Change PL clock setting in Linux on ZC702 board

Hi,

 

I am running the xilinx provided Linux Kernel on ZC702 board with our FPGA logic.  We can set the PL clock using ps7_init.tcl script for standalone mode. But not sure what is the proper way to do it in Linux.

 

Currently, we modified register F8000170 and F8000180 through /dev/mem mapped IO.  It works.  However, we would like to know what is the proper way to set PL clock in Linux.

 

Regards,

Q.Li

You have probably figured this out already, but maybe for others: you can configure PLL dividers in the FSBL by editing the register settings in ps7_init.c
