What is wrong with my design?

[Altera_Forum]

Hello, 

 I followed the Altera Hardware Example Design on my Microtronix Cyclone DevBoard. I have tested the LowCost Design, and every Software Example Designs(in the Design Support Matrix) can run well. But when I do the Standard Design, when I download the "Hello_LED" example, there display in the IDE console with  "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: errata.txt included in the Nios II development kit documents nios2-terminal: directory for more information.  nios2-terminal: connected to hardware target using JTAG UART on cable nios2-terminal: "ByteBlasterII [LPT1]", device 1, instance 0 nios2-terminal: starting in terminal mode only (Control-C exits)."  It stop here, and nothing happen on the board. I tried other example(hello_world, ......), the same with above. I do not know what the reason is. Can guys tell me?   Thank you very much.

It's probably best for you to try and debug the system instead of running it. 

 It it doesn't get to main then try stopping at alt_main and stepping through the code from there to find out what the problem is.  The next step depends on whether you can do any debug at all.  (The warning message is warning you about intermittent failures. ByteBlasterII should work most of the time, but its not guaranteed, hence the warning message).

What *Blaster are you using? Also, I agree with LiangYi that it is best to DEBUG the system. It could be that it is working, but messages/lights are flying by so fast they are not visible to the naked eye http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/smile.gif   Good luck!

Hi, 

I tried on my board for standard design for Hello LED Display and it works fine. I think debugging is the best solution for this problem as others mentioned.  thanks rao
