From 2deb57956fc6a721c46c67bcdf844ed29c71f3a3 Mon Sep 17 00:00:00 2001 From: Tom Zanussi Date: Mon, 31 Jan 2011 01:05:15 -0600 Subject: meta-sugarbay: new layer for Sandy Bridge/Cougar Point systems This layer provides support for Sandy Bridge + Cougar Point Intel systems. The 'Sugar Bay' platform consists of the Intel Sandy Bridge processor, plus the Cougar Point PCH (Q67 Express or B65 Express chipsets). This BSP assumes that the Sandy Bridge integrated graphics are being used, and makes use of the grub2 and associated live-install changes in meta-intel/common.

Special notes for building the meta-sugarbay BSP layer +III. Booting the images in /binary + + +I. Building the meta-sugarbay BSP layer +======================================= + +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. + +In order to build an image with BSP support for a given release, you +need to check out the 'meta-intel' branch corresponding to the release +you're building against e.g. to build for laverne (0.90), check out +the 'laverne' branch of both poky and 'meta-intel'. + +Having done that, and assuming you cloned the 'meta-intel' repository +at the top-level of your yocto build tree, you can build a sugarbay +image by adding the location of the meta-sugarbay layer to +bblayers.conf e.g.: + + yocto/meta-intel/meta-sugarbay \ + +To enable the sugarbay layer, add the sugarbay MACHINE to local.conf: + + MACHINE ?= "sugarbay" + +You should then be able to build a sugarbay 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-sugarbay-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 -- cgit v1.2.3-54-g00ecf
