Arduino Please Select a Port Before Upload
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() effort one of 10: non 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 can be Actually frustrating!
I wish I could say this happens considering of 1 single problem – just this fault pops up for many reasons… In this lesson we are going to go through a "laundry list" of possible solutions. Nosotros'll start at the nigh common and easiest, and move on to more than detailed troubleshooting tasks if those don't work.
By the finish of this lesson, AVR Dude should be hitting the road, and your code volition be loading on your Arduino lath.

Check out our membership program to larn the software and hardware skills you'll need to build your ain projects. Then who is this avrdude anyway? Well, avrdude is a utility that stands for AVR Download Uploader and when y'all get this error, information technology's caused by a generic connection error betwixt your computer and the Arduino and it can result from many unlike things. When you lot run into this error, it might feel like you've got some programming ghost living inside your Arduino IDE. But really, information technology's but basically telling you lot hey, something is not right when I'g trying to upload code to your Arduino lath. And then allow'south jump in to our list of easy things that might exist able to fix this error. All right, the beginning one, simply disconnect and reconnect the USB cable that you lot're using then try uploading again. If that doesn't work, try pressing the reset button on your Arduino board. Then effort the upload again. Okay, if this withal isn't working, try to restarting your Arduino IDE and then see if you lot tin can upload. All right, are you still getting the mistake? No worries, make certain that you have the correct lath selected. So you wanna go to Tools, Board and make sure that the lath there's the actual one that you lot're trying to upload your code to. Okay, then you know you accept the correct board selected but y'all're still getting the error. Okay, and so you've checked the USB cable, you tried resetting the lath, y'all've restarted the Arduino IDE, you made certain that you had the right board selected only y'all're notwithstanding getting the avrdude error. Now it's fourth dimension to brand sure that you lot've got the right port selected. Then to find the port, you lot go to Tools, Serial Port and you select the port. Now, if you don't know which ane is the correct port, here's a quick way to figure that out. Then await at that port listing. And and then disconnect the USB cable, go to Tools, Series Port, and and then see which ports are listed. It could exist 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 cablevision. Now go back to Tools, Series Port and come across which port has appeared that wasn't at that place earlier. So that'southward gonna be the port that your Arduino'southward using. Select that port and endeavor uploading again. Now, if you're still getting the avrdude mistake, here'south the final easy thing y'all tin try. Make certain that digital pins zero and one practise not take whatever parts connected, including whatever shields. These are the transmit and receive pins on most Arduino boards and if you have something connected at that place, information technology tin can interfere with uploading lawmaking to your Arduino board. Now, if yous have tried all of these steps and avrdude is however giving you trouble, it's fourth dimension for united states to start doing some troubleshooting. What we're gonna effort to practice is isolate the issue past replacing things. The problem could exist with the calculator you're using, the problem could be with the Arduino board y'all're using. Or the problem might be with the USB cablevision that yous're using. Permit's starting time with the USB cable. Just switch it out with another i. Now, you might be like really? The USB cable? How likely is that? Well, you might exist surprised how often these things fail. And by trying a dissimilar i, you lot know that y'all'll have ruled that out. So let'southward say it'southward non the USB cablevision. At present what you'll wanna do is check if the issue is with the figurer. If yous accept another Arduino lath handy, attempt uploading a sketch to that other Arduino lath. If you lot're able to upload a sketch, that tells you that the showtime Arduino board you tried may have the issue. Or if you have another computer handy with your Arduino IDE installed on information technology, endeavor taking the Arduino board that wouldn't upload the sketch and try uploading a sketch using that other computer. If you're able to upload a sketch, that might tell you the computer's giving you the trouble. And then if you determine that the issue 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 like shooting fish in a barrel steps. If you're yet getting the avrdude error, then try reinstalling the drivers. Now, if the issue was with the specific Arduino lath, it gets a petty more difficult. If you lot have an Arduino board where the microcontroller tin come out of the lath, like an Arduino Uno, for instance, make certain that that microcontroller is seated correctly. If that doesn't fix the error, y'all may need to burn the bootloader back onto the microcontroller. Now, that'south across the scope of this lesson but I'll make sure to have a link in the description for you to learn how to exercise that. But if those aren't working, information technology could be that your Arduino board has been bricked. That is information technology's just not gonna work anymore, which is unfortunate just I definitely recommend trying all the troubleshooting steps a couple more times before you give up. Well, I promise one of these helped solve your problem and avrdude has left yous alone. We'll only run through those easy tips again ane more than time. Yous wanna endeavour disconnecting and reconnecting your USB cablevision. Y'all can try pressing the reset button. You can attempt restarting the Arduino IDE. You wanna double check that you've got the right lath selected in the Arduino IDE. Yous wanna make sure that you have the right port selected. And yous wanna make sure digital pins aught or one, the receive and transmit pins, don't have anything connected to them, including whatever shields. Well, hey, I hope y'all have a fantastic day. Cheers a ton for watching and I wait forrad to seeing you next 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 connection fault between your calculator and the Arduino, and tin result from many different issues.
