OVP Virtual Platform: BareMetalPowerPc32Single

What is a Bare Metal Platform?

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

Bare Metal Platform

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

Obtaining the BareMetalPowerPc32Single platform and the OVP Simulator

The source and binary of the bare metal platforms are part of the OVP/Imperas downloads and live on a VLNV (Vendor Library Name Version) path.

To download from OVPworld, browse the OVP downloads page and download the OVPsim package. Click here to browse available downloads.

When installed this platform is found in your installation here: ImperasLib/source/power.ovpworld.org/platform/BareMetalPowerPc32Single/1.0.

Running the Bare Metal Platform

1. 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.

2. Enter the Demo Directory IMPERAS_HOME/Demo/BareMetalPowerPc32Single

3. On Windows, double-click on the batch file xx.bat and on Linux run the script xx.sh to run a simple application elf file on the Bare Metal Platform.

You will see output something like:
Info (ARM_NEWLIB_RDI_HEAP_INFO) RDI heap_base=0xc0000000 
Hello
Info (ARM_NEWLIB_RDI_EXIT) Process has ended (exit)

Setting Up for Re-building the Application

To rebuild the application and create the elf file you will need 3 things:
  • Cross-Compiler toolchain for thi processor
  • An OVP Installation
  • MSYS / MINGW environment (Windows Users Only)

Download and Installing the Cross-Compiler Toolchain

To download an appropriate tool chain, browse the OVP downloads page and download the package. Click here to browse.
If there is not one available please ask on the forum.

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

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 Demo/'baremetaldemodir' directory using an MSYS shell for Windows or a Linux shell.

Re-building the 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:
> ./BareMetal.OS.exe hello.CROSS.elf



This page provides detailed information about the OVP Virtual Platform Model of the power.ovpworld.org BareMetalPowerPc32Single platform.

Description

Bare Metal Platform for an PowerPc32 Processor. The bare metal platform instantiates a single PowerPc32 processor instance. The processor operates using big and little endian data ordering. It creates contiguous memory from 0x00000000 to 0xFFFFFFFF. The platform can be passed any application compiled to an PowerPc32 elf format. ./platform.exe --program application.elf

Licensing

Open Source Apache 2.0

Limitations

BareMetal platform for execution of PowerPc32 binary files.

Reference

None, baremetal platform definition

Location

The BareMetalPowerPc32Single virtual platform is located in an Imperas/OVP installation at the VLNV: power.ovpworld.org / platform / BareMetalPowerPc32Single / 1.0.

Command Line Control of the Platform

Built-in Arguments

Table 1: Platform Built-in Arguments

AttributeValueDescription
allargsallargsThe Command line parser will accept the complete imperas argument set. Note that this option is ignored in some Imperas products

When running a platform in a Windows or Linux shell several command arguments can be specified. Typically there is a '-help' command which lists the commands available in the platforms.
For example: myplatform.exe -help

Some command line arguments require a value to be provided.
For example: myplatform.exe -program myimagefile.elf

Platform Specific Command Line Arguments

No platform specific command line arguments have been specified.
