Jcyu-accton
Over eight months, Jcyu developed and integrated advanced networking platform features for the facebook/fboss repository, focusing on high-bandwidth Ethernet support and scalable hardware onboarding. Jcyu engineered platform mapping, port profile configuration, and SAI integration for devices like Minipack3N and Wedge800 variants, using C++ and Python to automate CSV-to-JSON data mapping and ensure PRD compliance. Their work included expanding profile ID coverage, refining configuration assets, and maintaining rigorous code quality through automated testing and pre-commit checks. By aligning platform mappings with evolving hardware requirements, Jcyu improved deployment flexibility, test automation, and long-term maintainability across multiple embedded networking platforms.

Oct 1, 2025Oct 2025 FBOSS monthly summary focused on Wedge800 and Wedge800BA platform work. Key outcomes include new Wedge800 copper PAM4 profiles (PROFILE_200G_2_PAM4_RS544_COPPER=54, PROFILE_100G_2_PAM4_RS544_COPPER=55, PROFILE_100G_1_PAM4_RS544_COPPER=56) and PMCG fixes for existing profiles (14, 19, 16, 21, 31, 32, 43) to ensure correct port speed, lane count, and transmitter technology. Also delivered Wedge800BA platform mapping CSVs covering extensive optical and copper front/service ports with profiles such as 39, 38, 25, 23, 47, 50, 45, 24, 22, 32, 54-56, and more, with generation workflow to produce corresponding JSON mappings. This work improves port bring-up, diagnostics, and test automation, reduces misconfigurations, and enables faster hardware validation.
