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). ...

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 ...

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....

I am working on an IP core with a Nios controller. This IP will eventually be integrated into a multi-Nios system. I also foresee that this IP will not be JTAG debuggable because the integrator will be using the JTAG facility on a higher level Nios controller. In this case I have planned to include a UART interface, which allows the integrator to do on-the-fly primitive debugging with t...

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 ...

I have an SRAM controller Avalon slave we created which Nios can successfully access to read and write SRAM.

Let's say I have GERMS on-chip in M4Ks, I have an on-chip MegaRAM slave, and an SRAM control...

My first problem is to assemble these files. Has an...
