Can Upload to Arduino Leonardo Programmer Is Not Responding
avrdude: stk500_recv(): programmer is not responding
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 have against 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 Actually frustrating!
I wish I could say this happens because of one 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 movement on to more than detailed troubleshooting tasks if those don't work.
By the finish of this lesson, AVR Dude should exist hitting the road, and your code volition be loading on your Arduino lath.

Check out our membership program to learn the software and hardware skills y'all'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 go this error, information technology's caused by a generic connection fault between your calculator and the Arduino and it can result from many different things. When you see this error, information technology might feel similar you've got some programming ghost living inside your Arduino IDE. But really, information technology'south just basically telling you hey, something is non right when I'yard trying to upload code to your Arduino board. So let's bound in to our list of easy things that might be able to fix this error. All right, the first one, but disconnect and reconnect the USB cable that y'all're using and and then try uploading again. If that doesn't work, try pressing the reset button on your Arduino board. Then effort the upload once again. Okay, if this still isn't working, endeavor to restarting your Arduino IDE and so run into if you tin upload. All correct, are yous still getting the error? No worries, make certain that y'all have the right lath selected. So yous wanna go to Tools, Board and make sure that the board there's the actual one that you're trying to upload your code to. Okay, so you know you accept the correct board selected only yous're still getting the error. Okay, then you lot've checked the USB cable, you tried resetting the board, you've restarted the Arduino IDE, you fabricated sure that you lot had the correct board selected but you're still getting the avrdude fault. Now information technology's time to make sure that you've got the right port selected. So to find the port, yous go to Tools, Serial Port and you select the port. Now, if you don't know which i is the correct port, here'due south a quick way to effigy that out. And so look at that port list. And then disconnect the USB cable, go to Tools, Serial Port, and so 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 you're on a Mac. Then reconnect the USB cable. Now go dorsum to Tools, Series Port and see which port has appeared that wasn't there before. So that'due south gonna be the port that your Arduino's using. Select that port and try uploading again. At present, if you're still getting the avrdude fault, here'southward the last easy thing you can try. Make sure that digital pins zero and i do non have whatever parts connected, including any shields. These are the transmit and receive pins on most Arduino boards and if you lot have something continued there, it tin can interfere with uploading code to your Arduino lath. Now, if you accept tried all of these steps and avrdude is still giving you lot trouble, it's time for us to commencement doing some troubleshooting. What nosotros're gonna try to do is isolate the issue by replacing things. The problem could be with the reckoner you're using, the problem could be with the Arduino lath you're using. Or the problem might be with the USB cable that you're using. Allow's first with the USB cable. But switch it out with another 1. Now, you lot might be similar really? The USB cable? How likely is that? Well, you might be surprised how ofttimes these things neglect. And past trying a different i, you know that you'll have ruled that out. So permit's say it's not the USB cable. Now what y'all'll wanna practise is check if the event is with the estimator. If you have another Arduino board handy, effort uploading a sketch to that other Arduino board. If y'all're able to upload a sketch, that tells you that the get-go Arduino board you lot tried may take the result. Or if you accept another computer handy with your Arduino IDE installed on it, attempt taking the Arduino board that wouldn't upload the sketch and try uploading a sketch using that other calculator. If you're able to upload a sketch, that might tell y'all the computer'due south giving you the trouble. And then 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 nosotros had at the get-go, all those easy steps. If you're however getting the avrdude mistake, then try reinstalling the drivers. Now, if the consequence was with the specific Arduino board, it gets a little more than difficult. If yous have an Arduino lath where the microcontroller tin come out of the board, like an Arduino Uno, for example, make sure that that microcontroller is seated correctly. If that doesn't fix the error, yous may demand to burn the bootloader back onto the microcontroller. Now, that'due south beyond the scope of this lesson but I'll brand sure to have a link in the description for you to learn how to do that. But if those aren't working, it could be that your Arduino board has been bricked. That is it's but not gonna work anymore, which is unfortunate but I definitely recommend trying all the troubleshooting steps a couple more times earlier you give up. Well, I promise one of these helped solve your problem and avrdude has left you lot solitary. We'll just run through those easy tips again one more time. You lot wanna attempt disconnecting and reconnecting your USB cable. You tin can try pressing the reset push. You tin can try restarting the Arduino IDE. You lot wanna double check that you've got the right lath selected in the Arduino IDE. You wanna make sure that you have the right port selected. And you wanna brand certain digital pins zero or 1, the receive and transmit pins, don't have annihilation connected to them, including whatever shields. Well, hey, I hope yous have a fantastic mean solar day. Thanks a ton for watching and I look forward to seeing you next time. Bye. (lively music)
And then who is this AVR dude and what is avrdude: stk500_recv() error?
