ALTERANiosII examples work on MicrotronixCyclone ?

Then, I also tried the same steps but using the "low_cost" hello_world example (also for Cyclone),

but got different error message below. Is the USB JTAG cable really needed for NIOSII kit rather than

the old ByteBlasterMV [LPT1] ? are both error messages (here and from my previous post) caused

by this same USB cable or separate issue? Thanks

nios2-terminal: Warning: The JTAG cable you are using is not supported for Nios

nios2-terminal: II systems. You may experience intermittent JTAG communication

nios2-terminal: failures with this cable. Please use a USB Blaster revision B

nios2-terminal: cable or another supported cable. Please refer to the file

nios2-terminal: errata.txt included in the Nios II development kit documents

nios2-terminal: directory for more information.

nios2-terminal: connected to hardware target using JTAG UART on cable

nios2-terminal: "ByteBlasterMV [LPT1]", device 1, instance 0

nios2-terminal: starting in terminal mode only (Control-C exits)

You're first message about the JTAG cable not being supported just means that they are not claiming you're going to get an error proof communication to the FPGA. (they mean you should buy the USB blaster since they'll support it).

And the second message is just a result of the first one I think (I get the message too but I've had no problems, just keep you're cables away from noisy devices like computers/monitors, microwaves, networking equipment, etc..... and you should be fine with that setup.

If you are seeing the printf messenges (Hello world) then everything is working fine

Thanks for the reply,

how about the 1st error message ? (below). It seems to me depending on which example (eg lowcost , standard..) you use, you get a different message; it's very confusing. Can they be all due to the JTAG cable?

# ####error message###

There are no Nios II CPUs with debug modules available which match the values

specified. Please check that your PLD is correctly configured, downloading a

new SOF file if necessary.

Those designs were probably specific to an Altera NIOS kit. That design used flash from that board if I'm not mistaken.

To do you're own first hello world program I recommend starting from scratch (because then you know how do you're own

design). Add you're own design and populate some onchip RAM with the jtag downloader. The code they give you for the

software should be just fine to use.

Or you can just load that hardware design, open the SOPC builder for that design and remove anything that's not on you're

board (like the flash for example).

But I'd recommend starting with something small like a core, RAM, JTAG uart, and debug module then work your way up.

If you do that though expect the code to be huge without making the recommended changes in the IDE (without changes

it'll be around 67kB, and when you put the changes in it will be under 4kB)

Hi,

How can I get the ALtera NIOS II CDROM (eval version) ?

Thank you.

A couple answers...

1. you can download the Nios Ii eval from this forum (look at the download section).

2. The error/message about the cable is to warn you that the cable you are usign MIGHT give some errors.

We found a problem (I'll paste from the errata at the bottom of this post (it's long)).

NOTE: we use byteBlaster MV and II cables for our testing, they may not be the latest and greatest, but we use them constantly. The flash programmer will stress the cable such that you really want to use the revB USB cable, or a modified ByteBlaster (II or MV).

3. I'm not sure about the design problem, but my guess would be that the Microtronix board doesn't have many things that are on the Nios board. The boards would have to have all the things the design requies and the pinoput would need to be the same for the design to work.

Download Cables:

You must use a supported download cable when downloading,

debugging, or communicating with Nios II systems over JTAG.

Using the USB Blaster Rev A, ByteBlaster, ByteBlaster MV,

ByteBlaster II, and MasterBlaster cables may cause intermittent

JTAG communication failures.

The modes of failure are:

* Debugging Failure with the Nios II IDE - Debug session

terminates with JTAG I/O error

* Nios II JTAG UART Failure - Invalid characters transmitted

and received via Nios II Terminal

* Device Configuration Failure - Device configuration fails

with an error message from the Quartus II Programmer

* SignalTap Failure - SignalTap session terminates with JTAG

communication error

If you receive the following message while using the Nios II Terminal,

the tools could not verify whether you are using a supported cable.

nios2-terminal: Warning: Unable to verify whether your download cable is supported for Nios II systems.

nios2-terminal: If you use an unsupported cable, you may experience intermittent JTAG communication failures.

nios2-terminal: Please refer to the file errata.txt included in the Nios II development kit documents directory for

nios2-terminal: information on how to update your system.

In general, the above message will only occur if you have

re-installed Quartus II 4.0 SP1 after you installed Nios II

version 1.0. Re-installing Nios II will allow your system to

detect if your cable is supported. The warning message will

occur each time Nios II Terminal is started until you re-install

Nios II.

If you receive the following message from Nios II Terminal, you

are not using a supported download cable. The warning message will

occur each time Nios II Terminal is started and an unsupported cable

is detected.

nios2-terminal: Warning: The JTAG cable you are using is not supported for Nios II systems.

nios2-terminal: You may experience intermittent JTAG communication failures with this cable.

nios2-terminal: Please use a USB Blaster revision B cable or another supported cable.

nios2-terminal: Please refer to the file errata.txt included in the Nios II development kit documents directory for more information.

The supported cables for downloading, debugging, or communicating

with Nios II systems are:

* USB Blaster Revision B or later

Revision B cables are clearly labeled as Revision B.

(Revision A cables have no revision label.)

* Please contact Altera for additional information

about supported cables.

The Altera Cyclone examples will not work with the Microtronix Cyclone Development Board. The devices on the board are different and the pinout is different.

Hi Kerri,

I could not find the Nios Ii eval software in the download section of this forum.

Thank you

(pinned means it shows up at the top before the different topics).

You need to be registered with Altera to download it (free as well).

I currently use that with the 4.1 Webpack of Quartus on my Stratix 1S10ES device. If you have a full version of quartus then no worries, if not check the compatibility list for the webpack (my device isn't supported by it so I took a version 3 design that was empty and brought it up to 4.1 and it works fine). (So those of you who got stiffed by Parallax with an ES device, this will work)
