Orin system sometimes will stuck

[ckt10101]

Hi,
I use AGX Orin 64GB with jetpack version is 5.1.2 and Linux kernel version is L4T 35.3.1.
I found my system sometimes will stuck about 400ms. When it happened, no can message:

v4l2 polling will timeout.
“eth1” networking card will not notify received message.
But application logs still print, so CPU may stil alive.
And syslog has no error report.

So any suggestion to trace this problem?

Hi ckt10101,

@ckt10101

I use AGX Orin 64GB with jetpack version is 5.1.2 and Linux kernel version is L4T 35.3.1.

L4T R35.3.1 should be included in JP5.1.1.
Please share the result of the following command.

$ cat /etc/nv_tegra_release

Are you using the devkit or custom board for AGX Orin?

@ckt10101

I found my system sometimes will stuck about 400ms

How do you know about 400ms?

May I know what’s your use case and how do you reproduce this issue?

@KevinFFF

cat /etc/nv_tegra_release

cat /etc/nv_tegra_release
# R35 (release), REVISION: 4.1, GCID: 33958178, BOARD: t186ref, EABI: aarch64, DATE: Tue Aug  1 19:57:35 UTC 2023

I use custom board as I told on other thread.

How do you know about 400ms?

I count camera, can bus and lidar lost frame.

May I know what’s your use case and how do you reproduce this issue?

It happened when robot on automatic driving, and I don’t know how to reproduce.

We would need the detailed reproduce steps to verify on the devkit to perform further debug.

It seems you are using the custom board, then I want to know if the devkit has the same issue.

For the error message from mttcan, may I know what’s the bitrate you used for CAN?
