Contains executable files for Arm-specific components, such as the compiler, the assembler, the linker and the library tools, and the C-SPY® drivers.

Contains files used for configuring the development environment and projects, for example:

• Linker configuration files (*.icf)

• Special function register description files (*.sfr)

• C-SPY device description files (*.ddf)

• Device selection files (*.i79, *.menu)

• Flash loader applications for various devices (*.out)

• Syntax coloring configuration files (*.cfg)

• Project templates for both application and library projects (*.ewp), and for the library projects, the corresponding library configuration files.
