I can not give you the answer. I just ask you, what do you want to do with the program?

If you want to learn something about kernal and IO programming, read "linux device driver 3rd Ed".

There is a chapter about timer. Read some codes in the kernal drivers will help too.

If you want to learn about avalon peripherals, do it with HAL will be easier.

The first timer in the system is used by kernel. And you should not touch it.

Add a second timer to play with.
