MicroZed randomly resetting

Former Member

Microzed randomly resets.  Rarely running more than 24 hours.  Sometimes resetting every few minutes. 

Reset frequency possibly a function of activity.  MicroZed powered from USB.  Maybe some power valid sensor is triggering a reset??

Anybody else seen this?

    I am seeing the same results on 2 microZed Rev C boards that I have.  It appears stable when I run one with the default linux image connected to the usb port of my pc.  If I load aa fpga image in this configuration, it seems less stable (restart happens about the frequency llj describes. 
    I have built a carrier board and when I run my microZed on this card, it happens VERY frequently (every 20s to couple of minutes).  I'm not really sure how to go about diagnosing this problem to fix it.  Are there any other reasons the microZed would reset besides power fluctuations?
