Worked on the flipperdevices/u-boot repository to enhance bootloader reliability and configuration management for embedded RISC-V systems. Focused on stabilizing the Falcon SPL boot path by correcting the FIT image name to linux.itb, which resolved boot failures and improved maintainability through explicit image handling. Addressed device-tree misconfiguration by removing an erroneous fdt_high environment variable, ensuring accurate FDT detection and cleaner configuration hygiene. Delivered targeted, well-documented bug fixes using C, demonstrating expertise in bootloader development and embedded systems. The work emphasized precise, low-risk changes that improved boot-time behavior and maintainability without introducing new features, reflecting a methodical engineering approach.
