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.

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 |
