1 | This README file contains information on building the meta-sugarbay | ||
2 | BSP layer, and booting the images contained in the /binary directory. | ||
3 | Please see the corresponding sections below for details. | ||
4 | |||
5 | The 'Sugar Bay' platform consists of the Intel Sandy Bridge processor, | ||
6 | plus the Cougar Point PCH (Q67 Express or B65 Express chipsets). This | ||
7 | BSP assumes that the Sandy Bridge integrated graphics are being used. | ||

17 | I. Building the meta-sugarbay BSP layer | ||
18 | ======================================= | ||
19 | |||
20 | For each BSP in the 'meta-intel' repository, there are multiple | ||
21 | branches, one corresponding to each major release starting with | ||
22 | 'laverne' (0.90), in addition to the latest code which tracks the | ||
23 | current master. | ||
24 | |||
25 | In order to build an image with BSP support for a given release, you | ||
26 | need to check out the 'meta-intel' branch corresponding to the release | ||
27 | you're building against e.g. to build for laverne (0.90), check out | ||
28 | the 'laverne' branch of both poky and 'meta-intel'. | ||
29 | |||
30 | Having done that, and assuming you cloned the 'meta-intel' repository | ||
31 | at the top-level of your yocto build tree, you can build a sugarbay | ||
32 | image by adding the location of the meta-sugarbay layer to | ||
33 | bblayers.conf e.g.: | ||
34 | |||
35 | yocto/meta-intel/meta-sugarbay \ | ||
36 | |||
37 | To enable the sugarbay layer, add the sugarbay MACHINE to local.conf: | ||
38 | |||
39 | MACHINE ?= "sugarbay" | ||
40 | |||
41 | You should then be able to build a sugarbay image as such: | ||
42 | |||
43 | $ source poky-init-build-env | ||
44 | $ bitbake poky-image-sato-live | ||
45 | |||
46 | At the end of a successful build, you should have a live image that | ||
47 | you can boot from a USB flash drive (see instructions on how to do | ||
48 | that below, in the section 'Booting the images from /binary'). | ||
49 | |||
50 | |||
51 | II. Booting the images in /binary | ||
52 | ================================= | ||
53 | |||
54 | This BSP contains bootable live images, which can be used to directly | ||
55 | boot Yocto off of a USB flash drive. | ||
56 | |||
57 | Under Linux, insert a USB flash drive. Assuming the USB flash drive | ||
58 | takes device /dev/sdf, use dd to copy the live image to it. For | ||
59 | example: | ||
60 | |||
61 | # dd if=poky-image-sato-live-sugarbay-20101207053738.hddimg of=/dev/sdf | ||
62 | # sync | ||
63 | # eject /dev/sdf | ||
64 | |||
65 | This should give you a bootable USB flash device. Insert the device | ||
66 | into a bootable USB socket on the target, and power on. This should | ||
67 | result in a system booted to the Sato graphical desktop. | ||
68 | |||
69 | If you want a terminal, use the arrows at the top of the UI to move to | ||
70 | different pages of available applications, one of which is named | ||
71 | 'Terminal'. Clicking that should give you a root terminal. | ||
72 | |||
73 | If you want to ssh into the system, you can use the root terminal to | ||
74 | ifconfig the IP address and use that to ssh in. The root password is | ||
75 | empty, so to log in type 'root' for the user name and hit 'Enter' at | ||
76 | the Password prompt: and you should be in. | ||
77 | |||
78 | ---- | ||
79 | |||
80 | If you find you're getting corrupt images on the USB (it doesn't show | ||
81 | the syslinux boot: prompt, or the boot: prompt contains strange | ||
82 | characters), try doing this first: | ||
83 | |||
84 | # dd if=/dev/zero of=/dev/sdf bs=1M count=512 | ||
