ARC Bare Metal Platform

What is a bare Metal Platform?

A "Bare Metal" Platform consists of a single processor with memory available over its complete address range.

This is ideal for execution of a user application that has been compiled for the target processor core using cross-compilation.

Obtaining the ARC Bare Metal Platform

DOWNLOAD ARC Bare Metal Platform installer for Windows 32-bit host
BareMetalArc.Windows32.exe / 1.54 MB

DOWNLOAD ARC Bare Metal Platform installer for Linux 32-bit host
BareMetalArc.Linux32.exe / 1.71 MB

Running the Bare Metal Platform

Run the installer to install into a local directory on your PC. We recommend you use a path without spaces, for example your home directory.
Enter the Demo Directory <IMPERAS_HOME>/Demo/BareMetalArc
On Windows, double-click on the batch file hello.bat and on Linux run the script hello.sh to run a simple 'Hello World' application on the PowerPc32 Bare Metal Platform

You will see output that includes:

Setting Up for Re-building the ARC Application

To rebuild the ARC application and platform you will need the

ARC Cross-Compiler toolchain
An OVP installation
MSYS / MINGW environment (Windows Users Only)

Obtaining OVP

[for Windows] Main OVP Download including OVPsim Simulator (49.78 MB)
Binary of the simulator, headers, examples of creating processors, peripherals and platforms, and running. Includes full documentation. Includes many models as source code.

[for Linux] Main OVP Download including OVPsim Simulator (57.7 MB)
Binary of the simulator, headers, examples of creating processors, peripherals and platforms, and running. Includes full documentation. Includes many models as source code.

Once downloaded run the installer *.Windows32.exe for Windows and *.Linux32.exe for Linux to install on your PC.

Download and Installing ARC Cross-Compiler Toolchain

As part of the OVPsim installation default Makefiles are supplied to allow applications to be built using the Codito toolchains for ARC for the ARC600 and ARC700 family processors.
WARNING: The toolchain from Codito is no longer available.

There are no Makefiles currently compatible with free GNU toolchains that are available. We will add new Makefiles in the future that will support other Cross Compilers for ARC, such as that provided at

http://sourceforge.net/projects/arc-linux/files/ARC%20GNU%20Toolchain/∞

In the meantime, please download available Cross Compiler toolchains and follow the instructions provided to compile and link code for the ARC600 and ARC700 processors.

Installing MSYS / MINGW Environment (Windows Users Only)

Obtaining and installing the MSYS and MINGW environment is described in Imperas_Installation_and_Getting_Started.pdf

Rebuilding

You will need to be in the BareMetalArc directory using an MSYS shell for Windows or a Linux shell.

Re-building the ARC Application

> make application

Re-building the Bare Metal Platform

> make platform

Executing the application on the platform

You can just double click on the .bat file as done previously, or you can run from the msys command line:
> ./BareMetalArc.<OS>.exe hello.<CROSS>.elf
