BBB does not reboot afer some successive reboots

Hi everybody,

I have a problem with a successive reboot of the BBB.
I put a watchdog script which verifies continuously if the application under the BBB runs well. After a number of fails, the watchdog forces the reboot of the BBB.
However, the BBB does not reboot after a random number of successive reboots. So, we need to boot it manualy (disconnect and reconnect Ethernet cable because the BBB is powered by POE).

Anybody knows if there is a security mechanism which prevents the restart of the BBB? or if the fail of the reboot is caused by something else.

Hi May, how are you?

I’m stuck with same trouble that you describes, do you have any advance?

Another question, do you have connected any device trough any serial port? I have a GSM modem attached to one serial port (not the console port), and I guess that modem sending data when BBB rebooting causes that BBB entering in bootloader or bootup menu or something like that, but I’m not sure…

The heartbeat led stop flashing in your board when it is in that state right?

Thanks in advance!

Stuck with the same problem… Reboot shuts down all my daemons but the BBB just… doesn’t reboot!
This is a big problem because i can’t reach my remote BBB anymore.

Did someone find a solution?

My issues were fixed by changing u-boot to not “stop on any key”. Details here.
