Worked on stability and hardware integration for the Phoenix-RTOS ecosystem, focusing on USB protocol handling and embedded systems using C. Delivered a fix in phoenix-rtos/libphoenix to address pointer arithmetic in temporary file generation, reducing runtime risks and improving reliability. Coordinated submodule updates in phoenix-rtos-project to integrate STM32N6 USB driver support, enhancing device communication and cross-repository alignment. In phoenix-rtos-devices, addressed a critical bug in the STM32N6 USB client by correcting DAINT register handling, ensuring proper atomic operations for USB endpoints. The work emphasized robust system programming practices and contributed to smoother production deployments across multiple hardware targets.
