meta-emenlow: update to the new BSP layout
This modifies the meta-emenlow BSP layer to reflect the new BSP standard layout as defined in the latestYocto BSP Developer's Guide. There's no change in functionality here - this simply moves things around, adds a README, and makes the SRCREVs local. Signed-off-by: Tom Zanussi <tom.zanussi@intel.com>

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
