ALTERANiosII examples work on MicrotronixCyclone ?

Those designs were probably specific to an Altera NIOS kit. That design used flash from that board if I'm not mistaken.

To do you're own first hello world program I recommend starting from scratch (because then you know how do you're own

design). Add you're own design and populate some onchip RAM with the jtag downloader. The code they give you for the

software should be just fine to use.

Or you can just load that hardware design, open the SOPC builder for that design and remove anything that's not on you're

board (like the flash for example).

But I'd recommend starting with something small like a core, RAM, JTAG uart, and debug module then work your way up.

If you do that though expect the code to be huge without making the recommended changes in the IDE (without changes

it'll be around 67kB, and when you put the changes in it will be under 4kB)
