From 38f2b670bc37515bcb0fa7f98e338e5242d70386 Mon Sep 17 00:00:00 2001 From: Kishore Bodke Date: Fri, 6 Jan 2012 14:24:26 -0800 Subject: meta-cedartrail: Create new layer for cedartrail System. This layer provides the initial version of the BSP for Cedar Trail platform. The Cedar Trail platform is based on the Cedarview processor and Tiger Point Chipset.

Building the meta-cedartrail BSP layer +========================================= + +In order to build an image with BSP support for a given release, you +need to download the corresponding BSP tarball from the 'Board Support +Package (BSP) Downloads' page of the Yocto Project website. + +Having done that, and assuming you extracted the BSP tarball contents +at the top-level of your yocto build tree, you can build a cedartrail +image by adding the location of the meta-cedartrail layer to +bblayers.conf, along with the meta-intel layer itself (to access +common metadata shared between BSPs) e.g.: + + yocto/meta-intel \ + yocto/meta-intel/meta-cedartrail \ + +To enable the cedartrail layer, add the cedartrail MACHINE to local.conf: + + MACHINE ?= "cedartrail" + +You should then be able to build a cedartrail image as such: + + $ source oe-init-build-env + $ bitbake core-image-sato + +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'). + +As an alternative to downloading the BSP tarball, you can also work +directly from the meta-intel git repository. 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. Instead +of extracting a BSP tarball at the top level of your yocto build tree, +you can equivalently check out the appropriate branch from the +meta-intel repository at the same location. + + +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=core-image-sato-cedartrail-20120105232035.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 -- cgit v1.2.3-54-g00ecf
