Avrdude an Error While Uploading the Sketch
avrdude: stk500_recv(): developer is not responding
avrdude: stk500_getsync() attempt 1 of x: non in sync: resp=0x00
Is this some kind of joke? Who is AVR Dude, and what does he accept 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 – it tin be REALLY frustrating!
I wish I could say this happens because of 1 single problem – but this error pops up for many reasons… In this lesson we are going to go through a "laundry list" of possible solutions. We'll start at the virtually common and easiest, and move on to more detailed troubleshooting tasks if those don't work.
By the finish of this lesson, AVR Dude should be striking the route, and your code will be loading on your Arduino lath.

Check out our membership program to learn the software and hardware skills yous'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, it'due south caused by a generic connexion error betwixt your computer and the Arduino and it tin event from many unlike things. When you see this error, it might feel similar you've got some programming ghost living inside your Arduino IDE. Merely really, it's just basically telling you hey, something is non correct when I'thou trying to upload lawmaking to your Arduino board. Then let's jump in to our list of easy things that might be able to prepare this fault. All right, the first one, but disconnect and reconnect the USB cablevision that you're using and so try uploading once more. If that doesn't work, try pressing the reset push on your Arduino lath. Then try the upload again. Okay, if this all the same isn't working, try to restarting your Arduino IDE and then run into if you lot tin upload. All correct, are you still getting the mistake? No worries, make sure that you accept the right board selected. So you lot wanna get to Tools, Board and make sure that the lath there's the actual one that you're trying to upload your code to. Okay, so yous know you lot have the right board selected only you're still getting the mistake. Okay, so you've checked the USB cable, you tried resetting the lath, you lot've restarted the Arduino IDE, you made sure that you had the right lath selected simply y'all're still getting the avrdude error. Now it's time to brand sure that you've got the correct port selected. And then to find the port, you lot become to Tools, Series Port and y'all select the port. Now, if y'all don't know which one is the correct port, here's a quick style to figure that out. So look at that port listing. And then disconnect the USB cable, go to Tools, Serial Port, and and so run into 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 lot're on a Mac. Then reconnect the USB cable. Now go dorsum to Tools, Serial Port and meet which port has appeared that wasn't in that location before. So that's gonna be the port that your Arduino's using. Select that port and try uploading over again. Now, if y'all're still getting the avrdude error, hither's the last easy affair you tin can try. Brand sure that digital pins nothing and one do not have any parts connected, including whatever shields. These are the transmit and receive pins on virtually Arduino boards and if you lot have something connected in that location, information technology tin interfere with uploading code to your Arduino board. Now, if y'all accept tried all of these steps and avrdude is still giving you trouble, it's time for united states to showtime doing some troubleshooting. What we're gonna try to do is isolate the issue by replacing things. The problem could be with the figurer yous're using, the trouble could be with the Arduino board you're using. Or the problem might be with the USB cable that yous're using. Allow's start with the USB cable. Just switch it out with some other one. At present, you might be like really? The USB cable? How probable is that? Well, you might be surprised how often these things fail. And past trying a unlike one, you know that you'll have ruled that out. So let's say it'due south not the USB cable. Now what yous'll wanna do is check if the issue is with the figurer. If you accept another Arduino lath handy, try uploading a sketch to that other Arduino lath. If you're able to upload a sketch, that tells you that the offset Arduino board y'all tried may have the issue. Or if you take some other estimator handy with your Arduino IDE installed on it, try taking the Arduino lath that wouldn't upload the sketch and endeavor uploading a sketch using that other computer. If yous're able to upload a sketch, that might tell yous the estimator's giving y'all the trouble. So if you make up one's mind that the effect is with the computer, first try reinstalling the Arduino IDE. Make certain to run through all those checks that we had at the beginning, all those easy steps. If you're nonetheless getting the avrdude mistake, and then endeavour reinstalling the drivers. Now, if the issue was with the specific Arduino board, it gets a little more hard. If you have an Arduino board where the microcontroller tin come up out of the board, like an Arduino Uno, for case, make sure that that microcontroller is seated correctly. If that doesn't gear up the error, you may demand to burn the bootloader back onto the microcontroller. Now, that'south beyond the telescopic of this lesson only I'll brand sure to have a link in the clarification for you to learn how to practise that. But if those aren't working, information technology could be that your Arduino board has been bricked. That is it'southward merely non gonna work anymore, which is unfortunate but I definitely recommend trying all the troubleshooting steps a couple more times earlier yous give up. Well, I promise i of these helped solve your problem and avrdude has left you alone. We'll just run through those like shooting fish in a barrel tips again one more time. You wanna try disconnecting and reconnecting your USB cable. You tin try pressing the reset button. You can endeavor restarting the Arduino IDE. You wanna double cheque that you've got the right board selected in the Arduino IDE. You wanna make certain that you take the right port selected. And you wanna make sure digital pins nil or 1, the receive and transmit pins, don't have annihilation connected to them, including any shields. Well, hey, I hope you take a fantastic twenty-four hour period. Thanks a ton for watching and I wait frontwards to seeing you side by side 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. Information technology stands for AVR Downloader Uploader and it allows you to load your code onto your Arduino board. The avrdude: stk500_recv() error is caused by a generic connexion error between your figurer and the Arduino, and tin consequence from many different bug.
