avrdude: stk500v2_ReceiveMessage(): timeout

问题:

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?

回答1:

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:

1. 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)

2. 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.

3. 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.

4. Hardware damage to the board, AVR(s), or FTDI chip

   • You're hosed; need a new chip.

Check this forum post for some more ideas.

回答2:

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.

"!!!" <--- 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

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

To my humble understanding this error arises with different scenarios

1. 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
2. you have selected the wrong board. go to tools>board and look for the right board
3. 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.
4. (windows only) you don't have the right drivers installed. you need to update them manually.

5. 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.

6. 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.

回答5:

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.

回答6:

I was running this code from Arduino setup , got same error resolve after changing
serial port to COM13
GO TO Option
tool>> serial port>> COM132

回答7:

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.

回答8:

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.

回答9:

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.

回答10:

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.
