Xilinx Linux is the most prevalent operating system used by Xilinx products. Xilinx provides the PetaLinux tools for a simplified Linux development flow, as well as source code and Yocto recipe files from our GIT repository such that Linux support for Xilinx silicon can be supported by in-house build systems or 3rd party tools. The Xilinx Linux project is a customized non-commercial Linux development project catered towards development on Versal™ ACAP, Zynq® SoC and MicroBlaze™.
The Linux kernel support for the Xilinx releases are:
The new Vitis™ unified software platform, Xilinx Software Development Kit (SDK), and Ecosystem Partner tools offer a wide choice of development environments that enable SoC-like C/C++ programming of the Zynq and MPSoC platforms.

Xilinx offers two tools to build and deploy Emebdded Linux solutions. These are Xilinx’s PetaLinux and the Open Source Project of Yocto. PetaLinux offers the user a GUI to quickly build the Embedded Linux and Yocto can be used by more experienced users to custom based Linux for their boards.
Xilinx products are supported by comprehensive set of open source resources to develop, boot, run, debug and maintain your Linux based application for a Xilinx SoC or emulation platform. We offer example applications, Kernel configurations, Yocto recipes, Multiprocessing and Real-time solutions, device drivers and Linux open source developer will find familiar sources, tools, and support forums to learn, develop and interact with others of like interests, needs and passion.
"A real-time operating system (RTOS) is an operating system (OS) intended to serve real-time application process data as it comes in, typically without buffering delays. (wikipedia.org)”
Key factors in an RTOS are keeping it simple and light weight. Other factors are minimal interrupt latency and contact thread switching latency. An RTOS is valued more for how quickly and how deterministically it can respond than for the amount of complexity it can handle.
The FreeRTOS kernel was originally developed by Richard Barry around 2003, and was later developed and maintained by Richard's company, Real Time Engineers Ltd.
FreeRTOS was a runaway success, and in 2017 Real Time Engineers Ltd. passed stewardship of the FreeRTOS project to Amazon Web Services (AWS). Richard continues to work on FreeRTOS as part of an AWS team.
FreeRTOS™ is a market leading RTOS from Amazon Web Services that supports more than 35 architectures and was downloaded once every 3 minutes during 2017. It is professionally developed, strictly quality controlled, robust, supported, and free to embed in commercial products without any requirement to expose your proprietary source code.(reference: https://www.freertos.org/RTOS.html)

The Cortex-M1 and Cortex-M3 processors are 32-bit processors designed for low power, low logic resources and low interrupt latency performance. The Cortex-M1 is designed very much for constrained applications, which require communication, control and management. While the M3 is intended for a wide range of embedded and IoT applications. To support forward compatibility the Cortex-M1 implements a subset of the Cortex-M3 instruction set and features.

Xilinx has been using Open Source Linux since it has introduced processors in their devices. The first was the Virtex-II Pro in 2001. Since that time Xilinx has utilized Open Source Linux and started to contribute with upstream patches since 2007. When Xilinx unveiled Zynq™-7000 they started to really establish themselves in the Linux community. They now are one of the leading contributors to the Linux Uboot project.
Linaro is an open source project that developments software across the entire Arm Ecosystem. Linaro partners with ARM to co-maintain the Arm Ecosystem.
As stated on the 96boards page “96Boards is a range of hardware specifications created by Linaro to make the latest ARM-based processors available to developers at a reasonable cost. The specifications are open and define a standard board layout for SoC-agnostic (processor independent) development platforms that can be used by software application, hardware device, kernel and other system software developers.”
The 96Board with a Xilinx device is an Ultra96 that is sold by Avnet. There is development by Avnet, Xilinx and the Linaro community on the Ultra96. For more information visit http://zedboard.org/product/ultra96-v2-development-board
OpenAMP is a Linaro Community Project that seeks to standardize the interactions between operating environments in a heterogeneous embedded system through open source solutions. The OpenAMP Initative include the following items
As the Yocto Project states: “The Yocto Project is an open source collaboration project that helps developers create custom Linux-based systems for embedded products, regardless of the hardware architecture. The project provides a flexible set of tools and a space where embedded developers worldwide can share technologies, software stacks, configurations and best practices which can be used to create tailored Linux images for embedded devices.”
