Over five months, contributed to the levizh/rt-thread repository by developing and enhancing embedded networking and device driver features using C and Assembly. Delivered per-network-device DNS configuration, improved WLAN station and access point information APIs, and expanded network diagnostics through a detailed ping utility. Integrated CherryUSB to support USB host and device classes, and strengthened ARM Cortex-M33 interrupt handling with BASEPRI-based masking. Addressed build system reliability and improved memory safety in PPP network interface initialization. The work demonstrated expertise in embedded systems, low-level programming, and network protocols, resulting in more flexible, maintainable, and robust network and hardware management capabilities.

May 1, 2026May 2026 performance summary: Focused on stabilizing low-level ARM interrupt handling and hardening PPP network interface initialization in levizh/rt-thread. Implemented BASEPRI-based interrupt masking with independent interrupt management across contexts, and fixed potential name contamination in PPP netif by enforcing interface name length constraints and replacing unsafe strncpy with rt_strncpy. These changes improve system determinism, cross-context safety, and network reliability on Cortex-M33 platforms, while enhancing code safety and maintainability.
