Please read the Yocto tutorial before you proceed. The following instruction were tested on our DHCOM i.MX6 computer on module with Yocto stable branch Dizzy.

The following steps provide a step by step guide to build a image with

  • Chromium: The open-source web browser from Google with HTML5 and WebGL support.
  • VLC Media Player: The famouse portable, free and open-source media player and streaming media server provided by the VideoLAN project.
  • X11VNC: Enables to view remotely and to interact (mouse, keyboard) with X displays.

Configure Sources

Clone meta-browser

Clone the branch master of meta-browser inside the yocto/sources directory: 

$ git clone -b master https://github.com/OSSystems/meta-browser.git

Note: Verified with chromium sources version 38.0.2125.101

Edit your yocto configuration files

1. Edit yocto/build/conf/bblayers.conf to add the meta-browser layer at the end: 

 ${BSPDIR}/sources/meta-browser \

2. Verified example yocto/build/conf/local.conf: 

MACHINE ??= 'dhcomimx6dl'
DISTRO ?= 'poky'
PACKAGE_CLASSES ?= "package_ipk"
EXTRA_IMAGE_FEATURES = "debug-tweaks tools-debug ssh-server-openssh eclipse-debug"
USER_CLASSES ?= "buildstats image-mklibs image-prelink"
PATCHRESOLVE = "noop"
BB_DISKMON_DIRS = "\
    STOPTASKS,${TMPDIR},1G,100K \
    STOPTASKS,${DL_DIR},1G,100K \
    STOPTASKS,${SSTATE_DIR},1G,100K \
    ABORT,${TMPDIR},100M,1K \
    ABORT,${DL_DIR},100M,1K \
    ABORT,${SSTATE_DIR},100M,1K" 
PACKAGECONFIG_append_pn-qemu-native = " sdl"
PACKAGECONFIG_append_pn-nativesdk-qemu = " sdl"
ASSUME_PROVIDED += "libsdl-native"
CONF_VERSION = "1"
PREFERRED_PROVIDER_jpeg = "libjpeg-turbo"
PREFERRED_PROVIDER_shlib = "libjpeg-turbo"
PREFERRED_PROVIDER_jpeg-native = "libjpeg-turbo-native"
PREFERRED_PROVIDER_virtual/mesa = "mesa"
PREFERRED_PROVIDER_virtual/libgl = "gpu-viv-bin-mx6q"
PREFERRED_PROVIDER_mesa-driver-swrast = "mesa-gl"

BB_NUMBER_THREADS = '2'
PARALLEL_MAKE = '-j 2'

#DL_DIR ?= "${BSPDIR}/downloads/"
ACCEPT_FSL_EULA = ""

LICENSE_FLAGS_WHITELIST = " commercial_libav commercial_x264 commercial"

IMAGE_INSTALL_append = " \
	chromium \
	gst-plugins-base \
	gst-plugins-gl \
	gst-fsl-plugin \
	gstreamer1.0-plugins-imx \

	fsl-alsa-plugins \
	pulseaudio \
	libfslvpuwrap \
	libfslparser \
	mpeg2dec \
	vlc \
	x11vnc"

Bitbake!

Bitbake an image like core-image-x11(you need to be in your yocto/build directory): 

 $ MACHINE=dhcomimx6dl . ./setup-environment build
 $ bitbake core-image-x11

Note: Bitbake fails with an dependency error. To fix the build edit 'tmp/sysroots/dhcomimx6dl/usr/lib/libQtGui.la' and run bitbake again. 

-dependency_libs=' -lEGL -lGAL -DLINUX=1 -DEGL_API_FB=1 -lQtCore -lpthread '
+dependency_libs=' -lEGL -lGAL -lQtCore -lpthread '

Test your image

execute chromium: 

 $ google-crome

execute VLC media player: 

 $ vlc

start X11VNC (on default port 5900 is used): 

 $ x11vnc &

Note: Connection was verified with ssvnc (sudo apt-get install ssvnc) using SSH.
