IntroductionEdit
Diva Embedded Linux Kit (DIVELK for short) provides all the necessary components required to set up the developing environment to:
- build the bootloader (U-Boot)
- build and run Linux operating system on Diva-based systems
- build Linux applications that will run on the target.
The main kit components are:
- hardware platform composed by Diva system-on-module (SOM for short) and carrier board. Supported carrier boards are:
- DivaEVB-Lite standalone
- DivaEVB-Lite plugged on Dacu carrier board
- Development virtual machine containing:
- Toolchain
- U-Boot bootloader sources
- Linux kernel sources
- Technical documentation such hardware manuals, mechanical drawings, reference schematics, application notes etc.
The documents related to the software issues help the user to quickly start configuring the bootloader and the operating system, by hiding most of the complexity of the underlying hardware. For more details about Diva hardware characteristics, please refer to the Diva Hardware Manual. An account for the reserved area of DAVE Embedded Systems website is required to access the kit contents.

DIVELK software componentsEdit
DAVE Embedded Systems adds to the latest EZSDK from Texas Instruments the customization required to support the Diva platform. For this reason most of the documentation provided by TI remains valid for the DIVELK development kit. However, some customization is required, in particular at bootloader and linux kernel levels.
