Building the meta-sys940x BSP layer + II. Booting the images in /binary + + +I. Building the meta-sys940x 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 sys940x image +by adding the location of the meta-sys940x 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-sys940x \ + +The meta-sys940x layer contains support for two different machine +configurations. These configurations are identical except for the fact +that the one prefixed with 'sys940x' makes use of the Intel-proprietary +EMGD 1.10 graphics driver, while the one prefixed with 'sys940x-noemgd' +does not. + +If you want to enable the layer that supports EMGD graphics add the +following to the local.conf file: + + MACHINE ?= "sys940x" + +The 'sys940x' machine includes the emgd-driver-bin package, which has a +proprietary license that must be whitelisted by adding the string +"license_emgd-driver-bin_1.10" to the LICENSE_FLAGS_WHITELIST variable +in your local.conf. For example: + + LICENSE_FLAGS_WHITELIST = "license_emgd-driver-bin_1.10" + +If you want to enable the layer that does not support EMGD graphics +add the following to the local.conf file: + + MACHINE ?= "sys940x-noemgd" + +You should then be able to build an sys940x 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 (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-sys940x-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 |
