Developing Audio Products with Cortex-M3, NuttX, and C++11

Explore the development of audio products using Cortex-M3, NuttX, and C++11 in this conference talk by Masayuki Ishikawa from Sony. Gain insights into Sony's decision to use NuttX instead of Linux for their embedded projects, considering factors such as development efficiency, code reusability, and feature enhancements. Learn about the modifications made to NuttX, including porting it to ON Semiconductor's LC823450, implementing fast ELF loading, adding minimum adb protocols, and incorporating DVFS in autonomous mode. Discover how middleware and applications were developed using C++11 with LLVM's libc++, and how debugging was facilitated through NuttX support for OpenOCD. Understand the tradeoffs involved in using a non-Linux OS for embedded projects and evaluate whether it's appropriate for your own development needs.
