Worked on enhancing bootloader configurability for LS series boards in the flipperdevices/u-boot repository, focusing on embedded systems and C programming. Developed and standardized new boot environment variables, including image, extra_bootargs, othbootargs, and console_dbg, to streamline boot customization and improve debugging across LS1028ARDB, LS1043ARDB, LS1046ARDB, and LX2160ARDB boards. Updated board-specific settings, such as setting the LX2160ARDB console baud rate to 115200, to support more reliable debugging. Delivered these improvements through a cohesive set of commits, establishing a maintainable and consistent cross-board boot configuration workflow that enhances flexibility and debuggability for future development.
