Avrdude Problems When Uploading Avrdude Problems When Uploading Arduino Uno
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00
Is this some kind of joke? Who is AVR Dude, and what does he take against me trying to upload a sketch to my Arduino? If you lot're getting this error when trying to upload code to your Arduino board – it can be Actually frustrating!
I wish I could say this happens because of 1 single trouble – simply this fault pops upwardly for many reasons… In this lesson nosotros are going to become through a "laundry list" of possible solutions. Nosotros'll offset at the most common and easiest, and move on to more detailed troubleshooting tasks if those don't work.
Past the end of this lesson, AVR Dude should exist hit the road, and your lawmaking will exist loading on your Arduino board.

Check out our membership plan to learn the software and hardware skills yous'll need to build your ain projects. So who is this avrdude anyway? Well, avrdude is a utility that stands for AVR Download Uploader and when you get this fault, information technology's caused by a generic connexion error between your computer and the Arduino and it can result from many different things. When you run across this mistake, it might feel like y'all've got some programming ghost living within your Arduino IDE. But really, information technology's just basically telling you hey, something is not right when I'm trying to upload code to your Arduino lath. So let's jump in to our list of easy things that might be able to set up this error. All right, the showtime one, simply disconnect and reconnect the USB cable that you're using and so try uploading again. If that doesn't work, effort pressing the reset button on your Arduino board. Then try the upload over again. Okay, if this still isn't working, effort to restarting your Arduino IDE and then run into if you can upload. All right, are you still getting the error? No worries, make certain that you accept the right board selected. And so you wanna get to Tools, Board and make sure that the board at that place's the actual 1 that you're trying to upload your code to. Okay, so you know yous take the right lath selected just you lot're all the same getting the error. Okay, then you've checked the USB cablevision, you tried resetting the board, y'all've restarted the Arduino IDE, yous made certain that you lot had the right lath selected but yous're however getting the avrdude error. Now information technology'due south fourth dimension to make sure that you've got the right port selected. And so to find the port, y'all become to Tools, Serial Port and you select the port. Now, if you don't know which one is the correct port, hither'south a quick fashion to figure that out. And then await at that port list. And and then disconnect the USB cablevision, go to Tools, Serial Port, so see which ports are listed. It could be com4, com5, something along that line if you're on a PC or USB something if you're on a Mac. Then reconnect the USB cable. Now go dorsum to Tools, Series Port and run into which port has appeared that wasn't there before. So that'southward gonna be the port that your Arduino's using. Select that port and try uploading once again. Now, if you're all the same getting the avrdude error, here's the last piece of cake matter you can attempt. Make sure that digital pins nix and one do not accept any parts connected, including any shields. These are the transmit and receive pins on most Arduino boards and if you have something continued there, it tin can interfere with uploading code to your Arduino board. Now, if you have tried all of these steps and avrdude is even so giving you trouble, it's time for u.s.a. to start doing some troubleshooting. What we're gonna endeavour to do is isolate the issue by replacing things. The problem could exist with the computer yous're using, the problem could be with the Arduino board yous're using. Or the problem might be with the USB cable that yous're using. Let's starting time with the USB cable. Simply switch information technology out with another 1. Now, you lot might exist similar actually? The USB cablevision? How likely is that? Well, you lot might be surprised how often these things fail. And by trying a unlike one, yous know that you'll accept ruled that out. So let's say it's not the USB cable. Now what y'all'll wanna practice is cheque if the issue is with the figurer. If you take another Arduino board handy, try uploading a sketch to that other Arduino lath. If you're able to upload a sketch, that tells you lot that the first Arduino board you tried may have the issue. Or if you have another reckoner handy with your Arduino IDE installed on it, endeavor taking the Arduino lath that wouldn't upload the sketch and try uploading a sketch using that other figurer. If yous're able to upload a sketch, that might tell y'all the estimator'south giving you lot the trouble. So if you decide that the issue is with the computer, first try reinstalling the Arduino IDE. Make sure to run through all those checks that we had at the outset, all those easy steps. If y'all're still getting the avrdude error, then attempt reinstalling the drivers. Now, if the upshot was with the specific Arduino board, information technology gets a little more difficult. If you take an Arduino board where the microcontroller can come up out of the lath, like an Arduino Uno, for example, make certain that that microcontroller is seated correctly. If that doesn't fix the mistake, you may need to burn the bootloader back onto the microcontroller. At present, that'southward across the scope of this lesson but I'll make sure to have a link in the description for you to learn how to practise that. But if those aren't working, it could exist that your Arduino lath has been bricked. That is it's just not gonna work anymore, which is unfortunate merely I definitely recommend trying all the troubleshooting steps a couple more times earlier you surrender. Well, I hope one of these helped solve your trouble and avrdude has left you alone. Nosotros'll just run through those like shooting fish in a barrel tips again one more time. You lot wanna try disconnecting and reconnecting your USB cablevision. Yous can try pressing the reset button. You can try restarting the Arduino IDE. You lot wanna double check that you've got the right board selected in the Arduino IDE. You wanna make certain that you lot take the right port selected. And you wanna brand sure digital pins zilch or 1, the receive and transmit pins, don't have annihilation connected to them, including any shields. Well, hey, I promise you accept a fantastic day. Thanks a ton for watching and I await forwards to seeing you adjacent time. Bye. (lively music)
So who is this AVR dude and what is avrdude: stk500_recv() fault?
