Building the meta-cedartrail BSP layer -II. Booting the images in /binary - - -I. Building the meta-cedartrail BSP layer -========================================= - -In order to build an image with BSP support for a given release, you -need to download the corresponding BSP tarball from the 'Board Support -Package (BSP) Downloads' page of the Yocto Project website. - -Having done that, and assuming you extracted the BSP tarball contents -at the top-level of your yocto build tree, you can build a cedartrail -image by adding the location of the meta-cedartrail layer to -bblayers.conf, along with the meta-intel layer itself (to access -common metadata shared between BSPs) e.g.: - - yocto/meta-intel \ - yocto/meta-intel/meta-cedartrail \ - -To enable the cedartrail layer that supports Power VR graphics, -add the cedartrail MACHINE to local.conf: - - MACHINE ?= "cedartrail" - -Power VR Graphics user-space driver binaries are covered by a -"Intel Free Distribution Binary License". The build of this driver -can be enabled by adding the following line to the local.conf file: - -LICENSE_FLAGS_WHITELIST += "license_cdv-pvr-driver_1.0.3" - -To enable the layer that does not support Power VR graphics -add the following to the local.conf file: - - MACHINE ?= "cedartrail-nopvr" - - -You should then be able to build a cedartrail image as such: - - $ source oe-init-build-env - $ bitbake core-image-sato - -The above image will not give you the webkit feature and will not -have the Audio and Video media samples in the image. - -If you want the webkit feature and Audio , Video media samples built -into the image by default, You should build the custom image by -doing the following: - - $ source oe-init-build-env - $ bitbake core-image-cdv-media - -At the end of a successful build, you should have a live image that -you can boot from a USB flash drive (see instructions on how to do -that below, in the section 'Booting the images from /binary'). - -NOTE: The 'cedartrail' machine will include support for hardware video -acceleration via gstreamer if and only if the "commercial" string is -added to the the LICENSE_FLAGS_WHITELIST variable in your local.conf. - -For example: - - LICENSE_FLAGS_WHITELIST = "license_cdv-pvr-driver_1.0.3 commercial" - -The reason this is needed is to prevent the image from including -anything that might violate the license terms of the packages used to -implement the the video acceleration feature, such as gst-ffmpeg and -ffmpeg. As always, please consult the licenses included in the -specific packages for details if you use packages that require -particular LICENSE_FLAGS. - -As an alternative to downloading the BSP tarball, you can also work -directly from the meta-intel git repository. For each BSP in the -'meta-intel' repository, there are multiple branches, one -corresponding to each major release starting with 'laverne' (0.90), in -addition to the latest code which tracks the current master. Instead -of extracting a BSP tarball at the top level of your yocto build tree, -you can equivalently check out the appropriate branch from the -meta-intel repository at the same location. - - -II. Booting the images in /binary -================================== - -This BSP contains bootable live images, which can be used to directly -boot Yocto off of a USB flash drive. - -Under Linux, insert a USB flash drive. Assuming the USB flash drive -takes device /dev/sdf, use dd to copy the live image to it. For -example: - -# dd if=core-image-sato-cedartrail-20120105232035.hddimg of=/dev/sdf -# sync -# eject /dev/sdf - -This should give you a bootable USB flash device. Insert the device -into a bootable USB socket on the target, and power on. This should -result in a system booted to the Sato graphical desktop. - -If you want a terminal, use the arrows at the top of the UI to move to -different pages of available applications, one of which is named -'Terminal'. Clicking that should give you a root terminal. - -If you want to ssh into the system, you can use the root terminal to -ifconfig the IP address and use that to ssh in. The root password is -empty, so to log in type 'root' for the user name and hit 'Enter' at -the Password prompt: and you should be in. - ----- - -If you find you're getting corrupt images on the USB (it doesn't show -the syslinux boot: prompt, or the boot: prompt contains strange -characters), try doing this first: - -# dd if=/dev/zero of=/dev/sdf bs=1M count=512 - -Miscellaneous Notes -==================== - -Video and Music Samples ------------------------ -This BSP includes recipes to download Ogg format video and -music files that can be played-back with the Video and music players -included in the sato images. The sample files are installed in -/home/Music and /home/Videos directories. - - -Adding Glxgears to image -------------------------- -Glxgears can be added to the generated image by adding "tools-testapps" -option to the extra image features variable in the default local.conf -before building the BSP. - -e.g. to add Glxgears, locate the following line in local.conf -EXTRA_IMAGE_FEATURES = "debug-tweaks" - -and change above line to.. - -EXTRA_IMAGE_FEATURES = "debug-tweaks tools-testapps" |
