avrdude: stk500_getsync() effort 1 of 10: not in sync: resp=0x00

Is this some kind of joke? Who is AVR Dude, and what does he take confronting me trying to upload a sketch to my Arduino? If you're getting this error when trying to upload code to your Arduino board – information technology can be Actually frustrating!

I wish I could say this happens because of 1 unmarried trouble – but this error pops up for many reasons… In this lesson nosotros are going to go through a "laundry list" of possible solutions. Nosotros'll first at the most mutual and easiest, and motion on to more than detailed troubleshooting tasks if those don't work.

By the stop of this lesson, AVR Dude should be hitting the route, and your code will be loading on your Arduino lath.

Avrdude: stk500_received: programmer is not responding? Is this some kind of joke? Who is avrdude and what does he have against me trying to upload a sketch to my Arduino? If you lot continue getting this error when you're trying to upload code to your Arduino board, it can be really frustrating. I wish I could say that there was one unmarried reason why this happens. Merely this error pops up for many unlike reasons. In this video lesson, we are gonna go through a laundry list of possible solutions to go yous going. We'll showtime at the about common and easiest way to troubleshoot this and and so move up on to more detailed options. By the terminate of this lesson, avrdude should be hitting the road and your lawmaking will be loading onto your Arduino board. Stay tuned. (inspirational music)

Bank check out our membership program to learn the software and hardware skills you'll need to build your own projects. So who is this avrdude anyway? Well, avrdude is a utility that stands for AVR Download Uploader and when you get this mistake, information technology's caused past a generic connection mistake between your estimator and the Arduino and it tin can result from many dissimilar things. When you see this error, it might feel similar yous've got some programming ghost living inside your Arduino IDE. Only really, it'south just basically telling y'all hey, something is not right when I'm trying to upload code to your Arduino board. So permit's jump in to our listing of like shooting fish in a barrel things that might be able to ready this error. All correct, the first one, simply disconnect and reconnect the USB cable that you're using then try uploading again. If that doesn't work, endeavour pressing the reset push on your Arduino board. Then try the upload again. Okay, if this still isn't working, try to restarting your Arduino IDE and then meet if you tin can upload. All right, are you lot still getting the fault? No worries, make sure that you have the right lath selected. So y'all wanna go to Tools, Board and make certain that the board there'due south the actual ane that you're trying to upload your code to. Okay, so you know you take the correct board selected but yous're still getting the fault. Okay, so you lot've checked the USB cable, you tried resetting the board, you've restarted the Arduino IDE, you made certain that you had the right lath selected but you're still getting the avrdude error. Now it's time to make sure that you've got the correct port selected. So to notice the port, you become to Tools, Serial Port and you lot select the port. Now, if you don't know which one is the right port, hither'southward a quick way to figure that out. So look at that port list. And so disconnect the USB cable, go to Tools, Series Port, and so see which ports are listed. It could be com4, com5, something along that line if y'all're on a PC or USB something if you're on a Mac. Then reconnect the USB cable. At present go back to Tools, Series Port and see which port has appeared that wasn't at that place earlier. So that's gonna exist the port that your Arduino's using. Select that port and attempt uploading once more. At present, if you're still getting the avrdude error, here'due south the last easy thing you tin can try. Make sure that digital pins zero and one do not have any parts connected, including any shields. These are the transmit and receive pins on about Arduino boards and if you take something continued in that location, information technology can interfere with uploading lawmaking to your Arduino lath. At present, if you lot have tried all of these steps and avrdude is still giving y'all trouble, information technology's fourth dimension for united states of america to showtime doing some troubleshooting. What we're gonna attempt to do is isolate the issue by replacing things. The trouble could be with the computer you lot're using, the problem could be with the Arduino lath you're using. Or the problem might exist with the USB cable that you're using. Let'due south outset with the USB cable. Simply switch it out with another one. Now, you might be like really? The USB cable? How likely is that? Well, you might be surprised how often these things fail. And by trying a different ane, you know that you'll have ruled that out. And then let's say it'south not the USB cable. Now what you'll wanna exercise is cheque if the issue is with the computer. If you have another Arduino board handy, try uploading a sketch to that other Arduino lath. If you're able to upload a sketch, that tells you that the commencement Arduino board you tried may have the consequence. Or if yous have another computer handy with your Arduino IDE installed on it, effort taking the Arduino board that wouldn't upload the sketch and attempt uploading a sketch using that other computer. If you lot're able to upload a sketch, that might tell you lot the computer'south giving you the trouble. And so if yous determine that the issue is with the calculator, first attempt reinstalling the Arduino IDE. Make certain to run through all those checks that we had at the outset, all those easy steps. If you're still getting the avrdude error, and then effort reinstalling the drivers. Now, if the event was with the specific Arduino board, it gets a little more difficult. If you have an Arduino board where the microcontroller tin come up out of the board, similar an Arduino Uno, for example, make sure that that microcontroller is seated correctly. If that doesn't set up the fault, you may need to burn the bootloader back onto the microcontroller. At present, that's across the telescopic of this lesson simply I'll brand sure to accept a link in the description for you to learn how to practice that. But if those aren't working, information technology could be that your Arduino lath has been bricked. That is it's simply not gonna work anymore, which is unfortunate but I definitely recommend trying all the troubleshooting steps a couple more than times before you give upward. Well, I hope one of these helped solve your problem and avrdude has left you alone. Nosotros'll just run through those like shooting fish in a barrel tips again i more fourth dimension. You wanna try disconnecting and reconnecting your USB cable. You lot can effort pressing the reset push button. You can try restarting the Arduino IDE. Yous wanna double check that you've got the right board selected in the Arduino IDE. Y'all wanna make sure that you have the right port selected. And you lot wanna brand sure digital pins zero or one, the receive and transmit pins, don't have anything connected to them, including any shields. Well, hey, I hope you have a fantastic solar day. Thanks a ton for watching and I wait frontward to seeing yous next time. Bye. (lively music)

