The first article of the Grits Programmable I/O board and the revised version of the Cornbread Programmable I/O board have been built. Pictures are available on the Grits Programmable I/O page.

Design for Grits Programmable I/O Board Released
The Grits Programmable I/O board has been released as source and manufacturing files. This board is built in the PC/104 embedded computer format. Programmable inputs and outputs are accessed through one or more I/O addresses, and a switchable interrupt is provided. Full design files are provided, along with manufacturing files for the board. The schematic and printed wiring board CAD files are being initially released for the GNU/Linux platform and the Eagle 4.01 CAD system. As usual, the design and all of its files are released under GPL. The link is on the Grits Programmable I/O page.
GNU/Linux Eagle 4.01 CAD Design for Cornbread Board Released
The Cornbread Board has been updated, and the design brought onto the GNU/Linux platform and the Eagle 4.01 CAD system. Full design files are provided, along with manufacturing files for the board. As usual, the design and all of its files are released under GPL. The link is on the Cornbread Programmable I/O page.
GNU/Linux Driver for Cornbread and Flapjack Boards Released
Tim Spence has contributed GNU/Linux user space driver code for the Cornbread Board. This code also works for the Flapjack Board, since that is a proper subset of the Cornbread Board. Thanks, Tim!
Biscuit ColdFire Embedded Control Board Processor Type Changed
After considerable deliberation, it was decided to change the processor for the Biscuit board to a Motorola MCF5272. This device has several devices built in which will simplify use of the processor in embedded “ethernet appliance” applications. The deciding factor was the built in 10/100 Mbs ethernet MAC. The MCF5272 documentation is even more thorough than usual for Motorola.
Snapshot of uClinux/Coldfire Web Site Added
The Moreton Bay web site has had operating uClinux/ColdFire source and binary for common ColdFire boards for a couple of years. Unfortunately, it is nearly impossible to find since their top level site points to the Lineo main page. We now have a link to it on the Links page, and we have also put up a snapshot of it. We would mirror it except that we do not have such privileges on our server.
