  • Hi Aggil,

    Are you using the USB as the source for your input signal? Based on the image it appears so.

  • Hi Aggil,

    Please also double check the EVM configuration(like jumpers, switches...) with the quick start guide on EVM User's guide.

    Hi Aggil,

    Did you also press the input button to make sure that it's on USB? Based on the picture you sent it doesn't appear so.
