EoS Kernel
EmbeddedOS
Kernel
A deterministic, real-time operating system kernel built for resource-constrained devices. Fixed-priority preemptive scheduling, a modular driver model, a POSIX-compatible API, and 83 boards across 55 architectures.

Kernel Features
What makes EoS different from other RTOS platforms
Deterministic Scheduling
Fixed-priority preemptive scheduling with configurable tick rates, so worst-case response is bounded rather than average.
Secure Boot Chain
eBoot verifies every stage cryptographically. Tampered firmware cannot run.
Modular Driver Model
Add or remove drivers without recompiling the kernel. Hot-plug on supported platforms.
POSIX-Compatible API
Port existing POSIX applications to EoS with minimal changes. Standard threads, mutexes, and sockets.
EoS Language
The fastest embedded API surface — direct memory-mapped register access with type safety.
83 Board Definitions
STM32, ESP32, nRF52, RISC-V, i.MX RT, Raspberry Pi Pico and 77 more, spanning 55 instruction-set architectures.
