== Overview of How-To ==
This How-To is meant to be a starting point for people to learn build and run Poky images for IGEP v2 Technology devices as quickly and easily as possible. This How-To works with the '''Ubuntu 8.04 IGEP v2.0 SDK Virtual Machine''' but most of the contents are valid also for other GNU/Linux distributions. We do not issue any guarantee that this will work on other distributions. This How-To will start out by a '''Poky Platform Setup Environment''' introducing you to the Poky environment and the way you can build an Poky-based image. Next, we will cover the '''Poky images supported'''. Lastly, we will learn how to '''Installing and Using the Result on a NFS-mounted root filesystem'''. == Requirements ==*'''Ubuntu 8.04 IGEP v2.0 SDK Virtual Machine''' == Feedback and Contributing ==At any point, if you see a mistake you can contribute to this How-To. === How to get involved (http://pokylinux.org/support/) === There are many ways to get involved with the Poky project. Poky has a friendly community providing informal support and discussion. '''Mailing list''' To subscribe send mail to; poky+subscribe <at> openedhand <dot> com And follow simple instructions in subsequent reply. Archives are available here. '''Bugs''' Problems with Poky should be reported in the bug tracker: http://bugzilla.o-hand.com/ '''IRC''' Chat with the Poky development team and community in #poky on freenode.

