Cant Upload to Arduino Uno Get Sync() Brick
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 have against me trying to upload a sketch to my Arduino? If yous're getting this mistake when trying to upload code to your Arduino lath – it can be Actually frustrating!
I wish I could say this happens because of 1 single problem – merely this error pops upwards for many reasons… In this lesson we are going to go through a "laundry list" of possible solutions. We'll start at the most common and easiest, and move on to more detailed troubleshooting tasks if those don't work.
By the end of this lesson, AVR Dude should exist hitting the road, and your lawmaking will exist loading on your Arduino lath.

Check out our membership program to learn the software and hardware skills you'll demand to build your own projects. And so who is this avrdude anyway? Well, avrdude is a utility that stands for AVR Download Uploader and when you lot go this error, it's caused past a generic connectedness error betwixt your computer and the Arduino and it can event from many different things. When yous meet this fault, it might feel like you've got some programming ghost living inside your Arduino IDE. But really, it's only basically telling you lot hey, something is not correct when I'm trying to upload code to your Arduino board. So let'south jump in to our list of easy things that might be able to fix this error. All right, the first one, just disconnect and reconnect the USB cablevision that you're using and then try uploading once more. If that doesn't work, try pressing the reset push on your Arduino board. Then try the upload again. Okay, if this still isn't working, effort to restarting your Arduino IDE and so encounter if you can upload. All right, are you still getting the error? No worries, make sure that you accept the correct board selected. So you wanna get to Tools, Board and brand sure that the board there's the bodily one that you're trying to upload your code to. Okay, so you lot know you lot have the correct board selected but you lot're nevertheless getting the error. Okay, so you've checked the USB cablevision, you tried resetting the board, you lot've restarted the Arduino IDE, you made sure that you had the right board selected just you're still getting the avrdude error. At present information technology's time to make sure that you've got the right port selected. Then to notice the port, you go to Tools, Serial Port and you select the port. Now, if you don't know which 1 is the right port, hither's a quick way to figure that out. So look at that port list. And then disconnect the USB cablevision, go to Tools, Series Port, and so meet 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. And so reconnect the USB cable. At present go back to Tools, Serial Port and run into which port has appeared that wasn't at that place before. And then that's gonna exist the port that your Arduino's using. Select that port and effort uploading again. Now, if you lot're still getting the avrdude mistake, hither's the last piece of cake thing you tin endeavour. Make certain that digital pins zero and one do not have any parts continued, including any shields. These are the transmit and receive pins on most Arduino boards and if you have something connected there, it can interfere with uploading lawmaking to your Arduino board. Now, if y'all take tried all of these steps and avrdude is still giving yous trouble, it'south time for us to offset doing some troubleshooting. What we're gonna try to do is isolate the event by replacing things. The problem could exist with the computer yous're using, the problem could be with the Arduino board you're using. Or the trouble might be with the USB cable that you lot're using. Let's start with the USB cable. Just switch it out with another one. Now, you might be similar really? The USB cable? How likely is that? Well, you might be surprised how often these things fail. And past trying a different one, you lot know that you lot'll have ruled that out. So let's say it's not the USB cable. Now what you'll wanna practice is cheque if the result is with the computer. If y'all have some other Arduino board handy, endeavor uploading a sketch to that other Arduino board. If y'all're able to upload a sketch, that tells you lot that the get-go Arduino board you tried may take the outcome. Or if you accept another estimator handy with your Arduino IDE installed on it, endeavour 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 reckoner's giving you the problem. Then if you determine that the issue is with the figurer, kickoff attempt 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, and then try reinstalling the drivers. At present, if the event was with the specific Arduino board, it gets a little more hard. If you have an Arduino board where the microcontroller can come out of the lath, similar an Arduino Uno, for example, make certain that that microcontroller is seated correctly. If that doesn't fix the fault, you lot may need to burn the bootloader back onto the microcontroller. Now, that's beyond the scope of this lesson just I'll brand sure to have a link in the description for yous to learn how to exercise that. Merely if those aren't working, it could be that your Arduino board has been bricked. That is it'south merely not gonna work anymore, which is unfortunate but I definitely recommend trying all the troubleshooting steps a couple more times before you give up. Well, I hope ane of these helped solve your problem and avrdude has left you alone. Nosotros'll just run through those piece of cake tips again one more time. You wanna try disconnecting and reconnecting your USB cable. You lot tin try pressing the reset button. You can attempt restarting the Arduino IDE. You wanna double check that you've got the right board selected in the Arduino IDE. You lot wanna make certain that you have the right port selected. And you wanna brand certain digital pins naught or one, the receive and transmit pins, don't have annihilation connected to them, including any shields. Well, hey, I hope you lot have a fantastic day. Thanks a ton for watching and I look forwards to seeing you adjacent time. Goodbye. (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 lot to load your code onto your Arduino board. The avrdude: stk500_recv() error is caused by a generic connection fault between your computer and the Arduino, and tin result from many dissimilar issues.
