Sometimes SHUTDOWN_REQ* not assert

Hello,

We have designed a custom board for the Jetson Orin NX, but we are encountering an issue with the shutdown process. Occasionally, when we use the shutdown command, the SHUTDOWN_REQ* signal is not triggered, preventing us from deactivating POWER_EN.

I have checked the pin with an oscilloscope, and sometimes I can see the interrupt is triggered as expected. However, there are instances where it doesn’t trigger at all.

Has anyone else experienced this issue or have suggestions on how to resolve this behavior?

Did not hear such issue before. From hardware side, you may need to check the custom design based on the checklist sheet attached in the Design Guide doc and compare your design to reference schematic to find out root cause.

I checked our design and found we used a 10 kΩ pull-up resistor on the SHUTDOWN_REQ* signal instead of a 100 kΩ. Could this be causing the issue?
