Zynq 7100 PS lockup

Former Member

It appears that when I get to a certain utilization of the Z7100 device in the PL it will cause the PS to lockup where I cannot get access to the PS through the serial port.  I do see that the logic in the PL is still running using the Vivado Logic analyzer to probe some of the signals.  When I removed 20,000 LUTs then the issue goes away.  I did find a post that seems to be very similar issue I am having. "ps-freezes-when-making-use-pl"

 

I was wondering if there is any other information on this issue?

    Hello Dmitri,

    Could you supply the same information?

    1. What ATX power supply are you using?

    2. How long ago was your board purchased?

    3. Do you encounter this issue all the time? Or just sometimes? What exactly is your design doing when it happens?

    4. I would suggest you scope your power rails to make sure none are dropping out, also when doing this make sure that your trigger is set to falling edge trigger to avoid missing the capture you are looking for.

    5. Would you be willing to send me your design so I could test it out and verify the issue?

    6. Are you currently in communication with your local Avnet FAE on this issue?

    Thanks,

    Josh
