ZynqMP: GPIO pins for Ethernet/USB/etc. PHY Reset

Jump to solution

Hello,

I have a custom Zynq Ultrascale+ board with some GPIOs (MIO) used for PHY Reset (Ethernet, USB, ...). I found this Zynq-7000 forum entry with pictures showing how to set MIO pins as reset pins. But I cannot find similar settings in my Vivado 2018.2 for ZynqMP.

Can someone give me a hint?

Thanks,

Ralf

u willhave to move to latest vesrion.

for some reason if you are not able to move, then plase use GPIOs to trigger the reset. In the PCW GUI please enable GPIO and assign MIOs as needed and setting of value should be taken care in the application
