[Arty Z7-10 Power supply issue]

That was it!  The jumper must have loosened when I was swapping wires around.  Thanks!

[Arty Z7-10 Power supply issue]

I just received an Arty and it has been working when plugged in with USB.  The ship with demo would work when I plugged it in.  It would operate the lights with the switches, would pass through the HDMI, and it would play a song on button press, and print out a serial message with a power cycle.  I switched the jumper from USB to REG, plugged in a 2.1mm 12VDC, center positive,  2.0Amp capacity wall wart, and now the only LED that turns on is LD13.  Even if I switch it back to USB, it doesn't boot up.  The serial port still shows up on device manager, but power cycling does result in a message.  Did something burn out?  Can I get a RMA to exchange it?
