NuttX for Embedded Linux Developers

Explore NuttX, an open-source POSIX-compliant RTOS suitable for resource-constrained devices and real-time systems, in this informative conference talk. Discover how Sony utilizes NuttX in shipped audio products and research for future developments, including SMP systems and networking capabilities. Learn about the portability of Linux applications to NuttX, exemplified by the successful porting of the Alexa/AVS device SDK to a Cortex-M3 board. Gain insights into NuttX implementation on Sony's Spresense board and the ongoing efforts to upstream this work. Understand the advantages of developing and testing application code on Linux before deploying to NuttX, a useful approach for targeting systems where Linux usage is impractical. The talk also covers the first NuttX international workshop outcomes and provides information about an upcoming NuttX meetup.
