How to create an image for Yocto Project 2.0

Follow instructions below to create an Yocto Projet Jethro image

Prerequisites

First we need to get the command repo

sudo aptitude install repo
sudo aptitude update
sudo aptitude upgrade

or by downloading it

mkdir bin
curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > bin/repo
chmod a+x bin/repo
PATH=${PATH}:bin

Then create our work directory

mkdir fsl-community-bsp && cd fsl-community-bsp

1) Get YOCTO project from Freescale

Download Yocto project using this command

repo init -u https://github.com/Freescale/fsl-community-bsp-platform -b jethro

2) Create the manifest file

Create manifest directory

mkdir -p .repo/local_manifests/

Create the manifest file

cat > .repo/local_manifests/imx6openrex.xml << EOF
<?xml version="1.0" encoding="UTF-8"?>
<manifest>
    <remote fetch="git://github.com/FEDEVEL" name="fedevel"/>
    <project remote="fedevel" revision="jethro" name="meta-openrex" path="sources/meta-openrex">
        <copyfile src="openrex-setup.sh" dest="openrex-setup.sh"/>
	</project>
</manifest>
EOF

3) Download all repositories needed

repo sync

4) Add OpenRex meta layer

source openrex-setup.sh

5) Setup and build console image

MACHINE=imx6s-openrex source setup-environment build-openrex
MACHINE=imx6s-openrex bitbake core-image-base

6) Mount to the SD card

umount /dev/YourSDCard
gunzip -c build-openrex/tmp/deploy/images/imx6s-openrex/core-image-base-imx6s-openrex.sdcard.gz > build-openrex/tmp/deploy/images/imx6s-openrex/core-image-base-imx6s-openrex.sdcard
sudo dd if=build-openrex/tmp/deploy/images/imx6s-openrex/core-image-base-imx6q-openrex.sdcard of=/dev/YourSDCard
umount /dev/YourSDCard

How to create an image for Yocto Project 2.1

Follow the instruction below to create an Yocto Projet Krogoth image

Prerequisites

First we need to get the command repo with package

sudo aptitude install repo
sudo aptitude update
sudo aptitude upgrade

or by downloading it

mkdir bin
curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > bin/repo
chmod a+x bin/repo
PATH=${PATH}:bin

Then create our work directory

mkdir fsl-community-bsp && cd fsl-community-bsp

1) Get YOCTO project from Freescale

Download Yocto project using this command

repo init -u git://git.freescale.com/imx/fsl-arm-yocto-bsp.git -b imx-4.1-krogoth

2) Create the manifest file

Create manifest directory

mkdir -p .repo/local_manifests/

Create the manifest file

cat > .repo/local_manifests/imx6rex.xml << EOF
<?xml version="1.0" encoding="UTF-8"?>
<manifest>
    <remote fetch="git://github.com/Voipac" name="voipac"/>
    <project remote="voipac" revision="master" name="meta-fsl-arm-voipac" path="sources/meta-fsl-arm-voipac">
        <copyfile src="voipac-setup.sh" dest="voipac-setup.sh"/>
    </project>
</manifest>
EOF

3) Download all repositories needed

repo sync

4) Add OpenRex meta layer

source voipac-setup.sh

5) Setup and build console image

MACHINE=imx6-openrexbasic source setup-environment build-dir
MACHINE=imx6-openrexbasic bitbake core-image-base

6) Mount to the SD card

umount /dev/YourSDCard
gunzip -c build-dir/tmp/deploy/images/imx6-openrexbasic/core-image-base-imx6-openrexbasic.sdcard.gz > build-openrex/tmp/deploy/images/imx6-openrexbasic/core-image-base-imx6-openrexbasic.sdcard
sudo dd if=build-openrex/tmp/deploy/images/imx6-openrexbasic/core-image-base-imx6-openrexbasic.sdcard of=/dev/YourSDCard
umount /dev/YourSDCard

7) Set Bootmmc

You will get an error like : Error "bootmmc" not defined, to fix this issue use the command below

setenv bootmmc "run findfdt; mmc dev ${mmcdev}; if mmc rescan; then if run loadbootscript; then run bootscript; else if run loadimage; then run mmcboot; else run netboot; fi; fi; else run netboot; fi;\0"; saveenv; reset;

Boot the OpenRex

Now plug your SD card in the OpenRex and it will boot on your Yocto image.
