This README file contains information on building the meta-emenlow
BSP layer using any of the supported machine configurations, and
booting the images contained in the /binary directory.
If you're only interested in booting the images in the /binary
directory of a BSP tarball you've downloaded, there's nothing special
to do - the appropriate images are already in the /binary directory
depending on which BSP tarball you downloaded.
Please see the corresponding sections below for details.

I. Building the meta-emenlow BSP layer
=======================================
In order to build an image with BSP support for emenlow, you just need
to check out the poky master branch.
Having done that, you can build an emenlow image by adding the
location of the meta-emenlow layer to bblayers.conf e.g.:
yocto/meta-emenlow \
To enable the emenlow layer, add the emenlow MACHINE to local.conf:
MACHINE ?= "emenlow"
You should then be able to build an emenlow 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-emenlow-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
