PROFILE
Ben Stoltz
Worked on the oxidecomputer/hubris repository, delivering features and fixes that enhanced embedded system reliability and hardware integration. Developed a GPIO Pin Interrupt API for the LPC55 microcontroller, enabling event-driven task activation through external pin interrupts and refining configuration management for maintainability. Implemented a flash bank measurement feature triggered by SP_RESET, utilizing RAM injection and SHA3-256 hashing to improve security verification. Addressed build failures by increasing stack size for network tasks and improved system update robustness with version translation fixes. Leveraged Rust and TOML, applying skills in driver development, cryptography, and low-level programming to ensure stable, secure firmware operations.

Mar 1, 2025March 2025: Delivered a feature for the hubris repository that enables flash bank measurement triggered by SP_RESET, including RAM injection, execution of a measurement program in SP RAM, and retrieval of the SHA3-256 hash of the flash bank. The work also set up handling for SP reset and JTAG-detection interrupts with robust SWD state management and error handling.

Nov 1, 2024November 2024: Delivered a stability fix in oxidecomputer/hubris to address a build failure when compiling all applications by increasing the stack size for task-net in the app management configuration. This change, committed as a842b3c0c96664b0dcdf785f01c832cc523ed992 (PR #1923), reduces CI flakiness and enables successful multi-app builds. Result: smoother deployments, fewer manual interventions, and improved reliability of network task handling.
