Dhanoo Surasarang developed secure DMA attribute support for the Nordic VPR launcher within the zephyrproject-rtos/zephyr-testing repository, focusing on enhancing the security posture of embedded systems. By extending device tree bindings and driver configuration, Dhanoo enabled the VPR coprocessor to enforce secure DMA paths, addressing both integration readiness and business value. The work involved C and YAML, leveraging expertise in driver development and embedded security. The implementation introduced a repeatable build and test process, ensuring robust technical delivery. This feature addressed the need for secure DMA operations in the Nordic VPR environment, reflecting a focused and technically sound engineering approach.
