Assuming the program is correct:

1) cross-compile it on your host platform
2) transfer the executable to the mini2440
3) run it and
4) hopefully enter your selection using the keyboard

Have you done step 1?

when i built code that Tahomy post, the result is "Error opening device or
no such device". Can someone help me?

Sorry, when i run code that Tahomy posted on Tiny6410, the result is "Error
opening device or no such device". Can someone help me?
