Download and install repo utility

To get the BSP you need to have repo installed. To install it 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 are in Freescale Yocto Project User's Guide.

Initialise 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 Tinyrex layer

Add iMX6 TinyRex support: 

mkdir -pv .repo/local_manifests/
cat > .repo/local_manifests/imx6rex.xml << EOF
<?xml version="1.0" encoding="UTF-8"?>
<manifest>

  </project>
</manifest>
EOF

Sync

Synchronise 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 '?='

Original version: 

meta-fsl-bsp-release/imx/meta-sdk/conf/distro/include/fsl-imx-preferred-env.inc:PREFERRED_PROVIDER_u-boot_mx6 = "u-boot-imx"
meta-fsl-bsp-release/imx/meta-sdk/conf/distro/include/fsl-imx-preferred-env.inc:PREFERRED_PROVIDER_virtual/bootloader_mx6 = "u-boot-imx"
meta-fsl-bsp-release/imx/meta-sdk/conf/distro/include/fsl-imx-preferred-env.inc:PREFERRED_PROVIDER_virtual/kernel_mx6 = "linux-imx"

Modified version: 

meta-fsl-bsp-release/imx/meta-sdk/conf/distro/include/fsl-imx-preferred-env.inc:PREFERRED_PROVIDER_u-boot_mx6 ?= "u-boot-imx"
meta-fsl-bsp-release/imx/meta-sdk/conf/distro/include/fsl-imx-preferred-env.inc:PREFERRED_PROVIDER_virtual/bootloader_mx6 ?= "u-boot-imx"
meta-fsl-bsp-release/imx/meta-sdk/conf/distro/include/fsl-imx-preferred-env.inc:PREFERRED_PROVIDER_virtual/kernel_mx6 ?= "linux-imx"


Issue: Web browser recipes are disabled
Fix: Comment out to enable

meta-browser/recipes-browser/chromium/chromium_48.0.2548.0.bb:#PNBLACKLIST[chromium] ?= "BROKEN: fails to build with gcc-6"
meta-browser/recipes-browser/chromium/cef3_280796.bb:#PNBLACKLIST[cef3] ?= "BROKEN: fails to build with gcc-6"
meta-browser/recipes-mozilla/firefox/firefox_38.8.0esr.bb:#PNBLACKLIST[firefox] ?= "BROKEN: fails to build with gcc-6"

Build customisation

Configuration files are created during setup (setup-environment, fsl-setup-release.sh).
By modifying local.conf files we can easily add custom features. The file can he found 

/workdir/voipac/imx6/yocto/fsl-release-bsp/build-x11/conf/local.conf
#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"

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 aren't 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 --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:
