Hello. I often encounter abnormal restart issues when using Xavier on my custom device. and I have ruled out hardware factors.
Here is the kernel log of my phenomenon when it occurred.
After experiencing an abnormal restart. I observed my reset source. but I am not sure what caused this reset source.
This issue is urgent for me and I hope you can help me quickly. Thank you very much for this.
The attachment below is my complete system log. 104_ai3_kern.log (36.3 MB)
tegra-pmc: ### PMC reset source: BCCPLEXWDT means watchdog triggers reboot because CPU has been hung for too long. If it’s some software issues, then it should happen on DevKit, too.
Take a note of what kind of applications you are running before the abnormal restart, and see if the phenomenon can be consistently reproduced.
Are you saying there is a problem with my software? But when I no longer run the application on xavier, it still appears. How can I avoid this situation? This is very important to me
I don’t know what programs you are running so I cannot comment much.
You mean you just put the device there without doing anything, but you still got BCCPLEXWDT?
Watchdog triggers reboot if the system has not responded for over 120 seconds.
Please try the same workflow on DevKit and see if it’s still there.
Also dump the serial console log before the abnormal restart happens.
When I don’t run the program, it still experiences abnormal restart. Below is my kernel log when the problem occurred. he appeared twice in total. 104_ai3_kern.log (36.3 MB)
Additionally. I would like to confirm that I don’t think this Watchdog mechanism is necessary. How can I disable it? It caused me to restart abnormally.
你給的那串kernel log老實說根本沒用,那只能知道是watchdog觸發的reboot,但是沒辦法知道原因
(通常會戳到watchdog,要嘛是系統卡死、或者kernel panic之類的)
我問你是不是機器擺著、什麼事都不做也會中
你只說When I don’t run the program,但是我根本不知道你所謂的the program是什麼
