Introduction

LK (Little Kernel) is a tiny operating system suited for small embedded devices, bootloaders, and other environments where OS primitives like threads, mutexes, and timers are needed, but there’s a desire to keep things small and lightweight. On embedded ARM platforms the core of LK is typically 15-20 KB.
