1 | This README file contains information on building the | ||
2 | meta-jasperforest BSP layer, and booting the images contained in the | ||
3 | /binary directory. Please see the corresponding sections below for | ||
4 | details. | ||
5 | |||
6 | 'Jasper Forest' refers to the Intel Xeon C5500/C3500 processors, which | ||
7 | combined with the Intel 3420 PCH chipset (Ibex Peak) make up the | ||
8 | 'Picket Post' CRB this BSP was developed on. | ||

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