Problem Uploading to Board Arduino Uno Mac
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() endeavor ane of ten: not in sync: resp=0x00
Is this some kind of joke? Who is AVR Dude, and what does he have confronting me trying to upload a sketch to my Arduino? If yous're getting this fault when trying to upload code to your Arduino board – it can be Really frustrating!
I wish I could say this happens because of one unmarried problem – but this fault pops up for many reasons… In this lesson nosotros are going to go through a "laundry list" of possible solutions. We'll offset at the most common and easiest, and move on to more detailed troubleshooting tasks if those don't work.
By the cease of this lesson, AVR Dude should be hitting the route, and your code will be loading on your Arduino board.

Check out our membership program to learn the software and hardware skills you'll demand to build your own projects. And then who is this avrdude anyway? Well, avrdude is a utility that stands for AVR Download Uploader and when you get this error, it's caused past a generic connection error betwixt your computer and the Arduino and it can result from many dissimilar things. When you meet this error, information technology might feel like you've got some programming ghost living inside your Arduino IDE. But really, information technology'due south just basically telling yous hey, something is not right when I'one thousand trying to upload code to your Arduino board. So let's spring in to our list of piece of cake things that might exist able to fix this error. All right, the first 1, just disconnect and reconnect the USB cable that you're using and then try uploading once more. If that doesn't work, try pressing the reset push button on your Arduino lath. And then try the upload once again. Okay, if this still isn't working, endeavor to restarting your Arduino IDE then run across if yous can upload. All right, are you still getting the error? No worries, brand certain that you have the right lath selected. So you wanna go to Tools, Board and make sure that the board at that place's the actual one that you're trying to upload your code to. Okay, so you know you have the right board selected only yous're still getting the error. Okay, so you've checked the USB cablevision, y'all tried resetting the board, yous've restarted the Arduino IDE, you lot made sure that you had the right board selected but you're all the same getting the avrdude fault. Now it's fourth dimension to brand sure that you've got the right port selected. So to find the port, y'all go to Tools, Serial Port and y'all select the port. At present, if you don't know which one is the correct port, here's a quick way to figure that out. And then look at that port listing. And then disconnect the USB cable, get to Tools, Series Port, and then see which ports are listed. Information technology could be com4, com5, something forth that line if yous're on a PC or USB something if yous're on a Mac. Then reconnect the USB cable. Now become back to Tools, Serial Port and run across which port has appeared that wasn't there earlier. Then that's gonna be the port that your Arduino's using. Select that port and effort uploading once more. Now, if yous're still getting the avrdude error, hither'south the last easy thing you tin can try. Brand sure that digital pins zero and one exercise not have any parts connected, including whatever shields. These are the transmit and receive pins on nigh Arduino boards and if you have something connected there, information technology can interfere with uploading code to your Arduino board. Now, if you have tried all of these steps and avrdude is however giving you lot trouble, it's time for us to starting time doing some troubleshooting. What nosotros're gonna attempt to do is isolate the event past replacing things. The problem could be with the reckoner you're using, the problem could exist with the Arduino board you're using. Or the problem might exist with the USB cable that you're using. Let's start with the USB cable. Just switch it out with another one. Now, you might exist similar actually? The USB cablevision? How likely is that? Well, yous might exist surprised how often these things neglect. And by trying a different i, you know that yous'll have ruled that out. And then allow's say information technology's not the USB cablevision. Now what you'll wanna do is cheque if the issue is with the calculator. If you take 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 first Arduino board you tried may accept the issue. Or if you lot have another computer handy with your Arduino IDE installed on it, try taking the Arduino board that wouldn't upload the sketch and endeavour uploading a sketch using that other computer. If yous're able to upload a sketch, that might tell you the computer'south giving you the trouble. So if you determine that the outcome is with the figurer, outset try reinstalling the Arduino IDE. Make sure to run through all those checks that we had at the starting time, all those easy steps. If you're withal getting the avrdude mistake, then attempt 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 up out of the lath, similar an Arduino Uno, for example, make sure that that microcontroller is seated correctly. If that doesn't set the error, you may demand to burn down the bootloader back onto the microcontroller. At present, that's beyond the scope of this lesson but I'll make sure to have a link in the description for you to learn how to do that. But if those aren't working, it could exist that your Arduino board has been bricked. That is it's just not gonna piece of work anymore, which is unfortunate only I definitely recommend trying all the troubleshooting steps a couple more times before you give up. Well, I promise ane of these helped solve your problem and avrdude has left y'all alone. We'll just run through those easy tips once again one more than time. You wanna effort disconnecting and reconnecting your USB cable. You tin can try pressing the reset button. You can try restarting the Arduino IDE. You wanna double check that you've got the right lath selected in the Arduino IDE. Yous wanna brand certain that you have the correct port selected. And you lot wanna make 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 day. Cheers a ton for watching and I await forrad to seeing you side by side fourth dimension. Bye. (lively music)
So who is this AVR dude and what is avrdude: stk500_recv() error?
