Ganesh,

Downloading the .sof image to the device using JTAG USB blaster is successful

How do you know this?

But after downloading, the device again shows the same factory program and yellow LED is ON

Then your design did not download correctly. Or, are you referring to putting your design into a non-volatile configuration device? If so, this will require a different process, which depends upon how you have the configuration device connected to the FPGA. What yellow LED? Are you using a development kit? If so, which one? I need a little more information here.

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.

CRC has nothing to do with device configuration.

Configuring unused pins as input tri-stated is the safe option. Again, this will not affect the configuration process.
