We are having issues with our Xavier NX not fully booting or failing to communicate over CANBus when it is below -25C. What is the expected behavior? Is there an artificial mechanism preventing the system from working or is it something else? Is it similar to this: TX2 NX coldstart at -40°C?

it won’t boot if temperature is below -25°C, your question is the same as TX2 NX coldstart at -40°C - Jetson & Embedded Systems / Jetson TX2 - NVIDIA Developer Forums
@kayccc thank you for the input here. Is there a specific temperature location and/or zone that is being measured for the -25C threshold? Or is this it a sum-average type scheme across all of the zones on the SOM
The thermal design guide walks through an example to monitor thermal_zone0.
cat /sys/devices/virtual/thermal/thermal_zone0/type
cpu-therm
# cat /sys/devices/virtual/thermal/thermal_zone0/temp
35000
You need to provide a resistive heating element with an independent temperature switch that keeps heating until -20…-15°C and turns heating off and Jetson on when the temperature has been reached.
