I can no longer connect to my Zybo Z7-10. About an hour ago I tried to load a project on Vivado SDK, and it wasn't able to connect to the board. I restarted SDK, power cycled the board a few times, reconnected the usb cable, and also restarted my computer, and it still wasn't able to connect. I then tried using the hardware manager in Vivado to auto connect to it, and it didn't work. I've tried powering it with both the usb cable and a 5V wall adapter. I've tested the wall adapter and it's working fine.
After I gave up on connecting to it, I tried to run the demo project by switching the programming jumper to the QPSI position. The demo project didn't run, but I noticed that the red LED (PGOOD) was a little dimmer. Every time I powered up the board I can very clearly see that the red LED was getting weaker and weaker. As I'm writing this post, the LED is pretty much off (I can barely see a faint glow when I cup my hands over it). The LED is not entirely dead, when I use my multimeter to test continuity, the LED blinks briefly when I probe it. I didn't see or smell any smoke, and none of the large components felt warm when I powered up the board. I don't see any burn marks or cold joints on the board. I've probed the 5V rail, it is getting power from the wall adapter and it isn't shorted to ground.
This board was working fine an hour ago. The last project I compiled was an HDMI processor with a sink and source.
Did I accidentally burn my board? This board is just over 3 months old, is it covered by some kind of warranty?
EDIT: Probing that red LED gives me 3.3V on one end and about 1.7V on the other.