AVRDude is a utility used by the Arduino IDE. Information technology stands for AVR Downloader Uploader and it allows y'all to load your code onto your Arduino board. The avrdude: stk500_recv() error is caused by a generic connection error between your computer and the Arduino, and tin can result from many different bug.
Many cheers to "The Guy with The Hat" from the Arduino Stack Commutation for compiling a great list of fixes that we'll walk through in item hither. So let's start with our laundry listing…
Potential Fixes
- Endeavour disconnecting and reconnecting the USB cable. Yep – that simple!
- Your Arduino board should have a reset button on it. Press the reset button and see if you can upload without the avrdude: stk500_recv() mistake.
- Close the Arduino IDE, and reopen it once again – believe it or not, this can work!
- Make sure you have the correct Arduino board selected. In the Arduino IDE, go to Tools -> Board, and from the lists select the Arduino board you are using.
- Check to make certain you have the correct port selected. In the Arduino IDE, get to Tools -> Port and select the port corresponding to your board. (On a PC it will start with COM, on a MAC it should starting time with cu.usb)
- If you're non sure which is the correct port, but accept annotation of all the ports listed, disconnect your Arduino lath from the USB cable, and then check the port menu once more. Whichever port is missing, is the port your lath was Arduino was using.
- The Receive (RX) and Transmit (TX) pins on the Arduino (pins 0 and i) are used when uploading sketches on your Arduino board. If y'all have any connections to those pins, pull them out before you lot upload to the board.
- If you take an Arduino shield fastened to your Arduino board, remove the shield and endeavor uploading again. This is related to the terminal step, equally the shield may accept a circuit interfering with the transmit and receive pins.
Withal getting avrdude: stk500_recv() error?
Fourth dimension to start troubleshooting! If none of the easy stuff works fret! Nosotros still take some options to effort! What we'll do is try to effigy out the point of failure.
It could exist the Arduino Board, the computer, or the USB cablevision.
Exam the USB Cable
Endeavor using a different USB cablevision and come across if you can upload without the avrdude: stk500_recv() fault. I know this seems like an unlikely failure point, but you lot might be surprised how oftentimes USB cables fail.
Test another Arduino Board
If you accept another Arduino board handy, try uploading a sketch to information technology. If you get the avrdude: stk500_recv() error again, then chances are the issue is with the computer (run across Issue with Computer below).
If you lot are able to upload a sketch to this other Arduino board fine, so it may exist the commencement Arduino lath that is giving you lot the upshot (meet Issue with Arduino below).
Test a different Calculator
If you lot have some other calculator with the Arduino IDE loaded on it, try using that computer to upload a sketch to the Arduino lath. Brand certain you are trying all the troubleshooting steps above kickoff if you lot get the avrdude: stk500_recv() error!
If yous are able to upload to the Arduino, then the upshot is likely with the other computer. (see Issue with Computer below).
If you lot get the error on this other computer, then the result is likely with the Arduino lath (see Issue with Arduino below).
Upshot with Estimator
Reinstall the Arduino IDE
If you find that the issue is with your figurer, try reinstalling the Arduino IDE. It's really not that hard. Simply go to the Arduino website, download the nearly contempo 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 lot are still getting the avrdude: stk500_recv() mistake, you can bank check that you accept all the drivers installed correctly. These should be installed automatically when you install the Arduino IDE, but you can always try installing them manually. As well, if yous have an Arduino clone, sometimes those require special drivers (cheque the company that makes the boards for where you might find them).
Outcome with Arduino:
This is where things get a niggling dicey. It may be that your Arduino board is bricked (which is electronics speak for broken in a mode 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, you tin check to encounter if it is seated properly on the circuit board.
Perhaps information technology'south the Bootloader
It may be that the bootloader (a program on the microcontroller that allows your sketches to run) is having an issue. You could burn a new bootloader on the microcontroller.
Have a spare microcontroller?
If the failed board in question is an Arduino with a removable microcontroller, y'all could e'er swap out another microcontroller if you have ane handy. You'd have to load the microcontroller with the bootloader (see previous step).
The Battle Continues
Well – I hope later on trying some of these steps you have finally vanquished the avrdude: stk500_recv() fault.
If not, let us know in the comments, or if you find a fix not listed hither please let united states know as well!
