4.3 Running the Demo Through UART

The following steps describe how to run a demo using UART if the host PC PCIe slot is not available:
Check the Device Manager of the host PC for UART ports. 
The following figure shows the example of UART ports in the Device Manager window.

Figure 4-17. Device Manager—UART Ports
The following steps describe how to run the reference design using UART IF:
  1. Go to All Programs > PolarFire_PCIe_GUI > PolarFire_PCIe_GUI. The PolarFire PCIe Demo window is displayed.
  2. Select UART radio button and click Connect.

The GUI application scans for UART port and after successful connection, displays the DMA Operations UART tab, as shown in Figure 4-18.
