Interfacing in XPS and SDK

Former Member

Hi all,

I am trying to run code on both the ARM core and FPGA in my Zedboard. I plan to run a C code on ARM and run a Verilog code on FPGA, with the C code calling the Verilog code. How do I create an interface within my C code such that it will call the Verilog code ? Should I create pointers in the C code and use the address of AXI ?

    Hi, first of all you have to create fpga module in XPS using Verilog. You can see how to create custom IP on ZynqGeek blog (just change one option to create template file in Verilog instead in VHDL).
    After you create and add your module in your system, export hardware to SDK. Here you will program ARM PS in C. If you didn't create template drivers you can communicate with module by Xil_In and Xil_Out functions (in xil_io.h library)
