[FAQ] Sticky: Enable XDS100 USB Serial Port on LAUNCHXL-F28069M

Guru 62975 points
Part Number: LAUNCHXL-F28069M

The XDS100 USB Serial Port on some LAUNCHXL-F28069M boards may not be configured correctly.  A symptom of this condition is that the USB Serial Port will not be identified by Windows.  Below is a snapshot of an XDS100 USB Serial Port port that is correctly identified in the Device Manager:

If the serial port is not identified on your LAUNCHXL-F28069M, you can reprogram the XDS100 EEPROM using the following steps:

  1. Download MPROG 3.5 from FTDI
  2. Extract and run MPROG
  3. Connect your LaunchPad to the PC
  4. Device >> Scan to find your XDS100
  5. Tools >> Read and Parse to decode your programmed settings (only continue if the following are true)
    1. The Product Description includes XDS100
    2. The Side B Driver is set to D2XX Direct instead of Virtual COM Port

  6. File >> Save As (for backup)
  7. File >> Edit 
  8. Update the Side B Driver to be RS232 UART + Virtual COM Port
  9. File >> Save As (your choice)
  10. Device >> Erase
  11. Device >> Program
  12. Unplug LaunchPad
  13. Plug in LaunchPad

After the above sequence, your USB Serial Port should be identified in the Device manager.
