Arm SystemReady IR

SystemReady IRSystemReady IR is a band of system certification in the Arm SystemReady program.

SystemReady IR is tailored to meet the needs of embedded Linux/BSD ecosystem on systems based on embedded Arm SoCs. It ensures standard firmware interfaces to deploy and maintain. It assumes SoC supported by mainline Linux/BSD. It targets both custom (Yocto, OpenWRT, buildroot) and pre-build (Debian, Fedora, SUSE) images.

SystemReady IR certified platforms implement a minimum set of hardware and firmware features that an operating system can depend on to deploy the operating system image. Compliant systems must conform to the:



Compliance to the Arm Base System Architecture (BSA) specification is also recommended. The SystemReady IR certification and testing requirements are specified in the  Arm SystemReady Requirements Specification (SRS).

What Version of SystemReady IR is the Best Choice?

Arm is committed to assessing the market and adjusting standards towards a frictionless ecosystem. As SystemReady IR has matured in boot and installation capabilities, we’ve added more requirements to address maintenance and security level capabilities. In the new SystemReady IR2.0, the focus has been in providing a better long term compatibility between platforms and OS, so that new OS versions do not break on older platforms/ It also adds support for secure firmware over-the-air (OTA) updates and Unified Extensible Firmware Interface (UEFI) secure boot. You can use the table below to assess which version of SystemReady IR is the best fit for your product.

Partners Testimonials

NXP logo

“At NXP, our mission is to enable our customers to reduce development time and maintenance costs, or secure cloud to edge applications, NXP recognized early on the value of Arm’s SystemReady and PSA certifications to provide software and security building blocks necessary for accelerating time-to-market. And therefore, we sought certification of our popular i.MX 8M applications processors family which is now the first to be SystemReady IR certified.”

- Rob Oshana, VP of SW, NXP Semiconductors.

SECO logo

“For SECO and our customers, the benefit of participating in the Project Cassini is twofold. First, it enables seamless and therefore fast integration of our SystemReady certified devices into larger systems and networks, which can be used by a broad ecosystem of partners in many different markets. Second, being also a software solutions provider, SECO can become an active part of this ecosystem by opening our software offering to third parties. By joining Project Cassini, we once again demonstrate that at SECO, standardization, security and openness are essential principles.”

- Marco Sogli, Head of SW R&D & DevOps at SECO
