Cyclone V GT Programming Sucess in Tool but not working

Hi Team We have designed one custom Board with Intel Cyclone V FPGA GT with part number 5CGTFD5C5F27C7N. 1. After doing power up, we connected JTAG and tried to program FPGA. FPGA got detected in...

What's the HDL design you are trying to implement? You say you are toggling a test point. I presume you mean you've made a pin assignment and set an I/O standard for that pin?

Here .. we tried to program an LED blinking. But LED is in continuous ON Stage. Not Flashing. Also we have an 48Mhz crystal, that we tried connecting through FPGA to an test point. In that test point .. also signal is showing always high. Till Crystal to FPGA 48Mhz is coming. From FPGA to test point signal is always high. Also in Tool all unused pin we tried to pull low and checked on gpio connected to test point. Still test point was giving high. So we are not sure Whether FPGA is getting programmed or not.

But in quartus tool , it is showing as programmed and getting detected in Tool chain. Is there any problem in our Hardware connection.

Attaching one of the code i flashed.
