TX1 carrier board Automatic restart why?

Reference to the NVIDIA development kit, we made a number of Carrier Board I’m sure TX1 moudle is OK.Automatic restart time is uncertain, and sometimes work will automatically restart after a long time.

Can’t give precise suggestion as no details. Generally in hardware perspective, the auto restart is due to overheat or wrong operation on power on trigger signals. Is this related to this topic of yours: https://devtalk.nvidia.com/default/topic/1023320/the-carrier_pwr_on-signal-is-0v-why-/?offset=10#5206861

thank you for your reply
I still have questions Automatic restart is an uncertain time, sometimes a day to restart once and sometimes restart will be very frequent

Any log?
