Avnet Ultrazed-EV SOM: Red led when boot fails

Jump to solution

Hi Xilinx,

 I was wondering if someone could explain the mechanism of the red LED3:  PS_ERROR_OUT on the Avnet Ultrazed-EV SOM board.

I know the label says something like : there is an error on the PS side :-) but I like to comprehend what is causing the led to light up.

Because it is strange it waits 8 seconds before it get activated so I have the feeling this questions answer might pop up in the future again with our future designs.

 

The ZCU 102 has a sililar LED ( PS_ERR_OUT ) but starts to light up after 1 second.

 

Thanks for your answer,

Deville

Hi @xilinxacct 

Thanks for your help and the link. This does not quite answer my question, but I know the question was a bit vague as I did not really have a problem. 

Because it was an Avnet board I also openened a forum post there.