Many thanks to "The Guy with The Hat" from the Arduino Stack Exchange for compiling a great list of fixes that we'll walk through in detail hither. So let's start with our laundry list…
Potential Fixes
- Try disconnecting and reconnecting the USB cable. Yes – that elementary!
- Your Arduino board should accept a reset button on it. Printing the reset button and run across if you can upload without the avrdude: stk500_recv() error.
- Close the Arduino IDE, and reopen it again – believe information technology or non, this can work!
- Brand sure you have the right Arduino board selected. In the Arduino IDE, go to Tools -> Lath, and from the lists select the Arduino board you are using.
- Check to make sure you lot have the correct port selected. In the Arduino IDE, go to Tools -> Port and select the port corresponding to your board. (On a PC it will start with COM, on a MAC it should commencement with cu.usb)
- If y'all're not sure which is the right port, simply have note of all the ports listed, disconnect your Arduino board from the USB cable, and then check the port card once 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 ane) are used when uploading sketches on your Arduino board. If yous accept any connections to those pins, pull them out before you upload to the lath.
- If you lot have an Arduino shield fastened to your Arduino board, remove the shield and attempt uploading once again. This is related to the last step, every bit the shield may have a circuit interfering with the transmit and receive pins.
However getting avrdude: stk500_recv() error?
Fourth dimension to beginning troubleshooting! If none of the easy stuff works fret! We however take some options to attempt! What we'll practice is attempt to effigy out the betoken of failure.
Information technology could be the Arduino Board, the computer, or the USB cable.
Test the USB Cable
Attempt using a unlike USB cable and see if yous tin upload without the avrdude: stk500_recv() mistake. I know this seems like an unlikely failure indicate, but you might be surprised how ofttimes USB cables fail.
Test another Arduino Lath
If you have some other Arduino board handy, attempt uploading a sketch to information technology. If you get the avrdude: stk500_recv() fault again, then chances are the issue is with the estimator (see Event with Computer below).
If you are able to upload a sketch to this other Arduino board fine, then it may be the first Arduino board that is giving you the issue (run across Issue with Arduino beneath).
Examination a different Computer
If you have another computer with the Arduino IDE loaded on it, endeavor using that computer to upload a sketch to the Arduino board. Make sure yous are trying all the troubleshooting steps higher up first if yous get the avrdude: stk500_recv() error!
If you lot are able to upload to the Arduino, so the result is probable with the other calculator. (see Event with Calculator below).
If y'all get the fault on this other computer, then the issue is probable with the Arduino board (see Result with Arduino below).
Issue with Figurer
Reinstall the Arduino IDE
If you discover that the event is with your computer, endeavour reinstalling the Arduino IDE. It's really not 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 old sketches, which are stored in your sketchbook folder.
Reinstall Drivers
If you are still getting the avrdude: stk500_recv() error, you lot tin can check that you have all the drivers installed correctly. These should be installed automatically when you install the Arduino IDE, just yous can always effort installing them manually. Likewise, if yous take an Arduino clone, sometimes those crave special drivers (check the company that makes the boards for where y'all might notice them).
Consequence with Arduino:
This is where things get a little 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 y'all take an Arduino board that has a removable microcontroller chip, similar the Arduino UNO, you can cheque to see if it is seated properly on the excursion 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 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 have one handy. You'd have to load the microcontroller with the bootloader (meet previous footstep).
The Boxing Continues
Well – I hope after trying some of these steps you take finally vanquished the avrdude: stk500_recv() error.
If non, let us know in the comments, or if you detect a prepare not listed hither please let u.s. know equally well!
