Hi Niranjan,

May i know are you using USB Blaster II for programming? If it so, can you change the TCK frequency to 6MHz and try to program again?

HI SooYL,

I am glad to tell you that I solved this problem.

I am using USB Blaster II and JTAG.

Earlier JTAG was not working properly because of the PINs assigned in the .jic file code.

As FPGA boots from the .jic code in EPCS128 device, that code was blocking USB Blaster operation.

I tried to connect the board to PC through USB Blaster very quickly at the boot time of FPGA.

I captured a time interval in which Quartus could detect EPCS device. Here I made connection of EPCS and Quartus programmer over USB Blaster.

Then I flashed EPCS device with default.jic.

Everything is fine now.

Thanks for suggestion, though.
