1.8.8 an Error Occurred While Uploading the Sketch
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 accept against me trying to upload a sketch to my Arduino? If you're getting this error when trying to upload code to your Arduino lath – information technology 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. Nosotros'll starting time at the most common and easiest, and move on to more detailed troubleshooting tasks if those don't work.
By the terminate of this lesson, AVR Dude should exist hitting the road, and your lawmaking will be loading on your Arduino board.

Check out our membership program to learn the software and hardware skills yous'll demand to build your own projects. Then who is this avrdude anyway? Well, avrdude is a utility that stands for AVR Download Uploader and when you get this error, information technology'southward acquired by a generic connexion error betwixt your computer and the Arduino and it tin issue from many different things. When you come across this error, it might experience like you've got some programming ghost living inside your Arduino IDE. Only really, it'south merely basically telling you hey, something is not right when I'm trying to upload code to your Arduino lath. And then let's jump in to our list of easy things that might be able to fix this error. All right, the start one, simply disconnect and reconnect the USB cable that you're using and so endeavour uploading again. If that doesn't work, try pressing the reset button on your Arduino lath. And then try the upload once more. Okay, if this nonetheless isn't working, endeavour to restarting your Arduino IDE and and then see if you tin can upload. All correct, are you nonetheless getting the mistake? No worries, make sure that you have the correct board selected. And so you wanna go to Tools, Board and make certain that the lath there'due south the bodily one that yous're trying to upload your code to. Okay, and so you know you have the right board selected but you're even so getting the error. Okay, so you lot've checked the USB cablevision, you tried resetting the board, y'all've restarted the Arduino IDE, you lot made sure that y'all had the right board selected but you're still getting the avrdude error. Now it's time to make sure that you've got the right port selected. So to detect the port, you go to Tools, Serial Port and you lot select the port. Now, if you don't know which one is the correct port, here'southward a quick mode to effigy that out. So expect at that port list. So disconnect the USB cable, become to Tools, Serial Port, and and so meet which ports are listed. It could be com4, com5, something forth that line if you're on a PC or USB something if you're on a Mac. Then reconnect the USB cable. At present go back to Tools, Serial Port and run across which port has appeared that wasn't there earlier. So that'south gonna be the port that your Arduino'south using. Select that port and endeavour uploading again. Now, if you lot're still getting the avrdude mistake, hither'due south the last piece of cake thing you can try. Make sure that digital pins nil and i practice non have any parts connected, including any shields. These are the transmit and receive pins on most Arduino boards and if you take something connected in that location, information technology tin interfere with uploading code to your Arduino lath. Now, if y'all have tried all of these steps and avrdude is still giving you trouble, information technology's fourth dimension for u.s. to outset doing some troubleshooting. What we're gonna try to do is isolate the issue by replacing things. The problem could be with the computer you're using, the problem could be with the Arduino board y'all're using. Or the problem might exist with the USB cable that you're using. Let's start with the USB cable. Only switch it out with another i. At present, you lot might be like really? The USB cable? How probable is that? Well, you might be surprised how often these things fail. And by trying a unlike one, you lot know that you'll have ruled that out. So permit's say information technology's not the USB cable. Now what you'll wanna practice is bank check if the event 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 start Arduino board yous tried may accept the upshot. Or if y'all have some other computer handy with your Arduino IDE installed on information technology, try taking the Arduino board that wouldn't upload the sketch and attempt uploading a sketch using that other reckoner. If y'all're able to upload a sketch, that might tell you the estimator'southward giving you lot the trouble. So if you determine that the result is with the computer, starting time try reinstalling the Arduino IDE. Make sure to run through all those checks that we had at the beginning, all those easy steps. If you're nevertheless getting the avrdude mistake, so endeavor reinstalling the drivers. Now, if the issue was with the specific Arduino board, it gets a little more difficult. If you have an Arduino board where the microcontroller can come out of the board, similar an Arduino Uno, for example, make sure that that microcontroller is seated correctly. If that doesn't fix the error, y'all may demand to burn the bootloader back onto the microcontroller. Now, that's beyond the telescopic of this lesson but I'll make sure to accept a link in the clarification for yous to learn how to do that. But if those aren't working, information technology could be that your Arduino board has been bricked. That is it'southward simply not gonna piece of work anymore, which is unfortunate but I definitely recommend trying all the troubleshooting steps a couple more times earlier you surrender. Well, I hope one of these helped solve your problem and avrdude has left you alone. We'll just run through those easy tips again one more time. Yous wanna effort disconnecting and reconnecting your USB cablevision. You can try 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. You wanna make sure that yous have the right port selected. And yous wanna brand sure digital pins naught or one, the receive and transmit pins, don't have anything continued to them, including any shields. Well, hey, I hope y'all take a fantastic day. Thanks a ton for watching and I expect forwards to seeing yous next fourth dimension. 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 you lot to load your code onto your Arduino board. The avrdude: stk500_recv() error is caused by a generic connection mistake between your computer and the Arduino, and can result from many different issues.
