SHUTDOWN_REQ pulled low before reaching Thermal Throttling

ralf.goebel · June 19, 2023, 2:55pm

We are experiencing a thermal problem using the Orin NX 16GB module on a custom carrier with our thermal solution:
The module is pulling the SHUTDOWN_REQ low when the SoC reaches a temperature of about 85°C. We verified that both LPDDR5 components do not exceed Tcase of 85°C like described in the Thermal Design Guide. The VDD_IN supply is also stable at 5V.

Test conditions:

15W power model
running memtester tool in parallel on four cores

Is there any other component on the module to check, or another condition that can cause a shutdown request?

Thanks,
Ralf

Hi, as said in DG: SHUTDOWN_REQ* is driven active (low) by the module if the system must be shut down, due to a software shutdown request, over-temperature event, undervoltage event, or other faults. Did you see any warning info output before shutdown?

ralf.goebel · June 20, 2023, 1:51pm

I don’t see any warnings before shutdown.

Trumany · June 20, 2023, 11:58pm

There is no clue then. Module won’t shutdown per the output info of tegrastats. Do you have log info?

ralf.goebel · June 23, 2023, 2:23pm

There is nothing in the logs regarding overtemperature or other problems.

I did some further tests by heating specific module components only. It looks like heating up the VDD2 regulator on the bottom side to about 100°C is causing the problem. According to the Thermal Design Guide, this regulator has a Tcase of 150°C.

Trumany · June 25, 2023, 1:35am

VDD2 regulator thermal shutdown threshold is 155°C. It won’t shutdown if only 100°C. Can you share full UART log when issue happen?

ralf.goebel · June 26, 2023, 7:11am

You are right, it’s not the VDD2 regulator. But I think it’s one of the components above the regulator:
Screenshot 2023-06-26 085344

Here is a thermal image of the situation while heating this area. The snapshot was taken at the moment the module is pulling SHUTDOWN_REQ:
Fail_3

This test setup is not using our thermal solution, because I replaced the SO DIMM socket by a vertical version to make the bottom side accessible. Also note that the system is idle.

Here is the UART log:

Trumany · June 26, 2023, 9:01am

Is the image of real use case or just heating directly? There are some shutdown_req related components there. Some capacitors temperature threshold is only 85C.

ralf.goebel · June 26, 2023, 9:14am

This is not the real use case. It’s a test setup to figure out what is causing the shutdown. You can see a hot air heater coming from the left side directed at the componets.

Trumany · June 27, 2023, 12:46am

I don’t think that is a correct test way. You should use a real use case image to observe if thermal at this zone will cause same failure.

ralf.goebel · June 27, 2023, 7:18am

Here is an image at the moment of failure during the memory test we use:

Screenshot 2023-06-27 075725

The hottest area is in the middle of the PCB at 94°C. The area in the upper left is at 90°C. The SoC temperature was close to the throttling temperature at about 97°C.

I did another test by attaching a small heat sink at the upper left mounting hole. This reduces the temperature in the upper left corner by about 5°C:

Screenshot 2023-06-27 090902

In this situation, the module doesn’t pull SHUTDOWN_REQ and it enters thermal throttling. Other regions of the board are even hotter than in the failing setup without the heat sink.

You said that some capacitors have a temperature threshold of 85°C. What exactly does this mean for us? Is this somethink that should be monitored?

Trumany · June 27, 2023, 8:06am

So, it won’t fail if you attach a small heat sink at the upper left mounting hole, right? What’s the tegrastats output info then? If SoC is about 97°C, the tegrastats info should be able to output that.

In addition, do you have a chance to test with board in horizental than in vertical? The upper left zone will be affected more in vertical.

ralf.goebel · June 27, 2023, 8:10am

Yes, the temperature is reported by tegrastats.
The orientation is already horizontal.

Trumany · June 27, 2023, 8:42am

Can you please share the tegrastats info at that moment? Also, can you try a test by removing C679 as below marked?

Removing the capacitor doesn’t seem to change the behavior, the module is still shutting down.

Got it. So,

A small heat sink at the upper left can help.
Removing C679 won’t help.

Can you try removing R377 as below? Removing it will cut off the thermal_shutdown signal, let’s check if shutdown_req is asserted by internal thermal sensor or by failure component. Be careful not to let SoC temperature overceed threshold.

ralf.goebel · June 28, 2023, 8:04am

The module is still pulling SHUTDOWN_REQ after removing R377.

Trumany · June 28, 2023, 8:43am

So removing C679 and R377 (0ohm) won’t help. Can you please try removing R329 (0ohm) as below?
r329

ralf.goebel · June 28, 2023, 8:48am

Ok, should I install R377 again?

Trumany · June 28, 2023, 8:54am

No, just leave it unconnected.
