Installing Open Embedded Core

This page and instructions is still under construction,but is being made public for your convenience / information. This warning will be removed after a formal release using this process has been made.

The following steps are required for setting up and installing a toolchain, root filesystem and kernel using the OpenEmbedded Core framework (as opposed to the "classic" framework, which is no longer supported). These instructions were developed using a PC running Ubuntu 12.04 using kernel version

Reference Material:

Ubuntu Packages Installed

  • git
  • subversion
  • build-essential
  • automake
  • gawk
  • texi2html
  • texinfo
  • chrpath
  • diffstat
  • gettext
  1. Install the basic OpenEmbedded startup script
    user@host:/export/space/oe$ git clone git://
  2. Modify the default layers to include the MityDSP layer. Edit the setup-scripts/sources/layers.txt file and add the line:
  3. Setup the basic machine configuration (this will download all the meta data, etc):
    user@host:/export/space/oe/setup-scripts$ MACHINE=mityomapl138 ./ config mityomapl138
  4. Modify the generated bitbake layers file (confg/bblayers.conf) to add the meta-mitydsp path. Update the EXTRALAYERS variable to:
     ${TOPDIR}/sources/meta-mitydsp \
  5. At this point, you can now source the generated script and use "bitbake" normally. You can skip the above steps when starting a new build session.
    user@host:/export/space/oe/setup-scripts$ . ~/.oe/environment-oecore
  6. Build the QT Embedded tools and toolchain.
    user@host:/export/space/oe/setup-scripts$ MACHINE=mityomapl138 bitbake meta-toolchain-qte
