=== <span style="color:#0070c0">Copy BSP tarball to Container</span> ===
 +
 +
:If you have BSP tarball (eg. imx8LBV90029_2019-10-23.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 ${WORKSPACE} , and change owner
 +
 +
$ cp imx8LBV90029_2019-10-23.tgz '''${WORKSPACE}'''
 +
$ sudo chown adv:adv ${WORKSPACE}/imx8LBV90029_2019-10-23.tgz&nbsp;
 +
 +
3.Back to container
 +
 +
$ docker start '''${CONTAINER_NAME}'''
 +
$ docker attach '''${CONTAINER_NAME}'''
 +
 +
4.Unpack BSP tarball
 +
 +

== <span style="color:#0070c0">Introducing BSP</span> ==
 +
 +
:The BSP is based on Yocto Project with Freescale enhanced features for i.MX8, 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.

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 18.04 image from Docker Hub 

$ docker pull advrisc/u18.04-imx8lbv1

To create container

$ docker run --privileged -it --name ${CONTAINER_NAME} -v ${WORKSPACE}:/home/adv/adv-release-bsp -v /dev:/dev advrisc/u18.04-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/iMX8/OS_Support_List , Official version "imx8LBV90029" is taken as an example :
$ git config --global user.name "Your Name"
$ git config --global user.email you@example.com
$ sudo chown adv:adv adv-release-bsp
$ cd adv-release-bsp
$ repo init -u git://github.com/ADVANTECH-Corp/adv-arm-yocto-bsp.git -b refs/tags/imx8LBV90029 -m imx8LBV90029.xml 
$ repo sync
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
If you suffer "server certificate verification failed", you can use the following command to disable SSL verification in git repositories with self-signed certificates.
$ export GIT_SSL_NO_VERIFY=1

or

$ git config --global http.sslverify false

 

''''''The unauthenticated git protocol on port 9418 is no longer supported''''''

To Solve The unauthenticated git protocol on port 9418 is no longer supported Error This error May occurs due to latest '''Improving Git protocol security on GitHub '''which was released on '''January 11, 2022 Final brownout.''' Simple solution is Before You Install Just Set url to globally to set url globally Run this command:''' git config –global url.”[https://”.insteadOf https://”.insteadOf] git://''' Now, Your error must be solved.

Copy BSP tarball to Container

If you have BSP tarball (eg. imx8LBV90029_2019-10-23.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 ${WORKSPACE} , and change owner

$ cp imx8LBV90029_2019-10-23.tgz ${WORKSPACE}
$ sudo chown adv:adv ${WORKSPACE}/imx8LBV90029_2019-10-23.tgz 

3.Back to container

$ docker start ${CONTAINER_NAME}
$ docker attach ${CONTAINER_NAME}

4.Unpack BSP tarball

$ tar zxvf imx8LBV90029_2019-10-23.tgz

Downloads tarball

Not necessarily step
During building  Yocto image , it will generate downloads folder which includes all packages we need , but it usually can't fetch normally, so we keep this downloads folder. Then we can reduce some fetch failed issue.
You can get Downloads tarball (downloads_imx8-2.5.tgz) from following URL:
[downloads_imx8-2.5.tgz], md5 checksum: 4971ce00d3d0cdc48a5f35b584920c07
If you get downloads tarball, you can copy to your ${WORKSPACE}

Follow the steps below:

1.Exit container and back to local machine

$ exit

2.Copy Downloads tarball to ${WORKSPACE} , and change owner

$ cp downloads_imx8-2.5.tgz ${WORKSPACE}
$ sudo chown adv:adv ${WORKSPACE}/downloads_imx8-2.5.tgz 

3.Back to container

$ docker start ${CONTAINER_NAME}
$ docker attach ${CONTAINER_NAME}

4.Unpack Downloads tarball

$ tar zxvf downloads_imx8-2.5.tgz

5.make link to downloads folder

$ cd adv-release-bsp
$ ln -s ${WORKSPACE}/downloads_imx8-2.5 downloads

Introducing BSP

The BSP is based on Yocto Project with Freescale enhanced features for i.MX8, 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: imx8LBV90010_2019-08-27.tgz
which , "LB" is acronym of Linux BSP,
           "V90010" stands for Version 9.0010 .


 

 

 

 

 

 

 

 

 

 

For example, Yocto image name: '5720A1AIM20LIV90010_iMX8M_2019-08-27.img.gz'
which "5720A1" stands for ROM-5720 A1
          "LI" is acronym for prebuilt Linux Image

How to get the MAC, Serial Number, and Manufacture Date in the QSPI flash

MAC 0:

READ_DATA=`dd if=/dev/mtdblock0 bs=1 skip=$((0xd0000)) count=6 2> /dev/null | hexdump -e '16/1 "%02x " "\n"' | sed 's/ /:/g' | cut -c 1-17`
echo $READ_DATA

MAC 1:

READ_DATA=`dd if=/dev/mtdblock0 bs=1 skip=$((0xd0400)) count=6 2> /dev/null | hexdump -e '16/1 "%02x " "\n"' | sed 's/ /:/g' | cut -c 1-17`
echo $READ_DATA

Serial Number:

READ_DATA=`dd if=/dev/mtdblock0 bs=1 skip=$((0xd0006)) count=10 2> /dev/null | cut -c 1-10`
