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

  65         #For Arch haswell
  66         #BBLAYERS_append = "${WORKINGDIR}/meta-intel/meta-haswell-wc "
  67         #For Arch Ivy
  68         BBLAYERS_append = "${WORKINGDIR}/meta-intel/meta-romley "

  70 ## conf/local.conf
  71
  72 Most of default values can be kept. The one that needs to be changed is:
  73
  74         #For qemu
  75         MACHINE ?= "qemux86-64"
  76         #For haswell
  77         MACHINE ?= "haswell-wc"
  78         #For Ivy
  79         MACHINE ?= "romley-ivb"
  80
  81 Other useful option to set:
  82 Download directory:
  83         DL_DIR ?= "${WORKINGDIR}/downloads"
  84
  85 Setting the download directory DL_DIR to a directory shared amongst
  86 projects prevents common data from being downloaded for each project.
  87
  88 Terminal emulator:
  89         OE_TERMINAL = "screen"
  90
  91 The terminal emulator you want to use.

  94 1)
  95   sudoedit /etc/sudoers
  96   ronanguirec ALL=(ALL) NOPASSWD: ALL

  98 2)
  99   bitbake tar-replacement-native
 100
 101 # Build the Tizen Common image
 102         tizen-common-core-image-minimal-dev
 103
 104 Which gives:
 105         1) bitbake -kv tizen-common-core-image-minimal-dev
 106         2) runqemu qemux86-64 tizen-common-core-image-minimal
 107
 108 The generate image can be found in tmp/deploy/images/${MACHINE}
