# LinRT — Real-Time Linux Yocto BSP

> LinRT provides Real-Time Linux Yocto Board Support Packages for selected NXP i.MX System-on-Modules. Its product families are Oxygen (PREEMPT_RT), Cobalt (Xenomai 3 / RTDM) and Tungsten (Xenomai 4 / EVL).

LinRT is provided by Digital Data Software, LLC. Technical support and source access are available under annual subscription arrangements. Hardware support is qualified per SoM, board and distribution; not every variant is available on every platform.

Mercury is discontinued as a LinRT product name and replaced by Tungsten. Avoid confusing the discontinued LinRT product with Xenomai's similarly named historical kernel mode. Refer to the current distribution pages for authoritative product naming.

## Platforms and roadmap

- NXP System-on-Module families considered: i.MX6QDL, i.MX8MP, i.MX91, i.MX93 and i.MX95.
- LinRT 5.3 is planned for Q4 2026 with a CRA-Ready positioning; LinRT 5.x support is planned through the end of 2028.
- LinRT 6.0 is planned for Q1 2027, including planned i.MX95 support. LinRT 6.x updates are targeted every six months, with a prospective end of life at the end of 2031.
- The CRA Certification Kit is planned for early 2027 alongside LinRT 6.x. It aims to help manufacturers assemble SBOM, CVE/VEX, verification and traceable technical evidence. It is not a CRA certificate and does not by itself certify a finished product.
- All roadmap dates and support statements are targets subject to confirmation; no unqualified performance, availability or certification claims should be inferred.
