Troubleshooting
DTE Top Level Menu is Not Displayed/USB Issues
•
As the USB cable is connected after the EVKit boots, the menu may be printed before Tera Term
connects to the DUT. Press the space bar a few times to redisplay the DTE Top Level Menu.
•
Sometimes it is necessary to unblock the USB cable, and reattach. Then press space bar to
redisplay the DTE Top Level Menu.
•
If the USB port fails to Enumerate, unplug cable, exit Tera Term and try again
•
If COM Port does not appear in Device Manager under Port (COM & LPT), Attempt the “Scan for
hardware changes” from the “Action” menu in Device Manager.
•
The serial UART to USB interface chip gets a new USB handle whenever the host PC is power
cycled or then EVKit board is power cycled. Any preexisting session via Tera Term may no longer
be valid. Exit Tera Term then reconnect. Avoid having the Test PC sleep or reboot during test
session.
