If it fails to detect your board (on Windows it would show a black screen) : double click on the reset button, the led should start glowing red and the com port should appear. Re launch Bossa Loader and try again.

To install it, download your version : 

and unzip to any folder before running the executable.

Bossa Uploader is made with Processing as a wrapper to the bossac command line tool ( from http://www.shumatech.com/web/products/bossa ).

You can find the Processing  source code here: https://github.com/deladriere/euro-modules/tree/master/BossaLoader
