Nerves - Getting Started, and the Road Ahead
summary
Nerves powers real shipping devices for marine navigation, claims rock‑solid stability with no memory leaks and steady ~28 MB RAM usage, and produces a compact 18 MB firmware that boots in 4–5 seconds. The stack cross‑compiles via buildroot into dual read‑only partitions for safe OTA updates; tooling called bake lets macOS and Linux desktops build firmware locally without VMs. Supported boards include BeagleBone Black and Raspberry Pi families; ongoing work covers Wi‑Fi/Bluetooth, UI via Elm, and service discovery/security.
