PROFILE
Afnan Alam
Over a three-month period, contributed to the uw-midsun/fwxvi repository by developing four embedded firmware features focused on reliability and hardware integration. Delivered an OTA resilience mechanism with bootloader jump and FOTA timeout handling, refactoring linker scripts and main loop logic in C to improve device recovery and memory safety. Built an I2C API for x86 simulation and a Light Signal Manager using modular architecture and unit testing to enhance signal control and test coverage. Additionally, implemented a Button LED Manager for steering wheel RGB LEDs, leveraging DMA, PWM, and real-time systems concepts to enable robust, customizable driver feedback and diagnostics.

Sep 1, 2025September 2025 (uw-midsun/fwxvi) — Delivered a Button LED Manager for steering wheel RGB LEDs, enabling robust control of SK6812 LEDs via DMA and timer with initialization, color setting, and update functionality. Expanded LED support across steering buttons and integrated the manager into the main steering subsystem. This work enhances driver feedback, diagnostics, and customization readiness, setting the stage for broader UI customization and faster iteration.

Jul 1, 2025July 2025: Delivered two primary features in uw-midsun/fwxvi with significant business value: (1) I2C API for x86 platform with initialization, read, write, and register operations, including buffer management for transmit/receive and x86 simulation support, plus updated smoke tests; (2) Light Signal Manager for turn signals and hazard lights with a defined state machine, initialization, state change requests, state updates, and current state retrieval, accompanied by comprehensive unit tests. Major bugs fixed: none reported this period. Overall impact includes enabling robust x86 I2C integration and reliable signal control, improved test coverage, and stronger maintainability. Technologies/skills demonstrated include API design, embedded systems concepts, simulation, state machines, modular architecture, and test automation.

Jun 1, 2025June 2025 — uw-midsun/fwxvi: Delivered a robust OTA resilience feature and supporting refactors to improve reliability and maintainability. Implemented Bootloader Jump to Application with FOTA Timeout Handling, enabling the bootloader to jump to the application on OTA timeout and prevent device bricking. Performed linker-script refactors to align bootloader and application memory regions, added dedicated headers for jump handling and timeout management, and updated the main loop to trigger an app jump when FOTA timeout occurs. Network read/transmit logic updated to use new static variables to improve stability during OTA. Commit: fb8972d5073b476555028cd768ca26018add9bfe (Afnan Alam BootLoader Jump App and Timeout #65).
