ZU + USB3 overcurrent polarity

Jump to solution

Hi,

 

in what document us zynq ultrascale documented?

 

USB3 IP core has overcurrent on emio pins, are they active low or active high?

 

I would assume such information is something that the users should know, but it is not in RTM and not in any other document I have found so far.

I guess I changed to the level from default or what I expected to the opposite. It may also be that is was problem until I installed the ZU tactical patch for 2015.4.1, most likely fixed in 2016.1, I have not yet checked that.

 

so unless you have the same issue, do nothing, if you see overcurrent, change the EMIO level.

 

currently I have the usb emio signals DISABLED and it is OK
