Development Guide
Introduction
This section provides an overview of the areas covered by the documentation,what is
contained, the appropriate readers, the documentation version history, and the
applicable hardware version.
This chapter describes how to run Linux system and embedded Linux applications
and the process of drive development in MYD-AM335X series development board. It
includes building the development environment, compiling the source code,
examples of Linux application and image download.
This document is suitable for embedded Linux development engineers with some
development experience.

Create a working directory:
Create a work directory and copy the resources from 04-Linux_Source of our release
package to the work directory on ubuntu host PC， here is defined by customers
according to their development environment.
$ mkdir -p <WORKDIR>
$ cp /media/cdrom/04-Linux_Source/* <WORKDIR> -rf
$ ls <WORKDIR>
