Worked on enhancing the flipperdevices/u-boot repository by implementing Virtio I/O size and segment limit handling using C programming and low-level device driver development skills. Developed logic to split large I/O requests into multiple virtio calls, ensuring that operations respect SIZE_MAX and SEG_MAX hardware constraints. This approach improved system reliability during boot and device initialization by reducing the risk of I/O failures across diverse hardware configurations. The solution increased cross-device compatibility and resilience, contributing to overall system stability. All changes were fully documented and committed with traceability in mind, supporting maintainability and ongoing development within the u-boot codebase.
