My new board was made by referring to the TX2 Development Kit C02 circuit.
However, when booting with TX2, HDMI enable IO and USB enable IO are disabled(Low), so the external interface cannot be used.
when IO enable is forcibly set to High with TX2, the HDMI output screen appears but not fine USB, so it was checked that booting was successful. & ethernet connection is fine (with ping command)
when IO enable is not forcibly set to High with TX1, the HDMI output screen appears and also be fine USB, so it was checked USB data line.
VIN_PWR_BAD_L and POWER_ON is DC 4.7V
What are the conditions that fail to enable external interface IO and function (HDMI&USB)?
Hi, if it is board design issue, you need to check the difference between your design and dev kit C02 board on HDMI & USB part and try to eliminate the difference. Also there is a check list in OEM DG which can be used to check design items one by one.
