Worked on enhancing watchdog reliability in the flipperdevices/u-boot repository, focusing on scenarios where autostart is disabled during the boot process. Developed and integrated a new helper, wdt_set_force_autostart, to ensure the watchdog is consistently started and maintained across all boot stages. Implemented a runtime check using SMCWD_GET_TIMELEFT to continue pinging an already-active watchdog, reducing the risk of unintended resets during early initialization. Consolidated these improvements to streamline the watchdog subsystem, addressing reliability gaps in embedded systems. The work was carried out using C and leveraged expertise in driver development and watchdog timer management within embedded environments.
