In January 2026, Yanny contributed to the DragonBluep/openwrt repository by adding support for the TP-Link EAP620HD v3 access point. Yanny developed device tree specifications, wrote installation instructions, and integrated the device into the OpenWrt firmware build system, focusing on reproducibility and maintainability. The work involved updating IPQ60xx target configurations and ensuring seamless hardware compatibility for enterprise deployments. Using C and Makefile, along with expertise in Linux kernel and embedded systems, Yanny addressed the need for broader device support without introducing new bugs. The contribution demonstrated depth in firmware development and careful attention to integration and documentation within the project.
