From 43b2e9c34363ade4241a60f699b47179929c6fb6 Mon Sep 17 00:00:00 2001 From: Darren Hart Date: Mon, 29 Oct 2012 11:48:06 -0700 Subject: n450: Add WEBTITLE and boilerplate README The WEBTITLE will be used to publish the BSP on the Yocto Project website. Add a boilerplate README including the Yocto Project compliance information for the 1.3 release.

Building the meta-n450 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 an n450 +image by adding the location of the meta-n450 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-n450 \ + +Configure your build to build for the n450 machine in your local.conf file: + + MACHINE ?= "n450" + +You should then be able to build an n450 image as such: + + $ 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 (note that +not all BSPs are present in every release). 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-n450-20101207053738.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 diff --git a/meta-n450/conf/machine/n450.conf b/meta-n450/conf/machine/n450.conf index 7ce4cc70..da545612 100644 --- a/meta-n450/conf/machine/n450.conf +++ b/meta-n450/conf/machine/n450.conf @@ -1,7 +1,9 @@ #@TYPE: Machine #@NAME: n450 -#@DESCRIPTION: Machine configuration for Intel 1-N450 based systems +#@WEBTITLE: Intel Atom N450 Processor with Intel 82801 HM I/O Controller Compute Module (Luna Pier) with Intel Compute Module Mini-ITX Carrier + +#@DESCRIPTION: Machine configuration for Intel Embedded Development Board 1-N450 PREFERRED_PROVIDER-virtual/kernel ?= "linux-yocto" PREFERRED_VERSION_linux-yocto ?= "3.2%" -- cgit v1.2.3-54-g00ecf
