NicheStack CII

Hi there,

I've been implementing Altera Datasheet " Using the NicheStack TCP/IP Stack

Nios II Edition Tutorial, Jan 2007", but I'm getting some difficulties and I tried a lot to discover it and I couldn't do that. So please any one could help me finish this, I'd appreciate it, and Thank you in advance :)

The message I'm getting after run is

*************

Using cable "USB-Blaster [USB-0]", device 1, instance 0x00

Pausing target processor: not responding.

Resetting and trying again: FAILED

Leaving target processor paused

**************

properties

Hardware: Cyclone II Development & Educational board

Software: 1- Quartus II 7.2 web

2- Nios II 7.2 IDE.

    Your processor is not running. Either the CPU is in reset or some SOPC/QSYS components are not working at all.

    @ Socrates,

    Thanks to you for comment, but I wonder is there any specific technical support on Altera site or else where has a full descriptions and steps for Ethernet. Such as, "Rapid Prototyping of Digital Systems SOPC Edition by James O. Hamblen".

    Are you using a DE2 board with a DM9000A controller to Ethernet?

    Quartus 7.2 has LWIP instead Nichestack.

    Look that (terasic support):

    I am afraid that the DM9000A does not support to be initialized in the Quartus II 9,0 or later version. So it is quite difficuilt to port the DE2_NET project from NIOS II 7.2 IDE to NIOS II SBT 11.1 directly.

    In the Nios II v9.0 or later, the TCP/IP includes the networking stack of the Nichstack, however, the DE2_NET project was built on the LWIP. The driver for the DM9000A should be different in the Nichstack to the LWIP. Then, if you want to migrate the DE2_Net project to Nios II v11.1, you have to create a new driver for the DM9000A at first.
