PROFILE
Jonathan Pallant
Over a two-month period, this developer expanded Cortex-R82 support in both the rust-lang/rust and ferrocene/ferrocene repositories, focusing on embedded systems and firmware development. They introduced new aarch64v8r and aarch64r82 target configurations, updated build workflows, and automated testing to ensure robust cross-compilation for Arm architectures. Their work clarified documentation around AArch64 NEON requirements and improved target definitions, enhancing architecture baseline coverage and upstream compatibility. Using Rust, TOML, and Markdown, they enabled safety-critical firmware workflows and streamlined CI processes, allowing Arm ecosystem customers to build and validate Cortex-R82 deployments with improved reliability and broader hardware coverage.

Feb 1, 2026February 2026: Cortex-R82 target support delivered for Ferrocene/ferrocene, introducing aarch64r82-unknown-none and aarch64r82-unknown-none-softfloat. Build workflows, target specs, and testing configurations were updated to automate building and validating the new targets. This expands hardware coverage, enabling Arm ecosystem customers to build and test on Cortex-R82 with parity to existing aarch64 targets. No major bugs fixed this month; primary value lies in broader platform support, CI coverage, and readiness for Cortex-R82 deployments. Technologies demonstrated include cross-target build tooling, CI automation, and close collaboration with Arm/Ferrous Systems.
