NIOS TSE initialize

I understand that those reference design can help me to understand on how to control the TSE. But I cannot download it to my development board after I compile it on the NIOS SBT (I can sure I already program the FPGA with proper sof file).

Also I cannot find those code for initialize the TSE within the simple socket server example. The example use UCOS and nichestack. And it call some UCOS function to initialize the system but I cannot view the code in detail.

Another major concern is both of them is not free of charge, so I intend not to use both of them.
