:For this example, a directory called '''adv-release-bsp''' is created for the project.
 
 
 
:Refer to&nbsp;[[IoTGateway/BSP/Linux/iMX7/OS_Support_List_new|IoTGateway/BSP/Linux/iMX7/OS Support List new]] , Official version "'''imx6LBV8xxx"&nbsp;'''is taken as&nbsp;an example&nbsp;:

=== <span style="color:#0070c0">Copy BSP tarball to Container</span> ===
 
 
 
:If you have BSP tarball (eg. imx6LBV8xxx_2018-xx-xx.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 imx6LBV8xxx_2018-xx-xx.tgz '''${WORKSPACE}'''
 
$ sudo chown adv:adv ${WORKSPACE}/imx6LBV8xxx_2018-xx-xx.tgz&nbsp;
 
 
 
3.Back to container
 
 
 
$ docker start '''${CONTAINER_NAME}'''
 
$ docker attach '''${CONTAINER_NAME}'''
 
 
 
4.Unpack BSP tarball
 
 
 
$ tar zxvf imx6LBV8xxx_2018-xx-xx.tgz
 
 
 
== <span style="color:#0070c0">Downloads tarball</span> ==
 
 
 
:Not necessarily step
 
 
 
:During building &nbsp;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-2.1.tar.gz) from following URL:
 
 
 
:<code>[https://pan.baidu.com/s/1nvqgx2T#list/path=/ELAA/imx6_yocto_bsp_2.1_2.0.0/downloads&parentPath=/ELAA https://pan.baidu.com/s/1nvqgx2T#list/path=%2FELAA%2Fimx6_yocto_bsp_2.1_2.0.0%2Fdownloads&parentPath=%2FELAA]</code>
 
 
 
: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-2.1.tar.gz '''${WORKSPACE}'''
 
$ sudo chown adv:adv ${WORKSPACE}/downloads-2.1.tar.gz&nbsp;
 
 
 
3.Back to container
 
 
 
$ docker start '''${CONTAINER_NAME}'''

== <span style="color:#0070c0">Introducing BSP</span> ==
 
 
 
: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.
 
 
 
=== <span style="color:#0070c0">Naming Rule</span> ===
 
 
 
: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: imx6LBV8040_2017-01-16.tgz'''<br/>
 
:which , "LB" is acronym of <span style="color:#ff0000">'''L'''</span>inux <span style="color:#ff0000">'''B'''</span>SP,<br/>
 
:&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;"V8040" stands for <span style="color:#ff0000">'''V'''</span>ersion <font color="#ff0000">'''8'''</font>.<span style="color:#ff0000">'''040'''</span><nowiki>.</nowiki>
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
:For example, '''Yocto image name: 7421A1LIV8040_DualPlus_2017-01-16.img.gz'''<br/>
 
:which "7421A1" stands for <span style="color:#ff0000">'''ROM-7421 A1'''</span><br/>
 
:&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "LI" is acronym for prebuilt <span style="color:#ff0000">'''L'''</span>inux <span style="color:#ff0000">'''I'''</span>mage,<br/>
 
:&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "DualPlus" means this image is fit for Dual Plus Core/Quad Plus Core.
 
 
 
:For example, '''Yocto image name: 3420A1LIV8050_DualQuad_2017-01-17.img.gz'''<br/>
 
:which "3420A1" stands for <span style="color:#ff0000">'''ROM-3420 A1'''</span><br/>
 
:&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "LI" is acronym for prebuilt <span style="color:#ff0000">'''L'''</span>inux <span style="color:#ff0000">'''I'''</span>mage,<br/>
 
:&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "DualQuad" means this image is fit for Dual Core/Quad Core.
 
 
 
:For example, '''Yocto image name: U220A1LIV8080_DualLiteSolo_2017-02-08.img.gz'''<br/>
 
:which "U220A1" stands for <span style="color:#ff0000">'''UBC-220 A1'''</span><br/>
 
:&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "LI" is acronym for prebuilt <span style="color:#ff0000">'''L'''</span>inux <span style="color:#ff0000">'''I'''</span>mage,<br/>
 
:&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "DualLiteSolo" means this image is fit for Dual Lite Core/Solo Core.

*Bootloader
 
 
 
1.bootdelay time
 
 
 
:We can cancel the bootdelay time by setting bootloader environment value.
 
 
 
setenv bootdelay 0
 
env save
 
reset
 
 
 
2.Disable console
 
 
 
:Disable debug message output can also improve boot speed
 
 
 
Disable kernel message
 
 
 
setenv mmcargs setenv bootargs console=${console},${baudrate} ${smp} root=${mmcroot} ${bootargs} '''quiet'''
 
env save
 
reset
 
 
 
Or
 
 
 
:Disable debug port
 
 
 
setenv console
 
env save
 
reset
 
 
 
*Rootfs
 
 
 
1.Use smaller rootfs
 
 
 
:We can speed up boot times by using a smaller rootfs instead of fsl-image-qt5 image
 
 
 
eg. core-image-full-cmdline, core-image-minimal
 
 
 
bitbake core-image-full-cmdline
 
 
 
It's a console-only image with more full-featured Linux system functionality installed.
 
 
 
And replace the original fsl-image-qt5 rootfs.
 
 
 
*Services
 
 
 
1. Using '''update-rc.d''' remove ,we can remove unnecessary services.
 
 
 
update-rc.d -f <basename> remove
 
 
 
= System Recovery =
 
 
 
Please refer to [[#Creating_boot-up_on-board_flash_from_prebuilt_image|Creating boot-up on-board flash from prebuilt image]] / [[#Creating_boot-up_on-board_flash_from_built_sdcard_image|sdcard image]] to create a boot-up SD card and transfer whole system to on-board flash.
 
 
 
= Package List =
 
 
 
'''In BSP''', list all packages which will be built in the image
 
 
 
bitbake -g '''fsl-image-qt5''' && cat pn-depends.dot | grep -v -e '-native' | grep -v digraph | grep -v -e '-image' \