Many thank you to "The Guy with The Hat" from the Arduino Stack Exchange for compiling a great list of fixes that nosotros'll walk through in detail hither. Then allow'south kickoff with our laundry list…
Potential Fixes
- Endeavor disconnecting and reconnecting the USB cable. Yes – that uncomplicated!
- Your Arduino board should accept a reset push button on it. Press the reset push and come across if you can upload without the avrdude: stk500_recv() error.
- Close the Arduino IDE, and reopen it again – believe it or not, this can piece of work!
- Make sure you have the right Arduino board selected. In the Arduino IDE, go to Tools -> Board, and from the lists select the Arduino board you lot are using.
- Bank check to make sure you have the right port selected. In the Arduino IDE, become to Tools -> Port and select the port corresponding to your board. (On a PC information technology will start with COM, on a MAC it should start with cu.usb)
- If you're not sure which is the right port, simply have note of all the ports listed, disconnect your Arduino board from the USB cable, and then bank 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 y'all take any connections to those pins, pull them out before you upload to the board.
- If you take an Arduino shield attached to your Arduino board, remove the shield and try uploading again. This is related to the last step, equally the shield may have a circuit interfering with the transmit and receive pins.
Nevertheless getting avrdude: stk500_recv() error?
Time to first troubleshooting! If none of the easy stuff works fret! Nosotros nevertheless accept some options to try! What we'll practise is try to figure out the point of failure.
It could be the Arduino Board, the reckoner, or the USB cable.
Examination the USB Cablevision
Effort using a different USB cable and run into if you can upload without the avrdude: stk500_recv() fault. I know this seems like an unlikely failure bespeak, but you might be surprised how often USB cables fail.
Exam another Arduino Board
If you have another Arduino board handy, try uploading a sketch to it. If you get the avrdude: stk500_recv() fault again, then chances are the issue is with the computer (see Issue with Computer beneath).
If y'all are able to upload a sketch to this other Arduino board fine, then it may be the first Arduino board that is giving you the issue (see Issue with Arduino below).
Test a unlike Computer
If you have another calculator with the Arduino IDE loaded on it, effort using that computer to upload a sketch to the Arduino board. Make sure you are trying all the troubleshooting steps to a higher place first if y'all go the avrdude: stk500_recv() error!
If you are able to upload to the Arduino, then the result is probable with the other computer. (see Issue with Reckoner below).
If y'all go the error on this other figurer, then the upshot is likely with the Arduino lath (see Consequence with Arduino beneath).
Outcome with Estimator
Reinstall the Arduino IDE
If you lot detect that the consequence is with your figurer, endeavour reinstalling the Arduino IDE. It's really not that hard. Just become to the Arduino website, download the most recent version of the IDE and install information technology once again. This doesn't affect your quondam sketches, which are stored in your sketchbook folder.
Reinstall Drivers
If you are even so getting the avrdude: stk500_recv() error, you can check that y'all have all the drivers installed correctly. These should be installed automatically when yous install the Arduino IDE, just yous can always attempt installing them manually. Also, if you have an Arduino clone, sometimes those require special drivers (cheque the company that makes the boards for where you might find them).
Event with Arduino:
This is where things go a trivial dicey. It may exist that your Arduino board 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, like the Arduino UNO, yous can cheque to meet if it is seated properly on the circuit lath.
Mayhap information technology's the Bootloader
Information technology may be that the bootloader (a program on the microcontroller that allows your sketches to run) is having an event. You could burn a new bootloader on the microcontroller.
Take a spare microcontroller?
If the failed lath in question is an Arduino with a removable microcontroller, y'all could always swap out another microcontroller if you accept ane handy. You'd have to load the microcontroller with the bootloader (meet previous footstep).
The Battle Continues
Well – I promise later trying some of these steps you have finally vanquished the avrdude: stk500_recv() error.
If not, allow us know in the comments, or if y'all find a fix not listed here please let us know also!
