Information for BareMetalM14KSingle
This page provides detailed information about the mips.ovpworld.org BareMetalM14KSingle Virtual Platform / Virtual Prototype. Table 1: Components in platform
Description
Bare Metal Platform for a MIPS M14K Processor.
The bare metal platform instantiates a single M14K processor instance, using big endian data ordering.
The platform can be passed any application compiled to a MIPS elf format as the argument
It will also allow a port number to be specified to allow the connection of a remote GDB debugger.
platform.OS.exe -program application.CROSS.elf [-port
Licensing
Open Source Apache 2.0
Limitations
BareMetal platform for execution of MIPS M14K binary files compiled with CodeSourcery CrossCompiler toolchain.
Location
The BareMetalM14KSingle virtual platform is located in an Imperas/OVP installation at the VLNV: mips.ovpworld.org / platform / BareMetalM14KSingle / 1.0.
