VAR-SOM-MX6 - Debian Jessie release

Overview

This page describes how to assemble and install Linaro ALIP distro based on Debian Jessie on Variscite var-som-mx6 SoMs.

This instruction was tested with Debian 8.4 x64 (jessie) and Ubuntu 14.04/16.04 x64! When using other distributions, there may be problems.

Create build environment

Installing required packages

Debian jessie x64

If your system does not have "sudo", set the "sudo" using the link: [1]

On your Debian building machine:

$ sudo apt-get install -y binfmt-support qemu qemu-user-static debootstrap kpartx
$ sudo apt-get install -y lvm2 dosfstools gpart binutils git lib32ncurses5-dev python-m2crypto
$ sudo apt-get install -y gawk wget git-core diffstat unzip texinfo gcc-multilib build-essential chrpath socat libsdl1.2-dev
$ sudo apt-get install -y autoconf libtool libglib2.0-dev libarchive-dev
$ sudo apt-get install -y python-git xterm sed cvs subversion coreutils texi2html bc
$ sudo apt-get install -y docbook-utils python-pysqlite2 help2man make gcc g++ desktop-file-utils libgl1-mesa-dev

Ubuntu 14.04/16.04 x64

On your Ubuntu building machine:

$ sudo apt-get install -y binfmt-support qemu qemu-user-static debootstrap kpartx
$ sudo apt-get install -y lvm2 dosfstools gpart binutils git lib32ncurses5-dev python-m2crypto
$ sudo apt-get install -y gawk wget git-core diffstat unzip texinfo gcc-multilib build-essential chrpath socat libsdl1.2-dev

$ sudo apt-get install -y libglu1-mesa-dev mercurial automake groff curl lzop asciidoc u-boot-tools mtd-utils

Deploy source

Download archive contains the build script and support files for building Debian (Jessie) for this board:

$ cd ~
$ git clone https://github.com/varigit/debian-var.git -b debian_jessie_varsommx6_var01 var_som_mx6_debian

Create environment (Internet connection should be available):

$ cd ~/var_som_mx6_debian
$ ./make_var_som_mx6_debian.sh -c deploy

This environment prepared to build.

Make Debian

Build all

Internet connection should be available

$ cd ~/var_som_mx6_debian
$ sudo ./make_var_som_mx6_debian.sh -c all | tee 2.log

Build by parts

Build bootloader

$ cd ~/var_som_mx6_debian
$ ./make_var_som_mx6_debian.sh -c bootloader

Build kernel, dtb files and kernel modules

$ cd ~/var_som_mx6_debian
$ ./make_var_som_mx6_debian.sh -c kernel
$ ./make_var_som_mx6_debian.sh -c modules

Build rootfs

Internet connection should be available

$ cd ~/var_som_mx6_debian
$ sudo ./make_var_som_mx6_debian.sh -c rootfs

Pack rootfs

For the create archive root file system (rootfs.tar.bz2) run the following commands:

$ cd ~/var_som_mx6_debian
$ sudo ./make_var_som_mx6_debian.sh -c rtar

Create boot SD card

Follow the steps for make rootfs, kernel, bootloader;
Insert the SD card to card reader connected to a host system;
Run the following commands (Caution! All data on the card will be destroyed):

$ cd ~/var_som_mx6_debian
$ sudo ./make_var_som_mx6_debian.sh -c sdcard -d /dev/sdX

where '/dev/sdX' path to the block SD device in your system.
