Information for ArmCortexMuCOS-II
This page provides detailed information about the imperas.ovpworld.org ArmCortexMuCOS-II Virtual Platform / Virtual Prototype.
Platform for Micrium uc/OS-II bring up and simple LED access
Open Source Apache 2.0
BareMetal platform for bring up of uc/OS-II on ARM Cortex-M3 processor
The ArmCortexMuCOS-II virtual platform is located in an Imperas/OVP installation at the VLNV: imperas.ovpworld.org / module / ArmCortexMuCOS-II / 1.0.

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.
Performance Monitors are not implemented.
Debug Extension and related blocks are not implemented.
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.
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.
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:
Table 4: Processor Instance 'cpu1' Parameters (Configurations)
|endian||little||Select processor endian (big or little)|
|simulateexceptions||simulateexceptions||Causes the processor simulate exceptions instead of halting|
|mips||100.0||The nominal MIPS for the processor|
|imagefile||ucosiiDemoApplication.ARM_CORTEX_M3.elf||The image file to load onto the processor|
|semihostvendor||arm.ovpworld.org||The VLNV vendor name of a Semihost library|
|semihostname||armNewlib||The VLNV name of a Semihost library|
