NO-OS Overview

NO-OS is a software framework by Analog Devices Inc for systems without OS, otherwise known as baremetal. This framework defines a common interface (API) for accessing typical baremetal peripherals such as GPIO, SPI, I2C, RTC, Timer, Interrupt Controller. This common API may be then used to initialize and control these peripherals in a common way across multiple microcontroller platforms. Currently supported platforms are Intel and Xilinx microprocessors and SoC's as well as Analog Devices' own precision microcontrollers and STMicroelectronics' STM32.

By using this common driver API, the NO-OS is able to provide reference projects for Analog Devices Inc evaluation boards running on various underlying hardware.

NO-OS is an open-source software, and its official repository is NO-OS Github Repository. You are free to use and distribute NO-OS, provided that you comply with the license.

An in-depth article about no-OS internal structure is available at our webpage Understanding and Using the No-OS and Platform Drivers.

Microcontroller no-OS Drivers

The majority of ADI's products are peripherals to a non-ADI digital engine (FPGA, microprocessor, or microcontroller). While there is major work underway on FPGAs (Xilinx and Altera) and microprocessors (running an operating system like Linux), the efforts on microcontrollers are fragmented due to the diverse nature of the microcontroller market. The goal of these projects (microcontroller/no-OS) is to be able to provide reference projects for lower end processors, which can't run Linux or aren't running a specific operating system, to help customers using microcontrollers with ADI parts.

NO-OS Project Build Guide

NOTE: This build guide is valid for the projects found in the no-OS/projects folder. If your project resides elsewhere under the no-OS repository tree, it is a legacy project. A build guide for legacy projects can be found Build no-OS with GNU make.

Clone NO-OS with the --recursive flag: 

git clone --recursive https://github.com/analogdevicesinc/no-OS

If however you've already cloned NO-OS without the --recursive flag, you may initialize all the submodules in an existing NO-OS clone with: 

git submodule update --recursive --init

Build Prerequisites

Prior to building a no-OS project, it is required to set up some environment variables so that the build process may find the necessary tools (compiler, linker, SDK etc.).

Use the following commands to prepare your environment for building no-OS projects:

Linux (Click to expand)

Linux (Click to expand)

Intel (Click to expand)

Intel (Click to expand)

Assuming the SDK is installed at this path: 

/path/to/intel
└── intelFPGA
    └── 18.1

Run: 

$ source no-OS/tools/scripts/platform/intel/environment.sh /path/to/intel/intelFPGA 18.1

Xilinx (Click to expand)

Xilinx (Click to expand)

Assuming the Vitis is installed at this path: 

/path/to/xilinx
├── DocNav
├── Downloads
├── SDK
│   └── 2019.1
└── Vitis
    └── 2021.1

When using no-OS master branch, run: 

$ source /path/to/xilinx/Vitis/2021.1/settings64.sh

When using no-OS 2019_R2 branch, run: 

$ source /path/to/xilinx/SDK/2019.1/settings64.sh

For more information, consult the support/answers/47821.html.

STM32 (Click to expand)

STM32 (Click to expand)

  • Install stm32cubeide to default location /opt/stm32cubeide. If you'd rather install it at a different location, run export STM32CUBEIDE=/path/to/your/stm32cubeide in the terminal used for building.
  • Install stm32cubemx to default location /opt/stm32cubemx. If you'd rather install it at a different location, run export STM32CUBEMX=/path/to/your/stm32cubemx in the terminal used for building.
  • Install java (openjdk-11), sed and head (if not already present, they normally are).

Maxim (Click to expand)

Maxim (Click to expand)

  • Install the Maxim Micros SDK.
  • Set the MAXIM_LIBRARIES environment variable to the MaximSDK/Libraries path (the default should be ~/MaximSDK/Libraries).
  • For visual debugging and building, install Visual Studio Code, and the Cortex-Debug extension.

ADuCM3029 (Click to expand)

ADuCM3029 (Click to expand)

Please install all the necessary packs locally and then manually import them in CrossCore

Common Issues with environment setup:

  • Makefiles searches for the CCES_HOME in its default installation directory. It may happen that multiple version are installed and may not work. To select a CCES_HOME run export CCES_HOME=/opt/analog/cces/2.10.0

Windows (Click to expand)

For more information, consult the Xilinx support support/answers/47821.html.

Note that Xilinx SDK versions 2018.3 or earlier don't properly set up the Windows PATH so that you may use make command provided with the SDK from the shell.

If this is the case, please manually add the following to your Windows PATH or install make for Windows of your choice: 

C:\Xilinx\SDK\2018.3\gnuwin\bin

Maxim (Click to expand)

Maxim (Click to expand)

  • Install the Maxim Micros SDK.
  • Set the MAXIM_LIBRARIES environment variable to the MaximSDK\Libraries path (the default should be C:\MaximSDK\Libraries).
  • For visual debugging and building, install Visual Studio Code, and the Cortex-Debug extension.

ADuCM3029 (Click to expand)

Please install all the necessary packs locally and then manually import them in CrossCore

Common Issues with environment setup:

  • Makefiles searches for the CCES_HOME in its default installation directory. It may happen that multiple version are installed and may not work. To select a CCES_HOME run set CCES_HOME=c:\Analog Devices\CrossCore Embedded Studio 2.10.0
If using PowerShell instead of cmd, open another shell instance after running the above scripts.

# build an ADuCM3029-only project
> make

# if the platform autodetection picks the wrong platform, explicitly specify the PLATFORM
> make PLATFORM=aducm3029

The build process creates a build directory in the project folder: 

build
├── app
├── bsp
├── obj
├── release.elf
└── tmp

Running/Debugging

Once the .elf or .hex file has been generated, make sure the board is powered on, JTAG cable connected and use the following commands to upload the program to the board or debug.

Uploading the binary to target is generically achieved with: 

$ make run

Use the following command to launch the SDK associated to the used platform in order to be able to debug graphically by clicking the debug button: 

$ make sdkopen
