Zephyr Project: An RTOS to Change the Face of IoT
summary
Zephyr is an open RTOS aimed at tiny IoT nodes that emphasizes static allocations to cut footprint and boot time, is Apache 2 licensed and hosted by the Linux Foundation after Wind River donated the code, and already supports multiple architectures (ARM Cortex‑M, others in progress). The security argument distinguishes device versus network/logical threats, warns that OTA/DLM is only the last mile of patching, and proposes baking provenance, hardening and continuous maintenance into upstream workflows so certified downstream products don’t rot.
