Daniel Sawka developed robust embedded features and system enhancements across the Phoenix-RTOS ecosystem, focusing on inter-CPU communication, device I/O, and system reliability. Working in C and Shell within repositories like phoenix-rtos-devices and phoenix-rtos-kernel, he implemented mailbox-based inter-core drivers, FIFO pipes over shared memory, and dynamic watchdog management to improve cross-core data transfer and runtime stability. Daniel addressed build and clock management issues by refining linker scripts, conditional compilation, and HAL clock logic, reducing power draw and build errors. His work demonstrated depth in low-level programming, RTOS integration, and hardware abstraction, delivering maintainable solutions for evolving platform requirements.

November 2024 overview: Delivered key reliability and configurability improvements across the Phoenix-RTOS ecosystem, focusing on watchdog stability, system-wide reliability, cross-platform RTT memory management, and scripting enhancements. Highlights include WDOG1 auto-reload and dynamic timeout on i.MX RT, a new watchdog CLI for runtime visibility, RTT memory configurability across iMX RT platforms, switching the global watchdog to WDOG1 on imxrt117x for persistent monitoring, and enabling Lua scripting by default for ia32-generic builds. These changes improve stability during long-running tasks, reduce debugging overhead, and provide flexible memory/resource configuration across devices.
