MACHINE = "raspberrypi3"you can use raspberrypi2 as well if you own raspberrypi2 machine.
Ignore QT
BBMASK = "recipes-qt"Use 4.9 kernel
PREFERRED_VERSION_linux-raspberrypi = "4.9%"Build WPE with Westeros Compositor
bitbake wpe-westeros-imageFor 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/sdXwhere 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
mkdir -p /var/run/user/`id -u`/
chmod 0700 /var/run/user/`id -u`/
export XDG_RUNTIME_DIR=/var/run/user/`id -u`/
westeros --enableCursor --renderer libwesteros_render_dispmanx.so.0.0.0 --framerate 60 --display wayland-0&
export XDG_RUNTIME_DIR=/var/run/user/`id -u`/
export WAYLAND_DISPLAY=wayland-0
/usr/bin/WPELauncherThis 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&resumewhich 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 ! autoaudiosinkResize 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
