Linker Script File
The GNU toolchain requires a linker control file that controls the memory layout. A pre-defined linker control file that fits most systems can be found in the folder \ARM\GNU. Since the file needs to be adapted to your application, you should copy it to your project folder and enter it under Options for Target — Linker. The linker control file is needed to define a memory layout, however it may be omitted for very simple test programs.

Include Paths
List of paths that will be searched to include archive libraries.
Misc controls
