The PMIC
IC in the Beaglebone will force quit the BBB if the 5V line
is above 5.5 Volts or below 4.5 Volts, even for a few
milliseconds.
So, if you want to
to have a happy BeagleBone Black, keep your BBB 5 Volt power
input between 4.75 and 5.25 Volts, to give yourself some
safety margin for power noise, etc.

steady at 5V. 4V is not going to work very well. You can try
adding some bulk capacitance across the connections. Maybe
10uF to 20uF and add a 0.1uF as well..

Hello Gerald.
DC-DC converter is stable at
five volts in almost time, but there are some events that
looks like this picture. (voltage is under 4
volts.)

exactly 5V? How much ripple is there on the 5V supply? What
is the power source for the DC DC converter?

Hello
Wulf
My beaglebone is
powering in P9_5 and P9_6 pins from DC DC converter that
supplies 5V from battery (charger controller).

project is get many measurements from differents
sensors like
conductivity, dissolved oxygen, and others. and put
this values
into web server using mobile broadband. The problem
is that
system is shuting down. I looking in log files I
don't get many
information. the most relevant information that i
got is in
