Demos targeting RISC-V

  • RISC-V Spike Simulator GCC
    [Unofficial third party demo, links to the FreeRTOS Interactive site]
    The port automatically configures itself for 32-bit and 64-bit RISC-V architectures on basis of #defines set by GCC. The demo application runs on the spike simulator in 64-bit mode, and needs the riscv GCC compiler and spike simulator to be installed somewhere for the build to succeed.


Demos targeting Silicon Labs products

The FreeRTOS ARM Cortex-M ports will run on all Silicon Labs ARM Cortex-M microcontrollers. See the Creating a new application and Adapting a Demo pages.


Demos targeting Spansion products

These demos can be adapted to any microcontroller within the same family that has sufficient ROM/RAM. See the Creating a new application and Adapting a Demo pages.


Demos targeting ST Microelectronics products

These demos can be adapted to any microcontroller within the same family that has sufficient ROM/RAM. See the Creating a new application and Adapting a Demo pages.


Demos targeting Synopsys DesignWare ARC Products

The FreeRTOS download does not contain official ARC support, but the following options are available to users wishing to run the RTOS on DesignWare ARC microcontrollers:
  • The embARC Open Software Platform consists of software and documentation to accelerate the development of embedded and IoT systems based on DesignWare ARC processors.

  • Our official partner company, WITTENSTEIN high integrity systems, can provide OpenRTOS for various ARC processors.

Demos targeting Intel IA32 and any x86 products

  • IA32 / Intel Quark SoC X1000 in 32-bit mode
    The demo presented on this page used GCC and Eclipse to run FreeRTOS on an Intel Galileo single board computer.

  • Industrial PC Single Board Computer
    This will run on a huge variety of PC/AT compatible industrial and single board computers, including PC/104 systems. It can use the Open Watcom or Borland development tools, for both of which a pre-configured project file is provided. See the Tools page.

  • RDC8822 Based Single Board Computer
    This runs on the very competitively priced Flashlite 186 single board computer from JK Microsystems. The RDC8822 is an AMD embedded 186 clone (AM186ED). It can use the Open Watcom or Borland development tools (see Tools). Again a pre-configured project file is provided for both compilers.

  • RDC R1120 Based Single Board Computer
    Includes a simple web server demo running on a Tern E-Engine controller using a memory mapped WizNET TCP/IP co-processor. The RDC1120 is an AMD embedded 186 clone (AM186ES). The demo application builds with the Paradigm C/C++ compiler and can be remotely debugged from within the compiler IDE.


Demos targeting Windows (simulator)

  • Windows Simulator for Visual Studio Express and Eclipse with MingW (GCC)
    This allows FreeRTOS to be run in a Windows environment - although true real time behaviour cannot be achieved. Demo projects are provided for both Eclipse with MingW (GCC) and Visual Studio 2010 Express Edition. Both these tool chains are free, although Visual Studio Express requires registration if it is to be used for anything other than evaluation purposes. The principal of the simulated operation is described on the demos documentation page.
