1This README file contains information on building the meta-crystalforest
2BSP layer, and booting the images contained in the /binary directory.
3Please see the corresponding sections below for details.
4
5The 'Crystal Forest' platform consists of two versions.
61. STARGO
72. SHUMWAY
8
9Stargo Platform is based on Intel Sandy Bridge Gladden Processor,plus the Cave Creek chipset.
10Shumway Platform is based on two Intel Sandy Bridge (SNB-EP ES2 Grade and SNB-EN ES2 Grade)
11Processors plus two Cave Creek Chipsets.
12
13Both Platforms uses Matrox graphics Card.

51I. Building the meta-crystalforest BSP layer
52=======================================
53
54In order to build an image with BSP support for a given release, you
55need to download the corresponding BSP tarball from the 'Board Support
56Package (BSP) Downloads' page of the Yocto Project website.
57
58Having done that, and assuming you extracted the BSP tarball contents
59at the top-level of your yocto build tree, you can build a crystalforest
60image by adding the location of the meta-crystalforest layer to
61bblayers.conf, along with the meta-intel layer itself (to access
62common metadata shared between BSPs) e.g.:
63
64 yocto/meta-intel \
65 yocto/meta-intel/meta-crystalforest \
66
67To enable the Crystal Forest Stargo layer, add the crystalforest-stargo MACHINE to local.conf:
68
69 MACHINE ?= "crystalforest-stargo"
70
71To enable the Crystal Forest Shumway layer, add the crystalforest-shumway MACHINE to local.conf:
72
73 MACHINE ?= "crystalforest-shumway"
74
75
76You should then be able to build a crystalforest image as such:
77
78 $ source oe-init-build-env
79 $ bitbake core-image-sato
80
81At the end of a successful build, you should have a live image that
82you can boot from a USB flash drive (see instructions on how to do
83that below, in the section 'Booting the images from /binary').
84
85As an alternative to downloading the BSP tarball, you can also work
86directly from the meta-intel git repository. For each BSP in the
87'meta-intel' repository, there are multiple branches, one
88corresponding to each major release starting with 'laverne' (0.90), in
89addition to the latest code which tracks the current master (note that
90not all BSPs are present in every release). Instead of extracting a
91BSP tarball at the top level of your yocto build tree, you can
92equivalently check out the appropriate branch from the meta-intel
93repository at the same location.
94
95
96II. Booting the images in /binary
97=================================
98
99This BSP contains bootable live images, which can be used to directly
100boot Yocto off of a USB flash drive.
101
102Under Linux, insert a USB flash drive. Assuming the USB flash drive
103takes device /dev/sdf, use dd to copy the live image to it. For
104example:
105
106To boot the Stargo Platform:
107
108# dd if=core-image-sato-crystalforest-stargo-20120829033154.hddimg of=/dev/sdf
109# sync
110# eject /dev/sdf
111
112To boot the Shumway Platform:
113
114# dd if=core-image-sato-crystalforest-shumway-20120829044852.hddimg of=/dev/sdf
115# sync
116# eject /dev/sdf
117
118This should give you a bootable USB flash device. Insert the device
119into a bootable USB socket on the target, and power on. This should
120result in a system booted to the Sato graphical desktop.
121
122If you want a terminal, use the arrows at the top of the UI to move to
123different pages of available applications, one of which is named
124'Terminal'. Clicking that should give you a root terminal.
125
126If you want to ssh into the system, you can use the root terminal to
127ifconfig the IP address and use that to ssh in. The root password is
128empty, so to log in type 'root' for the user name and hit 'Enter' at
129the Password prompt: and you should be in.
130
131----
132
133If you find you're getting corrupt images on the USB (it doesn't show
134the syslinux boot: prompt, or the boot: prompt contains strange
135characters), try doing this first:
136
137# dd if=/dev/zero of=/dev/sdf bs=1M count=512
