ISP1362 (USB on DE2) with Quartus 7.2

Question

Hello,

I am a german university student and I started working with Alteras DE2 Board a short time ago. I'm using Quartus II Web Edition 7.2.

Now I'm trying to program the Cyclone II on the DE2 as USB Client. Therefore I downloaded a SOPC builder component for the ISP1362 from http://nioswiki.jot.com/wikihome/operatingsystems/%c2%b5clinux/usbhost

It seems that the SOPC Builder 7.2 doesn't know the signal type "export" so I'm getting warnings during compilation. I wrote a test program in C and it seems that I can't connect to the ISP1362 properly.

What is the appropriate signal form for the connection to the ISP1362? On Quartus II 6.0 I don't get any warning and the "export" signal form is accepted, but I have to work with 7.2 obligatory. May someone tell me how I can design a 1362 component by myself?

As I am a newbie in working with the NIOS2, is there a good tutorial available which explains how to work with the ISP1362? I read all tutorials delivered with the DE2 board but none of these helped me.

I found something interesting at google (http://code.google.com/p/nios2-usb/), downloaded and tried to compile it - but it doesn't work either...

Hi there,

in the component editor, you 've got some columns: "interface" and "signal type". In the rows where the signal type 'export' is marked in red, you can change the interface type from 'avalon_slave_0' to 'export_0'. then you can switch the signal type to export (marked in black).

We've implemented a Nios2 cpu, a sdram controller and the ISP1362_CTRL.v in our project. It compiled without errors.

We are also new to this stuff and btw. we're also students from germany :)

After upgrading to a full version of Quartus II we were able to build a NIOS2 Core which fits our needs perfectly. After that, we built a µClinux OS for the board.

a very good tutorial for beginners: http://www.hs-augsburg.de/%7ecarcass/nios2-uclinux/uclinux_nios2_devicedrivers_and_testapplication_documentation.pdf

Hi Schnapphase,

I run into the same problem and got a Java "Internal Error" message, but later I have noticed that if you switch Interface to conduit_start then you can select Signal Type export.

After this change the SOPC gereted my User Module without any errors in Quartus II 7.2 Web Edition.

Hi there,

Since I'am working with De2 and ISP1362 Usb controller, and I hava a lot of troubles, can you please tell me your experience?

From link that you give (http://nioswiki.jot.com/wikihome/ope...clinux/usbhost (http://nioswiki.jot.com/wikihome/operatingsystems/%c2%b5clinux/usbhost)) I can't find anything.

Can you send me this SOPC code for ISP1362 from this link ?

Thank you very much for your time and effort.

Regards,

Bojan
