Ok that’s interesting. Thanks for the feedback
But if there is no power applied to the VDD_CAPE pins and you connect the USB
cable then it will power from USB is that how it behaves?
I don’t want the device to power from usb at all, I only want usb for
connecting devices.

Yes it boots as usual without USB power, I use it as a USB gadget, so I
regularly connect/disconnect the USB-C connector while being powered over
the pins.
It does not reboot, and there's no momentary glitch either, so as long as
one of the two power sources is connected, it runs continuously.

Does it boot the board as soon as you apply power and without the usb
connection?
What happens when it is powered up then you connect the USB?

I've not yet removed the diode, but otherwise I'm powering my BBAI using a
5V/3A power supply (from OKdo) through pins P9.1+2/5+6.
I read in some topics (like
https://groups.google.com/forum/#!topic/beagleboard/Tx9pGjJPZ0A) that one
might need a beefier supply or added cap if not powering thru
I connected pin1 to GND and pin5 for VDD_CAPE
As pins 5 and 6 are connected on the PCB I did not see it necessary to
connect power to both pins.
have you successfully self powered one of these boards?

Do you use pins 5&6 (VDD_CAPE_5V) to power the board?

When i removed D81 power was present on VDD_5V but only at about 4.5V which
is I guess the voltage drop across D82.
there was no voltage on VDD_3V3 and the device would not startup - even
after pressing the power on button.
Has anyone solved this?

I have found D81 from the silk screen data. Will be removing and trying as
a next step.

Hi Geza,
I was wondering if you made any progress here?
I took a look at the schematics myself and I agree that by removing D81 you
essentially disconnect VDD_TYPE C from VDD_5V.
If you then apply 5v power to VDD_CAPE_5V it connects to VDD_5V through D82
and should power the device.

Is there still bus powered and self powered devices in USB-C?
Are there signals equivalent to OTG ID?

There's no such things as data only USB cable, the 5V is part of the
signalling.

Adrianne,
I have heard of USB Cables and USB Charging cables but not a USB Data only
cable.

Hi
I would also like to do the same. I had hoped this could be done in the
configuration as opposed to a hardware change.
Geeza - have your tried a "data only" USB cable?
