Getting started with the Zephyr OS
In this recipe, we will install the Zephyr Project, the framework that will allow us to build and run the TensorFlow application on the emulated Arm Cortex-M3 microcontroller. By the end of this recipe, we will have the environment ready on our laptop/PC to run a sample application on the virtual platform considered for our project.
Getting ready
Zephyr (https://zephyrproject.org/) is an open-source Apache 2.0 project that provides a small-footprint Real-Time Operating System (RTOS) for various hardware platforms based on multiple architectures, including Arm Cortex-M, Intel x86, ARC, Nios II, and RISC-V. The RTOS has been designed for memory-constrained devices with security in mind.
Zephyr does not provide just an RTOS, though. It also offers a Software Development Kit (SDK) with a collection of ready-to-use examples and tools to build Zephyr-based applications for a wide range of devices, including virtual platforms through QEMU.
