Worked on enhancing the RS485 documentation within the phytec/doc-bsp-yocto repository by replacing a hardcoded RS485 identifier with a generic serial-uart device reference. This update improved the flexibility and portability of documentation examples, allowing them to be reused across different hardware configurations and Yocto environments. The approach focused on hardware abstraction and reduced environment-specific constraints, aligning documentation with the |serial-uart| configuration method. Utilized RST for documentation and applied best practices in embedded systems and version control with Git. No bugs were fixed during this period, with efforts concentrated on documentation consistency and enabling easier cross-platform validation and testing.
