theUltimateSource Posted January 28, 2018 Share Posted January 28, 2018 Hello, just plugged in my new Zybo Z7 471-015 but cannot connect to serial port. It works on the Zybo. PROG UART is connected to USB PC BSP stdin, stdout is set to ps7_uart_1 I have no other application open that is accessing the serial ports to make sure I dis- and reconnected the Zybo Z7, still doesn't appear on the port list Zybo Z7 appears as USB Serial Converter A and B in the device mngr restarted PC tried another USB port replaced USB cable, both are data cables JP6 is set to USB JP5 is set to JTAG drivers had been installed with Vivado 2017.2 re-installed Vivado 2017.2 cable drivers, restarted PC USB port should be listed even without any PL configuration loaded, right?

theUltimateSource Posted January 29, 2018 Author Share Posted January 29, 2018 I searched for inactive driver in the Windows device manager and found out that there appear 2 x USB Serial Converter A and 2 x USB Serial Converter B. I deleted all of them and powered the board. Now both boards work. Link to comment Share on other sites More sharing options...
