the thing is that I already have a BBB and I need to do rather

Hi,
I need to disable the BBB from booting when usb is connected to the PC. I
have an external supply that powers the BBB as well as other things. I
would like the configuration such that even if a user connects to the BBB
via USB it will not boot until the 5V main power supply is turned on.
We have no instructions on how to break the board.The TPS65217C
is designed to power the board from either of these sources, whichever one
come first. If 5V is connected it switches to 5VDC when connected.
One way to do what you want is to remove the power connection in your
cable, cut the wire.
let me share my experience (problems).
1. the card can be 4gb but the use of the card it must be the sice of the
bbb memory 2gb
2. when you restore is not ok to use any thing else (usb share, ethernet,
linux session). just dont do any thing just press the boot bottom.
3. try more than one time.
Gerald,
Thank you for the reply.
A hypothetical thought-experiment question... if the trace that sends
USB_DC to Pin 12 of the TPS65217C is absent yet still goes to the processor
(P15) would that disable the USB 5V sense of the TPS65217C yet still allow
the processor to recognized the USB
