Configuring UART0

Former Member

Hi,

I an running eCos on zedboard. By default eCos is configured to UART 0. I would like to configure UART 0 (similar to UART 1) and get the output on host machine through terminal (putty).

In vivado for zedboard, UART 0 is set to EMIO as IO.

1. I would like to know how this EMIO output can be accessed via terminal (putty console) in host.

2. Can we access UART 0 output via USB-OTG port of zedboard.

Thanks in advance

    1.   UART 0 may connect to EMIO by default, but you could also manipulate it to connect it to the PS Pmod. EMIO is also valid, but then you have to provide constraints to specify which pins to use (the PL Pmods would be a good choice).
       
        This gives you a UART at the SoC pins, which is not enough to connect to a PC. You also need a transceiver. I suggest you look at USB-UART or RS232 Pmods.
         
    2.   No

    Honestly, you'd save yourself a whole lot of time by figuring out how to configure eCos for UART 1.
