Hi NVIDIA:
We do the cold run test at -40°C. The UART console from the ORIN NX indicates that thermal trip is enabled, and when we try to raise the temperature, the ORIN NX reboots by itself.
Best regards,
Ben
Not sure what you are trying to report here. Orin NX lowest operating temperature could only be -25C.
Hi NVIDIA:
Thank you for your response.
We know that the operating temperature of the ORIN NX module is -25°C.
We would like to know what temperature can trigger the thermtrip function.
Do any documents mention the thermtrip function from the ORIN NX module?
Best regards,
Ben
please read
Hi Wayne
Let me rephrase the question our client wants to know.
We found that when the Orin log reaches around -21 degrees, shutdownreq sends a low pulse, the system shuts down ,
Subsequently, the system automatically boots up, stops at the log entry “enabling thermtrip,” and after a while, boots up again, repeating this cycle continuously.
We would like to know what will be triggered at low temperatures.
for example…shutdown_req ,Under what conditions does it assert a low pulse?
and is there a retry or reboot mechanism once the temperature rises again?
Best regards,
There should not have anything triggered at that temperature. Please share the log out.
Hi Wayne

The link is the complete log.

Best regards,
The link to the log is not able to get opened on my side.
Please attach it with forum system.
Also, I heard that this test is conducted on your custom board. Is it possible to do the same on NV devkit?

Hi,
I don’t see any error here.
Your log showed that the boot environment is in -38 to -37C.
[0000.748] I> enable_soctherm_polling = 0
[0000.752] I> max temp read = -37
[0000.755] I> min temp read = -38
Orin NX lowest boot up temperature is -28. So of course the boot up will get hang.
Hi NV:
Yes, just like the two situations mentioned on May 28, we couldn’t observe anything either.
Therefore, we would like to have more documentation or information regarding low-temperature protection, as we are trying to understand the behavior of shutdown_req and reboot.
Best regards,
Hi @ben.peng
不知道用中文討論會不會清楚一點. 請問你現在的問題到底是要問什麼?
這裡也重新講一下狀況. 你的問題就是很單純, 你的開機溫度就是比我們預設的min還要低, 所以開不起來
log裡面也有寫了min就是-28C (spec上的-25再少3度作為緩衝). 低於這溫度就是沒有辦法開機.
