OK. I'll be glad to gather any data for you that I can. I can grab some scope traces of what the power looks like. I don't have anything that will do 24 hour long captures.
The bench supply I have is well regulated, and quiet, 5 Amp. I have run two PB (on Vin P1-pin1) from the same supply simultaneously. The PBs are both rebooting at very different times, randomly, at the rate of three or four times per day. I will bridge a BBB and some bulk capacitance across the feed, and re-run the experiment. I am fairly sure this is not an input side power problem. --- Graham == On Wednesday, December 13, 2017 at 1:05:13 PM UTC-6, Jason Kridner wrote: > > Can you generate a plot of the power applied on P1_1?
