Yes, we do have brown outs and are putting UPS on the system to avoid this,
so that should take care of it for now.
One other thing that we've been concerned about for a while is that
immediate shutdown could cause a problem if it interrupts a MySQL operation
or even a filesystem operation.
I don't know of anyone I could recommend, but I would think that others in
the community would have something like this.

The Power Cape http://andicelabs.com/beaglebone-powercape/ will perform
automatic switch-over to a battery on DC power failure. A script can
monitor DC power good over I2C and shut the system down as required (I
usually wait until the battery hits 3V since power here is usually restored
Thanks for your fast reply.
I've seen it on two of our boards - out of about 15. Only one of them had
a cape (the RTC cape). Any idea if that one causes the issue?
I admit that the boards are installed over in Africa where clean AC power
sources are not common. We are putting a UPS on the
We are looking at the idea that maybe the PMIC gets confused when there is
a power dip on power up, basically a power supply that can't handle
the surge when the board powers up. The idea is the PMIC
starts shutting down and then tries to power up again when the dip goes
away. I have yet to
Hello,
I saw the following on the Beagle Bone wiki page...
Improper Power DownAll Revisions
... Based on the latest information we have gathered, this appears to be an
instance where the PMIC does not power down the processor in the right
order due to the violent removal of the power
It is still an issue. We have seen it on .003% of the boards shipped. The
issue can also be related to improper design of capes that violate the
power up sequence. It may be a while before that shows up as a failure.
