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 its mini-usb connector to a computer. The problem does not happen if 12V power connector is also empoyed. (Note: the example attached below is for RC1, but RC2 is no different) I can't say if such problem was also present in previous version of u-boot or not.
Thank you,
Regards, Nikolai
