user-1: 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.

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.


user3745: In the Arduino IDE, click on Tools (on the menu bar). Then, open the submenu Board and make sure "YUN" is selected.
