Enabling Sound Open Firmware on Arm Cortex-A Based Devices Using Zephyr RTOS

Explore the process of enabling Sound Open Firmware on Arm® Cortex®-A based devices using Zephyr RTOS in this 33-minute conference talk by Daniel Baluta from NXP. Learn about the open-source audio DSP firmware's modular and generic codebase, originally developed for Cadence® Tensilica® HiFi 4 DSP, and its potential for porting to different architectures. Discover how to implement this firmware on newer Cortex-A devices without a separate DSP by utilizing the Jailhouse hypervisor to reserve an Arm Cortex-A core for running Sound Open Firmware as a Zephyr RTOS application. Gain insights into the general solution of running Linux OS and Zephyr RTOS on separate ARM® Cortex-A cores using Jailhouse hypervisor. Delve into the specific process of enabling Zephyr on a Cortex-A55 core and integrating Sound Open Firmware applications, expanding your knowledge of embedded systems and audio processing capabilities.
