PROFILE

Viorel Suman

Contributed to the flipperdevices/u-boot repository by implementing interrupt-driven SCMI communication support for the i.MX95 System Manager, enhancing real-time system integration and responsiveness. This work involved configuring the SCMI shared memory header flag to enable interrupt-driven operation, reducing latency and improving embedded workflow performance. Additionally, addressed a critical flash memory reliability issue by aligning erase and write operations to erase block boundaries, mirroring existing read alignment to prevent data corruption. Demonstrated expertise in embedded systems, firmware development, and memory management using C, with a focus on low-level hardware integration and robust, traceable changes that improve system maintainability and reliability.
