Build Instructions

Prerequisites

The building process for ISOBlue 2.0 is very customizable. If you do not have similar experience, it is recommended that you read through some of the Yocto project documentations to get started. If you do not have much experience in Linux, you can still download a prebuilt ISOBlue image and follow the flashing instructions to get yourself an ISOBlue.

Machine Requirement

For building an ISOBlue image, a powerful, multi-core host machine is highly recommended. There should be a minimum of 60GB of free disk place, 4GB of RAM and a decent Internet connection. The build procedure is currently only tested on Ubuntu 16.10.

Preparations

ISOBlue's image (which added a bunch of custom recipes on top of Toradex BSP) build requires some additional packages, mainly 32-bit flashing utilities. You need to do:

sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install g++-5-multilib
sudo apt-get install curl dosfstools gawk g++-multilib gcc-multilib lib32z1-dev \
libcrypto++9v5:i386 libcrypto++-dev:i386 liblzo2-dev:i386 lzop libsdl1.2-dev \
libstdc++-5-dev:i386 libusb-1.0-0:i386 libusb-1.0-0-dev:i386 uuid-dev:i386 \
texinfo chrpath
cd /usr/lib; sudo ln -s libcrypto++.so.9.0.0 libcryptopp.so.6

We would also need to install repo for source synchronizations:

sudo apt-get install repo

Source Synchronization

You need to simply do:

mkdir isoblue-core
cd isoblue-core
repo init -u https://github.com/ISOBlue/isoblue-image -b v2.7
repo sync

After getting the ISOBlue image source, you can do:

. export

After sourcing export, you will be put into the build directory with the following items configured for the current session:

  • bitbake executable
  • shell environment variables

You will need to source export again to have the right configurations.

Editing isoblue.conf

Before building the image, edit isoblue.conf under top-level-directory, i.e., isoblue-core in our instruction:

The settings you need to change is the ID and MACHINEID.

  • For ID, you can use any combination from 011 to 999 and this will be your ISOBlue's unique ID (000 to 010 are already taken). This is only a temporary solution and will get changed in the future.
  • For MACHINEID, you can append a string of your choice to the configured ID. The string can only contain letters. The default string is ib.

Building

Given that you are in the build directory, run:

bitbake -r ../isoblue.conf console-isoblue-image

This command reads in the configuration you set in the isoblue.conf earlier and use the settings to build an image. This first build usually takes of hours (it involves a lot of downloading and compiling). Be patient!

After a successful build, you should have the following directory structure for for your deploy directory:

isoblue-oe
└── deploy
│ └── images
│ └── apalis-imx6
│ └── ipk
│ └── licenses

apalis-imx6 is the processor ISOBlue 2.0 is using. The image should be located in the apalis-imx6 folder. The image file we are looking for should be in the format of Isoblue2_apalis-imx6_image_2.7b2-YYYYMMDD.tar.bz2. Copy this file to a directory of your choice and follow the flashing instructions to load the image onto your hardware.
