<p><b>Overview</b>

|
|
|
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.

|
|
|
|
|
At the top level is the main makefile and a series of sub-directories identified
|
|
|
|
|
below and discussed in the following paragraphs:</p>
