Mulugeta Mesfin developed and maintained core features for the cmu-argus-2/FSW-mainboard repository, focusing on reliable image transfer and robust code quality. He implemented a UART-based image transfer protocol with CRC verification, enabling secure payload data handling between embedded systems. Using Python and YAML, Mulugeta integrated in-memory and on-disk storage strategies, enhanced handshake robustness, and improved error handling to reduce field failures. He established CI/CD pipelines with automated linting and unit testing, refactored code for maintainability, and managed simulation data integrity. His work addressed both backend development and DevOps, resulting in a more reliable, testable, and maintainable software foundation.

Nov 1, 2025Month: 2025-11. Focused on improving reliability and data integrity of image transfer on the cmu-argus-2/FSW-mainboard by delivering a robust transfer protocol and stabilizing CRC checks. This work reduces field failures, accelerates troubleshooting, and provides groundwork for on-board storage integration. Overview: Implemented enhancements to the image transfer workflow, with stronger handshake robustness, improved packet handling and data chunk management, and utilities to support robust image transfer. Simultaneously addressed CRC calculation and verification to ensure payload integrity and removed unnecessary debugging prints to streamline processing. The combined work raises the reliability of image transfer in operational environments and positions the project for on-board storage integration. Impact: Higher reliability and data integrity in image transfer, reduced debugging overhead, and a clear path toward on-board storage capabilities.
