This README file contains information on building the meta-chiefriver BSP layer, and booting the images contained in the /binary directory. Please see the corresponding sections below for details.
The 'Chief River' platform consists of the Intel Ivy Bridge processor, plus the Panther Point PCH. This BSP assumes that the Ivy Bridge integrated graphics are being used.
Further information on the platforms supported by this BSP can be found here:

Information on all Intel® embedded platforms can be found here:

Compliance
This BSP is compliant with the Yocto Project as per the requirements listed here:

I. Building the meta-chiefriver 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 chiefriver image by adding the location of the meta-chiefriver 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-chiefriver \
To enable the chiefriver layer, add the chiefriver MACHINE to local.conf:
MACHINE ?= "chiefriver"
You should then be able to build a chiefriver image as such:
$ source oe-init-build-env $ bitbake core-image-sato
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 'chiefriver' 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 = "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 (note that not all BSPs are present in every release). 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-chiefriver-20101207053738.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:
