Reading from UART on an Oscilloscope

Former Member

Hey guys.
I've been trying to send a Hello-World-like program through my UART0, since I'm not intending to use the USB-UART converter. I found out in Vivado that I can select some MIO ports to the UART0 I/O, but here is my problem:
I want to read the signal on an Oscilloscope, so I need to pull the TxD and RxD from somewhere in the board. I couldn't find anything related to it. I find the MIO's being in bank 501, but where are they?
How can I assign the UART to pins in the board?
Sorry if this is a stupid question - I'm pretty new to this kind of thing.
Thanks in advance,

    If you double click the Zynq Processing System IP block in your Vivado Block Diagram to 're-customize' the block you can select 'MIO Configuration'. Then you can configure UART1 to be routed to one of the MIO signals connected to the MicroZed PMOD connector (int this case MIO 12-13 will work). You can select to enable a pull up in the same dialog box.

    Other options would be to select UART0 and select one of the other MIO signal pairs connected to the MicroZed PMOD port. If you are using a Carrier Card with your MicroZed you could route the signals from either UART1 or UART0 to EMIO and then assign them to PL IO.
