The 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.

The uClinux Project founders and principal maintainers are proud to announce the uClinux project will join the Open Innovation Network Patent Pool. If you use uClinux, this means you will be safer than ever from attack by Patent Trolls. -- D. Jeff Dionne et al.
