Useful tip: If you’re unsure of the correct port, take note of all the ports you have listed. Make sure you have the correct port selected: In the Arduino IDE, go to Tools>Port and select the port corresponding to your board.Make sure you have the right Arduino board selected: In the Arduino IDE, go to Tools> Board, and select the Arduino board you’re using from the list.Close and reopen the Arduino IDE: Giving the Arduino IDE a fresh start can fix a host of problems avrdude stk500_recv errors included.Press the reset button: If your Arduino board has a reset button on it, press it and see if you can now upload without the avrdude: stk500_recv() error.Disconnect and reconnect the USB cable: I told you we’d start simple.(Many thanks to “The Guy with The Hat” from the Arduino Stack Exchange for compiling this great list of fixes.) I’ll walk through each in detail, starting at the most common and easiest and moving on to more detailed troubleshooting tasks if those don’t work.īefore we touch on some of the more elaborate and involved potential solutions, it’s smart to rule out all those obvious and small glitches. In this lesson, I’m going to go through a “laundry list” of possible solutions. This generic error can pop up for a host of reasons.īut don’t worry, I’ve got your back.
The avrdude: stk500_recv() error message is alerting you to a generic connection error between your computer and the Arduino. I wish I could keep it simple and tell you this error happens because of one single problem, but that would be too easy. So that’s who the dude is, but why does the error happen? The utility’s main job is pretty straightforward - it allows you to load code onto your Arduino board. So who is this AVR dude, and why does the error happen?ĪVRDude stands for AVR Downloader Uploader and is a utility used by the Arduino IDE.
Or, to be less poetic, you’ll learn how to get rid of this error so you can get back to uploading your sketch.
In this quick lesson, you’ll learn how to banish the mysterious AVR dude to the dusty highways of the nether realms.
Is this some kind of joke? Who is this mysterious AVR Dude, why is he so uncool, and - most importantly - what does he have against you trying to upload a sketch to your Arduino? It’s beyond frustrating. Ever stumbled across this error message when trying to upload a sketch?Īvrdude: stk500_recv(): programmer is not respondingĪvrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00
