Several BBFILE_COLLECTIONS assignments in the layer.confs for these meta-intel layers added unwanted machine overrides, resulting in truncated values for this variable - remove them. Signed-off-by: Tom Zanussi <tom.zanussi@intel.com> |

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

I. Building the meta-jasperforest 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 jasperforest image by adding the location of the meta-jasperforest layer to bblayers.conf e.g.:
yocto/meta-intel/meta-jasperforest \
To enable the jasperforest layer, add the jasperforest MACHINE to local.conf:
MACHINE ?= "jasperforest"
You should then be able to build a jasperforest 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. 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-jasperforest-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:
