What is the exact circuit that requires a fast ramp?

As Gerald has said before, check the ramp up of the power supply.
Some of the lab supplys have slow ramp ups.
Yes they are very stable and VERY good regulation but
the BBB design requires a fast ramp up supply.

Hello there,
I have a very strange problem with powering up BeagleBone Black (rev
C).... When i try to power it up from some cheap AC adapter it works
fine, but when I connect to to my labolatory power supply the power
LED on board is lid for a second and then doesnt power up the MCU and
turns off intead. I have connected both supplys to osciloscope and
they are both stable, the laboratory one even more. Why is the power
controller on the BeagleBone Black refusing to power up the MCU when
powered from lab supply? I have no idea what is this about. I would
aprichiate any help.
