control_panel for DE2_70

Has anyone here had any problem using the DE2_70_control_panel.exe, file came with the DE2_70 dev. board? I am using Quartus II 10.0 web version and

Nios II EDS 10. Whenever I try to launch the DE2_70_control_panel.exe, as instructed in chapter 3 of the users manual, the following error message pops up: "The program can't start because jtag_client.dll is missing from your computer. Try reinstalling the program to fix this problem."

"Load DLL (TERASIC_JTAG_DRIVE.dll) fail"

"Fail to connect to FPGA board"

I 'm not sure what these are about, but I know I was able to download the provided sof file to the FPGA via USB-blaster.

Can anyone show me how to correct this problem?

Thanks!

    After a whole lot of digging I was able to figure out what the problem was. I had to do two things:

    1) Copy over jtag_client.dll and dinkum_alt.dll from "QUARTUS_ROOT_DIR\quartus\bin" to the Control Panel software folder.

    2) Add the following two directories to my windows system PATH variable:

    C:\altera\10.0\nios2eds\bin

    C:\altera\10.0\nios2eds\bin\nios2-gnutools\H-i686-pc-cygwin\bin

    Step 1 was courtesy of Terasic's tech support and has now been added to their technical FAQ webpage. Step 2 I figured out on my own and essentially consisted of having to go through each script and running them all manually until I figured out where they were failing.

    I have no idea why it is that some people have to do this fix and some people don't. Some people have no problems at all. Weird. Just FYI, my system is Windows 7 64-bit running Quartus and NIOS II EDS v10.0.

    Hope this helps someone in the future.

    Pz!

    hasil86,

    I still have the problem after I copy the jtag_client.dll and dinkum_alt.dll. So I have to do the second step from jwdonal. I think it depends. Some people already solved the problem by just copy that two things, some people still have problem.
