I am currently using some beaglebone white A6 for trainings. The fact that the board is USB host powered is a bit annoying, since with some PCs USB enumeration after powering off/on takes quite some time.
Ideally I would like to operate it like the beagle-xm where I just connect a FTDI RS232/USB cable, which keeps the /dev/ttyUSBx on my host even if I power down the target board.
Do you think it’s possible to hack the beaglebone hardware in such a way that it behaves like this:
*) FTDI (only) powered over USB cable
*) board powered over 5V barrel plug
and if so what would I need to do?
Currently I have a rather complex solution where I need to switch on/off remotely:
*) 5V barrel plug
*) power which comes over USB cable
*) RESET button
All this is used for a remote setup where you don’t need to have physical access to the board.