Many thank you to "The Guy with The Hat" from the Arduino Stack Exchange for compiling a not bad listing of fixes that we'll walk through in detail hither. And then let'southward start with our laundry listing…
Potential Fixes
- Effort disconnecting and reconnecting the USB cablevision. Yeah – that simple!
- Your Arduino board should have a reset push on it. Press the reset push and see if y'all can upload without the avrdude: stk500_recv() error.
- Shut 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 yous are using.
- Check to make sure you take the right port selected. In the Arduino IDE, go 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 yous're not sure which is the correct port, but take note of all the ports listed, disconnect your Arduino lath from the USB cable, so bank check the port carte 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 one) are used when uploading sketches on your Arduino board. If you have whatsoever connections to those pins, pull them out before you upload to the board.
- If y'all take an Arduino shield attached to your Arduino board, remove the shield and try uploading again. This is related to the terminal step, equally the shield may accept a circuit interfering with the transmit and receive pins.
Still getting avrdude: stk500_recv() fault?
Fourth dimension to start troubleshooting! If none of the easy stuff works fret! We notwithstanding take some options to endeavour! What nosotros'll practice is try to figure out the betoken of failure.
It could be the Arduino Lath, the computer, or the USB cable.
Examination the USB Cable
Endeavour using a different USB cable and see if you tin can upload without the avrdude: stk500_recv() error. I know this seems like an unlikely failure point, but yous might exist surprised how frequently USB cables fail.
Test another Arduino Board
If y'all take some other Arduino board handy, try uploading a sketch to it. If yous become the avrdude: stk500_recv() mistake again, then chances are the effect is with the estimator (run across Issue with Figurer below).
If you are able to upload a sketch to this other Arduino board fine, then it may be the offset Arduino board that is giving you lot the issue (see Issue with Arduino below).
Test a unlike Computer
If you have some other computer with the Arduino IDE loaded on it, endeavour using that computer to upload a sketch to the Arduino board. Make sure you are trying all the troubleshooting steps in a higher place start if you become the avrdude: stk500_recv() error!
If yous are able to upload to the Arduino, and so the issue is probable with the other computer. (meet Result with Computer below).
If you get the error on this other computer, then the issue is likely with the Arduino lath (see Upshot with Arduino below).
Issue with Computer
Reinstall the Arduino IDE
If you find that the issue is with your computer, try reinstalling the Arduino IDE. Information technology'south actually not that hard. Simply go to the Arduino website, download the most recent version of the IDE and install information technology again. This doesn't affect your old sketches, which are stored in your sketchbook folder.
Reinstall Drivers
If yous are even so getting the avrdude: stk500_recv() error, you can check that you lot have all the drivers installed correctly. These should exist installed automatically when you install the Arduino IDE, just you can e'er endeavor installing them manually. Also, if you have an Arduino clone, sometimes those require special drivers (check the visitor that makes the boards for where you might find them).
Consequence with Arduino:
This is where things become a little dicey. Information technology may be that your Arduino board is bricked (which is electronics speak for broken in a manner that does not let fixing).
Check microcontroller seated properly
If you have an Arduino lath that has a removable microcontroller scrap, like the Arduino UNO, you can check to see if it is seated properly on the circuit board.
Perhaps it'southward 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.
Take a spare microcontroller?
If the failed board in question is an Arduino with a removable microcontroller, you could always swap out another microcontroller if you accept one handy. You'd have to load the microcontroller with the bootloader (run into previous step).
The Boxing Continues
Well – I hope subsequently trying some of these steps you have finally vanquished the avrdude: stk500_recv() error.
If not, let the states know in the comments, or if you notice a fix not listed here delight let u.s.a. know every bit well!
