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".

How can i access the uart in my vhdl, is there any another way?

 

best regards

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:

Thank you

Is it possible at all to use the pin planner to map to the UART pins? The reason I am trying to do this is that I need to be able to transmit data at speeds close to 1Mbaud. According to the FT232 data sheet this baud rate is possible.

Are the UART pins then directly connected to the USB mini-B connector on the DE10 nano?
