Build System: It is no longer necessary to have a unique Make.defs file for each configuration. A board may share a common Make.defs file in the scripts directory.

Each board configuration is described by two files: <code>Make.defs</code> and <code>defconfig</code>.
Typically, each set of configuration files is retained in a separate configuration sub-directory
(<i>&lt;config1-dir&gt;</i>, <i>&lt;config2-dir&gt;</i>, .. in the above diagram).
</p>
<p>
NOTE: That the <code>Make.defs</code> file may reside in one of two locations:
There may be a unique Make.defs file for each configuration in the configuration directory <i>OR</i>
if that file is absent, there may be a common board <code>Make.defs</code> file in the <code>/scripts</code> directory.
The <code>Make.defs</code> file in the configuration takes precedence if it is present.

The procedure for configuring NuttX is described <a href="#configuringnuttx">below</a>,
This paragraph will describe the contents of these configuration files.
