LiteBSD is a variant of 4.4BSD operating system adapted for microcontrollers. Currently, only the Microchip PIC32MZ family is supported as a target. It is equipped with MMU with paging support, and 512kbytes of on-chip RAM. These resources are enough to build a compact networked embedded system.

PIC32-HMZ144 support is on the LiteBSD Github
