Add UART0 causes print to stdout fail

Former Member

I took first set of tutorials and they functioned fine.  I added UART0 to project and rebuilt.  Now when I run peripheral test none of the "print"s show on the console.  If I remove it they are back. Also I can't get an output on UART0 either.

    When you added UART0 to the project the BSP was generated to use it as the STDIN and STDOUT ports for the console by default. You can change that back to UART1, the UART connected via MIO pins to the USB-UART converter, by right clicking on your BSP in the Project Explorer pane on the left in the SDK and selecting 'Board Support Package Settings'. Then go to the 'standalone' setting in the dialog box and change the stdin and stdout to ps7_uart_1.

     

    The UART0 IO is connected via EMIO to the PL (Programmable Logic) section of the Zynq device so you will need to connect the serial port signals you want to use to PL I/O pins. Then you will need to connect the I/O signals from the Zynq device through the JX1 or JX2 microheaders to some interface, such as a PMOD, on your carrier card. You could use a PMOD RS232 converter to connect to a serial port.

    The Uart 0 setting was the bsp setting.  So now I get the console back but running the UART0 from the peripheral test gives a failure.  I have tried multiple times to fix.  Even ask local FE with no response.
