This README file contains information on building the meta-crownbay
BSP layer, and booting the images contained in the /binary directory.
Please see the corresponding sections below for details.

I. Building the meta-crownbay BSP layer
=======================================
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.
In order to build an image with BSP support for a given release, you
need to check out the 'meta-intel' branch corresponding to the release
you're building against e.g. to build for laverne (0.90), check out
the 'laverne' branch of both poky and 'meta-intel'.
Having done that, and assuming you cloned the 'meta-intel' repository
at the top-level of your yocto build tree, you can build a crownbay
image by adding the location of the meta-crownbay layer to
bblayers.conf e.g.:
yocto/meta-intel/meta-crownbay \
To enable the crownbay layer, add the crownbay MACHINE to local.conf:
MACHINE ?= "crownbay"
You should then be able to build a crownbay image as such:
$ source poky-init-build-env
$ bitbake poky-image-sato-live
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').
II. Special notes for building the meta-crownbay BSP layer
==========================================================
The meta-crownbay layer makes use of the proprietary Intel EMGD
userspace drivers, which at this point in time require that the user
accept the Intel license by manually extracting the binaries and
copying them to the proper location in the meta-crownbay layer.
There currently isn't an automated way to do this, thus the manual
step. When Yocto supports a click-through installation mechanism, the
binary files will be packaged as part of the recipe, and this step
will be unnecessary.
These steps require that you run a graphical application in Windows.
Windows 7 was used for these instructions, but it shouldn't matter
which version of Windows you use.
The first step of the process is to download the EMGD 1.5 Gold Driver.
Here is the current link to the URL which it can be downloaded from:
http://edc.intel.com/Software/Downloads/EMGD/
In the Download Now tab, select:
Intel® architecture-based product: Intel Atom Processor E6XX Series
Operating System: MeeGo 1.0 IVI Linux (kernel 2.6.33.3, X.server 1.8.0)
That will give you a large zip file:
IEMGD_1_5_GOLD_ALL_1742.zip
Extract the files in the zip file, which will in turn give you a large
.exe file:
IEMGD_1_5_GOLD_ALL_1742.exe
Run IEMGD_1_5_GOLD_ALL_1742.exe to install, accept licenses, etc.
If it says to install watcom, follow the instructions to do that.
When the installation completes, an application named "emgd-ced" will
be present in the install directory. Double-click to run it.
Select the menu item: New Configuration
In the tabbed page, make the following selections and/or enter the
specified data:
Configuration File Name: myconfig
Platform Chipset: Intel Atom Processor E6xx
Port Devices: LVDS, sDVO
Hit the 'Next' button.
On the next tabbed page, make the following selections and/or enter
the specified data:
Readable Port Name: portname0
Encoder Configuration: Select sDVO Device: Internal LVDS
Hit the 'Finish' button.
Select the menu item: New Package
In the tabbed page, make the following selections and/or enter the
specified data:
Package File Name: mypackage
Configurations: selec myconfig.cnfg
Target OS: Linux operating System
Hit the 'Finish' button.
Select the menu item: Generate Installation
This will create the EMGD installation package:
Generating EMGD installation...
The installation package should now be under the 'workspace'
subdirectory of the directory you installed to:
workspace/installation/mypackage.pkg_installation/IEMGD_HEAD_Linux/IEMGD_HEAD_Linux.tgz
This is the file you are interested in. Copy it to your Poky build
system, and uncompress/untar it:
$ tar cvfz IEMGD_HEAD_Linux.tgz
Finally, copy Xorg-xserver binaries in the Meego1.0 driver directory
to the xserver-xf86-emgd-bin directory in the meta-crownbay layer:
$ cp IEMGD_HEAD_Linux/MeeGo1.0/driver/Xorg-xserver-1.7.99/* meta-crownbay/recipes-graphics/xorg-xserver/xserver-xf86-emgd-bin
You also need to copy the IEMGD License.txt file to the same directory:
$ cp IEMGD_HEAD_Linux/License/License.txt meta-crownbay/recipes/xorg-xserver/xserver-xf86-emgd-bin
At this point, you should be able to build meta-crownbay images as usual.

For reference, the EMGD Driver documentation is also available at the
above link (it's also part of the installation).
The specific text of the document is:
User Guide: Intel® Embedded Media and Graphics Driver, EFI Video
Driver, EPOG, and Video BIOS v1.5 for Windows* XP and Linux* Provides
installation requirements/procedures & describes the vbios/firmware,
configuration options, & functionality of Intel® EMGD under Windows* &
Linux*. Refer to guide for details.

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=poky-image-sato-live-crownbay-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:
# dd if=/dev/zero of=/dev/sdf bs=1M count=512
