I'l look at it with both a Voltmeter and an oscilloscope.
I have a B bench supply that when you turn it on, with a BBB already
attached, did an overshoot up to around 5.7 Volts before settling back to
5.0 Volts.
It would trip the self protect on the PMIC almost every time you tried to
start the
I have a static 1.5A resistive load on the supply which has a 1A minimum
load. That would leave me with 10.5 A of wiggle room. Out of which I need
just less than 2A.
I'll revisit the supply level, but I'm fairly certain that I am well within
those ranges.

Still sounds like a power problem.
A lot of 12 Amp supplies might go out of regulation at almost no load.
They typically need to be loaded to ten percent of max rated output load to
be within Voltage spec.
The Beagle supply needs to stay between 4.5 and 5.5 Volts under all load
conditions.
