I just received my Arty board and it powers up and works just fine over the USB power but when I switch to the barrel connector (and change J13 - the source jumper) it does not power on. It appears to be related to the ADP2384 (IC12) not functioning properly. I used my multimeter and probed around the supply and I see 12.5VDC (the output of the supply I'm using) at the tips of the barrel connector as well as at the inputs on the capacitors on the source side of the ADP2384. However, when I probe the output side of the ADP2384 I am getting output in the small milli-amp range (looks like raw leakage current).
Is this a known issue? Is there some other jumper I'm supposed to be setting besides just J13?
