PROFILE

Dariusz Sabała

Dariusz Sabala developed and integrated low-level hardware drivers and platform support for the ZynqMP SoC across the phoenix-rtos-devices and phoenix-rtos-project repositories. He implemented PCIe, CAN, UART, SPI, I2C, and PWM drivers, enabling cross-platform peripheral compatibility and flexible console routing. Using C and Makefile, Dariusz standardized configuration macros, improved build systems, and enhanced hardware abstraction layers to support new boards and streamline integration. His work included platform-specific initialization, AXI bus width configuration, and environment hygiene improvements. The depth of his contributions ensured maintainable code, reliable boot processes, and accelerated hardware bring-up for Phoenix-RTOS deployments on ARM platforms.
