2.8 XDS110 Interface

J5 provides access to the onboard XDS110 (TM4C1294NCPDT) emulator. This connection provides the following interfaces to the PC:

  • JTAG for CCS connectivity
  • Application/user UART (Configuration and data communication to PC)

When used in standalone mode of operation as shown in Figure 4-30, the power is supplied through a single USB connector; the same USB connector J5 is also used for configuration and data transfer through the XDS110 USB to UART converter. When enumerated correctly, the 2 UART ports from the XDS110 are displayed on the device manager as a virtual COM Port, similar to that shown in Figure 3-24.

If the PC is unable to recognize the above COM ports, THEN install the latest EMUpack. Similar to that shown in Figure 3-23.

EVM uses single UART port for both device configuration and processed data communication to PC.
