Marian Cingel worked on the flipperdevices/u-boot repository, focusing on improving hardware reliability for TI-based boards by addressing I2C communication issues with the CAT24C256WI-GT3 EEPROM. Using C programming and embedded systems expertise, Marian introduced a 5ms delay between write and read operations to satisfy EEPROM timing requirements, effectively resolving NACK errors and intermittent failures during boot-time EEPROM access. The solution enhanced initialization stability and maintainability, with clear inline documentation and a signed-off patch for future traceability. Marian’s work demonstrated a careful approach to low-level hardware timing and I2C protocol nuances, resulting in more robust board initialization routines.
