Our customer’s controller uses two Xavier modules to carry the customer’s own carrier board, one is the master module and the other is the slave module. Put it in the incubator for high temperature test.
High temperature 70℃, heat preservation for two hours. The master module is normal, the slave module can get up, and the power supply is normal. But the system cannot be loaded from the module. No information is printed on the debug serial port 3. Cool down to 60 degrees Celsius and return to normal from the module.
The customer used NV’s xavier DK for comparison experiments, and NV’s Xavier DK was normal.

what is the reason? Why does the Xavier module fail to load the system at a high temperature of 70 degrees Celsius? Please give your suggestions, thank you very much.

Did you get the log by keep increasing temperature until failure happen? Or use tegrastat command line to monitor the temperature value got until failure happen? If no related info printed, it is hard to tell what happened.

If this failure only take place on custom design and is only related to thermal, then it might be the custom carrier board issue of thermal design or some components will fail under high temperature. It needs to compare the custom design to reference to find out. There is a checklist table in OEM DG doc and also there is schematic of carrier board of dev kit for reference.
