Developed and integrated audio topology and ADSP firmware support for the qcs6490-radxa-dragon-q6a platform within the NVIDIA/linux-firmware repository, delivering platform-ready audio functionality. The work involved creating new binary firmware and JSON configuration files to enable end-to-end audio routing and processing across ADSP domains, ensuring the hardware was fully supported for audio use cases. Leveraging expertise in audio driver development, embedded systems, and firmware development, the implementation provided a configurable and robust solution tailored for the target platform. The resulting firmware package was delivered ready for QA validation and field deployment, supporting hardware enablement and future scalability needs.
