First build

Before you build for the first time, you should have configured both the kernel and your application. This is easiest to do from command line (read the README in the source distribution how that's done).

Now build the application. Keep an eye on the output and make sure the cross-tools you intended to use are really the ones used. In the example above we can verify it's the arm-hix-elf tool-chain thats been used... (this might look slightly different if you use another target tool-chain).

Advice: I usually deselect the "Build automatically"
