Use this port name in the 'Serial line' field when opening PuTTY.

In the screenshot below, the USB-UART interface is COM14.

Look for the port named 'USB Serial Port' and note the COM number assigned.

Open Device Manager (run 'devmgmt.msc').

In our experience the FTDI drivers assign a new COM port number to each unique board.

In Windows the connection is named COMX, for some integer X.

The name of this connection is not fixed. When you connect the USB-UART interface to your PC, your OS will emulate a serial port connection. This will save your defaults and apply them every time PuTTY launches.Click Default Settings, then click Save.Enable 'Implicit CR in every LF' and 'Implicit LF in every CR'.Launch PuTTY you should see this window:.

We recommend adopting the following settings. There are many options for terminal applications. Although the boards use different FTDI devices, they use the same driver.ĭownload the drivers for your OS from the FTDI drivers page: .īe sure you install the VCP driver (Virtual COM Port). The basic steps to using the USB-UART are:īoth WARP v2 and v3 use USB-UART transceivers from FTDI. The instructions below apply only to the USB-UART. The WARP FPGA Board v2 (Virtex-4 FPGA) provides both a USB-UART and a RS-232/DB9 UART. All WARP reference designs connect STDIN/STDOUT to a UART. The primary use of this interface is to interact with STDIN/STDOUT of embedded processors. WARP hardware uses a USB-UART transceiver to interface between a PC-based terminal and a UART in the FPGA.
