Introduction

Divelk 01.png

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
    • Build system
    • Pre-built root file systems
  • 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 components

DAVE Embedded Systems adds to the latest AMSDK 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.

The following table shows how DIVELK releases are related to AMSDK or Processor SDK releases.

DIVELK microSD Layout

The microSD card provided with DIVELK is partitioned as shown in the following image:


microSD card partitioning

Most of storage space is occupied by two partitions:

  • a FAT32 partition (mmcblk0p1) containing:
    • U-Boot bootscript
    • Linux kernel and DTB binary images
    • DIVELK virtual machine image in OFV format (MVM basic version)
    • 7-zip Windows executable file
  • an ext3 partition (mmcblk0p2) containing the root file system for the target.

bootscript and root file system are used to boot the target as described in this section.

It is worth remembering that the microSD card is bootable, because U-Boot image files (MLO and u-boot.img) and kernel image (uImage) are present into first FAT32 partition: filename MUST be the one written before.

However, even if U-Boot is run from the microSD card, the environment is retrieved from NOR flash.

How to create a bootable microSD card

For creating a bootable microSD card, simply follows the following steps:

  • create two partition: first partition FAT32 and a second partition ext3
  • mark as "bootable" the first partition (using for example gparted on VM)
  • copy MLO, u-boot.img and boot.scr on FAT32 partition
    • copy kernel and dtb on the same partition
    • all files can be retrieved from here
  • extract rfs on ext3 partition

Quick start guide

This chapter describes how to quickly start working with the DIVELK kit. The following paragraphs will guide you through the setup and installation procedures.

DIVA SOM

Diva-400.png

The heart of DIVA SOM is Texas Instruments "Sitara". From a software point of view, Texas Instruments supports this processor family through so-called Processor Software Development Kit (Processo SDK for short). Processor SDK releases are published on a regular basis. For more details please refer to:

DIVA Embedded Linux Kit, in turn, is directly derived from Processor SDK. Hence DIVELK documentation often refers to this resource.

Carrier boards

DIVAEVB-Lite

DIVAEVB-Lite is an adapter board designed to evaluate the functions of DIVA system-on-module.

Diva-evb-with-som.png

For further information on the DIVAEVB-Lite, please refer to DivaEVB-Lite

The following figure shows the carrier board block diagram:

Divaevb-bd.png

Dacu

DIVAEVB-Lite can be plugged on the Dacu carrier board to extend the set of available interfaces.

For further information on Dacu, please refer to:

The following figure shows the carrier board block diagram:

Kit registration

200px-Emblem-important.svg.png Customers are strongly recommended to register their kits. Registration grants access to reserved material such as source code and additional documentation. 200px-Emblem-important.svg.png

Please register your development kit by sending an email to support-diva@dave.eu, providing the kit P/N and CODE.

Target setup and first boot

This section describes how to quick start DIVA board delivered along with DIVELK kit:

  • connect the DB9 serial cable adapter to J25 pin-strip connector on DACU as shown on picture below
  • insert microSD card in the DACU slot J34
  • optionally connect the system to Ethernet LAN by plugging cable into connector J7
  • on host side start your favorite terminal that will be used to interact with the target's serial console; communication parameters are 115200-8-N-1
  • connect the provided 12V power supply to JP2 DACU connector


Target setup for first boot


Once power has been applied to the target, U-Boot bootloader will be fetched from the SPI NOR flash and executed. Boot messages will be printed out to the serial console. Redundant U-Boot environment is stored in the NOR flash as well, as depicted in the following image.


NOR flash default partitioning


By default, U-Boot is configured to retrieve Linux kernel image stored in the microSD card [1]. In turn, Linux kernel shall mount root file system from the mmcblk0p2 partition of the microSD card itself. At the end of boot process, Linux shell shall be available on the serial console.

The following dump shows the typical messages printed out to the console during bootstrap process.

Host setup

As stated previously, DIVELK host tools are based on a Managed Virtual Machine. As indicated here, microSD card delivered along with DIVELK includes basic version of MVM that is the default option.

In case you choose to use the Advanced version of the MVM instead, the project-name to be used is diva.

Either version you choose, please follow the procedure described here to install the MVM.

It is also worth remembering that access to git repositories is required to download target source code. To enable it, please refer to this page.


200px-Emblem-important.svg.png Either version of MVM is installed, it provides the tools required to build U-boot and Linux kernel. It does not include the tools required to run Yocto build system instead. 200px-Emblem-important.svg.png


DIVELK MVM can be downloaded here. For accessing DIVELK Reserved area please contact our sales department

Target configuration for the development stage (net_nfs)

During the development stage, the target is usually connected via Ethernet LAN to the host machine and is configured to:

  • retrieve binary images (i.e. Linux kernel) via TFTP protocol
  • mount the development root file system via NFS protocol. This root file system is physically in the file system of the host machine as depicted here.

In DAVE Embedded Systems development kits, this configuration is generally denoted as net_nfs. U-Boot bootloader supports this configuration. Some U-Boot environment variables are needed to set it up. They are detailed here.

For more details about TFTP and NFS servers on host side, please refer to this page.

Target configuration for standalone boot

Please refer to this page.

Advanced topics

Debugging with Eclipse

Please refer to this page.