AVRDude is a utility used past the Arduino IDE. Information technology 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 error between your calculator and the Arduino, and tin can consequence from many different problems.
Many thanks to "The Guy with The Hat" from the Arduino Stack Commutation for compiling a bully list of fixes that we'll walk through in detail here. So let'due south start with our laundry list…
Potential Fixes
- Try disconnecting and reconnecting the USB cable. Aye – that simple!
- Your Arduino board should have a reset button on it. Printing the reset button and see if you can upload without the avrdude: stk500_recv() error.
- Shut the Arduino IDE, and reopen it again – believe it or not, this tin can work!
- Brand sure you take the right Arduino board selected. In the Arduino IDE, go to Tools -> Board, and from the lists select the Arduino board you are using.
- Bank check to make sure y'all have the correct port selected. In the Arduino IDE, go to Tools -> Port and select the port corresponding to your lath. (On a PC information technology will start with COM, on a MAC information technology should first with cu.usb)
- If you're not sure which is the right port, but have note of all the ports listed, disconnect your Arduino board from the USB cable, so check the port menu once again. 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 you 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 final step, as the shield may have 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 have some options to effort! What nosotros'll do is try to effigy out the point of failure.
Information technology could be the Arduino Board, the estimator, or the USB cable.
Test the USB Cablevision
Attempt using a unlike USB cablevision and run into 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.
Test another Arduino Board
If yous take another Arduino board handy, try uploading a sketch to it. If you get the avrdude: stk500_recv() error again, so chances are the outcome is with the computer (run into Issue with Figurer below).
If you are able to upload a sketch to this other Arduino lath fine, so information technology may be the offset Arduino board that is giving you the upshot (see Issue with Arduino below).
Exam a dissimilar Computer
If you lot accept another computer with the Arduino IDE loaded on it, try using that calculator to upload a sketch to the Arduino board. Make certain you are trying all the troubleshooting steps in a higher place first if you get the avrdude: stk500_recv() error!
If y'all are able to upload to the Arduino, so the event is likely with the other computer. (see Issue with Reckoner below).
If you go the error on this other figurer, then the issue is likely with the Arduino board (run into Upshot with Arduino below).
Event with Computer
Reinstall the Arduino IDE
If you lot find that the issue is with your computer, endeavour reinstalling the Arduino IDE. It's actually not that hard. But go to the Arduino website, download the well-nigh recent version of the IDE and install it once again. 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() error, yous can bank check that you lot accept all the drivers installed correctly. These should be installed automatically when y'all install the Arduino IDE, just you can ever try installing them manually. Also, if y'all have an Arduino clone, sometimes those require special drivers (check the company that makes the boards for where y'all might find them).
Issue 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 manner that does non allow fixing).
Check microcontroller seated properly
If you have an Arduino board that has a removable microcontroller chip, similar the Arduino UNO, y'all tin can bank check to see if it is seated properly on the circuit board.
Peradventure information technology'southward the Bootloader
It may be that the bootloader (a program on the microcontroller that allows your sketches to run) is having an upshot. 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 ever bandy out another microcontroller if you accept 1 handy. You'd have to load the microcontroller with the bootloader (see previous footstep).
The Battle Continues
Well – I hope later on trying some of these steps you have finally vanquished the avrdude: stk500_recv() error.
If not, let u.s. know in the comments, or if yous find a fix non listed here please let u.s.a. know as well!
