Stratix IV - Flashing tools

Hi,

I am currently trying to configure the FPGA from the flash and the manuals are not very clear to say the least. I am using Quartus 12.0 tool chain on a linux platform. I tried following the Getting started with DE4 Board tutorial on programming CFI Flash. While running the sof2flash utility, I am running across this problem.

Although a flash file has been generated, I wouldnt know if its trust worthy. Any suggestions?
