Worked on enhancing CPLD update safety and usability for x4xx devices within the pervices/uhd repository by delivering comprehensive documentation improvements. Focused on Doxygen-based documentation, the work clarified update command usage and provided detailed instructions for RPD file copying to ensure users select the correct file for each device. Explicit cautions about potential device bricking were added, along with direct links to support resources, reducing the risk of deployment errors. The changes introduced commit-level traceability, supporting better maintenance and user guidance. This documentation-focused effort aimed to improve deployment reliability and lower the support burden for hardware updates.
