We have a Xavier AGX module on a custom carrier board. It appears the OVERTEMP_N signal is being driven low as an output from the AGX module. We do not have a fan on the unit as it is passively cooled with a heat sink, but the unit is certainly not over temperature.
What could cause the OVERTEMP_N output to be driven low? Are there any other dependencies on this output signal besides the current temperature?
The same AGX module mounted on a dev kit carrier board has no problems powering up, but it does not power up on our custom carrier (using the same schematic as the dev kit carrier board) due to the OVERTEMP_N signal being driven low. When we bypass this output on our custom carrier, all is good.
