Hi all,

i also have this often re-occuring problem, could you please help me? Thank you in advance.

I have followed the example you may find in tt_nios2_hardware_tutorial.pdf (altera website.)

Everything goes fine to the point where I need to upload the program...

Then I get the error which I have mentioned above.

what could have gone wrong?

I use nios II IDE 7.0 and quartus II 7.0 for the DE2 (EP35) education board. (with one usb cable)

* I only use the free license.

> Could this be causing the problem?

* In the tutorial I have read the following:

"You must have an Altera USB-Blaster download cable, revision B or higher."

> How can I check if this is the problem?

I also have following questions:

- is there anybody who has succesfully completed the example?

(on the DE2/EP35 education board, with free license)

- are there other causes for my problem?

once again thank you in advance.

Some additional info:

I can create a simple NIOS II core in hardware on which I can upload a simple program with the "Altera Debug Client". For more complex programs I however would like to use the NIOS II IDE
