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
