qcom MTP VS EV board(failed).
From log we can see the MTP is OK, and there is not any information of TX&RX.
And there is some information to offer you:
a) There is usb of D+ or D- is OK, and the other can not be recognized from log.
b) DisplayPort Mode can not be got any information from log.
Btw, HPDIN is designed to be Float state, and is there any issue about it?
Pls. kindly help to check it.
Many thanks!
Best regards
Luck Wu
