I have an Arduino Yun. I am trying to upload the code in Arduino but after I click on Upload, I get the error message shown in the image.

At first it showed the Arduino Yun under the port tab, after this message no Arduino is showing in port tab. enter image description here

The portion of the error visible in the image:

Couldn't find a Board on the selected port. Check that you have the correct port selected. If it is correct, try pressing the board's reset button after initiating the upload.

    It's very hard to read that error, perhaps you could crop it a bit? It's also useful to include the message as text so that it's searchable for anyone else with the same problem in the future.

In the Arduino IDE, click on Tools (on the menu bar). Then, open the submenu Board and make sure "YUN" is selected.


Seems like you havent chose the appropriate serial port.

Under tools, you'll also find serial port - make sure the appropiate one is selected.
