Zedboard power up fail

blake_ding

Hi sir,

When I power on the Zedboard, the LD13(power) doesn't light and LD0 ~ LD7 all RED.

The only action was that I shorted the 3.3V of J18.
After that, the Zedboard seems crashed?

Could I reset it by myself?

    You shouldn't need to solder anything on ZedBoard (I guess unless J18 was missing, but it should be populated). You need to install a jumper from pin 1-2 on J18 to set the output to 3.3V

    The issue with replacing IC27 is that if it indeed failed, what made it fail? There could be a short on that plane somewhere so it wouldn't fix anything replacing the device, it would just result in the new device shorting as well.
