problem to run nios2-terminal

I have installed Quartus and nios2 9.1 sp2 on centOS5 to use uclinux. Now i am using the example of the Nios Community WIKY called TryOutuClinux on DE2 board. I have downloaded the sof and and the kernel image but i cannot run correctely the nios2-terminal.

This is what happens in my shell:

" [NiosII EDS]$ nios2-configure-sof

Searching for SOF file:
