i try to change the frequency on PL on ZYNQ -7020
i use Xillinux as an Os on Zedboard, i have an application, and i want to use more perfermonce for communication between PS and PL, so to set it's, there is a documentaion on Xillybus website, i fount problem to implemente thise change.
source file: ( the PDF file )
so i hope that xillinx support team, can help me to set this parametre

What is the problem? On a Zedboard, there is the Zynq device, and not an Artix-7 device. That Zynq device does use the same FPGA fabric as an Artix device, but all 7 series devices have the same FPGA architecture.
The Zynq device has the processor sytem, and the programmable logic section.
The HP ports run at 200 MHz, maximum (if I recall) on this board.
There are larger Zynq devices which may run their HP ports at 250 MHz (but that device is not on the Zedboard,

thank you for reponse,
but i check on xps, i found the max frequency clock of the PL is 250 Mhz
