PROFILE
Paul Scheffler
Paul Scherrer contributed to the pulp-platform/cheshire repository by developing and refining embedded system features focused on boot reliability, memory management, and hardware-software integration. Over six months, he implemented SPI boot and flashing capabilities, enhanced DMA workflows, and introduced dynamic SD card clocking to improve stability across varying core frequencies. Paul addressed critical bugs in bootrom logic and memory region handling, ensuring robust execution paths and reducing production risk. His work involved C, SystemVerilog, and Makefile, with careful attention to linker scripting and dependency management. These efforts resulted in a more stable, testable platform, supporting smoother releases and broader deployment readiness.

Mar 1, 2025March 2025: Boot reliability improvements for pulp-platform/cheshire. Implemented a bug fix to resolve bootrom fallthrough and boot_next_stage re-entry into platform ROM, corrected a misreferenced relative path, and aligned global assembly symbols to 4-byte boundaries to ensure proper unconditional jump targets. These changes enhance boot reliability, reduce boot failures, and improve platform stability across configurations.
