Worked on reliability hardening of the I2C subsystem in the flipperdevices/u-boot repository, focusing on improving error handling within embedded systems. Addressed a specific issue in the I2C driver by implementing standardized timeout error signaling, ensuring that timeout conditions now return -ETIMEDOUT instead of a generic value. This change aligned the driver’s behavior with u-boot conventions, enhancing diagnosability and supporting more robust error management in downstream boot workflows. Utilized C and applied expertise in driver development and the I2C protocol to deliver a targeted bug fix, improving the reliability and monitoring readiness of the boot process without introducing new features.
