Documentation for running RDK profiles ( Video, broadband, Camera ) on Raspberrypi boards

Setting up workspace

mkdir rpi-yocto
git clone git://git.yoctoproject.org/poky
git clone git://git.openembedded.org/meta-openembedded
git clone git://git.yoctoproject.org/meta-raspberrypi
git clone git://github.com/WebPlatformForEmbedded/meta-wpe
git clone git://github.com/96boards/meta-96boards

source poky/oe-init-build-env rpi-ml-build

bitbake-layers add-layer ../meta-openembedded/meta-oe
bitbake-layers add-layer ../meta-openembedded/meta-multimedia
bitbake-layers add-layer ../meta-openembedded/meta-python
bitbake-layers add-layer ../meta-openembedded/meta-networking

Edit conf/local.conf Set Machine

MACHINE = "raspberrypi3"

you can use raspberrypi2 as well if you own raspberrypi2 machine.

Ignore QT

BBMASK = "recipes-qt"

Remove X11 from distro features

DISTRO_FEATURES_remove_rpi = "x11"

Build WPE with Westeros Compositor

bitbake wpe-westeros-image

For westeros-wpe-image to runtime test. Here are steps, please document them publicly so folks using this image Can try them out. These are validated on RaspberryPI3

sudo dd if=tmp/deploy/images/raspberrypi3/westeros-wpe-image-raspberrypi3.rpi-sdimg of=/dev/sdX

where X is the letter a,b,c which your box would have mounted the uSD card on you can check that with dmesg | tail -10 when you insert the card into your computer.

Once booted login as ‘root’ it has no password

Run

export XDG_RUNTIME_DIR=/tmp
export WAYLAND_DISPLAY=wayland-0
/usr/bin/WPELauncher

This should result in WPE launched on screen and you can try to play a video manually

Or you can launch a video like

/usr/bin/WPELauncher https://www.youtube.com/tv#/watch/video/control?v=-YGDyPAwQz0&resume

which will play one video automatically

Second test is to run big bunny video launch it like

gst-launch-1.0 souphttpsrc location="http://download.blender.org/peach/bigbuckbunny_movies/big_buck_bunny_720p_h264.mov" ! typefind ! qtdemux name=demux demux. ! queue ! h264parse ! omxh264dec ! glimagesink demux. ! queue ! faad ! autoaudiosink

Resize SD-Card

Add in local.conf

CORE_IMAGE_EXTRA_INSTALL_append = " 96boards-tools "

and build the image again and flash it to SD-Card then run the following after firstboot.

parted /dev/mmcblk0 resizepart 2 100%
resize2fs -p /dev/mmcblk0p2
reboot

With systemd if dhcp does not work then you have to set /etc/resolv.conf symlink correctly.

ln -sf /run/systemd/resolve/resolv.conf /etc/resolv.conf

Cheap and reliable Node.js hosting starts at $3/month, and $1/month static HTML hosting
