The self-developed motherboard cannot start when connected to Jetson Orin NX

[2350328892]

Hi，The self-developed motherboard is connected to the Jetson Orin NX core board (which can be started on the development motherboard). The core module generates heat due to power output, but there is no signal from the DP port connected to the display. Is this because the core module is not working or if the core module is working but the DP is abnormal?

This is the circuit diagram of the DP port

Jetson Orin NX core board (which can be started on the development motherboard).

It looks like your custom design issue.

Hi
What are the conditions required for Jetson Orin NX module system startup? Can it be started with normal power supply and activation? Why is my module powered and enabled normally but unable to start? Do you need any other triggering conditions?

You can probe the power on sequence as listed in the Design Guide. Basically, if the sequence is correct and all pin status are correct too, the system should be able to power on normally.
