PROFILE
Ryan Hsu
Contributed to the Wiwynn/OpenBIC repository by developing and validating a direct coredump collection feature, enabling the BMC to retrieve coredump data from QSPI flash via SPI and PLDM without relying on the CXL console. This work involved implementing a PLDM OEM command, updating QSPI multiplexer switching, and integrating a new SPI read path, all in C and C++. Additionally, calibrated the MB_ADC_PVDD18_S5_VOLT_V sensor threshold to improve voltage monitoring accuracy and reduce false alarms. Demonstrated expertise in embedded systems, firmware development, hardware monitoring, and protocol integration, with a focus on robust testing and code review throughout the process.

May 1, 20262026-05 monthly summary for Wiwynn/OpenBIC: Delivered Direct Coredump Collection via SPI and PLDM, enabling reading coredump data directly from QSPI flash via the BMC without requiring the CXL console. Implemented PLDM OEM command 0x08, added a platform SPI read path, and updated QSPI multiplexer switching to support coredump retrieval. PR 2709 merged with code review and differential revision (D103219254); validated end-to-end using pldmtool tests. Impact: faster root-cause analysis, reduced MTTR, and a more robust data path between BMC and BIC. Technologies/skills demonstrated: SPI, PLDM, QSPI, PLDM OEM commands, BMC-WF BIC integration, CXL coredump handling, code review, and CI/test automation.
