Worked on enhancing the boot process in the flipperdevices/u-boot repository by implementing boot partition scanning improvements tailored for STM32MP15 DHSOM boards. Developed board-specific substitution logic for the part list within the distro_bootcmd, enabling dynamic configuration based on hardware requirements. Introduced A/B boot schema support, including detection of AB partitions and boot retry logic, to allow seamless switching between rootfs-a and rootfs-b partitions in case of boot failures. Focused on increasing system resilience and reliability, the work leveraged expertise in C programming, embedded systems, and device tree configuration to deliver robust bootloader enhancements without introducing new bugs.
