 2560 uses a secondary AVR instead of an FTDI for some reason, so that could be broken, either its software or hardware)
ATmega* bootloader
- The AVR is not executing the bootloader for some reason. If the programmer is not resetting the micro before attempting to connect, this might be the reason. Try to reset the AVR (press and release the button) while the programmer is attempting to connect. Sometimes software that runs in a tight loop will prevent the bootloader from connecting.
- Barring that, the fuses might have gotten messed up or the code erased. You would need to reflash the bootloader and proper fuses, again, see the appropriate info page for your device.
Arduino Mega 2560 only: ATmega8U/16U software
- Might not be working and would need reprogramming. See the Programming section on the info page, you will need the firmware and Atmel-compatible DFU (device firmware update) software on your computer to reflash the target.
Hardware damage to the board, AVR(s), or FTDI chip
- You're hosed; need a new chip.

To my humble understanding this error arises with different scenarios   you have selected the wrong port or you haven t at all  go to tools ports ans select the com port with your Arduino connected to you have selected the wrong board  go to tools board and look for the right board you have one of these arduino s replicas or you don t have the boot-loader installed on the micro-controller  I don t know the solution to this  if you know please edit my post and add the instructions   windows only  you don t have the right drivers installed  you need to update them manually  sometimes when you have wires connected to the board this happens  you need to separate the board from any breadboard or wires you have installed and try uploading again  It seems pins 0  RX  and 1  TX   which can be used for serial communication  are problematic and better to be free while uploading the code  Sometimes it happens randomly for no specific reasons    There are all kind of solutions all over the internet  sometimes hard to tell the difference with magic  Maybe Arduino team should think of better compiler errors helping users differentiate between these different causes   The same problem happened to me and none of the solutions above worked  What happened was that I was using an Arduino uno and everything was fine  but when I bough an Arduino Mega 2560  no matter what sketch I tried to upload I got the error   avrdude  stk500v2 ReceiveMessage    timeout   And it was just on one of my windows computers and the other one was just ok out of the box    Solution    What solved my problem was to go to tools boards Boards Manager    and then on top left of the opened windows select  updatable  in  Type  section  Then select the items in the list and press update on right    I m not sure if this will solve everyone problem  but it at least solved mine

I got this error because I didn t specify the correct programmer in the avrdude command line  You have to specify  -c arduino  if you are using an Arduino board   This example command reads the status of the hfuse   avrdude -c arduino -P  dev ttyACM0 -p atmega328p -U hfuse r - h

I ve connected to USB port directly in my laptop and timeout issue has been resolved   Previously tried by port replicator  but it did not even recognized arduino  thus I chosen wrong port - resulting in timeout message   So make sure that it is visible by your OS

I had the same problem  and in my case  the solution was updating the usb-serial driver using windows update on windows 10 device s manager  There was no need to download a especific driver  I just let windows update find a suitable driver

This isn t really a fixing solution but it may help others  Unlike Nick had said for me it was due to code in my program  I have the mega ADK model  The issue was tied to a switch statement for processing and parsing the returned byte   from the usb connection to the Android  Its very strange because it would compile perfectly every time but would fail as the OP had stated  I commented it out and it worked fine

My aurdino mega 2560 returned same error  It seems the problem exists in unofficial clones  The issue solved by pressing reset button just before uploading starts  as advertised in following video   https   www youtube com watch v tAzjO4v7oF4 amp list LLDn5ewJDzz53IiwWmZTgQnQ amp index 1

Open Terminal and type     sudo usermod -a -G dialout     This command is optional       sudo chmod a rw  dev ttyACM0       This command must succeed

Ensure the serial monitor is not running and nothing is reading writing dev tty S0  or whichever port you re using   which may cause uploading interference

If you use the ino command line   ino upload   it can be because you use the arduino software at the same time  try to kill it

Another possible reason for this error for the Mega 2560 is if your code has three exclamation marks in a row  Perhaps in a recently added string   3 bang marks in a row causes the Mega 2560 bootloader to go into Monitor mode from which it can not finish programming           lt --- breaks Mega 2560 bootloader   To fix  unplug the Arduino USB to reset the COM port and then recompile with only two exclamation points or with spaces between or whatever  Then reconnect the Arduino and program as usual   Yes  this bit me yesterday and today I tracked down the culprit  Here is a link with more information  http   forum arduino cc index php topic 132595 0
