CoreCDP 2.0.2 Release Notes

CoreCDP 2.0.2

CoreCDP 2.0.2 was released on November 23, 2011.

CoreCDP 2.0.2 is a major new release and provides updated versions of virtually all software. It also adds support for MultiConnect OCG-E (model MT100EOCG), a new embedded hardware version of the existing box product (MTCDP).

The CoreCDP repository has been restructured to use bitbake layers instead of a custom OpenEmbedded branch. This makes it easier to see CoreCDP-specific changes and also makes it easier to change the OpenEmbedded layer for future releases. OpenEmbedded and bitbake are now part of the CoreCDP repository as git submodules.

  • Based on OpenEmbedded 2011.03 maintenance branch
  • Uses Bitbake 1.12
