Hi,  
I am facing the following issue on my Xavier carrier card.

When I am shutting down my system from OS my board is resetting instead on Shutting down. Are there any signals on Xavier which could wake the module from shutting down?

I also want to know what should be the state of MODULE\_PWR\_ON(L54) pin on the module when we are performing the shutdown from OS. How is this signal handled on Eval carrier? I understand it is an MCU controlling this signal. What are the signals which will affect the MODULE\_PWR\_ON signal?

To add on to the above query, the power button switch is also not functioning. I have held the power button signal low for more than 10 seconds but the system does not switch off.

Hi roshan.dsouza,

You means, you press power button over 10 secs, the device can’t power off?

Yes, correct,

Also, in OEM product design I am able to see that POWER\_BTN\_N pin type is CMOS-1.8V, but in eval board schematics this signal is pulled up to 3.3V.

Please, could you also reply to my first query also?
