EP1C12 Eval Board

I tried to run the EP1C12 alone on the EP1C12 Eval board. I wrote a small code to use the LEDs (2 to 11) on the board using VHDL, and I loaded to the board using .sof file, Nios II Eval Board (USB-0) at mode JTAG. While loading the LED on the EP1C12 module (2x2 module) dimmed, and it lights up again when programming was done. None of the desired LED lights up. I looked at the schematic, and notice that there is an EPM7064 hang on the TDI, TDO, TCK, and TMS. Would this EPM7064 over write what I just programmed? If it is how can I use the EP1C12 alone for other test without being interfered by EPM7064? Please help. Thanks for your time.

Regards,

MTDV

    Well, I found the answer, so I post it here FYI. You need to set all unused pins to "input and tri-state", and select your serial configuration chip. Re-compile, load the .sof file, and everything should work as you expected. If you want to store your .sof file on the configuration chip, you need to convert it to the jic file. Load jic using the programmer. That's it. Hope you all have fun.