AVRDude is a utility used past the Arduino IDE. It stands for AVR Downloader Uploader and it allows yous to load your code onto your Arduino board. The avrdude: stk500_recv() fault is acquired past a generic connection error between your calculator and the Arduino, and tin upshot from many different issues.
Many cheers 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. So let's start with our laundry list…
Potential Fixes
- Try disconnecting and reconnecting the USB cablevision. Yes – that unproblematic!
- Your Arduino board should have a reset button on information technology. Press the reset button and see if yous can upload without the avrdude: stk500_recv() error.
- Close the Arduino IDE, and reopen it again – believe it or not, this can work!
- Brand certain y'all have the right Arduino lath selected. In the Arduino IDE, get to Tools -> Board, and from the lists select the Arduino board y'all are using.
- Cheque to make sure you have the correct port selected. In the Arduino IDE, go to Tools -> Port and select the port corresponding to your lath. (On a PC it will start with COM, on a MAC it should get-go with cu.usb)
- If you're not sure which is the right port, simply have notation of all the ports listed, disconnect your Arduino board from the USB cable, and and so check the port bill of fare 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 ane) are used when uploading sketches on your Arduino board. If you have any connections to those pins, pull them out earlier you upload to the board.
- If you have an Arduino shield fastened to your Arduino board, remove the shield and try uploading once more. This is related to the terminal footstep, equally the shield may accept a circuit interfering with the transmit and receive pins.
Still getting avrdude: stk500_recv() error?
Time to outset troubleshooting! If none of the easy stuff works fret! We still have some options to attempt! What we'll do is try to figure out the point of failure.
It could exist the Arduino Board, the estimator, or the USB cable.
Test the USB Cable
Try using a different USB cable and see if you can upload without the avrdude: stk500_recv() error. I know this seems like an unlikely failure bespeak, but you lot might be surprised how often USB cables fail.
Test another Arduino Board
If you accept some other Arduino board handy, try uploading a sketch to it. If you go the avrdude: stk500_recv() error again, then chances are the issue is with the reckoner (see Consequence with Estimator below).
If you are able to upload a sketch to this other Arduino board fine, and so it may exist the showtime Arduino board that is giving you the issue (see Issue with Arduino beneath).
Test a different Calculator
If you have another computer with the Arduino IDE loaded on information technology, 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 you become the avrdude: stk500_recv() mistake!
If you are able to upload to the Arduino, then the issue is probable with the other computer. (come across Issue with Calculator below).
If you get the error on this other calculator, then the issue is likely with the Arduino board (run into Issue with Arduino beneath).
Event with Figurer
Reinstall the Arduino IDE
If you notice that the issue is with your computer, attempt reinstalling the Arduino IDE. It's really non that hard. Simply get to the Arduino website, download the most recent version of the IDE and install it again. This doesn't affect your onetime sketches, which are stored in your sketchbook binder.
Reinstall Drivers
If you are still getting the avrdude: stk500_recv() error, you lot can check that yous have all the drivers installed correctly. These should be installed automatically when y'all install the Arduino IDE, but you tin can e'er try installing them manually. Also, if you have an Arduino clone, sometimes those require special drivers (check the company that makes the boards for where you might find them).
Issue with Arduino:
This is where things go a piddling 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 lath that has a removable microcontroller chip, like the Arduino UNO, you can cheque to run across if it is seated properly on the circuit board.
Perhaps it'south the Bootloader
Information technology may be that the bootloader (a plan 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, you could ever swap out another microcontroller if you lot take one handy. Yous'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() fault.
