Developed Renesas R-Car Gen4 watchdog support for the flipperdevices/u-boot repository, focusing on enhancing platform reliability and deployment readiness for Gen4-based hardware. The work involved implementing CLK_TYPE_GEN4_MDSEL handling in the gen3_clk_get_rate64 function to ensure accurate clock rate calculations, as well as creating a dedicated watchdog driver with configurable timeouts up to 8184 seconds. Integration with Kconfig and Makefile streamlined build and configuration processes. This feature-driven effort demonstrated expertise in C, embedded systems, and kernel development, with particular emphasis on device drivers and watchdog timers, resulting in improved stability and faster validation cycles for supported platforms.
