Hi Mark,

Are you running the Out of Box demo software using the mmWaveDemoVisualizer or do you have one of the other mmWave demos flashed on your EVM?

1. Please ensure that you have the EVM setup in standalone mode using the physical setup settings provided on this page.

2. Please reboot the board in functional mode using the settings described above and connect a terminal program (e.g. teraterm) to the XDS110 Class Application/User UART port using the following settings. Then type the version command (do not connect the mmWaveDemoVisualizer):

mmWave COM ports shown in Windows Device Manager

TeraTerm settings

Thanks

Hi - USB was very intermittent, i got Terra term functional, and eventually after lots of power cycling, plunging in and out the USB cable I managed re-flashed the board with the latest rev - it now works fine.

This is issue is now closed - thanks
