3.15 FTDI Interface

J10 connector provides access to the onboard FTDI ports. This provides the following Interfaces to PC:

  • FTDI Port A : SPI
  • FTDI Port B : I2C, HOST_INTERRUPT
  • FTDI Port C : UARTA, nRESET
  • FTDI Port D : RS232, SOP control

When xWRL6844EVM's FTDI USB is connected for the first time to PC, Windows® may not be able to recognize the device. This is indicated and confirmed in the device manager with yellow exclamation marks, as shown in Figure 3-29.

In order to correctly detect these ports on the PC please download and install the latest FTDI drivers available in the (C:\ti\mmwave_sdk_\tools\ftdi). This must be done for all four COM ports. When all four COM ports are installed, the device manager recognizes these devices and indicates the COM port numbers, as shown in Figure 3-30.
