Hi,
24.12.2018 20:32, Diego Roversi:
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 :) ).
Ah, got it. Thats a funny issue then. Its not the software to blame. Ok.
(Ideally, this peculiarity should probably have been mentioned by Olimex
in their docs, but maybe I've overlooked it.)
Solved it for now by disabling USB altogether.
Thank you,
Regards,
Nikolai
Regards,
Diego.
