[OxidizeConf2024] Leveling Up Hardware Production with Rust
Revolutionizing Hardware Manufacturing
The landscape of hardware manufacturing has long been constrained by proprietary tools provided by chip vendors, often treated as opaque systems that limit developer control. Ryan Summers from Forged.dev delivered an engaging presentation at OxidizeConf2024, showcasing how Rust and the Probe.rs library are transforming hardware production processes. With a background in safety-critical embedded systems, including medical devices like neurostimulators, Ryan illustrated how Rust’s modern tooling empowers developers to achieve precise control over device programming, moving beyond the limitations of traditional black-box solutions.
Ryan’s talk focused on the production process for a hypothetical Bluetooth-enabled pacemaker, highlighting the need for meticulous device provisioning and testing. In traditional manufacturing, tasks like assigning serial numbers, calibrating sensors, and programming firmware rely on vendor-supplied binaries with limited customization options. Probe.rs, an open-source Rust library, changes this paradigm by offering fine-grained memory control, enabling developers to tailor device configurations and integrate them into automated production workflows. This approach ensures higher quality and reliability, particularly for safety-critical applications where failures are not an option.
The Power of Probe.rs
Central to Ryan’s presentation was the Probe.rs library, which redefines how developers interact with microcontrollers during production. Unlike vendor-supplied tools that restrict operations to basic flashing and erasing, Probe.rs provides a programmatic interface for memory manipulation and direct communication with devices. Ryan demonstrated how this enables tasks like assigning unique Bluetooth addresses and storing calibration data in external memory chips, streamlining the provisioning process. The library’s flexibility allows manufacturers to integrate these tasks into automated systems, reducing errors and improving efficiency.
Moreover, Probe.rs extends beyond manufacturing to support advanced use cases like embedded testing and performance profiling. Ryan highlighted the emerging embedded-test feature, which allows unit tests to run directly on hardware, a boon for validating safety-critical systems. By leveraging Rust’s type safety and memory guarantees, Probe.rs minimizes the risk of errors during programming, ensuring that devices meet stringent quality standards. This capability is particularly valuable in medical and automotive industries, where precision is paramount.
Scaling Production with Rust
Ryan also discussed scaling hardware production with Rust, addressing both small-scale and high-volume manufacturing. For safety-critical devices, such as pacemakers, every unit must undergo rigorous testing to detect defects like cold solder joints or short circuits. Probe.rs facilitates this by enabling automated testing workflows that integrate with production lines, ensuring consistent quality. Ryan noted that while some consumer markets may prioritize speed over quality, safety-critical sectors demand the precision that Rust and Probe.rs deliver.
For large-scale production, Ryan and Probe.rs founder Noah collaborated on Forged.dev Marinas, a tool designed to manage firmware deployment, serial number assignment, and cloud-based data storage. This solution caters to manufacturers needing to comply with regulations like FDA standards, ensuring traceability and accountability. Ryan’s insights underscored Rust’s potential to unify development and production processes, offering a cohesive ecosystem that contrasts with the fragmented tools of traditional manufacturing.
