1.0 Introduction

Overview This document provides and overview of the Nuttx build and configuration logic and provides hints for the incorporation of new processor/board archectures into the build.

See also arch/README.txt.

General Philosophy.

2.0 Directory Structure

The general directly layout for Nuttx is very similar to the directory structure of the Linux kernel -- at least at the most superficial layers. At the top level is the main makefile and a series of sub-directories identified below and discussed in the following paragraphs:
