unable to build a program in NIOS II IDE

Hello Berkoka,

Getting nios up and running can be a real challenge.

You do a number of steps in qsys, generate a vhdl / verilog application compile it and download it.

And then, hope that it works ...

If not it can be really difficult to try.

You can have a lot of different causes of problems that make it go wrong so some ideas:

=> Were you able to build a simple application verilog / vhdl that makes a led blink with your board in quartus?

(=> Just to make sure board, communcations, clocks work ? (Test))

=> In qsys, make an application with only onchip ram, no SDRAM, SDRAM and SRAM are possible cause of problems. Just the basics.

(=> In line with tutorial normally.)

=> In eclipse, generate application based on hello world small. (based on .sopc) hello world can be too large for some fpga's.

=> If you start the application in eclispse, click right on the project, and then use debug as Nios II hardware.

=> Sometimes you can have a problem with timestamp or id, you can check ignore mismatsched timestamp and id if you go to application, right click, debug applications, tab 2.

Good Luck,

Johi.
