Information for BareMetalArmCortexMSingle

This page provides detailed information about the arm.ovpworld.org BareMetalArmCortexMSingle Virtual Platform / Virtual Prototype.

Description
Bare Metal Platform for an ARM Cortex-M series Processor (default Cortex-M3). The bare metal platform instantiates a single ARM Cortex-M series processor instance. The processor operates using little endian data ordering. It creates contiguous memory from 0x00000000 to 0xFFFFFFFF. The ICM platform can be passed any application compiled to an ARM elf format. It may also be passed a new variant to be used (default Cortex-M3) ./platform.OS.exe --program application.CROSS.elf [ --variant ]

Licensing
Open Source Apache 2.0

Limitations
BareMetal platform for execution of ARM binary files compiled with Linaro 32-bit CrossCompiler toolchain for Cortex-M.

Location
The BareMetalArmCortexMSingle virtual platform is located in an Imperas/OVP installation at the VLNV: arm.ovpworld.org / platform / BareMetalArmCortexMSingle / 1.0.

Command Line Control of the Platform

Built-in Arguments

Table 2: 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.

ARMM Processor Model

Licensing
Usage of binary model under license governing simulator usage.
Note that for models of ARM CPUs the license includes the following terms:
Licensee is granted a non-exclusive, worldwide, non-transferable, revocable licence to:
If no source is being provided to the Licensee: use and copy only (no modifications rights are granted) the model for the sole purpose of designing, developing, analyzing, debugging, testing, verifying, validating and optimizing software which: (a) (i) is for ARM based systems; and (ii) does not incorporate the ARM Models or any part thereof; and (b) such ARM Models may not be used to emulate an ARM based system to run application software in a production or live environment.
If source code is being provided to the Licensee: use, copy and modify the model for the sole purpose of designing, developing, analyzing, debugging, testing, verifying, validating and optimizing software which: (a) (i) is for ARM based systems; and (ii) does not incorporate the ARM Models or any part thereof; and (b) such ARM Models may not be used to emulate an ARM based system to run application software in a production or live environment.
In the case of any Licensee who is either or both an academic or educational institution the purposes shall be limited to internal use.
Except to the extent that such activity is permitted by applicable law, Licensee shall not reverse engineer, decompile, or disassemble this model. If this model was provided to Licensee in Europe, Licensee shall not reverse engineer, decompile or disassemble the Model for the purposes of error correction.
The License agreement does not entitle Licensee to manufacture in silicon any product based on this model.
The License agreement does not entitle Licensee to use this model for evaluating the validity of any ARM patent.
The License agreement does not entitle Licensee to use the model to emulate an ARM based system to run application software in a production or live environment.
Source of model available under separate Imperas Software License Agreement.

Limitations
Performance Monitors are not implemented.
Debug Extension and related blocks are not implemented.

Verification
Models have been extensively tested by Imperas. ARM Cortex-M models have been successfully used by customers to simulate the Micrium uC/OS-II kernel and FreeRTOS.

Features
The model is configured with 16 interrupts and 3 priority bits (use override_numInterrupts and override_priorityBits parameters to change these).
Thumb-2 instructions are supported.
MPU is present. Use parameter override_MPU_TYPE to disable it or change the number of MPU regions if required.
SysTick timer is present. Use parameter SysTickPresent to disable it if required.
FPU extension is not present. Use parameter override_MVFR0 to enable it if required.
DSP extension is not present. Use parameter override_InstructionAttributes3 to enable it if required.
Bit-band region is present. Use parameter BitBandPresent to disable it if required.

Instance Parameters
Several parameters can be specified when a processor is instanced in a platform. For this processor instance 'cpu1' it has been instanced with the following parameters:
