Is there a workaround for this? I thought that pre charged capacitors
could help but in my application power to the BeagleBone Black is aplied
in the same time as to the rest of the circuit.

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.
