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 3Com PalmPilot using a TRG SuperPilot Board with a custom boot-loader created specifically for our Linux/PalmPilot port. It is currently maintained by co-creator D. Jeff Dionne.
