Is this your own custom board, or an off the shelf development board?

If it is your own board, you need to have wired up some pins as UART RX and TX to external RS232 transceivers (or LVTTL if you are directly using LVTTL levels).

FPGAs typically will have no predefined pins for such generic internal logic. It is up to you to assign.

Hi ak6dn,

Thank you for you are reply. My bored is not my own custom made it was manufactured by TERASIC company. i have one more board that is ARRIA V V GX 5AGXFB3H4F35C4N, which was released by Intel i self.

i went through both the data sheets but i cannot find the UART RX and TX to external RS232 transceivers (or LVTTL).
