Development Environment HowTo (NELK)

Info Box Applies to Naon

Introduction

In this HowTo we'll take a first look of Naon Embedded Linux Kit (NELK) development environment.

To allow fast development startup, NELK is provided as 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 DVDK and, in needed, login by using the default user, start a terminal and:

• cd /home/shared/devel/dave/naon-DAA/sw/linux/sdk/sdk-x.xx.xx.xx
  • 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 make all command

nelk@nelk-desktop:/home/shared/devel/dave/naon-DAA/sw/linux/sdk/sdk-5.03.01.15$ make all
make -C /home/shared/devel/dave/naon-DAA/sw/linux/sdk/sdk-5.03.01.15/board-support/linux-2.6.37-psp04.01.00.06.patch2 ARCH=arm CROSS_COMPILE=/home/shared/devel/dave/naon-DAA/sw/linux/sdk/arm-2009q1//bin/arm-none-linux-gnueabi- uImage

• after the build finish (which may take a while, depending on user's PC power), user can install the binaries with sudo make install (sudo is required due file permission restriction on the root file system)

nelk@nelk-desktop:/home/shared/devel/dave/naon-DAA/sw/linux/sdk/sdk-5.03.01.15$ sudo make install
