I have never heard about "kernel mode virtual addresses". I cant find information about it. Can you give me reference?

Please refer

http://www.altera.com/literature/hb/nios2/n2cpu_nii51003.pdf

table 3-2 at pp.3-4. In this case, you must use the partition 'I/O' and note that these ranges are all 'virtual address' ones.

About addresses: I have tried to use addresses that was generated by "sopc-create-config-files" tool. And it works.

If your purpose is only to drive leds etc., it is the easiest way. But if your purpose is to learn and make some Linux drivers, you must learn more.
