Worked on the flipperdevices/u-boot repository, focusing on improving the reliability of the RV3028 real-time clock driver in embedded systems. Addressed a specific bug by ensuring the PORF flag was properly cleared, which is essential for robust timekeeping across different hardware platforms. Utilized C programming and driver development skills to implement the fix, leveraging the dm_i2c_reg_clrset() helper for precise I2C register manipulation. The solution was concise, well-documented, and aligned with the repository’s coding standards, resulting in improved RTC stability and reduced potential for timekeeping failures. All changes were prepared for maintainability and thorough code review.
