How to judge whether it is a cold start or a warm start

[wxsrite]

Hi all：
I want to know whether the current device is a cold boot or a warm boot. Is there any way?

Version：
JP5.1.2

Device：
Orin NX

Hi wxsrite,

Are you using the devkit or custom board for Orin NX?

Please share the full serial console log for further check.

Hi KevinFFF:
1、custom board for Orin NX.
2、I want to know if someone has unplugged the power supply by querying whether it is a cold start or a hot start.

You could just run the following command to know the reset reason.

$ cat /sys/devices/platform/c360000.pmc/reset_reason
