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.

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.

Flash images to eMMC
If you want to flash images on eMMC, on the device, as root, run the following command:
# debian-emmc.sh
The above command are located in /usr/bin folder of uSD card used to boot debian.
