Gk20a and Jetson Nano crash

Many thanks for this summary.

So only B01 board has the pcie error, right?
Does every of them on the list hit the gpu error?

Hi @WayneWWW,

I took some time to get back to you because I wanted to be relatively sure that the problem was solved.
I have tried to run the following configurations

Date Seconds Hours Model Boot Pwer Supply PCIe error What new
17/09/20 82655 22 A02 SD 5V, 4A No JetsonClocks activated, NO CRASH
21/09/20 110970 31 A02 USB3.0 SSD 5V, 4A No JetsonClocks activated, NO CRASH

I have recorded no crash with the jetsonclocks activated!
That solved the problem apparently.
The temperature of the A0 sensor is also lower (35°C on average now).

Also in the previous table, when you read NO CRASH that means that I had no problem. Unfortunately, that happened only when I had NO inference running before discovering that jetsonclocks was solving the problem.

Do you think that the dynamic management of the GPU voltage due to Dynamic Voltage and Frequency Scaling (DVFS) might have created such a malfunction after long usage?

Thanks!!

Hi @WayneWWW,

We encountered the same problem. The PCIe error:

I’m not always getting the kernel panic. When the device keeps running and I restart the deepstream application I see following error:

Will you guys please look into the issue? You found any problems in the frequency scaling governour?

Could you confirm if using jetson clocks can also resolve the error too?

The device is running for 16 hours and I ran jetson_clocks at boot. As we see in previous logs the error occurred after 51 hours (183917 seconds). So I can confirm on Monday.

Are there any side effects for temperature? At the moment I don’t see an issue but the environment temperature is only 11 deg Celsius, in the summer the environment temperature can be alot higher.

You guys looked into the DVFS governor already?

Hi,

are you using a fan to cool down the Nano?
While I was running the tests I was logging the temperatures with a modified version of this script in python: https://github.com/tsutof/jetson-thermal-monitor
Maybe that might be helpful to undestand whether the temperature is reaching high levels.

However, I have never encountered your errors.
