Angstrom Linux
The Angstrom Linux operating system (Version 2.6.32) is compiled and linked independently of the
ODV-2D application and tailored for embedded devices and shipped with the BeagleBoard-xM and
BeagleBone. Information about Angstrom Linux can be found at http://www.angstrom-distribution.org/.
Changes have been made to Angstrom Linux modules and thus based on the

Linux Boot Loader
The Linux Boot Loader (U-Boot) (Version 2011.06) is compiled and linked as a separate program within
the ODV-2D system and not directly linked to the application. Its purpose is to load and start the Linux
operating system and setting any necessary environment variables. Information about U-Boot can be
found at http://beagleboard.org/project/angstrom.
