What is[edit | edit source]
Major software components of an embedded linux system are:
- bootloader
- operating system kernel
- root file system, including user-space application and libraries
- tool chain (on development host)
Naon Embedded Linux Kit (NELK for short) provides all the necessary stuff required to set up the developing environment to:
- build the bootloader (U-Boot)
- build and run Linux operating system on Naon-based systems
- build Linux applications that will run on the target.
The kit is composed by: 1. hardware platform composed by Naon system-on-module (SOM for short) and carrier board. Supported carrier boards are:
- DDS
- NADP (coming soon)
to evaluate Lizard capabilities avoiding to wait for manufacturing of a custom host board. For more details please refer to [1]. 2. U-Boot bootloader sources 3. Linux kernel 2.6.x sources 4. Technical documentation – hardware manuals, mechanical drawings, schematics, software manuals and application notes. The documentation related to the software helps the user to quickly start and configure the bootloader and the operating system. For more details about technical characteristics of processor modules, please see Lizard Hardware Manual ([2]). All the files (sources, documentation etc.) may or may not be delivered on physical media (CDROM or USB memory stick) depending on the purchase order code. However they are always available on-line on our web site. Access to these files is granted to registered kit owner's only.
What is not[edit | edit source]
Introduction[edit | edit source]
The Naon Embedded Linux Kit is directly derived Linux EZ Software Development Kit (EZSDK) provided by Texas Instruments (see TI Website and in TI wiki)
Dave adds to the latest EZSDK the customization required to support Dave's platforms (e.g. Naon)
For this reason most of the documentation provided by TI itself is valid in the SDK provided by us too. Anyway some customization is required
Overview of NELK[edit | edit source]
NELK contains all the required software to develop Linux application on Naon platform:
- u-boot bootloader source code and pre-build binaries
- Linux kernel source code and pre-build binaries
- pre-build OMX libraries (most OMX source code is under NDA from TI)
- gstreamer source code
- sample development (huge!) root file system
- sample production (small enough to fit Naon on-board storage) root file system
- tools and utilities
HowTo Build[edit | edit source]
Generally speaking, if you are using Dave Virtual Development Kit building the whole kit is a matter of:
- startup and login into the virtual machine
- enter the right directory
- execute
make all && sudo make install
The make all command will build all the components of the development kit (e.g. U-Boot binaries, Linux kernel, custom libraries and utilities) and install them into the root file system.
