Hi all,

I'm observing that the said A20-onlinuxino-micro board hangs in U-boot in probing USB2 (see example below) in case it is powered by connecting

I think it's normal. During the boot, u-boot initialize the usb otg, and for a fraction of second the power is disconnected. I solved it by attaching a battery (and I have a PSU as a side effect :) ).
