   1 Create a Tizen Common x86_64 image with Yocto
   2 =============================================
   3
   4 Target: Haswell CPU
   5
   6 # Create your working directory
   7
   8 Create a working directory (for example "~/yocto"):
   9
  10         mkdir ~/yocto
  11         cd ~/yocto
  12
  13 Create a download directory (optional). It will act as a common download
  14 directory amongst projects:
  15
  16         mkdir ~/downloads
  17
  18 # Download sources
  19
  20 Downlaod Poky:
  21
  22         git clone git://git.yoctoproject.org/poky
  23
  24 Download Intel layers:
  25
  26         git clone git://git.yoctoproject.org/meta-intel
  27
  28 Download openembedded layers:
  29
  30         git clone git://git.openembedded.org/meta-openembedded
  31
  32 Download tizen layer:
  33
  34         git@github.com:eurogiciel-oss/meta-tizen.git
  35
  36 # Configuration
  37
  38 Configure the environment:
  39
  40         cd poky
  41         . ./oe-init-build-env
  42
  43 # Configuration files
  44
  45 ## conf/bblayer.conf
  46
  47 This file contains the list of the layers in which poky has to search
  48 for the recipes.
  49
  50         # LAYER_CONF_VERSION is increased each time build/conf/bblayers.conf
  51         # changes incompatibly
  52         LCONF_VERSION = "6"
  53
  54         BBPATH = "${TOPDIR}"
  55         BBFILES ?= ""
  56
  57         BBLAYERS ?= " \

  72
  73 Most of default values can be kept. The one that needs to be changed is:
  74
  75         MACHINE ?= "haswell-wc"
  76
  77 Other useful option to set:
  78
  79 Download directory:
  80
  81         DL_DIR ?= "${HOME}/yocto/downloads"
  82
  83 Setting the download directory DL_DIR to a directory shared amongst
  84 projects prevents common data from being downloaded for each project.
  85
  86 Terminal emulator:
  87
  88         OE_TERMINAL = "screen"
  89
  90 The terminal emulator you want to use.
  91
  92 Example of a complete configuration file (without comments):
  93
  94         BB_NUMBER_THREADS ?= "${@oe.utils.cpu_count()}"
  95         PARALLEL_MAKE ?= "-j ${@oe.utils.cpu_count()}"
  96         MACHINE ?= "genericx86-64"
  97         DL_DIR ?= "${HOME}/yocto/downloads"
  98         BB_GENERATE_MIRROR_TARBALLS = "1"
  99         DISTRO ?= "poky"
 100         PACKAGE_CLASSES ?= "package_rpm"
 101         EXTRA_IMAGE_FEATURES = "debug-tweaks"
 102         USER_CLASSES ?= "buildstats image-mklibs image-prelink"
 103         OE_TERMINAL = "screen"
 104         PATCHRESOLVE = "noop"
 105         BB_DISKMON_DIRS = "\

 110                 ABORT,${DL_DIR},100M,1K \
 111                 ABORT,${SSTATE_DIR},100M,1K"
 112                 PACKAGECONFIG_pn-qemu-native = "sdl"
 113                 ASSUME_PROVIDED += "libsdl-native"
 114         CONF_VERSION = "1"
 115
 116 # Build the Tizen Common image
 117
 118         bitbake tizen-common-core-image-minimal
 119
 120 Two useful options are:
 121
 122 'k' "Continue as much as possible after an error. While the target that
 123     failed and anything depending on it cannot be built, as much as
 124     possible will be built before stopping."
 125
 126 'v' "Output more log message data to the terminal."
 127
 128 Which gives:
 129
 130         bitbake -kv tizen-common-core-image-minimal
 131
 132 The generate image can be found in tmp/deploy/images/genericx86-64/
