STK is MIT-licensed. For production, regulated and mission-critical products, we offer components and services that shorten time-to-market and de-risk adoption.
Kernel in the Secure binary scheduling both Secure and Non-Secure tasks. CMSE-checked NSC gateways, task and sync-object wrappers, and a drop-in Non-Secure Kernel facade with the familiar STK API. Developed on Cortex-M23/M33/M55/M85 class cores.
Mixed-criticality adaptive scheduling: 2-level (LO/HI) and 4-level, SWRR group scheduling, automatic cascade escalation and recovery, elastic CPU-share adaptation from per-group execution-pressure estimates.
The open-source driver already supports Secure-only TrustZone scheduling and independent Secure / Non-Secure MPU hardening.
IP indemnification and provenance guarantees for corporate legal departments.
Assistance toward IEC 61508, IEC 62304, ISO 26262 or DO-178C.
Enterprise License Agreements for strict open-source procurement policies.
Code audit and licensing assessment.
Specialized Arm, RISC-V or other architectures and SoCs.
Hard real-time optimization, latency profiling, jitter reduction.
USB, I2S/TDM audio, networking stacks, DMA engines.
Guaranteed response times and priority escalation.
Code reviews, system design and reliability analysis.
Versioned updates, patch management, minor feature requests.
Remote workshops and RTOS best practices for your team.
