Building the meta-crownbay 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 crownbay +image by adding the location of the meta-crownbay layer to +bblayers.conf e.g.: + + yocto/meta-intel/meta-crownbay \ + +To enable the crownbay layer, add the crownbay MACHINE to local.conf: + + MACHINE ?= "crownbay" + +You should then be able to build a crownbay 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. Special notes for building the meta-crownbay BSP layer +========================================================== + +The meta-crownbay layer makes use of the proprietary Intel EMGD +userspace drivers, which at this point in time require that the user +accept the Intel license by manually extracting the binaries and +copying them to the proper location in the meta-crownbay layer. + +There currently isn't an automated way to do this, thus the manual +step. When Yocto supports a click-through installation mechanism, the +binary files will be packaged as part of the recipe, and this step +will be unnecessary. + +These steps require that you run a graphical application in Windows. +Windows 7 was used for these instructions, but it shouldn't matter +which version of Windows you use. + +The first step of the process is to download the EMGD 1.5 Gold Driver. +Here is the current link to the URL which it can be downloaded from: + +http://edc.intel.com/Software/Downloads/EMGD/ + +In the Download Now tab, select: + +Intel® architecture-based product: Intel Atom Processor E6XX Series +Operating System: MeeGo 1.0 IVI Linux (kernel 2.6.33.3, X.server 1.8.0) + +That will give you a large zip file: + +IEMGD_1_5_GOLD_ALL_1742.zip + +Extract the files in the zip file, which will in turn give you a large +.exe file: + +IEMGD_1_5_GOLD_ALL_1742.exe + +Run IEMGD_1_5_GOLD_ALL_1742.exe to install, accept licenses, etc. + +If it says to install watcom, follow the instructions to do that. + +When the installation completes, an application named "emgd-ced" will +be present in the install directory. Double-click to run it. + +Select the menu item: New Configuration + +In the tabbed page, make the following selections and/or enter the +specified data: + +Configuration File Name: myconfig +Platform Chipset: Intel Atom Processor E6xx +Port Devices: LVDS, sDVO + +Hit the 'Next' button. + +On the next tabbed page, make the following selections and/or enter +the specified data: + +Readable Port Name: portname0 +Encoder Configuration: Select sDVO Device: Internal LVDS + +Hit the 'Finish' button. + +Select the menu item: New Package + +In the tabbed page, make the following selections and/or enter the +specified data: + +Package File Name: mypackage +Configurations: selec myconfig.cnfg +Target OS: Linux operating System + +Hit the 'Finish' button. + +Select the menu item: Generate Installation + +This will create the EMGD installation package: + +Generating EMGD installation... + +The installation package should now be under the 'workspace' +subdirectory of the directory you installed to: + +workspace/installation/mypackage.pkg_installation/IEMGD_HEAD_Linux/IEMGD_HEAD_Linux.tgz + +This is the file you are interested in. Copy it to your Poky build +system, and uncompress/untar it: + +$ tar cvfz IEMGD_HEAD_Linux.tgz + +Finally, copy Xorg-xserver binaries in the Meego1.0 driver directory +to the xserver-xf86-emgd-bin directory in the meta-crownbay layer: + +$ cp IEMGD_HEAD_Linux/MeeGo1.0/driver/Xorg-xserver-1.7.99/* meta-crownbay/recipes/xorg-xserver/xserver-xf86-emgd-bin + +You also need to copy the IEMGD License.txt file to the same directory: + +$ cp IEMGD_HEAD_Linux/License/License.txt meta-crownbay/recipes/xorg-xserver/xserver-xf86-emgd-bin + +At this point, you should be able to build meta-crownbay images as usual. + +---- + +For reference, the EMGD Driver documentation is also available at the +above link (it's also part of the installation). + +The specific text of the document is: + +User Guide: Intel® Embedded Media and Graphics Driver, EFI Video +Driver, EPOG, and Video BIOS v1.5 for Windows* XP and Linux* Provides +installation requirements/procedures & describes the vbios/firmware, +configuration options, & functionality of Intel® EMGD under Windows* & +Linux*. Refer to guide for details. + +File Type/Size: PDF 3,340KB +Version: 008 : October 2010 + + +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-crownbay-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 |
