Fixed typo in system_fundamentals. Acronyms FIFO and LIFO defined with capital letters in kernel_fundamentals. Added bold to paragraph lists to enhance readability in application_fundamentals Added lots of :dfn: syntax for better interlinking to API. Corrected whitespace for sub-bullet directive.

Application Fundamentals
|
|
########################
|
|
|
|
A Zephyr application is defined by creating a directory containing the
|
|
following files.
|
|
|
|
* **Application source code files**: An application typically provides one
|
|
or more application-specific files, written in C or assembly language. These
|
|
files are usually located in a sub-directory called :file:`src`.
|
|
|
|
* **Kernel configuration files**: An application typically provides a configuration
|
|
file (:file:`.conf`) that specifies values for one or more kernel configuration
|
|
options. If omitted, the application's existing kernel configuration option values
|
|
are used; if no existing values are provided, the kernel's default configuration
|
|
values are used.
|
|
|
|
A microkernel application typically provides an additional :abbr:`Microkernel
|
|
Definitions File (MDEF)` under the extension :file:`.mdef`. This file defines
|
|
all of the system's public microkernel objects. This file is not used with a
|
|
nanokernel-only application.
|
|
|
|
* **Makefile**: This file typically contains a handful of lines that tell the build
|
|
system where to find the files mentioned above, as well as the desired target
|
|
platform configuration and kernel type (either microkernel or nanokernel).
|
|
|
|
Once the application has been defined, it can be built with a single command.
|
|
The results of the build process, including the final application image,
|
|
are located in a sub-directory called :file:`outdir`.
