I am new user to FPGA (Nios II, Cyclone II EP2c35F672c6) and presently trying to implement a simple VHDL code. Downloading the .sof image to the device using JTAG USB blaster is successful. But after downloading, the device again shows the same factory program and yellow LED is ON

How can I make the device to run my user program? Is that related to switching to user mode?

I tried the following things as suggested in forums:

1. selected "Enable error detection CRC" in Device & Pin options

2.Unused pin > reserve all unused pin = As input tri-stated.

Plz help!

Thanks
