Worked on the UWOrbital/OBC-firmware repository to optimize the bootloader, focusing on reducing its memory footprint to comply with strict address boundaries. Applied code-size optimizations and removed unused sections, ensuring the bootloader remained reliable and fully validated. Utilized C and CMake to implement these changes, leveraging expertise in embedded systems, firmware development, and memory management. Validation was performed using Uniflash and physical hardware board testing to confirm that no regressions were introduced and that real-world behavior matched expectations. This work preserved valuable flash and RAM headroom, reducing the risk of memory-related failures and supporting future feature expansion within the system.
