Dynamically Configure FPGA From Host Program

Former Member
Former Member over 11 years ago

Hi,

I was wondering if anyone knows an efficient way to program the FPGA(PL) from a host C program (not on the SoC, but from the host PC). Is there an Xilinx API I can use/include in my program. As the only way I can think of doing it at the moment is invoking command line programming via Impact.

Basically I want to put the SDK "Program FPGA" functionality in my host C program where the user selects a prebuilt .bit file (and elf file if possible) to program the FPGA/SoC. This is just for a test of concept, later I would like to put this dynamic configuration onto on of the ARM CPU's.

Many Thanks
Sam

    You might want to take a look at this Xilinx design example:

    And why would that help him?
    (Actually he wrote: "(not on the SoC, but from the _host PC_)".)

    Unfortunately the Xilinx JTAG API is not public. The easiest way is to call impact from your software.

    Or - if you are determined - you can use the Digilent API to access the JTAG cable functions. And then you create an svf file from the programming bitfil, and with that you can program the FPGA from the host PC.
