In 2006 CodeGen, Inc released their Open Firmware implementation under a BSL like license. Their code, entirely written in ANSI C, contains the following components:

  • SmartFirmware™: an ANSI C implementation of the IEEE-1275 Open Firmware boot firmware standard. Dramatically reduce and ease your firmware development and system bring-up times and costs.
  • An ANSI C compiler that generates Open Firmware compatible Forth/Fcode makes it easy to develop drivers for PCI cards and PMC modules.


You can browse the code online.

The repository is available through Subversion:

You can check it out as follows:

 $ svn co svn://

if you want a specific revision:

 $ svn co svn:// -r 1

If your company installed a firewall that blocks the svn port (3690) you can also check out using the webdav frontend:
