Select Build Project. You will see a progress bar like the one shown here.
The first build will take a while, since it has to unpack a couple of libraries
(Atmel Software Framework, Mercury API). Subsequent builds should be
faster.
The Console tab at the bottom will display all the build output as it comes
along. If you want a bigger view, double-click the Console tab title to
maximize that window. Double-click again to restore.
At the end of a successful build, you should see these messages in the
console:
Finished building target: xPRESS_sam3s8c_flash
12:19:24 Build Finished (took 20s.320ms)
