Change behavior of NVIDIA® Jetson Orin™ NX if power signal is continuously on

[marcos.oliveira2]

I’m interested in change the behavior of the power signal on NVIDIA® Jetson Orin™ NX. I need to turn on the board automatically as soon as I receive energy from the power source.

I’m currently wiring the connection of Front Panel Connector (CN24) pin 13 to a relay that’s turn on the board when charged. However, as the signal remains up, the firmware shuts down the board after 5 seconds.

I need to know if there is some firmware tool or some configuration that’s prevents the board to turn off if the power signal is continuously on.

Front Panel Connector (CN24) pin 13

What’s this CN24? Are you testing on devkit or custom board? If latter, please check with vendor for this.

I’m testing on BOXER-8653AI ( BOXER-8653AI Manual 1st Ed-1.pdf (aaeon.com)), powered by an NVIDIA® Jetson Orin NX™ 8GB with Linux NVIDIA Jetpack™ 5.0 OS.

The pin 13 on the board should send the same signal as POWER_EN.

My main concern is just to prevent the board from powering off when the signal POWER_EN remains up. There is some way of preventing this behavior on the board ?
