Information for BareMetalNios_IISingle
This page provides detailed information about the altera.ovpworld.org BareMetalNios_IISingle Virtual Platform / Virtual Prototype.
Description
Bare Metal Platform for an Nios_II Processor.
The bare metal platform instantiates a single Nios_II processor instance.
The processor operate using big endian data ordering.
It creates contiguous memory from 0x00000000 to 0xFFFFFFFF.
The platform can be passed any application compiled to an Nios_II elf format.
./platform.exe application.elf
Licensing
Open Source Apache 2.0
Limitations
BareMetal platform for execution of Nios_II binary files compiled with CodeSourcery CrossCompiler toolchain.
Reference
None, baremetal platform definition
Location
The BareMetalNios_IISingle virtual platform is located in an Imperas/OVP installation at the VLNV: altera.ovpworld.org / platform / BareMetalNios_IISingle / 1.0.
