DE10-Nano RX TX pin assignment

How can i assign in "Pin Planner" the pins HPS_UART_RX(PIN_A22) and HPS_UART_TX(PIN_B21) in my vhdl programm. I wan to send data over UART. "Pin Planner" shows the error message "Not assignable". ...

Hello,
If you want to use the HPS UART, you can use it without assigning it in pin planner, since it is hard coded already. You can use the UART IP in Platform Designer, and assign the TX/RX pins to any GPIO pins on the DE10 nano sides.
You can refer to this example:
