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:
- Download MPROG 3.5 from FTDI
- Extract and run MPROG
- Connect your LaunchPad to the PC
- Device >> Scan to find your XDS100
- Tools >> Read and Parse to decode your programmed settings (only continue if the following are true)
- The Product Description includes XDS100
- The Side B Driver is set to D2XX Direct instead of Virtual COM Port
- File >> Save As (for backup)
- File >> Edit
- Update the Side B Driver to be RS232 UART + Virtual COM Port
- File >> Save As (your choice)
- Device >> Erase
- Device >> Program
- Unplug LaunchPad
- Plug in LaunchPad
After the above sequence, your USB Serial Port should be identified in the Device manager.
