This Wiki section guides through preparation and compiling images using Yocto Project.
Download and install repo utility
Note: As Freescale disabled its primary git servers, the official repositories were moved. The files for building can be accessed by following this workaround.
To download the board support package, repositories need to be installed. To prepare them follow these steps:
mkdir -pv ~/workdir/bin
# curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/workdir/bin/repo
chmod a+x ~/workdir/bin/repo
PATH=${PATH}:~/workdir/bin
Yocto Project 2.1
Every OS requires different set of installed packages. More information about Yocto requirements could be acquired in Freescale Yocto Project User's Guide.
Initialize Yocto Project
Download the BSP Yocto Project Environment:
mkdir -pv ~/workdir/voipac/imx6/yocto/fsl-release-bsp-2.1 cd ~/workdir/voipac/imx6/yocto/fsl-release-bsp-2.1 git config --global user.name "Your Name" git config --global user.email "Your Email" git config --list repo init -u git://git.freescale.com/imx/fsl-arm-yocto-bsp.git -b imx-4.1-krogoth
Init iMX6 Rex layer
Add iMX6 Rex support:
mkdir -pv .repo/local_manifests/
cat > .repo/local_manifests/imx6rex.xml << EOF
<?xml version="1.0" encoding="UTF-8"?>
<manifest>
<remote fetch="git://github.com/Voipac" name="voipac"/>
<project remote="voipac" revision="master" name="meta-fsl-arm-voipac" path="sources/meta-fsl-arm-voipac">
<copyfile src="voipac-setup.sh" dest="voipac-setup.sh"/>
</project>
</manifest>
EOF
Sync
Synchronize repositories:
cd ~/workdir/voipac/imx6/yocto/
ln -s fsl-release-bsp-2.1 fsl-release-bsp
cd ~/workdir/voipac/imx6/yocto/fsl-release-bsp
PATH=${PATH}:~/workdir/bin
repo sync
Configure
Add Voipac meta layer into BSP:
source voipac-setup.sh
Build workarounds
Building process could get halted. This session contains few workarounds for commonly observed failures. These commands fix compiling on Ubuntu 16.04 operating system.
Issue: Preferred bootloader and kernel are overwritten during compilation fsl-image recipe
Cause and fix: fsl-image overwrite bootloader/kernel provided by meta-fsp-voipac. To remove this limitation replace '=' with '?='

Build customization
Configuration files are created during setup (setup-environment, fsl-setup-release.sh). The file to update can be found:
/workdir/voipac/imx6/yocto/fsl-release-bsp/build-x11/conf/local.conf
By modifying local.conf file, custom features can be easily added:
#CORE_IMAGE_EXTRA_INSTALL += " chromium libexif"
CORE_IMAGE_EXTRA_INSTALL += " firefox stress"
LICENSE_FLAGS_WHITELIST = "commercial"
IMAGE_INSTALL_append = " \
video-input-demo \
multimedia-demo \
lpc-demo \
"
IMAGE_ROOTFS_EXTRA_SPACE_append += "+ 500000"
Working environment setup has been finished and is ready for building images.

Yocto Project 1.7
Every OS requires different set of installed packages. More information about Yocto requirements could be acquired in Freescale Yocto Project User's Guide.

source voipac-setup.sh
Build workarounds
Building process could get halted. This session contains few workarounds for commonly observed failures. These commands fix compiling on Ubuntu 16.04 operating system.
Issue: GCC compilator downgrade
Cause and fix: Ubuntu uses GCC-5 by default but some Yocto (branch imx-3.14.28-1.0.1_patch) packages are not compatible with this compiler. To keep the functionality, switching to older version is required:
sudo apt-get install gcc-4.8 g++-4.8 sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.8 100 --slave /usr/bin/g++ g++ /usr/bin/g++-4.8 sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-5 50 --slave /usr/bin/g++ g++ /usr/bin/g++-5 sudo update-alternatives --config gcc
Issue: Qemu-native compilation failure
Cause and fix: Ubuntu uses newer version of the SDL libraries which are not compatible with Yocto (branch imx-3.14.28-1.0.1_patch).
This commands needs to be run after every "source *" command to commend out SDL support:
sed -i 's/^PACKAGECONFIG_append_pn-qemu-native/#PACKAGECONFIG_append_pn-qemu-native/' conf/local.conf sed -i 's/^PACKAGECONFIG_append_pn-nativesdk-qemu/#PACKAGECONFIG_append_pn-nativesdk-qemu/' conf/local.conf
Build customization
Configuration files are created during setup (setup-environment, fsl-setup-release.sh). The file to update can be found:
/workdir/voipac/imx6/yocto/fsl-release-bsp/build-x11/conf/local.conf
By modifying local.conf file, custom features can be easily added:
CORE_IMAGE_EXTRA_INSTALL += " chromium"
CORE_IMAGE_EXTRA_INSTALL += " packagegroup-fslc-gstreamer1.0-full"
LICENSE_FLAGS_WHITELIST = "commercial"
IMAGE_INSTALL_append = " \
