The beaglebone wouldn't boot with nothing attached and just plugged into
USB, but will boot with barrel jack power.
Last night I cut off the end of a USB cord and stripped the black and red
wires. I plugged the black into P9_1 and the red into P9_5 and it boots! So
I'm not sure what I broke but
Hi,
I've had my beaglebone black working for several months using
USB power from the computer. Lately I've been using it for a project and
switched to barrel jack DC power. Now, it only works with barrel jack DC
power, and if I plug it into a computer, USB battery, or power supply
Sounds like the PMIC may have been damaged on the USB power input or the
current the board now consumes exceeds the 500mA budget on the USB. If the
later is the case, then the culprit could also be a damaged pin on the
processor somewhere.

Project? Do you have any capes attached? discrete components, ether, …?
Try removing everything, if it starts now then start adding things back on
until the problem reappears, that or a combination of the additions is usually
the problem. If the problem stays, you now have it ready for an RMA.
