Developed and integrated support for the Teltonika TSW202 PoE switch within the DragonBluep/openwrt repository, focusing on device driver development and embedded systems. The work involved enabling OpenWrt compatibility for the RTL8380M-based switch, configuring eight PoE-capable ports and two SFP slots, and implementing per-port PoE budgeting up to 30W. Installation and flashing procedures were documented, including sysupgrade guidance over SSH, to streamline deployment for enterprise edge environments. Leveraging C and DTS, the implementation addressed hardware configuration and web UI management, expanding OpenWrt’s hardware support and facilitating PoE-enabled networking solutions without addressing major bug fixes during this period.
