Worked on enhancing TFTP configuration flexibility in the flipperdevices/u-boot repository by removing the CONFIG_TFTP_PORT option, allowing TFTP ports to be configured unconditionally. Used C programming and embedded systems expertise to ensure the tftpdstp and tftpsrcp variables are always effective, which streamlines deployments in non-root environments and eliminates the need for bootloader rebuilds when port changes are required. Updated documentation to reflect these changes and aligned U-Boot’s behavior with upstream standards, simplifying ongoing maintenance. The work focused on bootloader development and addressed a specific deployment pain point, delivering a targeted feature without introducing new bugs during the period.
