Porting an Automotive Operating System to RISC-V

Tue 02 June 2026 - Roan Richmond

RISC-V is an open instruction set architecture (ISA) in comparison with the proprietary x86 or Arm architectures. Codethink Trustable and Reproducible Linux (CTRL) is an automotive and industrial operating system, which is being actively used today. Therefore, porting CTRL onto RISC-V displays how ready the architecture is to become a major player in the automotive industry. The move to RISC-V has never been easier and supporting this open architecture is the valuable next stage.

We added big‑endian support for an open-source RISC‑V processor and booted Linux on it, using an FPGA board.

To boldly big-endian where no one has big-endianded before

Mon 10 March 2025 - Ben Dooks, Lawrence Hunter, Roan Richmond

Codethink investigates big-endian support on little-endian architectures by exploring RISC-V's new runtime-controllable endianness, with QEMU as testing base.
