Blog
In this blogpost we will cover how to bring CVA6 processor up with Linux on it and how we replaced the OS there with a different one, based on Freedesktop SDK, updating the kernel version on the way.
Exploring how Codethink used embedded Rust to measure Linux’s scheduling performance with an external clock, while maintaining bit-for-bit reproducibility of the testing firmware.
Our latest blog post provides an overview of the Trustable Software Framework and how it's applied.
Software is never a temporary feature, especially in the fast-moving world of embedded systems. In industries like automotive, software is at the core of the product’s function, but time and time again, companies treat it like a short-term asset.
Codethink dives into the Linux vs. QNX debate—focusing on architecture, performance, scalability, and long-term production viability.
Three years ago, we co-presented about Rust's readiness for use in Automotive Safety contexts, let's look back at that and then consider the future.
After Codethink's milestone on safe open source in safety-critical systems, we joined two workshops in Lund to explore the journey further.
Join Codethink at RISC-V Summit Europe 2025 for a talk on runtime-configurable endianness in RISC-V and a poster session.
Explore the EU Cyber Resilience Act (CRA), its impact on businesses and affected sectors, its implementation, and penalties for non-compliance.
Codethink's John Ellis joins the Embedded Insiders podcast for 'The Road Ahead: Automotive Tech, Standards, and Safety for 2025'. Tune in here.
