Dears:

We guess there is something wrong with our EVM, since we got wrong information about HDMI state.

And we got the signal of 5V RX.

Is there any issue about hardware?

Thanks a lot!

Best regards

Hello
Can you explain further what state you were expecting to see and what resolution you are feeding into the part? I see that 5V_RX is indeed detected

Dear Steven:

Pls. refer the below picture, and the signal's resolution is 1920*1080.

The HDMI HPD's state is False although RX_5V is detected.

Is there any problem about the Hardware of EVM? Since before the EVM is OK.

Thanks!

Best regards
