I am designing a custom carrier board for Jetson Nano Module.
When the HDMI port is not connected to the device, it can boot normally.
However, after the HDMI interface is connected to the monitor, it cannot be turned on normally. Oscilloscope shows that when power on SHUTDOWN_ REQ*(FORCE_ Off *) pin will have low pulse, resulting in Power_EN pin becomes low after a high pulse.
What conditions will enable SHUTDOWN_ REQ* when power on。
