Jetson TX2 - Reboots itself randomly

I am using “Jetson TX2” with “Connect Tech Orbitty Carrier” board. It is rebooting itself on random times. I have checked the system usage and temperature everything seems normal. Temperature is around 40 C and the board reboots itself even during the boot and when there is no application running.

When I type the following commands into the terminal

> cat /proc/device-tree/chosen/reset/pmc-reset-reason/reset-level 
> cat /proc/device-tree/chosen/reset/pmc-reset-reason/reset-source 
> cat /proc/device-tree/chosen/reset/pmic-reset-reason/reason 
> cat /proc/device-tree/chosen/reset/pmic-reset-reason/register-value 

I am receiving the following outputs in order:

0
SYS_RESET_N
NIL_OR_MORE_THAN_1_BIT
0x50

So can it be a power supply problem? I am using a 48 V battery and 48 V to 12 V DC/DC converter to power Jetson TX2. It should be stable enough. What else can be the reason?

Thank you for your help in advance.

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

Is there a same problem when you power JTX2 with normal AC adapter? Is there UART log when system reboot happen?