Many cheers to "The Guy with The Hat" from the Arduino Stack Exchange for compiling a slap-up listing of fixes that we'll walk through in detail here. And then permit's start with our laundry listing…
Potential Fixes
- Try disconnecting and reconnecting the USB cable. Yes – that simple!
- Your Arduino lath should accept a reset push button on it. Press the reset button and see if you tin can upload without the avrdude: stk500_recv() fault.
- Close the Arduino IDE, and reopen it again – believe it or not, this can piece of work!
- Make sure yous have the right Arduino lath selected. In the Arduino IDE, become to Tools -> Board, and from the lists select the Arduino board you are using.
- Check 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 information technology will first with COM, on a MAC it should start with cu.usb)
- If you're not sure which is the right port, just take notation of all the ports listed, disconnect your Arduino board from the USB cable, and and then cheque the port menu over again. 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 1) are used when uploading sketches on your Arduino board. If yous have any connections to those pins, pull them out before you upload to the lath.
- If you have an Arduino shield attached to your Arduino board, remove the shield and try uploading again. This is related to the last step, as the shield may take a circuit interfering with the transmit and receive pins.
Still getting avrdude: stk500_recv() fault?
Time to beginning troubleshooting! If none of the like shooting fish in a barrel stuff works fret! Nosotros still have some options to effort! What we'll practise is attempt to figure out the indicate of failure.
It could be the Arduino Board, the calculator, or the USB cable.
Test the USB Cablevision
Try using a unlike USB cable and see if you can upload without the avrdude: stk500_recv() error. I know this seems like an unlikely failure point, but you might be surprised how frequently USB cables fail.
Examination some other Arduino Board
If you have another Arduino lath handy, try uploading a sketch to it. If you get the avrdude: stk500_recv() fault again, and so chances are the issue is with the estimator (see Issue with Calculator below).
If you are able to upload a sketch to this other Arduino board fine, so it may be the commencement Arduino lath that is giving you the upshot (meet Issue with Arduino beneath).
Examination a dissimilar Computer
If yous take another reckoner with the Arduino IDE loaded on it, try using that computer to upload a sketch to the Arduino lath. Make certain y'all are trying all the troubleshooting steps above first if you lot become the avrdude: stk500_recv() error!
If you are able to upload to the Arduino, and then the issue is likely with the other figurer. (come across Issue with Computer below).
If you go the error on this other computer, then the issue is likely with the Arduino board (see Event with Arduino below).
Issue with Calculator
Reinstall the Arduino IDE
If you detect that the issue is with your computer, try reinstalling the Arduino IDE. It's really non that hard. But go to the Arduino website, download the virtually recent version of the IDE and install it once more. This doesn't affect your former sketches, which are stored in your sketchbook folder.
Reinstall Drivers
If you are still getting the avrdude: stk500_recv() error, you can bank check that you lot take all the drivers installed correctly. These should be installed automatically when you lot install the Arduino IDE, but yous can ever try installing them manually. Also, if y'all accept an Arduino clone, sometimes those require special drivers (cheque the visitor that makes the boards for where y'all might observe them).
Issue with Arduino:
This is where things become a lilliputian dicey. It may be that your Arduino board is bricked (which is electronics speak for broken in a manner that does not allow fixing).
Bank check microcontroller seated properly
If you take an Arduino lath that has a removable microcontroller chip, similar the Arduino UNO, y'all tin can check to come across if it is seated properly on the circuit lath.
Perhaps information technology's 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 fire a new bootloader on the microcontroller.
Have a spare microcontroller?
If the failed lath in question is an Arduino with a removable microcontroller, you could always bandy out another microcontroller if you lot take 1 handy. You lot'd have to load the microcontroller with the bootloader (see previous step).
The Boxing Continues
Well – I hope subsequently trying some of these steps you have finally vanquished the avrdude: stk500_recv() mistake.
