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 16.04 image from Docker Hub 

$ docker pull advrisc/u16.04-imx8lbv1

$ docker run --name imx6LBV90006 -it advrisc/u16.04-imx8lbv1 /bin/bash

To copy BSP from local filesystem to the container

$ docker cp ${BSP_PACK} imx6LBV90006:/home/adv/ 

To create container

$ docker run --privileged -it --name ${CONTAINER_NAME} -v ${WORKSPACE}:/home/adv/adv-release-bsp -v /dev:/dev advrisc/u16.04-imx8lbv1 /bin/bash

Get BSP

You have two methods to put BSP into container created above

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 "imx6LBV90006" is taken as an example :

TBD

If you want to get latest bsp

$ repo init -u git://github.com/ADVANTECH-Corp/adv-arm-yocto-bsp.git  -b imx-linux-sumo -m imx-4.14.98-2.0.0_ga.xml 
$ repo sync

Copy BSP tarball to Container

TBD

Downloads tarball

TBD

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, BSP file name: imx6LBV90006_2019-07-06.tgz

which , "LB" is acronym of Linux BSP,

           "V90006" stands for Version 9.0006

For example, Yocto image name: 7421A1LIV90006_DualPlus_2019-07-06.img.gz

which "7421A1" stands for ROM-7421 A1

          "LI" is acronym for prebuilt Linux Image,

          "DualPlus" means this image is fit for Dual Plus Core/Quad Plus Core.

For example, Yocto image name: 3420A1LIV90008_DualQuad_2019-07-08.img.gz

which "3420A1" stands for ROM-3420 A1

          "LI" is acronym for prebuilt Linux Image,

          "DualQuad" means this image is fit for Dual Core/Quad Core.

For example, Yocto image name: U220A1LIV90009_DualLiteSolo_2019-07-09.img.gz

which "U220A1" stands for UBC-220 A1

          "LI" is acronym for prebuilt Linux Image,

          "DualLiteSolo" means this image is fit for Dual Lite Core/Solo Core.

Build Instructions

To create one new build environment

Perform the following commands in terminal console

$ cd ${BSP_HOME}

$ MACHINE=${MC} DISTRO=fsl-imx-wayland source fsl-setup-release.sh -b ${BDIR}

You need to read and accept the EULA.

To continue an exist build environment

Perform the following commands in terminal console

$ cd ${BSP_HOME}
