NIOS II multi core system

[Altera_Forum]

hi i am using cyclone II EP2C35F6726C6, i have try to create dual core system but unable to download .elf file. so can you suggest NIOS II IDE software building step

I would like to do the same on Arria and Stratix ... where each NIOS has its own IMEM for code and stack/heap ... did you get any answers Sachin ?

You need to think about: 

- how to get the code loaded for the final system - ie when not using JTAG. - whether the two nios are completely independant, or whether they work as a pair. - whether you are going to compile the code separately, or as a single object (might be difficult if you use the Altera build scripts).  You almost certainly need to expose the 'soft reset' signals - maybe so that the second nios is held in reset until the first has finished its initialisation and loaded the code for both from EPCS.

Ok thanks DSL 

  "how to get the code loaded for the final system - ie when not using JTAG." The first issue I have is loading code into the independent NIOS II's via the ECLIPSE ... I guess I can easily duplicate the one NIOS II and see if the  ECLIPSE environment understands that there are two "hello_world" .elf's that are to be loaded into separate NIOS II's ... if I could do that then I  could test each NOIS II at a time then try them both running together .   "whether the two nios are completely independant, or whether they work as a pair" I would like them to be completely independent... where the Avalon MM fabric handles arbitration to shared Avalon MM slaves.   "- whether you are going to compile the code separately, or as a single object (might be difficult if you use the Altera build scripts)." I would like to be able to compile code separately as two .elf's that could be loaded into separate IMEM instantiated for each NIOS II.  I am looking for a pointer to an example by Altera or a thread here where it has been done before.  Thanks, Bob.

Have you read through this older document? http://www.altera.com/literature/tt/tt_nios2_multiprocessor_tutorial.pdf
