=== Introduction ===
In this [[:Category:HowTo|HowTo]] we'll take a first look of [[:Category:Naon|Naon]] Embedded Linux Kit (NELK) development environment.
To allow fast development startup, NELK is provided as [[:Category:DVDK|DVDK]] virtual appliance, in this way user can setup its development environment in minutes and get productive as soon as the VM starts.
=== Build the whole kit ===
Building the whole kit means:
* build Linux kernel with default configuration
* build u-boot with default configuration
* build gstreamer and all the required libriaries
* install the binaries into the root file system
After starting the [[:Category:DVDK|DVDK]] and, in needed, login by using the default user, start a terminal and:
* <code>cd /home/shared/devel/dave/naon-DAA/sw/linux/sdk/sdk-x.xx.xx.xx</code>
** where the ''x'' should be substituted with the current release which NELK is based (e.g. ''/home/shared/devel/dave/naon-DAA/sw/linux/sdk/sdk-5.03.01.15'')
* run <code>make all</code> command
