Grisp: Building Space Ships With Erlang
summary
Grisp ports Erlang/OTP to RTEMS and ships a working board: a 32‑bit embedded image that boots BEAM in 2–6s, runs distributed Erlang over Ethernet, and demonstrates node ping/pong and remote shell sessions. The build currently uses static‑linked native drivers (dynamic linking is pending), mixes C threads for hard‑real‑time with the VM for soft real‑time, and stores releases in NAND (example build uses about 128 MB flash images). Industrial RFID boxes run in the field, customers test it, and new funding supports wider releases.