So who is this AVR dude and what is avrdude: stk500_recv() error?

AVRDude is a utility used by the Arduino IDE. It stands for AVR Downloader Uploader and it allows yous to load your lawmaking onto your Arduino board. The avrdude: stk500_recv() mistake is caused by a generic connection error between your calculator and the Arduino, and can result from many dissimilar issues.

Many cheers to "The Guy with The Chapeau" from the Arduino Stack Exchange for compiling a dandy list of fixes that we'll walk through in detail here. So permit's outset with our laundry list…

Potential Fixes

Try disconnecting and reconnecting the USB cable. Yep – that elementary!

Your Arduino board should have a reset button on it. Press the reset button and run across if you can upload without the avrdude: stk500_recv() error.

Close the Arduino IDE, and reopen it once more – believe information technology or not, this can work!

Brand sure yous take the correct Arduino lath selected. In the Arduino IDE, get to Tools -> Board, and from the lists select the Arduino board you are using.

Check to brand sure you accept the correct port selected. In the Arduino IDE, go to Tools -> Port and select the port respective to your board. (On a PC it will starting time with COM, on a MAC information technology should start with cu.usb)
- If you're non sure which is the right port, but take note of all the ports listed, disconnect your Arduino board from the USB cablevision, and and so check the port menu once more. Whichever port is missing, is the port your board was Arduino was using.

The Receive (RX) and Transmit (TX) pins on the Arduino (pins 0 and 1) are used when uploading sketches on your Arduino board. If you have any connections to those pins, pull them out before yous upload to the board.

If you have an Arduino shield fastened to your Arduino board, remove the shield and try uploading again. This is related to the concluding footstep, every bit the shield may take a circuit interfering with the transmit and receive pins.

Still getting avrdude: stk500_recv() error?

Fourth dimension to start troubleshooting! If none of the easy stuff works fret! We still have some options to try! What we'll do is attempt to effigy out the point of failure.

Information technology could be the Arduino Board, the calculator, or the USB cable.

Test the USB Cable

Try using a dissimilar USB cable and see if you can upload without the avrdude: stk500_recv() mistake. I know this seems like an unlikely failure point, but you might be surprised how often USB cables fail.

Exam some other Arduino Board

If yous take another Arduino board handy, try uploading a sketch to it. If you get the avrdude: stk500_recv() error over again, then chances are the issue is with the estimator (run across Issue with Computer below).

If you lot are able to upload a sketch to this other Arduino board fine, and so it may be the first Arduino board that is giving y'all the consequence (run across Effect with Arduino below).

Test a unlike Computer

If you accept another computer with the Arduino IDE loaded on it, try using that reckoner to upload a sketch to the Arduino board. Brand sure y'all are trying all the troubleshooting steps above showtime if yous get the avrdude: stk500_recv() mistake!

If you are able to upload to the Arduino, then the issue is likely with the other computer. (see Event with Reckoner below).

If you go the error on this other computer, then the upshot is probable with the Arduino lath (encounter Outcome with Arduino below).

Issue with Computer

Reinstall the Arduino IDE

If y'all find that the outcome is with your computer, endeavour reinstalling the Arduino IDE. It'south actually non that difficult. Merely become to the Arduino website, download the almost recent version of the IDE and install it once more. This doesn't affect your old sketches, which are stored in your sketchbook folder.

Reinstall Drivers

If you are still getting the avrdude: stk500_recv() error, you can check that you have all the drivers installed correctly. These should exist installed automatically when y'all install the Arduino IDE, but you tin can ever try installing them manually. As well, if y'all take an Arduino clone, sometimes those require special drivers (check the company that makes the boards for where you lot might observe them).

Effect with Arduino:

This is where things get a little dicey. Information technology may be that your Arduino lath is bricked (which is electronics speak for broken in a manner that does not allow fixing).

Check microcontroller seated properly

If you have an Arduino board that has a removable microcontroller chip, similar the Arduino UNO, you tin check to see if it is seated properly on the circuit board.

Perhaps it'due south the Bootloader

It may be that the bootloader (a program on the microcontroller that allows your sketches to run) is having an result. You could burn a new bootloader on the microcontroller.

Have a spare microcontroller?

If the failed lath in question is an Arduino with a removable microcontroller, you could ever bandy out another microcontroller if you accept one handy. You'd take to load the microcontroller with the bootloader (see previous step).
