random reboot


Hello All,

I am running linux in an embedded environment. Once every couple of days my target reboots. Is there a way to know what the cause was ?

I have 6 target boards running same code, and only 1 had this problem over last 2 days. Its not board related, as I have seen it do on other boards.

Same boards when loaded with previous rev of code, didnt do this.

I am looking for something that gets logged before the system reboots.

Thanks,

We can try to help, but read the "Question Guidelines" link in my posting signature. You are not providing us with ANY useful details (version/distro of Linux, type of board, any updates lately, etc.), that would help us to help you. We can't guess.

Your system logs *MAY* have something in them, but we can't tell you whether or not to use journalctl to view them, or for you to look in /var/log/messages or the like, since we don't know what Linux you're using. Even then, if it's hardware related, there may be nothing to see.

Guess you could look closely at the boards to decide if they are in fact the same in all ways. That one may have a different chip or revision level or other soft/firmware.

How did you test that the image is exactly what you want on these boards?

Telling us what changes are in the code may help, what part of the system is affected?

Errors can go to various locations provided the board has it set to record, provided it has the ability to record. Otherwise there will be no record.

Depending on bios, it may have reports.
