I have two PocketBeagles.
Both are exhibiting random reboots, two to four times per day. No
indication in syslog as to any cause or problem. No pattern to
the reboots. Can happen while I an logged into the PB editing python
scripts with nano, or can happen in the middle of the night when
absolutely nothing is happening.
Both are powered from Vin, running from a trusted lab bench supply
with plenty of reserve current. I have added extra bulk capacitance on
the Vin input, and also switched lab bench supplies to make sure it
was not a power supply problem.
So, no USB-gadget interface running.
No modifications to hardware or kernel. No modifications to the
One is running the Oct 10 IoT release version
Linux PB1 4.4.91-ti-r133 #1 SMP Tue Oct 10 05:18:08 UTC 2017 armv7l
The other is running the Stretch IoT weekly snapshot from 11-19
Linux beaglebone 4.9.61-ti-r76 #1 SMP PREEMPT Mon Nov 13 20:24:26 UTC 2017 armv7l
Both are running USB2 to Ethernet dongles on USB Port1 so I can have
remote Ethernet access. To make sure it was not the USB-to-Ethernet
drivers, I ran one for a day, without the Ethernet interface, just
watched it on the UART0 Console Port, no programs running,
and it still does the same thing.
I think this should be easy to reproduce.
Same/similar symptoms to the random reboots we were having on the BBB a year or two ago.
