Docker install and setting

If you don't have docker in your system, then you can follow the below  steps to install docker and run it first.

To install Docker Engine on your platform

Please refer to Docker Installation Guide for details

To pull ubuntu 12.04 image from Docker Hub 

$ docker pull advrisc/u12.04-imx6lbv3

To create container

$ docker run --privileged --name imx6LBV8010 -it -v ${SD_DEVICE}:${SD_DEVICE} advrisc/u12.04-imx6lbv3 /bin/bash

Get BSP

You have two methods to put BSP into container created above

Method 1:Download BSP From GitHub

The following example shows how to download the Advantech Yocto BSP from GitHub.

For this example, a directory called adv-release-bsp is created for the project.

Refer to IoTGateway/BSP/Linux/iMX6/OS Support List new , Official version "imx6LBV8010" is taken as an example :
$ mkdir adv-release-bsp
$ cd adv-release-bsp
$ repo init -u git://github.com/ADVANTECH-Corp/adv-arm-yocto-bsp.git -b imx-4.1-krogoth -m imx6LBV8010.xml
$ repo sync

Method 2:Copy BSP tarball to Container

If you have BSP tarball (eg. imx6LBV8010_2016-12-28.tgz), then you have to copy it into container.

Follow the steps below:

1.Exit container and back to local machine

$ exit

2.Copy BSP tarball to container

$ docker cp imx6LBV8010_2016-12-28.tgz imx6LBV8010:/home/adv

3.Back to container

$ docker start imx6LBV8010
$ docker attach imx6LBV8010

4.Unpack BSP tarball

$ tar zxvf imx6LBV8010_2016-12-28.tgz

Introducing BSP

The BSP is based on Yocto Project with Freescale enhanced features for i.MX6, plus specific target board features from Advantech Inc..
The Advantech Yocto Project BSP Release directory contains a "sources" directory, which contains the recipes used to build,

one or more build directories, and a set of scripts used to set up the environment.

The recipes used to build the project come from both the community and Advantech. The Yocto Project layers are downloaded

to the sources directory. This sets up the recipes that are used to build the project.

Naming Rule

The tarball/prebuilt image name is consist of the model name followed by "LB" or "LI" plus version number and released date.
For example, imx6LBV8010_2016-12-28.tgz
which , "LB" is acronym of Linux BSP,
           "V8010" stands for Version 8.010.
For example, 3420A1LIV8010_DualQuad_2016-12-28.img.gz
which "3420A1" stands for ROM-3420 A1
          "LI" is acronym for prebuilt Linux Image,</span>
          "DualQuad" means this image is fit for Dual Core/Quad Core.</span>

Start building kernel modules
$ make -j4 modules LDFLAGS=
Copy all modules to a temporary rootfs directory, "~/temp/rootfs"
$ make modules_install INSTALL_MOD_PATH=~/temp/rootfs
Start building device tree blob
$ make -j4 ${IMX6PROC}-${BOARD}-${BOARD_REV}.dtb
The device tree blob, ${IMX6PROC}-${BOARD}-${BOARD_REV}.dtb, is located in the directory "./arch/arm/boot/dts/".

To update kernel/modules/dtb to target device

Copy zImage & ${IMX6PROC}-${BOARD}-${BOARD_REV}.dtb to the 1st partition of SD card
Copy modues to the 2nd partition of SD card.
Make sure all new linux kernel, device tree and kernel modules work well, then copy all of them to the on-board flash
