Over a three-month period, contributed to the flipperdevices/u-boot repository by developing and integrating watchdog functionality across multiple ARM-based platforms. Focused on robust system initialization, the work involved initializing Error Signaling Modules (ESM) and PMIC ESM components to enable reliable watchdog operation and automatic board resets on critical errors. Using embedded C, driver development, and kernel configuration skills, implemented iterative device enumeration with error handling and conditional initialization logic. These enhancements improved system reliability and fault detection for platforms such as j721s2, j722s, and j784s4, aligning with production stability goals and ensuring consistent error recovery without addressing major bug fixes.
