The Embedded Linux/Microcontroller project is a port of Linux to systems without a Memory Management Unit (MMU).

Pronounced "you-see-linux", the name uClinux comes from combining the greek letter "mu" and the english capital "C". "Mu" stands for "micro", and the "C" is for "controller". uClinux first ported to the Motorola MC68328: DragonBall Integrated Microprocessor. The first target system to successfully boot is the PalmPilot using a TRG SuperPilot Board with a custom boot-loader created specifically for our Linux/PalmPilot port.

Nice video of a Kinetis module running uClinux. http://www.youtube.com/watch?v=UZjJrLG9CeA. Both Arcturus Networks and EmCraft have system on module solutions that make use of Kinetis parts. If running without external memory buss MQX may be best .. but having uClinux running on another platform is always kewl.

The Freescale Technology Forum held a few session again this year that included support for its ColdFire cores featuring the use of uClinux as its Linux OS. The following link shows a video shot at the event demoing a ColdFire MCF53017 processor running uClinux and CMU's Pocket Sphinx http://www.youtube.com/watch?v=Ahw-vxRaQMA

A bFLT / elf2flt page has been added to the www.uclinux.org site. Right now it acts as a simple jump point to links such as the CVS respository, the wiki page hosted by blackfin.uclinux.org and a link to Craig Peacock's piece on the BFLT Binary Flat Format.

After six months in space the JPLabs ENose project left the International Space Station. This project used a uClinux powered uCdimm (soDIMM form factor system on module) from Arcturus Networks Inc. as its data analysis computer. This module featuring an Freescale Semiconductor ColdFire processor. For more information on the JPL Electronic Nose project can be found at http://enose.jpl.nasa.gov/ The ENose flew for six months on the International Space Station monitoring the air the astronauts breathed.
