Problems when downloading onto EP1S10F780C6

neo,

This is telling you that something in the system has been updated but the hardware (.sof) was not re-compiled; a common cause of this is if you open the hardware portion of the design in SOPC Builder, edit something, and then close (or re-generate).. such actions will update the time-stamp in the configuration (.ptf) file that stores information about your system. You should either turn-off the system-ID checking mechanism in the IDE (if you know that you have not made any system changes), or re-generate in SOPC Builder, and re-compile in quartus to get a new .sof.

I ran the "re-generate" in SOPC Builder then ran the "start-complie" from Quartus II 4.2 "processing" menu.

Then I run the "start" from Quartus ---> Programmer.

Then I re-build the "Hello World" and tried to download it onto board. But I failed again and got the following error message:

Using cable "ByteBlasterII [LPT1]", device 1, instance 0x00

Pausing target processor: not responding.

Resetting and trying again: FAILED

Leaving target processor paused

BadOmen/Jesse,

Thank you very much for your help on this issue.

Now, it seems I almost solved that problem when I got the following information:

Using cable "ByteBlasterII [LPT1]", device 1, instance 0x00

Pausing target processor: OK

Reading System ID at address 0x021208B8: verified

Leaving target processor paused

But I also got the following warning message ...

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: "ByteBlasterII [LPT1]", device 1, instance 0

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

Hello from Nios II!

So must I use USB Blaster revision B cable?

And from the "Getting Started" document, it seems OK when the "Hello World" is printed onto the terminal window of the Nios II IDE.

If I want to print something out onto the LCD, how could I do?

Thanks,

Neo

You can use a ByteBlaster cable, but if you are in a noisy environment then you might have problems with nios2-terminal or the debugger disconnecting or unexpectedly reporting errors.

See the web server example, file web_server.c for an example of how to print to the LCD.
