Hi, I would like to simulate a NIOS system with modelsim but I have very strange results : it seems that the external SRAM (for the Nios Apex dev board) is incorectly adressed by the NIOS processor. I'm using quartus 2.2 and sopc builder 2.8 (NIOS 3.0) Here is what I'm doing : - the system is minimal (a 32 bit nios, an UART, an on chip memory, the external SRAM and two user interfaces). ...

Hi, I'm having problems getting nios-run -t to function correctly. The development platform is Quartus 3 sp2, SOPC 3.02 on Linux, Apex board. I'm using the standard_32 example provided with the Nios kit 3.2. This builds (SDK and the hardware) without apparent problem, synthesises and can be downloaded via the jtag interface. executing nios-run -t results in the peripherals test menu bei...

I have downloaded the quartusIIwe, and used it to synthesize some modules for cyclone parts - works great. Now I would like to try SOPC builder and compile some C for an existing nios board, but am a little confused about the toolchain. QuartusII comes with cygwin, but it looks like there is no gcc, etc. for nios. Altera's site says the Gnupro tools for nios do not require a license, ...

Hi, Awhile back I tried having Nios II and a separate cygwin (from cygwin.com) on the same machine, but ran into big problems. I now want to install the latest Nios II eval kit but I'm not sure if Altera has fixed things so they can co-exist. Does anyone have a stand-alone Cygwin and Nios II tools running fine on the same machine? I thought I'd ask beforehand because I sure don't want t...

Hi, Has anybody been trying to use gprof within the NIOS II IDE ? We have some problems regarding the profiling data that is send through the jtag interface directly to the IDE console window. We had a look to the documentation but there is little information regarding the use of the profiler with the NIOS II. It seems that, to the difference of NIOS I, the profiling data is sent as ...

Tomorrow is the big Nios II launch date, but info is already going up.... www.altera.com http://www.fpgajournal.com/articles/20040518_nios2.htm Full 32bit. 2X-4X faster than Nios I and starts at only 500 LE's. New IDE. New Compact Flash and other periferals.... Can't wait to get a hold of it. Ken

Hello, I have also posted this message on the niosforums site. Hopefully someone here will have an insight to my problem. I am developing on a system that is very similar to the Nios II evaluation kit. I am trying to transfer data to and from the LAN91C111 Ethernet MAC but have noticed some problems. The MAC is connected to the Nios II in exactly the same way as on the demo board. It ...

Altera Nios II & PCI Compiler 4.1.0 Question

Hi, I'm using SOPC Builder and added some components, including NIOS II, external RAM and a PCI Host-Bridge (PCI Compiler 4.1.0). Is there, by coincidence, a reference design available of a system using Nios II and the PCI Compiler together? I know there is a reference design in the PCI Compiler User Guide, but it doesn't use the Nios II processor, which I really need in my design. Anot...

Hi, Has anyone got NIOS software to boot from Flash? I'm working on a Stratix II-based design with onboard NIOS and peripherals (16MB flash, Ethernet, SDRAM etc). The Flash, Ethernet, and SDRAM components are wired to the Stratix-II via an Avalon tri-state bus, similar to the design on the Stratix Edition Nios development kit. A single Nios CPU core is running at 50MHz.on the Stratix II....

Hello. I'm getting a better outline of what's available and the differences between the different options, such as FPGAs and CPLDs. Although, I've just come across Alteras "Nios II Embedded Processor" and to be honest it's thrown me off completely. - What is a soft-core processor? - It seems that Nios II isn't a physical product I buy, it appears to be an emulator running on top of any ...

Hi, I am new to Altera Eclipse for quartus subscription 9.1 version. I want to learn NIOS programming. I go through the simpliest version on 'Getting Started' part in "Nios II Software Developer's Handbook". I create a project step by step according to the handbook (I have no NIOS II evaluation board at home). The project is created with 'Nios II Application and BSP from Template' option. ...

Hi All, is there any chance to run Nios II Multiprocessor Collection in command line? I have the system with 2 cpus. I've tried to run the programs separately, but in that case mutex doesn't work properly. Perhaps smth wrong with cpu's ID value. Note: from Nios II IDE it works fine, when I use Nios II Multiprocessor Collection. Best regards, Ewa.

I'm trying to simulate a NIOS based system with a altera_avalon_new_sdram_controller which is shared with the systembus. When I try to do a write (ST) to the SDRAM I see that the cpu.the_sdram_s1.sdram_s1_chipselect is asserted. However the NIOS top level cpu.zs_cs_n_to_the_sdram_sdram_chip is not. If I replace the SDRAM target address of the ST instruction with a different different t...
Nios & off-chip memory

Hi, I'm using a Nios to access off-chip memories via the SoPC-builer's external memory bridge. The Nios is 32-bit data, the memories are 16-bit data. Using SignalTap I can see that Nios is only accessing even addresses in the external memory (using germs monitor commands and/or my own c-code). Has anyone there come across something like this before? Thanks in advance, Alan Myler
