μClinux is a variation of the Linux kernel, previously maintained as a fork, that targets microcontrollers without a memory management unit (MMU). It was integrated into the mainline kernel as of 2.5.46 (2007) in the form of a NOMMU option.
After the mainline merge, the μClinux project continued to develop patches and tools for microcontrollers. The last Wayback Machine archive of the homepage (from 2018) lists Linux kernel releases for 2.0, 2.4 and 2.6 (all of which are end-of-life in mainline, 2.6 being the last to go in 2016), with the last news entry dated May 2016 concerning a new release of the kernel distribution. The website remained unchanged through 2021, when it went offline.
The letters "μC" are for "microcontroller": the name is pronounced "you-see-Linux", rather than pronouncing the letter mu as in Greek.