== Poky Platform Setup Environment ==
Poky is derivative of the Open Embedded. In order to function properly, the Virtual Machine need some adaptations of the development system. The first thing we need to do is set Bash as default sh shell, execute<pre>$ sudo dpkg-reconfigure dash</pre>and answer no when asked whether you want to install dash as /bin/sh. So, now, "/bin/sh" file links to "/bin/bash" (not to "/bin/dash"). An other change we need to perform is to change some default settings of the kernel. Edit the /etc/sysctl.conf file as root with your preferred editor and set the vm.mmpap_min_addr to 0<pre>$ sudo nano /etc/sysctl.confvm.mmap_min_addr = 0</pre>then, run this command<pre>$ sudo sysctl -p</pre> Install extra packages necessary for bitbake to function.<pre>$ sudo apt-get update$ sudo aptitude install subversion cvs git-core \ build-essential help2man diffstat texi2html texinfo \ libncurses5-dev gawk python-dev python-psyco python-pysqlite2 \ scrollkeeper gnome-doc-utils gettext automake mercurial libx11-dev \ libgl1-mesa-dev libglu1-mesa-dev libsdl1.2-dev</pre> === Poky version 3.2 codename Purple (stable branch) ===Poky version 3.2 ( stable branch) is available from a GIT repository located at git://git.igep.es/pub/scm/poky.git. The first thing you will do is clone the Poky project. <pre>$ git clone git://git.igep.es/pub/scm/poky.gitInitialized empty Git repository in /home/eballetbo/Software/staging/poky/.git/remote: Counting objects: 52944, done.remote: Compressing objects: 100% (16209/16209), done.remote: Total 52944 (delta 34820), reused 52910 (delta 34806)Receiving objects: 100% (52944/52944), 35.52 MiB | 249 KiB/s, done.Resolving deltas: 100% (34820/34820), done.</pre>Then, switch to stable branch (Purple v3.2)<pre>$ cd poky$ git checkout origin/release/purple -b release/purplewarning: You appear to be on a branch yet to be born.warning: Forcing checkout of origin/release/purple.Branch release/purple set up to track remote branch refs/remotes/origin/release/purple.Switched to a new branch "release/purple"</pre>After that, you need to link an user board configuration (local.conf). The configuration file who defines various configuration variables which govern what Poky platform does.<pre>$ ln -s ../../meta-contrib/build/conf/local.conf.igep0020 build/conf/local.conf</pre> At this point the Poky build environment needs to be set up, you will do this image with the poky-init-build-env script. Sourcing this file in a shell makes changes to PATH and sets other core bitbake variables based on the current working directory. Refer to http://www.pokylinux.org/doc/poky-handbook.html#ref-images BSP support for standard images Refer to [[Ubuntu 8.04 IGEP v2.0 SDK Virtual Machine]] to how to install and use poky images on a NFS-mounted root filesystem. === Poky version 3.3 codename Green (under development) === <span style="color: rgb(255given release, 0, 0);">'''Note:''' This is currently work in progress '''Use ONLY for testing and development purposes.'''</span> [http://www.pokylinux.org/releases/green-3.3/doc/poky-handbook.html The Poky handbook guides] users through getting started with Poky and explains how the build system components fit together and interact. The setup and use of the SDK is also covered along with other common development tasks such as debugging and profiling applications. It also contains extensive reference material on many other aspects of Poky such as the classes, variables and other technical details. A customized Poky version 3.3 for IGEP platforms is available from a GIT repository located at git://git.igep.es/pub/scm/poky.git. The first thing you will do is clone the Poky project. $ git clone git://git.igep.es/pub/scm/poky.git $ cd poky At this point the Poky build environment needs need to be set up, you will do this with the poky-init-build-env script. Sourcing this file in a shell makes changes to PATH and sets other core bitbake variables based on the current working directory. $ source poky-init-build-env $ bitbake poky-image-sato ==== Notes, tips and tricks for the new demo image ==== ===== Change default bootargs ===== fw_setenv bootargs-base 'mem=506M console=ttyS2,115200n8 console=tty0 omapfb.mode=dvi:1024x768MR-32@60 omapfb.vram=0:8M,1:4M' ===== Bring up eth0 ===== udhcpc -i eth0 ===== ALSA active the headset path ===== amixer set -D hw:0 'Headset' 6dB amixer set -D hw:0 'HeadsetL Mixer AudioL2' on amixer set -D hw:0 'HeadsetR Mixer AudioR2' on ===== SGX Video Acceleration ===== You can test the SGX with a DEMO, grab and untar the SDK Demo Package wget http://neuvoo.org/neuvoo/distfiles/SGX-3.01.00.07-SDK.tar.gz tar xzf SGX-3.01.00.07-SDK.tar.gz Then to run the demos just get into the X11 Binaries directory (e.g. OGLES/SDKPackage/Binaries/CommonX11/Demos/EvilSkull) and run the demo: ./OGLESEvilSkull ===== DSP using dspbridge ===== fw_setenv bootargs-base 'mem=506M console=ttyS2,115200n8 console=tty0 omapfb.mode=dvi:1024x768MR-32@60 omapfb.vram=0:8M,1:4M' wget http://download.blender.org/peach/bigbuckbunny_movies/big_buck_bunny_480p_surround-fix.avi modprobe mailbox_mach modprobe bridgedriver base_img=/lib/dsp/baseimage.dof phys_mempool_base=0x9FA00000 DISPLAY=:0 gst-launch -v playbin uri=file:/home/root/big-buck-bunny-480p-surround.avi ===== TFT and Touchscreen ===== Seiko 7.0 inch WVGA (800 x RGB x 480) TFT: fw_setenv bootargs-base 'console=ttyS2,115200n8 console=tty0 omapdss.def_disp=lcd-70 omapfb.mode=dvi:1024x768MR-32@60' Powertip 4.3 inch (480 x RGB x 272) TFT: fw_setenv bootargs-base 'console=ttyS2,115200n8 console=tty0 omapdss.def_disp=lcd-43 omapfb.mode=dvi:1024x768MR-32@60' DVI output: fw_setenv bootargs-base 'console=ttyS2,115200n8 console=tty0 omapdss.def_disp=dvi omapfb.mode=dvi:1024x768MR-32@60' Edit the InputDevice section in your xorg.conf cat >> /etc/X11/xorg.conf << EOF Section "InputDevice" Identifier "Configured Touchscreen" Driver "tslib" Option "CorePointer" "true" Option "SendCoreEvents" "true" Option "Device" "/dev/input/touchscreen0" Option "Protocol" "Auto" EndSection EOF Add "Configured Touchscreen" in "ServerLayout" section and remove "Configured Mouse" Section "ServerLayout" Identifier "Default Layout" Screen "Default Screen" InputDevice "Generic Keyboard" # InputDevice "Configured Mouse" InputDevice "Configured Touchscreen" Option "AllowEmptyInput" "no" EndSection Edit /etc/formfactor/machconfig like this HAVE_TOUCHSCREEN=1 HAVE_KEYBOARD=0 calibrate your touchscreen for Powertip 4.3 inch (480 x RGB x 272) TFT: echo -n "8407 -476 -31410144 3 -4861 38051952 655366" > /etc/pointercal for Seiko 7corresponding BSP repository.0 inch WVGA (800 x RGB x 480) TFT: echo -n "13714 0 -56041568 1 -8076 63332096 6553665536" > /etc/pointercal or calibrate it yourself until you are happy with the result, for example: <pre> /etc/init.d/xserver-nodm stop TSLIB_CALIBFILE=/etc/pointercal TSLIB_TSDEVICE=/dev/input/touchscreen0 TSLIB_CONSOLEDEVICE=none ts_calibrate /etc/init.d/xserver-nodm start</pre> ===== Modem =====

On the receiver side: $ source oe-init-build-env
candump can0Having done that, and assuming you downloaded the BSP contentsat the top-level of your yocto build tree, you can build a igepimage by adding the location of the meta-igep layer toconf/bblayers.conf, e.g.:
On the sender side: <path to>/meta-isee \

Switch roles and do again $ bitbake demo-image-sato
At the end of a successful build, you should have a image that you use boot from flash or a micro--- That's all folks ---SD card.
