ELinOS 7.2 released

ELinOS, IoT, Linux

ELinOS 7.2, our latest Linux-based operating system tailored for embedded systems, has improved features that meet a variety of development needs. The new version introduces support for RISC-V, offering a cost-effective alternative to ARM-based platforms. Initial backing for Microchip's PolarFire SoC Icicle ensures seamless operation beyond 2038, addressing the critical year 2038 bug across all architectures.

In response to the escalating relevance of Software Bill of Materials (SBOM), ELinOS now generates licenses in SPDX format, facilitating comprehensive project analysis. We offer strengthened integration with our PikeOS RTOS & Hypervisor and expanded support for Immutable OS streamline project development, aided by an intuitive Eclipse-based IDE CODEO. Enhanced security measures include backing for Intel's Control Flow Enforcement Technology (CET).

Furthermore, ELinOS 7.2 incorporates updated toolchains, featuring GCC 12.2 and binutils 2.4, aligning with future legislative mandates like the Cyber Resilience Act (CRA). These advancements ensure ELinOS remains at the forefront of embedded system development, empowering developers to craft reliable and high-performance solutions.
