In this session, we will explore the audio stack and frameworks available in Zephyr, with a particular focus on Sound Open Firmware (SOF) - an open-source audio digital signal processing (DSP) firmware and SDK that provides essential infrastructure and tools for audio and signal processing development.
With the release of SOF 2.0, the project has integrated Zephyr RTOS, simplifying and improving its codebase. However, SOF remains tightly coupled to a Linux host OS driver, making it primarily suited for MPUs.
This talk will dive into decoupling SOF from Linux to enable standalone operation on MCUs, making it the go-to audio framework for Zephyr.
Key topics will include:
• Replacing Linux-based host communication
• Modifying SOF firmware to run without Linux-driven configuration
• Leveraging Zephyr drivers for hardware control
Join us to discuss the next steps in making SOF a truly Zephyr-native audio framework.
